Abstract:
Marine mammals comprise a paraphyletic group of species whose current abundance and distribution has been greatly shaped by past environmental changes and anthropogenic impacts. This thesis describes molecular ecological approaches to answer questions regarding habitat requirements, genetic differentiation, and life-history trade-offs in three species of marine mammals.  The annual sea-ice dynamics of the Arctic may have large effects on the abundance and distribution of Arctic species such as the pagophilic ringed seal (Pusa hispida). Paper I describes and applies a simple molecular method for isolating and characterizing a relatively large set of single nucleotide polymorphisms (SNPs) in the ringed seal. These SNPs have been genotyped in a yet-to-be-analysed dataset which will form the basis in an assessment of the micro-evolutionary effects of annual sea-ice dynamics on ringed seal.  Current management efforts directed towards the North Atlantic fin whale (Balaenoptera physalus) are hampered by an unclear understanding of population structure. Paper II investigates the DNA basis for the high levels of genetic differentiation that have been reported in allozyme studies of the North Atlantic fin whale. We find that additional processes (at the organismal level) may have contributed to shaping the phenotype of the underlying allozyme variation. Telomeres may potentially serve as markers for determining the chronological and biological age of animals where other means of inference is difficult. Paper III describes the application and evaluation of four qPCR assays for telomere length estimation in humpback whales (Megaptera novaeangliae), finding that reliable telomere length estimates require extensive quality control. Paper IV applies the best performing qPCR assay to test whether telomeres may provide a method for genetic determination of chronological age in whales and concludes that the biological and experimental variation in telomere length estimates is too large to determine age with sufficient resolution. Finally, because telomere length and rate of telomere loss also may be affected by other cellular and organismal processes, such as resource allocation among self-maintenance mechanisms, growth and reproduction, Paper V describes the correlations between individual telomere length and rate of telomere loss, and sex, maturity status and female reproductive output. We found that the costs of reproduction in terms of telomere loss are higher in mature humpback whales than in juveniles; that reproductive costs are higher in males than females; and that differences among females tend to correlate with reproductive output.

Marine microbes play a fundamental role in driving ocean ecosystem dynamics and biogeochemistry. While their importance is global in scale, microbial processes unfold at the level of single cells and are intimately dependent on interactions between microorganisms, their neighbors, and the surrounding physical and chemical environment. Furthermore, traditional imaging techniques often provide frozen snapshots of the marine microbial world, yet microbial interactions are inherently dynamic, as for example in the case of motility, chemotaxis, and the encounter of microbes with viruses and animal hosts. These biological processes are frequently driven by physical mechanisms, and our understanding of them can benefit from a focus on the physical ecology of marine microbes. This is the approach pursued in this thesis, by directly applying dynamic imaging and microfluidics, which offer powerful new opportunities to study microbial processes in a time resolved manner and with exquisite environmental control. Through single-cell, live imaging of three fundamental marine microbial processes - motility, chemotaxis and viral adsorption - we demonstrate how capturing previously unseen biophysical processes in microbial ecology at their natural timescales can both shed light on unexplained mechanisms and provide robust quantifications of interaction rates. We first study a newly discovered nanoscale motility adaptation in the marine bacterium Vibrio alginolyticus using high-speed imaging. We found that marine bacteria can exploit a buckling instability of their flagellum to change direction during swimming, achieving the same functionality as multi-flagellated cells, but with the cost of synthesizing and operating only one flagellum. This finding not only reveals a new role of flexibility in prokaryotic flagella, but also highlights the exquisite motility adaptations of marine microbes to the resource-poor environment of the ocean. We then determine how this motility adaptation affects the cells' ability to climb chemical gradients ('chemotaxis'). We found that, counter- to current models, chemotaxis in V. alginolyticus is speed-dependent. Faster cells exhibited not only faster chemotactic migration, but also tighter accumulation around the resource peak. This result adds a new dimension to our understanding of bacterial chemotaxis pathways, by demonstrating that swimming speed can be an important and counter-intuitive control parameter in how marine microbes encounter and exploit chemical resources. Finally, we consider an encounter process that is motility-independent - that between a nonmotile host and a virus. Using the globally abundant marine cyanobacterium Prochlorococcus and a cyanobacterial virus ('cyanophage') as a model system, we directly imaged the encounter and adsorption dynamics of the virus and the host at the level of single cells, using dual-wavelength epifluorescent microscopy. By applying this non-invasive approach to quantify thousands of encounter events using automated image acquisition and analysis, we directly measured the rate at which viruses encounter and adsorb to hosts. We found that the probability of adsorption is considerably lower than was obtained with traditional, bulk measurement approaches, suggesting the need for a revision of viral infection dynamics in marine ecosystem models and opening the door for studies of microbial individuality in the context of viral infection. In summary, this thesis demonstrates that physical processes in microbial ecology, studied by means of new approaches including microfluidics and dynamic imaging at the single-cell scale, can contribute fundamental new insights into the ecology of marine microbes.

