Abstract (sommario):

O objetivo deste estudo foi analisar, através de índices climáticos, a variabilidade da precipitação na região Nordeste do Brasil. Para tanto foram utilizados dados em ponto de grade para gerar o índice de precipitação, bem como dados da National Oceanic Atmospheric Administration (NOAA) para gerar os índices de temperatura do oceano Pacífico (setor EN3.4) e do oceano Atlântico tropical norte e sul. O período de análise foi de 1970 a 2012. Com base nesses índices foram realizadas correlações lineares de Pearson, entre o oceano Pacífico e o Atlântico tropical norte e o oceano tropical sul, na costa do Brasil. Anomalias de precipitação também foram calculadas para alguns anos de ocorrência do evento El Niño, denotando expressiva variabilidade de um evento para outro. De maneira geral, as correlações entre os índices envolvendo os referidos oceanos foram positivas e expressivas, o que permite considerar a influência dos oceanos na dinâmica das chuvas na área de estudo. A importância do Atlântico sul é mais nítida quando os índices de temperatura da superfície do mar apresentaram o mesmo sinal, tanto no Pacífico quanto no Atlântico, o que implica em correlações mais marcadas.Palavras-chave: Forçante climática, El Niño 3.4, Nordeste do Brasil, Atlântico tropical, Anomalias da precipitação.Analysis of Surface Temperature Indices of the Intertropical Zones of the Pacific and Atlantic Oceans associated with rainfall in Northeastern Brazil ABSTRACTThe objective of this study was to analyze, through climatic indices, the variability of precipitation in the Northeast region of Brazil. For that purpose, grid point data were used characterize the precipitation behaviour, as well as data from the National Oceanic Atmospheric Administration (NOAA) to determine the temperature of the Pacific Ocean (sector EN3.4) and the tropical North and South Atlantic Ocean. Based on these data, correlations were made, which are characterized as marked, between the dynamics of the Pacific Ocean and the dynamics of the tropical North and South Atlantic, directly influencing the precipitation regime in Northeast Brazil. Precipitation anomalies were also calculated for some years of the El Niño event, showing significant variability from one event to another. In general, the correlations between the indexes involving the referred oceans were positive and expressive, which allows considering the influence of the oceans on the dynamics of rainfall in the study area. The importance of the South Atlantic is clearer when the sea surface temperature indices show the same sign, both in the Pacific and in the Atlantic, which implies more marked correlations.Keywords: Climate forcing, El Niño 3.4, Northeast Brazil, Tropical Atlantic, Precipitation anomalies.

Abstract (sommario):

Context. Oceanic tides are a major source of tidal dissipation. They drive the evolution of planetary systems and the rotational dynamics of planets. However, two-dimensional (2D) models commonly used for the Earth cannot be applied to extrasolar telluric planets hosting potentially deep oceans because they ignore the three-dimensional (3D) effects related to the ocean’s vertical structure. Aims. Our goal is to investigate, in a consistant way, the importance of the contribution of internal gravity waves in the oceanic tidal response and to propose a modelling that allows one to treat a wide range of cases from shallow to deep oceans. Methods. A 3D ab initio model is developed to study the dynamics of a global planetary ocean. This model takes into account compressibility, stratification, and sphericity terms, which are usually ignored in 2D approaches. An analytic solution is computed and used to study the dependence of the tidal response on the tidal frequency and on the ocean depth and stratification. Results. In the 2D asymptotic limit, we recover the frequency-resonant behaviour due to surface inertial-gravity waves identified by early studies. As the ocean depth and Brunt–Väisälä frequency increase, the contribution of internal gravity waves grows in importance and the tidal response becomes 3D. In the case of deep oceans, the stable stratification induces resonances that can increase the tidal dissipation rate by several orders of magnitude. It is thus able to significantly affect the evolution time scale of the planetary rotation.

Abstract (sommario):

Abstract A common term in the continental and oceanic components of the global water cycle is freshwater discharge to the oceans. Many estimates of the annual average global discharge have been made over the past 100 yr with a surprisingly wide range. As more observations have become available and continental-scale land surface model simulations of runoff have improved, these past estimates are cast in a somewhat different light. In this paper, a combination of observations from 839 river gauging stations near the outlets of large river basins is used in combination with simulated runoff fields from two implementations of the Variable Infiltration Capacity land surface model to estimate continental runoff into the world’s oceans from 1950 to 2008. The gauges used account for ~58% of continental areas draining to the ocean worldwide, excluding Greenland and Antarctica. This study estimates that flows to the world’s oceans globally are 44 200 (±2660) km3 yr−1 (9% from Africa, 37% from Eurasia, 30% from South America, 16% from North America, and 8% from Australia–Oceania). These estimates are generally higher than previous estimates, with the largest differences in South America and Australia–Oceania. Given that roughly 42% of ocean-draining continental areas are ungauged, it is not surprising that estimates are sensitive to the land surface and hydrologic model (LSM) used, even with a correction applied to adjust for model bias. The results show that more and better in situ streamflow measurements would be most useful in reducing uncertainties, in particular in the southern tip of South America, the islands of Oceania, and central Africa.

