Full textAbstract:
The ROMS is used to investigate the oceanic circulation in the Delagoa Bight region, near the southwestern end of the Mozambique Channel. The model is initially configured at a horizontal resolution of 1/10° (9.9km) over the domain 30.1-43°E,22.13-30.8° S. Subsequent configurations nested an inner grid of resolution 1/30° (3.3km) over the region 32.43-36.43°E,24.09-27.71°S Several sensitivity experiments were performed with and without the inner grid or with or without tidal forcing. Using only the outer coarse resolution grid, the first experiment (DELAGI) does not include tidal forcing whereas tides are included in the second (DELAG-II) experiment. DELAG-III and DELAG-IV both use the inner higher resolution grid but exclude and include tidal forcing respectively. The model was evaluated against observations, namely the WOA, Pathfinder SST and AVISO SSH. The results showed that ROMS adequately resolves the oceanic features in the region, namely the pathways of the anticyclonic eddies from the northern Mozambique Channel and from Madagascar, and the instances when the DBLE is present or absent. The model is also able to reproduce the main water masses and their sources in the region. Water masses found in the centre of the Bight enter through the northeastern sector, either by intrusion of pulses or instabilities of the southwards flowing current. When the DBLE is well established, upwelling is likely to contribute to the water masses in the lower layers. The transport of water towards the Bight from the east was found to be less than that from the north. The model also succeeds in representing the thermocline structure of the DBLE but it fails to capture the local salinity maximum. When tidal forcing is included, the speed of the flow close to the coast increases. The model also revealed the influence of the Inhambane Cyclone on the Delagoa Bight as well as on the region to its south. This cyclone, which is generated in the flow near Inhambane, is similar to Natal Pulses which occur in the Agulhas Current. An eddy detecting and tracking system was used with both the model outputs and VISO SSH to determine the statistics of the DBLE, namely its dimensions, amplitudes and life-times. A maximum radius of 59.52 km, life span of 126 days and an amplitude of 27.27 cm were found. It was also demonstrated that this feature is generated northeast of the Bight. When the inner grid was included in the simulations, anticyclonic features were generated within the Bight with a maximum diameter of 85.4 km and life span of 12 day. These anticyclonic features dominate the circulation when the DBLE is absent (less than 30 percent of the total period of the simulation). The possibility of several cyclonic cores existing simultaneously in the Bight was also demonstrated. Two cores were found with life spans of more than 12 days. When the number of cores is greater than two, they tend to be short lived. Analysis of energy conversion rates showed that the generation of both the DBLE and the Inhambane cyclones is mainly by barotropic instabilities, although in both regions of their generation, weak baroclinic instabilities were also found.

Full textAbstract:
Description of the shelfbreak front in the Middle Atlantic Bight is hampered by the extreme variability of the front. In order to gain more insight into the mean frontal structure and associated baroclinic jet, historical data is used to produce two dimensional climatological fields of temperature and salinity for the region south of Nantucket shoals. Associated cross-shelf fields of density, geostrophic velocity, relative vorticity, and shallow water potential vorticity have also been computed. Historical data from a quality- controlled database (HydroBase) in the region 69-72 deg W, 39.5-41 deg N is included. Cross-shelf sections are obtained by averaging the data in nine depth bins with an average cross-shelf spacing of 10 km but an increased resolution of 4 km near the shelfbreak. The vertical averaging interval was 10 m over the shelf and upper slope waters, increasing to 50 m in the deep slope waters. The data were averaged in bimonthly periods to study seasonal trends. For inter- regional comparison, similar analyses were performed for the south flank of Georges Bank and the shelf off New Jersey. The climatological temperature and salinity are consistent with previous descriptions of the frontal hydrography. Most importantly, features such as the cold pool, the upper slope pycnostad, and the frontal boundary are well resolved when compared with synoptic sections. The temperature contrast across the front varies seasonally between 2-6 deg C near the surface and at depths of 45-65 m. The salinity contrast is 1.5-2 PSS, with little seasonal variation. The resulting cross-frontal near surface density gradients are strongest during the winter and weakest during the summer, when the seasonal thermocline is established