Abstract:
Seabirds have evolved within an open and dynamic environment, the ocean. As meso-top predators, seabirds are greatly influenced by the oceanographic conditions driving marine productivity, and therefore, distribution of their prey. Consequently, seabirds’ behaviour and, ultimately, life-history traits are greatly influenced, by the ever-changing oceanographic conditions. However, oceanographic conditions are currently changing at ever-increasing rates due to global warming and human harvest impacting marine ecosystems. Thus, seabirds have become particularly vulnerable to these changes. Accordingly, in this thesis, we investigated the ecological responses of seabirds, in terms of foraging and breeding performance, to the spatio-temporal variability of environmental conditions imposed by oceans and exacerbated by climate and human stressors. In particular, we (i) identified the climate and human stressors impacting the world’s ocean, (ii) investigated the actual scale at which seabirds interact with their environment, (iii) assessed how seabirds respond to oceanographic variability by changing their foraging and reproductive strategies and (iv) proposed an integrative tool for the design of marine reserves protecting seabirds and their environment. The objectives of this thesis were accomplished through advanced procedures in the fields of satellite remote sensing and animal tracking. Our results confirmed the unprecedented changes experienced by oceans in the last decades. However, we were able to provide deepest insights on the uneven distribution of climate and human driven environmental changes. When investigating the link between such environmental variability and seabirds’ behaviour, we found that dynamic processes as ocean currents were key factors determining the scale at which seabirds interact with their environment. Environmental features driving the spatiotemporal distribution of prey (e.g. sea surface temperature, chlorophyll-a, sea fronts and persistent areas of productivity) along with industrial fisheries played a fundamental role in determining the foraging distribution of seabirds. However, seabirds’ foraging strategies were largely constrained by limitations imposed by their central-place foraging behaviour and by dynamic factors such as prevalent winds, which influenced individual decision- making in heading directions when foraging. Intra and interspecific competition for resources also modulated foraging distributions, avoiding conspecifics or segregating foraging areas among sympatric species in appropriate stages. In general, we have provided a complete picture of environmental processes affecting seabirds. We argue that this information would be extremely useful for designing suitable management and conservation strategies. Thus, we finally proposed an adaptive framework for delimitation of more meaningful marine reserves that maximises conservation targets for seabirds, while accounting for human activities, environmental and biological factors largely driven seabird performance and, remarkably, the dynamism inherent to marine systems.

Gaining an understanding of the spatial ecology of marine turtles is essential for elucidating aspects of their life history ecology and for effective conservation management. This thesis presents a collection of chapters seeking to investigate the spatial ecology of this taxon. An array of technologies and methodologies are employed to ask both ecological and spatial management questions. Work focuses on foraging and thermal ecology, spatial appropriateness of Marine Protected Areas, movement models to describe habitat utilisation, analysis of data from sightings and strandings schemes and the use of a large synoptic fisheries dataset to describe fisheries patterns and putative risks to marine megavertebrates.