Abstract (sommario):

The ongoing conceptualisation of oceans and the hydrosphere by Peters and Steinberg is to be welcomed. They continue to challenge geography’s historical tendency to focus on and from terrestrial spaces, exploring how oceans exceed their material, discursive and imagined boundaries along with their liquid form. This short commentary responds specifically to their assertion that ‘The ocean is fish’. Using the example of Atlantic salmon, it questions the directionality at the heart of Peters and Steinberg’s paper. It focuses particularly on the complex spatialities of salmonid life, and the ability of salmon to blur aquatic boundaries. The commentary argues that if oceans exceed, they are also exceeded, whether through the extra-planetary forces that guide salmonid migration and affect tides, or the inward flows of water from rivers. It ends by questioning the space given to non-human life in the more-than-wet ontology, asking how such actants might be implicated in oceanic excess, particularly when the ocean’s intrinsic voluminous excess renders them beyond human awareness or understanding.

Abstract (sommario):

To evaluate the amount of awareness and quality of knowledge about ocean life the average American possesses 100 men and 100 women were asked what they knew about the importance of the oceans, their attitudes toward protection of marine life and oceanic ecology, and their sources of information regarding oceans. 98% believed that oceans are necessary for human survival and 92% believed that marine life was essential to the over-all ecology. 89% believed that dumping and toxic pollution almost irreparably harm marine life and that such practices must be stopped. 48% obtained their information about the oceans from formal educational programs and 95% from popular movies and documentary video programs. These data indicate that adults are quite aware of the continuing problems which threaten the survival of ocean life, although few have any suggestions about solving such problems.

Abstract (sommario):

In this article we examine how Pacific Island Countries (pics) successfully championed a stand-alone Ocean Sustainable Development Goal (sdg) goal at the United Nations (un). We analyse how the un Post-2015 development process provided pics with a unique opportunity to use their experience with collective diplomacy and regional oceans governance to propose this international goal. In this article we establish how pics’ national and regional quest to strengthen their sovereign rights over marine resources motivated their diplomatic efforts for an Ocean sdg. The campaign was a significant political achievement, positioning these Large Ocean Island States (lois) as global ocean guardians. We critically evaluate the effectiveness of the pics’ diplomatic campaign to secure an international commitment for an Ocean sdg. The pics’ advocacy for Goal 14 under Agenda 2030 has enhanced their political effectiveness in the un by improving their recognition by other States as leaders in oceans governance. We suggest their Ocean sdg campaign forms part of a distinct and continuing brand of oceans diplomacy from Oceania.

Abstract (sommario):

Over the past twenty years, Black Atlantic Afrofuturism has been the dominant theoretical frame for thinking about the significance of Drexciya’s aquatically themed techno music and mythology. Yet there have been few analyses of Drexciya from the perspective of ecology, of the ocean as a marine environment. Through a semiotic analysis of Drexciya’s 1993 EP Bubble Metropolis, this paper moves the discussion of Drexciya in the direction of ecocriticism and blue cultural studies, or more broadly, the blue humanities, in order to interpret the stories it tells about an imagined ocean. What do these stories mean? Why are these stories important now? Through the production and circulation of oceanic narratives that encourage listeners to imagine, wonder about, and groove to the ocean, Drexciya’s music and mythology can be understood as a form of “pre-emptive activism,” which designates indirect activist modes that inspire people to care about places, such as an ocean, that they take for granted or ignore. By imagining oceans full of sound, Drexciya fostered a tacit form of marine environmentalism in the 1990s. With oceanic ecosystems on the edge of collapse as a result of the climate emergency, all forms of marine activism, from the direct to the indirect, have gained a new sense of urgency. We need to listen to Drexciya now more than ever.