Full textAbstract:
The Great Australian Bight (GAB) is an extensive W-E striking continental margin basin that drifted northwards during the Cenozoic following rifting and separation from Antarctica in the mid/late Cretaceous. Seafloor spreading accelerated in the mid-Eocene and was associated with local volcanism. The mid-Eocene succession of the GAB is conspicuously mounded and separates a dominantly siliciclastic succession below from a fully marine carbonate succession above. The mounded succession was penecontemporaneous with major changes in global climate, oceanographic conditions and tectonic re-organization in the region, and thus may hold important clues as to the palaeo-environmental changes associated with these changes. The mid Eocene has so far only been described locally or in passing, usually by studies focused on either the siliciclastics below or the carbonates above. It was therefore chosen as a major focus point for the research project reported herein. Exploration activity in the GAB has been limited despite the presence of a working petroleum system and large target structures, but industry interest has increased over the past few years leading to 3D seismic surveys being acquired in the GAB. The focus for exploration is the Cretaceous succession beneath the relatively thin Cenozoic cover, which however, is still important in terms of shallow hazards and as overburden to the anticipated productive sections. As is often the case, the new 3D seismic data shows many overburden features in great detail and thus affords new insights to be gained that improve our understanding of the post-rift evolution of the marginThis thesis expands upon and reinterprets a pre-existing sequence framework in the Cenozoic GAB based from ODP Leg 182 results. A vast database of 2D and 3D seismic surveys has been integrated with exploration wells and borehole data and several surfaces have been calibrated to borehole and well constraints, then mapped to the maximum lateral extent across the available dataset. Surface mapping provided new insight into sequence deposition and palaeoenvironmental settings. Structure maps and thickness maps highlight key depocentre locations and trends over the Cenozoic GAB as well as stacked mass debris aprons. The newly discovered sequences raise new questions regarding trigger mechanisms in a-seismic areas and feed into industry geohazard perception models. The base surface of the Cenozoic framework hosts a plethora of mounded features across shelf and basinal section. All mounds within the dataset have been mapped. A set a bryozoan reef mounds have been interpreted lying parallel to the margin as linear complexes over 500 km. They coincide with the underlying siliciclastic delta clinoform breakpoints and provide insight into the changing palaeoenvironment at the 43 Ma mark, cessation of siliciclastics and regional marine transgression. Further mound mapping aided by 3D attribute extractions along the base Cenozoic unconformity led to the interpretation of a series of enigmatic igneous-based mounded features. The discoveries have been included in a comparative study, comparing all mounded features (igneous or carbonate) and contrasting their individual characteristics of geometry, seismic facies, dimension in order to understand mound origin and emplacement. A new grouping of mounds in the GAB has been established, the origin and emplacement mechanisms of which contribute to the global knowledge base.

Full textAbstract:
A high-resolution astronomic tidal model has been developed that includes detailed inshore regions of the Atlantic Intracoastal Waterway and associated estuaries along the South Atlantic Bight. The unique nature of the model's development ensures that the tidal hydrodynamic interaction between the shelf and estuaries is fully described. Harmonic analysis of the model output results in a database of tidal information that extends from a semi-circular arc (radius ~750 km) enclosing the South Atlantic Bight from the North Carolina coast to the Florida Keys, onto the continental shelf and into the full estuarine system. The need for tidal boundary conditions (elevation and velocity) for driving inland waterway models has motivated the development of a software application to extract results from the tidal database which is the basis of this thesis. In this tidal toolbox, the astronomic tidal constituents can be resynthesized for any open water point in the domain over any interval of time in the past, present, or future. The application extracts model results interpolated to a user's exact geographical points of interest, desired time interval, and tidal constituents. Comparison plots of the model results versus historical data are published on the website at 89 tidal gauging stations. All of the aforementioned features work within a zoom-able geospatial interface for enhanced user interaction. In order to make tidal elevation and velocity data available, a web service serves the data to users over the internet. The tidal database of 497,847 nodes and 927,165 elements has been preprocessed and indexed to enable timely access from a typical modern web server. The preprocessing and web services required are detailed in this thesis, as well as the reproducibility of the Tidal Toolbox for new domains.ID: 029808889; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Thesis (M.S.)--University of Central Florida, 2011.; Includes bibliographical references (p. 182-184).

Cross, Cheryl L. "Predictive Habitat Models for Four Cetaceans in the Mid-Atlantic Bight." NSUWorks, 2010. http://nsuworks.nova.edu/occ_stuetd/221.
Full textAbstract:
This study focuses on the habitats of cetaceans in the Mid-Atlantic Bight, a region characterized by bathymetric diversity and the presence of distinct water masses (i.e. the shelf water, slope water, and Gulf Stream). The combination of these features contributes to the hydrographic complexity of the area, which furthermore influences biological productivity and potential prey available for cetaceans. The collection of cetacean sighting data together with physical oceanographic data can be used to examine cetacean habitat associations. Cetacean habitat modeling is a mechanism for predicting cetacean distribution patterns based on environmental variables such as bathymetric and physical properties, and for exploring the potential ecological implications that contribute to cetacean spatial distributions. We can advance conservation efforts of cetacean populations by expanding our knowledge of their habitats and distribution.
Generalized additive models (GAMs) were developed to predict the spatial distribution patterns of sperm whales (Physeter macrocephalus), pilot whales (Globicephala spp.), bottlenose dolphins (Tursiops truncatus), and Atlantic spotted dolphins (Stenella frontalis) based on significant physical parameters along the continental shelf-break region in the Mid-Atlantic Bight. Data implemented in the GAMs were collected in the summer of 2006 aboard the NOAA R/V Gordon Gunter. These included visual cetacean survey data collected along with physical data at depth via expendable bathythermograph (XBT), and conductivity-temperature-depth (CTD) instrumentation. Additionally, continual surface data were collected via the ship’s flow through sensor system. Interpolations of physical data were created from collected point data using the inverse distant weighted method (IDW) to estimate the spatial distribution of physical data within the area of interest. Interpolated physical data, as well as bathymetric (bottom depth and slope) data were extracted to overlaid cetacean sightings, so that each sighting had an associated value for nine potentially significant physical habitat parameters.
A grid containing 5x5 km grid cells was created over the study area and cetacean sightings along with the values for each associated habitat parameter were summarized in each grid cell. Redundant parameters were reduced, resulting in a full model containing temperature at 50 m depth, mixed layer depth, bottom depth, slope, surface temperature, and surface salinity. GAMs were fit for each species based on these six potentially significant parameters. The resultant fit models for each species predicted the number of individuals per km2 based on a unique combination of environmental parameters. Spatial prediction grids were created based on the significant habitat parameters for each species to illustrate the GAM outputs and to indicate predicted regions of high density. Predictions were consistent with observed sightings. Sperm whale distribution was predicted by a combination of depth, sea surface temperature, and sea surface salinity. The model for pilot whales included bottom slope, and temperature at 50 m depth. It also indicated that mixed layer depth, bottom depth and surface salinity contributed to group size. Similarly, temperature at 50 m depth was significant for Atlantic spotted dolphins. Predicted bottlenose dolphin distribution was determined by a combination of bottom slope, surface salinity, and temperature at 50 m depth, with mixed layer depth contributing to group size.
Distribution is most likely a sign of prey availability and ecological implications can be drawn from the habitat parameters associated with each species. For example, regions of high slope can indicate zones of upwelling, enhanced vertical mixing and prey availability throughout the water column. Furthermore, surface temperature and salinity can be indicative of patchy zones of productivity where potential prey aggregations occur.
The benefits of these models is that collected point data can be used to expand our knowledge of potential cetacean “hotspots” based on associations with physical parameters. Data collection for abundance estimates, higher resolution studies, and future habitat surveys can be adjusted based on these model predictions. Furthermore, predictive habitat models can be used to establish Marine Protected Areas with boundaries that adapt to dynamic oceanographic features reflecting potential cetacean mobility. This can be valuable for the advancement of cetacean conservation efforts and to limit potential vessel and fisheries interactions with cetaceans, which may pose a threat to the sustainability of cetacean populations.