Abstract:
In this study phytoplankton viruses were investigated from a point of view of their genotypic richness, ecology and role in controlling two microalgae species: Emiliania huxleyi and Phaeocystis pouchetii. Host specificity determined for Emiliania huxleyi-virus (EhV) isolates revealed a highly variable host range suggesting a relation between virus specificity and genetic or phenotypic variations within E. huxleyi strains and EhVs. Subsequently the dynamics and genetic richness of Emiliania huxleyi and EhVs were monitored in mesocosm experiments and during the progression of a natural bloom in the sea. The results confirmed the role of virus infection in regulating the intraspecific succession of E. huxleyi in the ocean. Furthermore, they revealed significant differences in genotypic composition and dynamics among blooms. The mesocosm setup appeared to be a very robust experimental system, which allowed reproducibility. The most important factor determining the development of the blooms in the enclosures was the experimental manipulation (i.e. nutrient addition), whereas the effect of filling of the enclosures, delay in nutrient addition and position in the raft were of minor importance. Further laboratory experiments revealed differences in the genomic content of different EhVs. EhV isolates from the English Channel carry a putative phosphate permease gene (ehv117) while the only available EhV from a Norwegian fjord has replaced ehv117 with a putative endonuclease, suggesting different propagation strategies among closely related EhVs. Culture studies using one of the English Channel isolates and E. huxleyi CCMP 1516 showed that the lack of phosphate (P) reduced the growth rate of the host and inhibited the production of viral particles. Furthermore, P availability was shown to have an effect on the level of ehv117 expression. In addition, other mesocosm studies revealed that specific viruses (PpVs) play a significant role in the termination of induced Phaeocystis pouchetii blooms. However, the role of PpVs may be significant only for the flagellated stage of P. pouchetii. Phenotypic characteristics of PpVs isolated during these studies indicate that they are probably members of the Phycodnaviridae family.

Abstract:
Species distribution maps can provide important information to focus conservation efforts and enable spatial management of human activities. Two sympatric marine predators, grey seals (Halichoerus grypus) and harbour seals (Phoca vitulina), have overlapping ranges but contrasting population dynamics around the UK; whilst grey seals have generally increased, harbour seals have shown significant regional declines. A robust analytical methodology was developed to produce maps of grey and harbour seal usage estimates with corresponding uncertainty, and scales of spatial partitioning between the species were found. Throughout their range, both grey and harbour seals spend the majority of their time within 50 km of the coast. The scalability of the analytical approach was enhanced and environmental information to enable spatial predictions was included. The resultant maps have been applied to inform consent and licensing of marine renewable developments of wind farms and tidal turbines. For harbour seals around Orkney, northern Scotland, distance from haul out, proportion of sand in seabed sediment, and annual mean power were important predictors of space-use. Utilising seal usage maps, a framework was produced to allow shipping noise, an important marine anthropogenic stressor, to be explicitly incorporated into spatial planning. Potentially sensitive areas were identified through quantifying risk of exposure of shipping traffic to marine species. Individual noise exposure was predicted with associated uncertainty in an area with varying rates of co-occurrence. Across the UK, spatial overlap was highest within 50 km of the coast, close to seal haul outs. Areas identified with high risk of exposure included 11 Special Areas of Conservation (from a possible 25). Risk to harbour seal populations was highest, affecting half of all SACs associated with the species. For 20 of 28 animals in the acoustic exposure study, 95% CI for M-weighted cumulative Sound Exposure Levels had upper bounds above levels known to induce Temporary Threshold Shift. Predictions of broadband received sound pressure levels were underestimated on average by 0.7 dB re 1μPa (± 3.3). An analytical methodology was derived to allow ecological maps to be quantitatively compared. The Structural Similarity (SSIM) index was enhanced to incorporate uncertainty from underlying spatial models, and a software algorithm was developed to correct for internal edge effects so that loss of spatial information from the map comparison was limited. The application of the approach was demonstrated using a case study of sperm whales (Physeter macrocephalus, Linneaus 1758) in the Mediterranean Sea to identify areas where local-scale differences in space-use between groups and singleton whales occurred. SSIM is applicable to a broad range of spatial ecological data, providing a novel tool for map comparison.