Abstract (sommario):

Abstract A characteristic feature of global warming is the land–sea contrast, with stronger warming over land than over oceans. Recent studies find that this land–sea contrast also exists in equilibrium global change scenarios, and it is caused by differences in the availability of surface moisture over land and oceans. In this study it is illustrated that this land–sea contrast exists also on interannual time scales and that the ocean–land interaction is strongly asymmetric. The land surface temperature is more sensitive to the oceans than the oceans are to the land surface temperature, which is related to the processes causing the land–sea contrast in global warming scenarios. It suggests that the ocean’s natural variability and change is leading to variability and change with enhanced magnitudes over the continents, causing much of the longer-time-scale (decadal) global-scale continental climate variability. Model simulations illustrate that continental warming due to anthropogenic forcing (e.g., the warming at the end of the last century or future climate change scenarios) is mostly (80%–90%) indirectly forced by the contemporaneous ocean warming, not directly by local radiative forcing.

Abstract (sommario):

The sea surface temperature is one of the main variables for analyzing the global climate, and with that, it is essential to know its behavior. Thus, the objective of this study is to understand the best temperature variability of the sea surface of the Atlantic and Pacific oceans, through information on the causes of its variability using Wavelet analysis, and also using the climatic trends of the TSM of the oceans. Sea surface temperature anomaly data obtained through the National Oceanic and Atmospheric Administration with period of 1955-2018, for the Atlantic and Pacific Oceans, divided into sectors and some statistical analyzes were used. Using the wavelet analysis method, it was possible to observe the phenomena El Niño South Oscillation, Atlantic Dipole, sunspots and Pacific Decadal Oscillation, acting on the studied time series; however, the Pacific Decadal Oscillation, which occurs in the Pacific Ocean, proved to be a phenomenon of dominant time scale in the Atlantic and Pacific Oceans. The Mann-Kendall trend test showed a linear increase in the sea surface temperature anomaly for the two studied Oceans, and in both, the South sector has a greater increase than the North sector. Climate trends indicate that the Pacific Ocean is warming more than the Atlantic Ocean. It is also possible to conclude that the Southern sector of the two Oceans is heating up more than the Northern sector. The signs of the limit ranges for the averages of the southern sectors demonstrate greater variability of the anomalies at the South Atlantic and South Pacific. The Northern sector was more similar to the general basin, both in the Atlantic and the Pacific, proving the importance of continental areas for warming the oceans. These results were strengthened with those found by box plots and frequency distribution. The warming of the Pacific was also reinforced in all statistics mad.

Abstract (sommario):

The ocean plays a key role in the climate of Earth, and it is therefore expected that any oceans present on an exoplanet would also be a crucial component of the climate system and hence have implications for the habitability of the planet. However, many planetary and oceanic properties cannot be assumed to be the same on an exoplanet as on Earth, and therefore the behaviour of the ocean cannot be assumed. Here, basic land configurations are explored and a single meridional barrier is used throughout the other experiments, as this is the simplest configuration of any substantial land mass. The effect of ocean salinity, at a level both higher and lower than on Earth, is explored for the first time and reversal of the Earth-like meridional overturning circulation is found. The proportionality between mean salinity and salinity gradients in the ocean is established. The impact of planetary rotation period is also investigated, and it is concluded that a longer rotation period results in a greater poleward ocean heat transport, with the additional novel conclusions of a shallower thermocline depth, increased horizontal ocean velocities, and stronger overturning circulation. Finally, existing ocean modelling of a tidally locked configuration is furthered by the addition of different land masses, the extent of the zonal circulation and magnitude of the zonal heat transport is found to have significant dependence on the location of a meridional barrier in the ocean, with resulting dark side mean temperatures varying by over 7 ̋C. The modelling presented here highlights the importance of the consideration of the ocean in exoplanetary climate studies, and its role in planetary habitability.

The strategic concept of "blue oceans" is currently undoubtedly one of the most interesting and most often talked strategic concepts. The thesis is therefore deals with the development of this strategic concept at the time and on the basis of previous papers of the authors in which were introduced tools and frameworks that later became part of the blue ocean strategy concept. The thesis also deals with other publications that the idea of the concept uses in own frames or in some way continues to build upon it. Further a description of the whole strategic concept is presented with each of analytical framework and tool with emphasis on additional context and findings of the section on the recent development of the concept. A key part of the thesis is the application of the concept to the three services - Knihovnička.cz Prezi and the Steam and evavulation of these tools with emphasis to the conclusions that have been made in the recent development of the strategic concept of "blue oceans" and its application.