Full textAbstract:
A high-resolution, finite element-based, shallow water equation model is developed to simulate the tides in the South Atlantic Bight. The model is constructed to include all of the estuarine features along the southeastern United States seaboard: coastal inlets, rivers and tidal creeks, sounds and lagoons, intertidal zones including salt marshes and mangrove swamps, and the Atlantic Intracoastal Waterway. The estuaries are represented in the finite element mesh using triangular elements with side lengths on the order of tens of meters. Also incorporated into the model is a spatially distributed bottom friction parameterization, based on the various landcover and benthic characteristics in the domain. The motivation to use this comprehensive representation of the system was inspired by a desire to capably account for the full estuarine tidal physics. In this approach, no calibration is performed and the model is used as a tool to assess the physical processes it describes. Upon its development, the model is first validated by accurately simulating tidal hydrodynamics in the South Atlantic Bight including the described estuaries. Variants of the model are then constructed by selectively removing estuarine features from the domain. All model representations are subsequently applied in nearly identical simulations: the only differing factor between the simulations being the inland extent of the estuaries described. The solutions are compared with respect to including versus excluding the estuarine features of the domain. Where water surface elevations are shown to be unaffected by the estuarine features of the South Atlantic Bight, tidal velocities exhibit far more sensitivity. This effect is pronounced locally, with regional effects extending offshore. Further analysis is performed on cross-sectional flows recomposed locally and on tidal energetics diagnosed throughout the domain. It is discovered that the high frictional environment of the vast estuarine surface area plays a role in local and regional tidal circulation in the South Atlantic Bight.Ph.D.

Full textAbstract:
Submarine canyons can impact regional oceanography and provide a conduit for shelf-slope exchanges via topographically induced processes such as canyon upwelling and downwelling. Between Virginia and New York in the Mid-Atlantic Bight (MAB), there are five major shelf-incising canyons (Norfolk, Washington, Baltimore, Wilmington, and Hudson canyons) and four sizable slope-confined canyons (Accomac, Spencer, Lindenkhol, and Toms canyons). Canyon upwelling and downwelling at these canyons have not been well studied. Consequently, the associated hydrographic variability and dynamics inside the canyons and on the adjacent shelf are largely unknown, and the integrated impact of submarine canyons on MAB shelf hydrography and shelf-slope exchanges is poorly understood. This dissertation was inspired by a glider-based survey at Wilmington Canyon, and mainly used numerical modeling simulations for the MAB with an unstructured-grid three-dimensional ocean model to answer these questions. Using glider observations and realistic numerical modeling for February 25–March 7, 2016, Chapter 2 investigated the hydrographic variability associated with the Wilmington Canyon and adjacent outer shelf and shelf-break amid two consecutive events of upwelling and downwelling. Then focusing on the same Wilmington Canyon upwelling and downwelling events and using a realistically forced numerical modeling simulation as well as one without tidal forcing, Chapter 3 tested the dynamical drivers of winds and tides in canyon upwelling and downwelling events, also compared the differences in dynamics between the canyon and adjacent shelf-break. Chapter 4 presented the occurrences and integrated impact of 12 cycles of spatially coherent upwelling and downwelling through nine canyons between Virginia and New York, based on a realistic numerical modeling experiment and a No-Canyon experiment for January 1–April 14, 2016. Chapter 4 also analyzed the frequency of canyon upwelling and downwelling based on a 22-year record (1994–2015) of sea surface elevation. This dissertation found that the submarine canyons in the MAB induced significant spatial and temporal hydrographic variabilities on the shelf and enhanced shelf-slope water exchange. Due to favorable winds, sea surface tilts, and shelf-scale background ocean currents, as well as canyon topography, cycles of spatially coherent multi-canyon upwelling and downwelling frequently occurred in the MAB. Plumes of upwelled slope water from the canyons intruded the outer and mid shelf during the upwelling episodes, and dense water from the shelf retreated into the canyons during the downwelling episodes. For each cycle of upwelling and downwelling, upwelled water from the canyons caused shelf-scale anomalies of low temperature, high density, and northeastward velocity on the MAB outer shelf that were significant when averaged over the course of the season. This thesis suggests that submarine canyons are an integral part of MAB oceanography and deserve further investigations.