Abstract:
Isoprene is an atmospheric trace gas whose emissions to the atmosphere are roughly equal to that of methane. It is highly reactive and has the potential to affect climate through a variety of interactions in the atmosphere, including the formation of ozone. In the marine environment alone, algae produce up to 11 Tg y-1 of isoprene. To date, little is known about its degradation by microbes in the marine environment. In this project, isoprene-degrading bacteria from a range of marine sites were characterised and Illumina sequencing was used to mine the genomes of isoprene-degrading strains related to Gordonia polyisoprenivorans and Mycobacterium hodleri, isolated from the Colne Estuary, Essex. From these genomes, we retrieved novel sequences encoding isoprene monooxygenase, previously identified in a terrestrial Rhodococcus species. This information allowed the design of specific PCR primer sets for the isoA gene, encoding the alpha subunit of isoprene monooxygenase, to retrieve isoprene-specific genes from environmental samples. The primers amplify isoA from a wide range of marine genera. A database of isoA sequences from extant isoprene degraders and isoA sequences retrieved by PCR from DNA from a variety of different marine environments was created. The data obtained demonstrated that isoprene monooxygenase genes are widespread in the marine environment. Other work focused on the physiology of isoprene-degrading bacteria, particularly the marine isolate Gordonia polyisoprenivorans. SDS-PAGE, oxygen electrode assays and RT-PCR were also used to investigate the regulation of soluble diiron centre monooxygenases in this organism, and showed that two separate, inducible monooxygenase enzyme systems exist in this organism and are responsible for the oxidation of isoprene and propane. DNA-Stable Isotope Probing revealed that members of the genera Rhodococcus, Mycobacterium, Gordonia and Microbacterium are active isoprene degraders in the Colne Estuary.

Abstract:
Protists are a taxonomic group of organisms world wild distributed with high abundance and biodiversity; their countless forms, sizes, and trophic activities constitute a continuum of species ranging from bacterial-sized cells for the smallest known species of chlorophytes to meters in length for the largest colonies of radiolaria. The enormous size range of protists, their many nutritional modes, and their rapid metabolic rates result in their pivotal ecological roles as primary producers and consumers at and near the base of marine food webs. Protists, in particular the heterotophic ones, are, with few metazoans larval stage, the major components of microzooplankton, on which this study focuses. Microzooplankton assemblage is described as a group of planktonic organisms in the size range of 10/20-200 µm; they are consumers of bacteria, cyanobacteria, other protists, viruses, and some metazoans. The quantitative importance of microzooplankton as consumers of primary production in the ocean has been recognized in the last decades; at the same time copepod predation on heterotrophic dinoflagellates and ciliates constitutes a trophic link more important than the phytoplankton–copepod link in many situations. Phagotrophic protists are the primary trophic link between minute cyanobacterial and bacterial production and higher organisms, a concept formalized more than 35 years ago in the microbial food web by Pomeroy (1974). In this study I want to provide more information on microzooplankton assemblages, describing the community composition and the role of this important component in different environments. I point out some of the factors influencing the distribution of these organisms with the aims to increase the current knowledge on microzooplankton and to contribute to the understanding of the phenomena that regulate the efficiency of the trophic web of the marine ecosystem. In the first chapter of the thesis entitled “Microzooplankton composition in the winter sea ice of the Weddell Sea” sympagic microzooplankton were studied during late winter in the northern Weddell Sea, for diversity, abundance and carbon biomass. In order to asses the role of microzooplanktonic component as food supply for the upper levels of the trophic web in this particular environment, the ice-cores were collected on an ice floe along three dive transects, and sea water was taken from under the ice through the central dive hole from which all transects were connected. The areal and vertical microzooplankton distributions in the ice and water were compared. They showed high abundance (max 1300 cells L-1) and biomass (max 28 µg C L-1) in the ice-cores, and were lower in the water, below sea ice (maxima, 19 cells L-1; 0.15 µg C L-1, respectively). The highest amounts were found in the lower 10 cm section of ice cores. The microzooplankton community within sea ice comprised mainly aloricate ciliates, foraminifers and micrometazoans. In winter, microzooplankton represent an important fraction of the sympagic community in the Antarctic sea ice. They can potentially control microalgal production and can contribute to particulate organic carbon concentrations when released into the water column due to ice melting in spring. Continued reduction of the sea ice might undermine these roles of microzooplankton, leading to reduction or completely loss in diversity, abundance and biomass of these sympagic protists. The second Chapter of this work focuses on the microbial community along the Ligurian coast in correspondence of two marine canyons. Community structures along the water column were studied using microscopic techniques, and their relationships with the environmental factors recorded along the canyons were investigated. The study considered pico-, nano- and micro-planktonic fractions, their abundances and