Abstract (sommario):

Type I X-ray bursts are thermonuclear burning events which occur on the surface of accreting neutron stars. Burning begins in a localised spot in the star’s ocean layer before spreading across the entire surface. By gaining a better understanding of X-ray bursts, tighter limits can be determined for other neutron star properties such as the mass, radius, spin frequency and magnetic field. The ocean environment is very extreme, involving much higher pressure, temperature and magnetic field strength compared to the conditions typically found in terrestrial systems. We shall be looking at the effects of the strong gravitational field, modelling the ocean using general relativistic hydrodynamics. The physics of X-ray bursts acts over a wide range of scales, which introduces a number of challenges when modelling them. In this work, we use the multiscale approach to couple together multiple physical models in order to best capture the physics across these various scales. On the smallest scales, the physics is dominated by turbulent burning. The speed of propagation of the burning front is much slower than the acoustic speed, making it difficult to model this with conventional numerical schemes. We therefore instead use the low Mach number approximation, which we have derived and implemented for the relativistic fluid equations based on the existing approach developed for the Newtonian case. On larger scales, the burning front can be thought of as a discontinuity. To model this, we investigate the reactive Riemann problem for relativistic deflagrations and detonations and develop a numerical solver. The large scale propagation of the burning front is believed to be dominated by the Coriolis force. To capture this behaviour, we have derived and implemented a model for the relativistic form of the shallow water equations. Finally, we construct a hybrid scheme to combine the best features of these approximations, extending existing adaptive mesh refinement techniques to include different physical models at different scales.

Abstract (sommario):

A number of previous studies have identified considerable mass dependent variations in the Cd isotope compositions of both terrestrial and extraterrestrial samples. On Earth, stable isotope effects for Cd are particularly prominent in the oceans, and the largest natural terrestrial Cd isotope fractionations of about 4‰ have been reported for Cd-depleted surface seawater. These effects have generally been attributed to reflect isotope fractionation of Cd that occurs during biological uptake and utilization of dissolved seawater Cd. This finding confirms studies, which identified Cd as an essential marine micronutrient. This was first inferred from the phosphate-like distribution of the metal in the oceans and more recently demonstrated by work, which confirmed that Cd can act as catalytic metal ion in carbonic anhydrase, an enzyme which plays a central role in inorganic carbon acquisition of phytoplankton in the oceans. The marine Cd isotope fractionations are thus of interest, as they can be used to study the cycling of the micronutrient Cd as well as its impact on ocean productivity and the global carbon cycle. As part of this PhD project, I have developed a new procedure for Cd isotope analyses of seawater, which is suitable for samples as large as 20 L and Cd concentrations as low as 1 pmol/L. The procedure involves use of a 111Cd-113Cd double spike, co-precipitation of Cd from seawater with Al(OH)3 Cd purification by column chromatography, and subsequent isotope analysis by MC-ICP-MS (multiple collector inductively coupled plasma mass spectrometry). The methodology can routinely provide є114=110Cd data with a precision of about ± 0:5є (2sd) when at least 20-30 ng of natural Cd are available for analysis. However, even seawater samples with Cd contents of only 1-3 ng can be analysed with a reproducibility of about ±3 to ± 5є. The new methodology was applied to investigate Cd isotope variations in about 150 seawater samples from the North Atlantic Ocean, the Southern Ocean HNLC (high nutrient low chlorophyll) region, and the Peruvian oxygen minimum zone in the Eastern Pacific Ocean. The samples exhibited variable but highly systematic Cd isotope variations that were comprehensively interpreted in the context of previously published oceanographic and biogeochemical data.

Abstract (sommario):

As the Arctic sea ice extent shrinks, it becomes feasible to navigate through the Arctic Ocean. The Arctic routes shorten the marine transport between the American and Asian-European continents. To enable navigation planning, reliable wave forecasts in the ice covered area is highly demanded. However, as one component of the ocean wave models, the wave-ice interaction modelling is still under development. To obtain good wave forecasts, the effect of all ice types on wave propagation must be modeled correctly.

This dissertation contributes to the wave-ice interaction modelling for general sea ice-covered waters. For this purpose, the research questions addressed include investigating a theoretical model that assumes ice covers as a continuous layer of viscoelastic material. The derived dispersion relation contains two parameters associated with the equivalent viscoelastic properties of different ice types. Implementation of this model in an operational ocean wave model is a numerical problem to solve. Parameters in this viscoelastic model require data calibration. Inverse methods are developed using measurements from a recent field campaign to establish a relation among ice types and these theoretical parameters.