Full textAbstract:
Continental shelves are generally believed to play a critical role in ocean biogeochemical cycling, however this has raised the question as to the relative importance of various nitrogen flux terms such as denitrification, burial, net community production and advective fluxes. Quantifying these fluxes on an annual area-integrated basis using traditional observational means is often difficult, due to the fact that these fluxes rapidly change on relatively small spatial scales, making inadequate data resolution a significant problem. Satellite remote sensing data and numerical modeling provide alternative ways to fill the data gaps, and hence have the potential to generate quantitative estimates of these various biogeochemical fluxes. However, they both suffer from distinct shortcomings, e.g., satellite data are only limited to the surface whereas numerical modeling can be pointless without rigorous skill assessment. Thus caution is warranted when using these tools to generate quantitative estimates of biogeochemical fluxes. The two were combined in this dissertation project by assimilating the satellite-derived data into the models, selecting the optimal ecosystem model, as well as evaluating the model before using the model simulations to explore the nitrogen fluxes on the Mid-Atlantic Bight (MAE). First, multiple satellite-derived data products were assimilated into a one-dimensional assimilative model framework to determine the relative advantages of assimilating different satellite data types. The variational adjoint method, a parameter optimization method, was applied to a series of experiments assimilating synthetic and actual satellite-derived data, including total chlorophyll, size-fractionated chlorophyll and particulate organic carbon (POC). The experiments revealed the importance of assimilating data from multiple sites simultaneously as the optimal parameter sets produced by assimilating data at individual sites were often unrealistically over-tuned and deteriorated model skill at times and depths when data were not available for assimilation. The model-data misfits from the experiments also demonstrated that optimal results were obtained when satellite-derived size-differentiated chlorophyll and POC were both assimilated simultaneously. These two types of satellite data were then assimilated simultaneously to rigorously evaluate how food web model complexity affects the ability of a lower trophic level model to reproduce observed patterns in satellite-derived data. This was again implemented in the one-dimensional model framework to minimize the computational costs. Five ecosystem model variants with various levels of complexity in the phytoplankton (P) and zooplankton (Z) structures were examined by assimilating satellite-derived size-differentiated chlorophyll and POC data at four MAE continental shelf sites, and testing the optimal parameter values at five independent sites in a cross-validation experiment. Although all five models showed improvements in model skill after the assimilation, the moderately complex 2P2Z model best reproduced the surface fields throughout the MAE. Additional experiments were conducted in which random noise was added to the satellite data prior to assimilation. Whereas the most complex model was sensitive to the random noise added to the data, the simpler models successfully reproduced nearly identical optimal parameters regardless of whether or not noise was added to the assimilated data, highlighting that random noise inherent in data into these simple models. The moderately complex 2P2Z ecosystem model was thus coupled with a three-dimensional circulation model and forced by a dynamic land ecosystem/watershed model to simulate the biogeochemical cycling on the MAB shelf and to quantitatively assess key components of the annual area-integrated nitrogen budget from 2004-2007. The simulation indicated that over these four years similar amounts of nitrogen were removed by denitrification and burial (∼0.1 Tg N y-1). Net community production was larger and varied more between the four years (∼0.2 to 0.3 Tg N y-1), but overall was positive, indicating that the MAB was net autotrophic. The advective fluxes of nitrogen into and out of the MAB were dramatically different between the four years investigated (by about ∼.26 Tg N y-1), presumably as a result of changes in the positions of the Gulf Stream and Labrador Sea waters. The accumulative effects of these fluxes resulted in a near zero net rate of change in total nitrogen, indicating the MAB remained unchanged in the amount of total nitrogen in the water column over these the four years. Sensitivity tests varying the initial conditions and simplifying the modeled plankton structure showed distinct impacts on these nitrogen fluxes: the former strongly affected the advective fluxes, but had little impact on denitrification, burial or NCP, whereas the latter significantly reduced denitrification, burial, and NCP but did not significantly impact the advective fluxes. Overall the strong seasonality and interannual variability in the nitrogen fluxes highlight the importance of data coverage throughout all seasons and multiple years in order to accurately resolve the current status and future changes of the MAB nitrogen budget.