Abstract:
Modern accumulative and deflation forms of a coastal eolian relief on the sea coast of Kuronian and Vistula Spits are considered. It is established that on coastal barriers there are at the same time processes of accretion and degradation of a dune ridge and leaned against it foredune. Alternation of stable and erosive sites of a dune ridge is revealed. The last has destruction signs as with sea (wave erosion), and from the land side where the whirls of a wind stream creating numerous deflation basins in dune ridge have great value.

Abstract:
The problems of formation of the risk of a tsunami on the coast of the southern regions of the Far East Federal District. As the risk factors used features such as the relative position of the epicenters of tsunamigenic earthquakes and the coast, the underwater terrain coast, the degree of closeness of the studied bays, the presence or absence of wide beach and the first marine terraces, flowing into the characteristics of the studied coast estuaries. The factors subjected to expert estimates, taking into account their influence on the formation of the risk of a tsunami. The characteristics of the underwater topography, location in relation to the shores and bays of the epicenters of tsunamigenic earthquakes are estimated as zonal factors. Characteristics of marine terraces and river valleys are treated as local risk factors. For the first time for the coasts of Primorye and Khabarovsk area made of consequences of historical tsunamis: the presence of the devastation on the shores endured the tsunami waves from the open sea into the rivers and beaches ships, coast erosion, as well as descriptions of eyewitnesses. Characteristics of risk assessments are preceded by the WHO as areas of possible foci of tsunamigenic earthquakes, fault description and characteristics of buildings coasts. Risk assessment of the tsunami produces by the method proposed by G. Koff et al. The following characteristics was taken into account: the nature of the underwater coastal slope, exposure, banks in relation to the tsunami, the presence of the beach or I marine terrace, the presence of river valleys in the rear of the bay, the degree of openness of the bay. Overall, Nakhodka Bay and the Vostok Bay have the same performance tsunami -28,2 points. However, within these bays be provided with separate bays, with a higher risk assessment tsunami. Tsunami response coasts was made for these areas for the first time. Analysis of the materials allowed to identify the most tsunami zone, and to recommend the use of certain sections of the proposed development.

Abstract:
The Magnuson-Stevens Fishery Conservation and Management Reauthorization Act of 2006 mandat¬ed the research and management of the nation’s deep-sea coral resources through establishment of the National Oceanic and Atmospheric Administra¬tion’s Deep Sea Coral Research and Technology Program. The challenge for Alaska was daunting, where expansive, world-class fisheries often coincided with extraordinarily rich coral habitats for a high-latitude region. The first chal¬lenge was to inventory known locations of deep-sea corals. Many coral records and some museum collections existed from Alaska, but the taxonomy of cor¬als was little studied and field iden¬tification of corals was problematic. Formal bycatch programs and research activities in recent decades provided many more specimens for taxonomic study, but guides to species were largely incomplete, inaccurate, and outdated given the fast pace of species discovery in Alaska. We provide a comprehen¬sive, up-to-date guide, detailing 161 coral taxa identified from museum collections, primary literature, and video records. Each profile includes a description, images for each taxon, taxonomic history, biology, ecology, geographical distribution, and habitat, including depth distribution. Corals are found in the six regions of Alaska but the coral fauna of the Aleutian Islands is by far the most species rich. The state of taxonomy for some coral groups is ex¬cellent, while others require additional collections and more taxonomic work. Construction of this guide resulted in descriptions of several antipatharian species, published separately from this guide (Alternatipathes mirabilis, Bathypathes alaskensis, B. ptiloides, B. tiburonae, and Parantipathes pluma) and the scleractinian Flabellum (Flabel¬lum) oclairi Cairns, sp. nov. described herein. The guide provides informa¬tion for targeting new collections and identifying areas of high abundance and indicator species of vulnerable marine ecosystems. Stakeholders can now more adequately assess Alaska’s coral resources and risks from natural and anthropogenic stressors.