Three main questions of this study are answered as the following. 1) To understand the physical nature of ice-water layered system in the viscoelastic model. The wave characteristics are compared with those from developed theories of wave propagation in other layered systems. It concludes that the roots of the dispersion relation are identified as the flexural gravity, pressure, shear, evanescent and Rayleigh-Lamb waves. A wave mode swap phenomenon is also discussed. 2) To solve the numerical issues in applying the model in a global ocean wave model WAVEWATCH III^®. Strategies of determining the dominant wave mode and expediency of the numerical procedure are proposed. The updated ice source module for WAVEWATCH III^® performs better in accuracy, efficiency and robustness than its predecessor. 3) Inverse methods are applied to calibrate the model using data collected in the western Arctic Ocean, populated predominantly with pancake ice. The calibrated parameters can be used for wave forecasts in fields of the same ice type in the future. Furthermore, a combined laboratory and numerical study is conducted for wave propagating through an array of uniformed floes. The effective rigidity of the cover is explained by the change of elastic strain energy due to the free edges of each floe. An empirical relation is obtained for the effect rigidity in terms of the floe size and other length scales. This relation may be used to estimate the effective rigidity of an ice cover by in situ or remote sensing images. By answering the above questions, this dissertation contributes to the application of a viscoelastic model for wave hindcasts/forecasts in the whole ice-covered waters.

Abstract (sommario):

Oceans play a key role in climate regulation, transportation and recreation. Rising temperatures and ocean acidification significantly affect life in both water and on land. Over 3 billion people rely on the ocean for their livelihoods, with ocean industries making up 5% of the global GDP. Our goal is to focus on the relationship between marine science, technology and human interaction in order to address illegal fishing, marine pollution, international policies within developing nations. Through our presentation we will explore both positive and negative interactions between policy and science impacting our oceans. SDG Theme: SDG 14 – Life below water Type: Short talk (e.g. PowerPoint, Google Slides)

Abstract (sommario):

This deliverable reports about the successful completion of three group discussions on marine carbon dioxide removal (CDR) with laypersons in Germany. The 2-hour group discussions were held online. 5 participants discussed these three topics: (1) the environmental state of the oceans, (2) four selected marine CDR approaches, and (3) responsible research and innovation. The four approaches were ocean fertilization, ocean alkalinization via ocean liming and electrochemical weathering in desalination plants, artificial upwelling, and blue carbon management via kelp forests, mangroves and seagrass meadows.

Abstract (sommario):

Limiting global warming to 1.5°C requires a large-scale removal of carbon dioxide from the atmosphere. The oceans have been proposed as one possible storage option, however, not without environmental consequences. Adverse impacts on ecosystems are expected to increase in the amount of carbon stored. The question arises whether the removed carbon should be stored in a small area, e.g. a bay, or spread out across the oceans. We study this question in an analytic model with two types of ocean boxes, characterised by their carbon content. Storing a lot of carbon in the small box (a bay) may cause the local ecosystem to cross a tipping point, whereas spreading out in the large box (the rest of the ocean) may avoid this, while still causing ecosystem damages. The model gives rise to two different steady state solutions. A “destroy” steady state, where the tipping point in the small ocean box has been crossed, and a “diffuse” steady state without destruction. We analytically and numerically study the optimal amount of carbon stored, and the optimal distribution of carbon sequestration across the two boxes.

Abstract (sommario):

The coastal and open oceans represent a major, but yet unconstrained, sink for plastics. It is likely that plastic-biota interactions are a key driver for the fragmentation, aggregation, and vertical transport of plastic litter from surface waters to sedimentary sinks. Cruise SO279 conducted sampling to address core questions of microplastic distribution in the open ocean water column, biota, and sediments. Seven stations were sampled between the outer Bay of Biscay and the primary working area south of the Azores. Additional samples were collected from surface waters along the cruise track to link European coastal and shelf waters with the open ocean gyre. Microplastic samples coupled with geochemical tracer analyses will build a mechanistic understanding of MP transport and its biological impact reaching from coastal seas to the central gyre water column and sinks at the seabed. Furthermore, floating plastics were sampled for microbial community and genetic analyses to investigate potential enzymatic degradation pathways. Cruise SO279 served as the third cruise of a number of connected research cruises to build an understanding of the transport pathways of plastic and microplastic debris in the North Atlantic from the input through rivers and air across coastal seas into the accumulation spots in the North Atlantic gyre and the vertical export to its sink at the seabed. The cruise was an international effort as part of the JPI Oceans project HOTMIC (“HOrizontal and vertical oceanic distribution, Transport, and impact of MICroplastics”) and the BMBF funded project PLASTISEA (‘Harvesting the marine Plastisphere for novel cleaning concepts’), and formed a joint effort of HOTMIC and PLASTISEA researchers from a range of countries and institutes.