Full textAbstract:
The coastline of the Canterbury Bight between Timaru and the southern end of Kaitorete Barrier is in long term erosion. Paradoxically, alluvial cliffs and several large, braided rivers drain from the rapidly eroding Southern Alps into the Canterbury Bight, transporting indurated sandstone of the Torlesse Supergroup, or greywacke, to the coast. Catchment specific sediment yields average 1856 ± 261 t km-2yr-1 compared with the world average of 182 t km-2yr-1 and are among the highest known specific sediment yields in the world. The large sediment loads from these Canterbury rivers are comprised predominantly of fine sediments as suspended load (more than 90%), with only a small proportion of coarse bedload (less than 10%), which is reflected in the nature of the mixed sand and gravel beaches. The Canterbury coastline is apparently abundantly supplied with sediment, which is transported northward forming Kaitorete Barrier. However, since the 1950's there has been very little accumulation of sediment against Banks Peninsula at the downdrift end. Previous research suggested that sediment is lost from the beaches due to abrasion.
Abrasion has been used as both a generic term and to describe a specific process of mechanical reduction. However, it is not the only process that causes sediment particle change. For this reason, the term reduction is preferred to describe the overall change to sediment particles, and abrasion is simply one process of reduction. Reduction includes both physical and chemical processes operating concurrently.
This thesis examines reduction and its impact on the mixed sand and gravel beaches of the Canterbury Bight. To do this, sediments were collected from 55 field sites along the Canterbury Bight and three series of tumbler experiments were carried out in the laboratory using a concrete mixer. Series One, identified the significant variables for the study of reduction. Other studies have considered sediment particle size a significant indicator of the rate of reduction, however, results showed that larger sizes did not always have the higher reduction rates. These experiments identified other areas that required further investigation, including sediment lithology due to the variations in reduction rates between sites, shape and variations in the quality of sediment at the coast and also suggested chemical weathering was important.
Series Two investigated the significance of textural mix to reduction, and results showed that textural mix was a more important indicator of loss than sediment size alone. Other influences identified as significant to the reduction of sediments included lithology, where variations of sediment particles provided some explanation for variations in reduction rates between sites. Shape was investigated, but results were inconclusive as to the significance of this variable to reduction. The dominance of shapes on Canterbury Bight beaches also showed that, unlike other mixed sediment beaches, there was no zonation across the beach profile.
Series Three investigated the significance of chemical weathering. Weathered and unweathered material was compared to establish the significance of the quality of sediments to reduction. The depth of weathering rinds was found to be a significant indicator of the quality of sediments, where weathered material showed greater losses than unweathered material when tumbled.
Having identified the significant variables for reduction, it was possible to develop numerical models that allowed for the application of the laboratory results in the field. A textural mix model was developed based on the textural mix of sediments. Results confirmed a high variability in reduction rates along the Canterbury Bight.
A sediment transport model, calibrated to 20 years of hindcast data, was developed to establish the distance travelled by sediment within the swash zone of these mixed sand and gravel beaches. A tracer experiment made it possible to establish the actual rate of sediment transport based on the movement of the faster pebbles in a sample.
By combining both the textural mix model and the sediment transport model it was possible to develop a sediment displacement model. This is a predictive model and provides an estimate of the amount of time it would take for the displacement of sediment from one section of beach to another. It works on the premise that what is not lost to reduction is moved by longshore sediment transport.
Finally, the thesis suggested that there was a paradox, with large braided rivers and sediments from the alluvial cliffs providing sufficient sediment to renourish the coast, yet there is very little accumulation of sediment against Banks Peninsula. So why is the coast from Timaru to Taumutu eroding? The answer is sediment displacement, where both the processes of reduction and longshore sediment transport are moving and removing the sediments from the coastal system.

Full textAbstract:
Invasive species are a top threat to global biodiversity. Lionfish (Pterois volitans/miles) are a marine invasive predator that are now established in the Western Atlantic, Caribbean Sea and Gulf of Mexico. Studies that have documented impacts of lionfish suggest they can reduce fish recruitment and native species biomass by up to 80%. Research on lionfish impacts, biology and ecology is heavily focused in tropical and subtropical systems, with considerably less research effort occurring in the temperate regions of their invaded range, such as the South Atlantic Bight. Lionfish life history estimates are important to modeling lionfish population growth, modeling future dispersal and evaluating the efficacy of different removal strategies. Since lionfish life history will vary with a suite of environmental, biological and ecological factors, estimates of lionfish life history should be collected in all regions of their invaded range. The purpose of this study was to collect baseline information of lionfish biology and ecology in the southern portion of the South Atlantic Bight, an unstudied region for this species. As such, chapter one uses a quantitative approach to determine lionfish life history estimates important to management. Some important results of chapter one are: lionfish are recruiting at one main time throughout the year, growth changes seasonally and the population is relatively young (< 3 years of age). Chapter two takes the first step in determining lionfish impacts in this region by quantifying their diet. The main conclusion of this chapter is that round scad (Decapterus punctatus), sand perch (Diplectrum formosum) and black sea bass (Centropristis striata) are the most important prey items in the lionfish diet. Black sea bass are an important fishery in the South Atlantic Bight, and lionfish could be negatively affecting recruitment. Together, these chapters provide important insight into lionfish ecology in this region and in general.

Full textAbstract:
An accurate understanding of global patterns through geologic time depends upon multi-scale analyses of spatial variation within narrow temporal intervals. This work investigates geochemical and paleoecological patterns in modern brachiopod faunas which may serve as analogues for ancient brachiopod assemblages. The paleoclimatic utility of delta18O in the phosphatic phase of lingulid brachiopod shells requires valve secretion in equilibrium with seawater, an assumption tested (and rejected) when analyzed at scales ranging from millimeters to kilometers. By contrast, biological encrustation of the brachiopod fauna of the Southeast Brazilian Bight shows strong sensitivity to microenvironmental conditions such as host identity, shape, and size, and may prove useful for studies of ancient planktonic productivity. Comparison of encrustation patterns on naturally occurring brachiopods and bivalves collected from the same sites, and occupying the same size range, demonstrates that the results of encrustation studies on modern bivalves cannot be directly applied to ancient brachiopods. However, careful comparisons may reveal patterns of epibiont selectivity and the impact of changes in the relative abundance of host shells through geologic time. Finally, neither epibiont abundance nor diversity increase with host age as indicated by dated brachiopod shells from the past 1000 years. These results suggest that the temporal resolution of epibiont assemblages matches their spatial resolution, and strengthen evidence for competition among encrusting taxa. By documenting geochemical and paleoecological variation within shells and across a continental shelf, this work demonstrates the importance of understanding spatial variation across all scales before interpreting trends through time.Ph.

Full textAbstract:
57 synthetic aperture radar (SAR) images were collected over the Mid-Atlantic Bight (MAB) during the Shallow Water 2006 experiment (SW06). The dependence of internal wave (IW) signature occurrences and types in SAR images on the wind conditions is studied. A defined signature mode parameter (S sub m ) quantifies the signature of the IW intensity profile in relation to the mean backscatter in the image background to determine different IW types (single positive, single negative and double sign). The statistical results show that moderate wind speeds of 4-7 m/s are favorable for imaging IWs by SAR, whereas very few IW signatures are observed when the wind speed is higher than 10 m/s and lower than 2 m/s. Many S sub m values are larger than 1 (positive signature) even when the angles between the wind direction and IW propagation direction (theta sub Wind-IW) are less than in the MAB, which does not agree with the result of da Silva et al. (2002). An advanced radar imaging model has been run for different wind conditions, radar look directions and IW amplitudes. The model results indicate that the proportion of S sub m values larger than 1, when theta sub Wind-IW < 90 degree , increases with IW amplitudes. In general, relating IW signature types mainly to the wind direction is an oversimplification without considering other factors such as look directions and IW amplitudes. An IW interaction pattern has been studied on the basis of two sequential images from ERS2 and ENVISAT with a time lag of 28 minutes and temperature and current measurements from moorings. Phase velocities of the pattern can be derived by two-dimensional cross correlation of two images or in-situ measurements. In this pattern, the IW packet with a larger amplitude shifts less while the one with a smaller amplitude shifts more due to the interaction. The strong intensity in the interaction zone implies an amplitude increase. The intensity changes in the same IW packet after the interaction implies the energy exchange. All the characteristics agree well with the dynamics of the two-soliton pattern with a negative phase shift, according to Peterson and van Groesen (2000).

Full textAbstract:
Cluster analyses of seasonal (spring and fall) National Marine Fisheries Service Groundfish Survey bottom trawl catches on the Middle Atlantic Bight continental shelf revealed consistent species associations and faunal zones over a nine year period during. Boundaries between faunal zones tended to follow isotherms on the inner portions of the shelf and isobaths along the outer shelf. During the late winter/early spring, four faunal zones were identified: a northern inner and middle shelf zone extending from Cape Cod southward to about Delaware Bay, a northern middle and outer shelf zone offshore of the first zone, a southern middle and outer shelf zone, and a fourth zone on the shelf break and upper slope. The southern inner shelf was a transition zone between the first and third zones. Five species groups were identified: a small cryophilic group restricted to the first zone, a cold-water boreal group found in the first two zones, a ubiquitous boreal/resident group containing the major dominants, a warm-temperate group confined to the warmer southern and outer shelf waters, and a group of slope residents confined to the deepest zone. During the fall, five faunal zones were identified: a southern inner and middle shelf zone, a northern inner shelf zone, a northern mid-shelf zone, an outer shelf zone and a shelf break/upper slope zone. The five species associations recognized were largely analogous to those in the spring, with the following exceptions: the cryophilic group was absent, the ubiquitous group contained mixed boreal and warm-temperate elements, and a second outer shelf group was recognized. The most notable change in the distribution of groups from the spring was a general northward shift in the distributions of the boreal species and a sharply defined inshore movement of the warm temperate group. Analyses of a single summer cruise showed patterns of distribution intermediate to those seen during the spring and fall. Absolute abundances, both of individual species and the total fish community, were highly variable between areas, seasons and years. Species diversity and its components appear to be of little utility in describing the fish communities of the open continental shelves.

Full textAbstract:
The structure of surf-zone fish communities at Cassino (western South Atlantic, WSA) and the Chesapeake Bight (western North Atlantic, WNA) is described using historical beach seine data, to examine similarities between geographically isolated fish communities. Numerical classification, ANCOVA, Shanon-Wiener diversity and its components, and species rarefaction are used to describe fish community structure: (a) within habitat (Cassino); (b) within region (Chesapeake Bight); (c) within the western Atlantic (comparison between Cassino and the Chesapeake Bight). The surf-zone fish community at Cassino had a low diversity and was dominated by a few species. Seasonal periods identified by cluster analysis correlated well with seasonal environmental changes. The seasonal occurrence, abundance and diversity of fish species reflected recruitment patterns of juveniles, and seasonal variation in the marine and estuarine circulation patterns. Fish species associations usually fitted into three broad categories: year-round surf-zone residents; (b) spring to fall, estuarine related, pelagic planktivores or shallow water omnivores; (c) summer to fall coastal marine occasionals. Faunal similarity between Cassino and other selected locations of the WSA, decreased towards lower latitudes due to faunal replacements. In the Chesapeake Bight community structure was determined by differences between the two sampled localities. The community at Sandbridge was characterized by estuarine related species associated with the Chesapeake Bay. Sub-tropical coastal marine species at Cape Hatteras indicated influence of Gulf Stream waters. The seasonal species occurrence, abundance and diversity was determined by an enhanced seasonal migration along the coast, juvenile recruitment, and the thermal regime of the Chesapeake Bight. Ubiquitous surf-zone residents were replaced by a wintering group in the colder months. The diversity of estuarine related species at Sandbridge indicated that locally the surf-zone acted as a peripheral habitat for those species. Faunal similarities between the Chesapeake Bight and other WNA localities decreased both northward and southward due to faunal replacements. Similarities between surf-zone fish communities within the western Atlantic (Cassino x Chesapeake Bight) were correlated with the temperature range and habitat structure.

Full textAbstract:
In 2015, the COP21 creates a new hybrid mode of multilateral governance, which aims to make the action of non-states actors a bridge between the political commitments and the government’s actions. The business world is one of these actors with ambitious new roles to implement the Paris Agreements and its NDCs. Yet it seems that nobody has yet questioned whether companies can also act as leaders at their level or at least help their country/organisation to take the lead. To understand how business perceived their roles in the governance landscape post Paris-Agreement, several questions were asked to see what kind of leadership themselves were looking for. Who are the designated leaders for business when it comes to climate leadership? How have them evolved ? Why are they recognized as such? And what is the role of business in delivering Parties' NDCs in the post Paris-Agreement area? Thanks to a unique data collection of questionnaires distributed on COP22 to 25, it appeared that European leadership is not only the most consistent but also the most recognised, although the other EU partners in the BIG3 are far from demeriting. As the issue is particularly political, it was found that the recognition of leadership is not only due to certain leaders but also to many laws, which create and restrict many opportunities for business. The history and culture of the countries concerned also provided many answers. Finally, it seemed unanimous that a cooperative work between governments and business would allow a better and faster reach of both NDCs and SDGs.

Full textAbstract:
Passive acoustic data have been collected using HARPs (High-frequency Acoustic Recording Packages) and were used to assess (1) the seasonality of blue whale D calls in the Southern California Bight, (2) their interannual abundance during 2007-2012 and (3) their diel variation. This goal has been achieved running the GPL (Generalized Power-Law) automated detector. (1) Blue whale D calls were detected in the Southern California Bight from May through November with a peak in July, even though few detections were from December to April as well. A key predictor for blue whale distribution and movement in the California Current region has been identified with zooplankton aggregations, paying a particular attention to those euphausiid species, such as E. pacifica and T. spinifera, which are blue whale favorite krill. The Southern California Bight experiences seasonal upwelling, resulting in an increase of productivity and prey availability. The summer and early fall have been marked as the most favorable periods. This supports the presence of blue whales in the area at that time, supposing these marine mammals exploit the region as a feeding ground. (2) As to the interannual abundance during 2007-2012, I found a large variability. I observed a great increase of vocalizations in 2007 and 2010, whereas a decrease was shown in the other years, which is well marked in 2009. It is my belief that these fluctuations in abundance of D calls detections through the deployed period are due to the alternation of El Nino and La Nina events, which occurred in those years. (3) The assessment of the daily timing of D calls production shows that D calls are more abundant during the day than during the night with a peak at 12:00 and 13:00. Assuming that D calling is associated with feeding, the daily pattern of D calls may be linked to the prey availability. E. pacifica and T. spinifera are among those species of krill which undertake daily vertical migrations, remaining at depth during the day and slowly coming up towards the surface at night. Because of some anatomical arrangements, these euphausiids are very sensitive to the light. Given that we believe D calls have a social function, I hypothesize that blue whales may recognize the hours at the highest solar incidence as the best moment of the day in terms of prey availability, exploiting this time window to advert their conspecifics.

Full textAbstract:
A total of 12,323 summer flounder were tagged and released in Chesapeake Bay, the coastal waters off Virginia Beach, and the Eastern Shore during 1987-89. Excluding immediate recaptures, a total of 675 were recaptured for an overall return rate of 5.5%. Returns from the commercial fishery (56.2%) outnumbered those from the recreational fishery (35.7%). The majority of returns (47.1%) came from either Virginia waters or areas to the south, while only 12.8% were from areas to the north of Virginia. offshore returns accounted for 8.5% of the total. Returns with insufficient location data made up the remaining 31.5%. of the returns with sufficient recapture location data, 69% were from Virginia waters or areas to the south. Differences in length at tagging were noted between these groups with smaller fish accounting for a larger proportion of the returns from northern waters. The returns from Virginia waters and areas to the south were more representative of the entire size range of fish tagged. No behavioral differences were noted between tagged and untagged summer flounder held in the laboratory. No tag losses were noted in fish held over the course of one year. Scales were used to age summer flounder and were found to be adequate for ages 0-3, older fish were more difficult to age with scales. Percent agreement between scale and otolith determined ages (n = 170) was 100% for ages 0-5. Length frequencies of summer flounder were used to validate scale determined ages during 1987-89. Prominent modes in length frequencies represented ages 0-2, afterwards, differential growth between the sexes obscured the modes. Marginal increment analysis proved that the marks formed on scales were annular for ages 1-4 and that annulus formation occurred in May-June, at sizes ranging from 179-367 mm TL. Overall mean backcalculated length and the mean observed length in May for age-1 fish were 262 vs 265.4 mm. Mean backcalculated lengths for males were 249, 337, 393, and 455 mm TL for ages 1-4. Mean backcalculated lengths for females were 273, 379, 470, and 550 mm TL for ages 1-4. Backcalculated lengths at ages 1-7 for the pooled sexes were 262, 377, 473, 546, 600, 655, and 696 mm TL. Length-weight relations were calculated by sex for 2,172 fish. Overall sex ratio was 1:1.32, males to females. The sex ratio was approximately 1:1 for length groups up to 360 mm TL. Females outnumbered males at sizes greater than 360 mm TL. Male summer flounder reached 50% maturity at 261-270 mm TL, while females attained 50% maturity at 361-370 mm TL. Overall catch per unit effort decreased from 1.65 fish caught per minute to 0.4 from 1987 to 1989. Instantaneous rates of mortality for summer flounder caught in Chesapeake Bay and coastal waters ranged from 0.964 in 1988, to 1.655 in 1987. Instantaneous rates of mortality for summer flounder caught at Wachapreague ranged from 0.844 in 1989, to 3.608 in 1987.

Full textAbstract:
The Brazil Current (BC) is possibly one of the least studied western boundary currents (WBCs) in the world ocean. Its unique vertical structure makes this a different WBC in terms of velocity and transport. Although significant progress has been made over the last decade, the BC system variability within the Santos Bight (SB, 23°S-28°S) is very poorly understood despite its strategic role for Brazil in terms of energy. The BC thickens and changes its vertical structure and dynamical modal composition as it crosses the SB. As it enters the bight by trying to contour Cape Frio (Cf, 23°S), the BC is about 500 m deep. As the current leaves the bight south of Cape Santa Marta (CSM, 28°S) it is 1300 m. These differences in thickness and accompanying velocity vertical shear are due to the impinging branch of the intermediate South Equatorial Current (SEC) generating the so called Santos Bifurcation (SBi). We here investigate the subinertial variability of the BC system within the SB primarily using satellite altimetry data and some traditional spectral analysis techniques. We also analyzed quasi-synoptic observations of an oceanographic cruise, which was part of the IOUSP-PETROBRAS CERES Experiment. We identified that there are different phenomena occurring to the north and to the south of the bifurcation and this might be caused by the SBi feature itself and/or the consequential change in the BC vertical structure downstream. North of the SBi, we detected oscillations with period of 92 days and a wavelength of 490 km and which represent about a fifth of the BC variability at 25°S. The 92-day oscillations are nonlinear vorticity waves, which are originated to the east of 35°W and propagate zonally towards the BC axis. These waves then perturb the current exciting oscillatory motions of the same period and which propagate downstream. South of the SBi axis (~28°S), we identified two different maxima in the ω - κ spectrum. They correspond to oscillations with periods (wavelengths) of 68 and 148 days (397 km and 790 km). The longer wave is also a baroclinic first-mode nonlinear vorticity waves propagating with westward phase speed of the nondispersive planetary Rossby waves of same period. They are originated in the ocean interior and we were able to track its signal as far as 5°W. The 68-day waves has its existence limited to vicinities of the BC. Phase speeds have approximately the BC axis orientation and they can only be clearly detected between ~27°S and ~32°S. This propagating signal accounts with a variance of ~21% on the BC axis. Quasi-synoptic observations allowed the mapping of a anticyclone and a cyclone of such waves. They seem to have modal composition very similar to the BC itself, which might provide additional evidence of local origin.A Corrente do Brasil (CB) é provavelmente a Corrente de Contorno Oeste (CCO) menos estudada dos oceanos mundiais. A sua estrutura vertical única es faz dela uma CCO diferente em termos de velocidade e transporte. Apesar dos avanços significativos na última década, a variabilidade da CB na Bacia de Santos (BS, 23°S-28°S) ainda é pouco conhecida, apesar do papel estratégico da região na matriz energética brasileira. A CB se espessa mudando a sua estrutura vertical e muda sua estrutura dinâmica no domínio da BS. Na região de Cabo Frio (23°S) a corrente tem cerca de 500 m de profundidade. Ao sair da BS na região do Cabo de Santa Marta (28°S) a corrente se estende até cerca de 1300 m. Estas variações na espessura da corrente e consequente diferença no cisalhamento vertical de velocidade ocorrem devido à presença da Corrente Sul Equatorial em nível intermediário na região gerando a Bifurcação de Santos (BiS). Neste trabalho investigamos a variabilidade subinercial da CB na Bacia de Santos usando primeiramente dado alimétrico e um conjunto de análise espectral. Foram depois estudados fenômenos geradores dessa variabilidade com dados quasi-sinóticos do um cruzeiro oceanográfico CERES V do conjunto IOUSP-PETROBRAS. Foram identificados fenômenos diferentes no norte e sul da Bifurcação de Santos e esta diferença é provavelmente devido à presença da bifurcação ou à mudança que esta causa na estrutura da CB. Ao norte da BiS foi identificada uma oscilação com período de 92 dias e comprimento de onda de 490 km explicando um quinto da variabilidade da CB em 25°S. A oscilação de 92 dias está relacionada com ondas de vorticidade não lineares originadas a leste da corrente em ~35°W e se propagam zonalmente até ao eixo da corrente. Estas ondas perturbam a corrente originando oscilações com mesmo período e que propagam ao longo do eixo da corrente. Ao sul da BiS (~27°S) foram identificados dois máximos no espectro κ - ω. Os máximos correspondem a oscilações com período (comprimento de onda) de 68 e 148 dias (397 e 790 km). A onda com maior comprimento de onda é também uma onda de vorticidade de primeiro modo baroclínico não linear propagando para oeste com velocidade de fase de ondas de Rossby não dispersivas. Estas ondas são originadas no interior da bacia oceânica e seu sinal foi identificado chegando até 5°W. A onda de 68 dias existe apenas no domínio da CB. Esta onda propaga fase num eixo aproximadamente paralelo à CB e são detadas de forma clara apenas entre ~27°S e ~32°S. Esta onda explica uma variância da CB de ~21% ao longo do seu eixo. Observações quasi-sinóticas permitiram mapear um anticiclone e um ciclone associado a essa onda. Os vórtices aparentam uma estrutura modal muito semelhante à da corrente.