Harmful Algal Research & Response: A National Environmental Science Strategy (HARRNESS), 2024-2034. Woods Hole Oceanographic Institution, July 2024. http://dx.doi.org/10.1575/1912/69773.

Abstract:
Harmful and toxic algal blooms (HABs) are a well-established and severe threat to human health, economies, and marine and freshwater ecosystems on all coasts of the United States and its inland waters. HABs can comprise microalgae, cyanobacteria, and macroalgae (seaweeds). Their impacts, intensity, and geographic range have increased over past decades due to both human-induced and natural changes. In this report, HABs refers to both marine algal and freshwater cyanobacterial events. This Harmful Algal Research and Response: A National Environmental Science Strategy (HARRNESS) 2024-2034 plan builds on major accomplishments from past efforts, provides a state of the science update since the previous decadal HARRNESS plan (2005-2015), identifies key information gaps, and presents forward-thinking solutions. Major achievements on many fronts since the last HARRNESS are detailed in this report. They include improved understanding of bloom dynamics of large-scale regional HABs such as those of Pseudo-nitzschia on the west coast, Alexandrium on the east coast, Karenia brevis on the west Florida shelf, and Microcystis in Lake Erie, and advances in HAB sensor technology, allowing deployment on fixed and mobile platforms for long-term, continuous, remote HAB cell and toxin observations. New HABs and impacts have emerged. Freshwater HABs now occur in many inland waterways and their public health impacts through drinking and recreational water contamination have been characterized and new monitoring efforts have been initiated. Freshwater HAB toxins are finding their way into marine environments and contaminating seafood with unknown consequences. Blooms of Dinophysis spp., which can cause diarrhetic shellfish poisoning, have appeared around the US coast, but the causes are not understood. Similarly, blooms of fish- and shellfish-killing HABs are occurring in many regions and are especially threatening to aquaculture. The science, management, and decision-making necessary to manage the threat of HABs continue to involve a multidisciplinary group of scientists, managers, and agencies at various levels. The initial HARRNESS framework and the resulting National HAB Committee (NHC) have proven effective means to coordinate the academic, management, and stakeholder communities interested in national HAB issues and provide these entities with a collective voice, in part through this updated HARRNESS report. Congress and the Executive Branch have supported most of the advances achieved under HARRNESS (2005-2015) and continue to make HABs a priority. Congress has reauthorized the Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA) multiple times and continues to authorize the National Oceanic and Atmospheric Administration (NOAA) to fund and conduct HAB research and response, has given new roles to the US Environmental Protection Agency (EPA), and required an Interagency Working Group on HABHRCA (IWG HABHRCA). These efforts have been instrumental in coordinating HAB responses by federal and state agencies. Initial appropriations for NOAA HAB research and response decreased after 2005, but have increased substantially in the last few years, leading to many advances in HAB management in marine coastal and Great Lakes regions. With no specific funding for HABs, the US EPA has provided funding to states through existing laws, such as the Clean Water Act, Safe Drinking Water Act, and to members of the Great Lakes Interagency Task Force through the Great Lakes Restoration Initiative, to assist states and tribes in addressing issues related to HAB toxins and hypoxia. The US EPA has also worked towards fulfilling its mandate by providing tools and resources to states, territories, and local governments to help manage HABs and cyanotoxins, to effectively communicate the risks of cyanotoxins and to assist public water systems and water managers to manage HABs. These tools and resources include documents to assist with adopting recommended recreational criteria and/or swimming advisories, recommendations for public water systems to choose to apply health advisories for cyanotoxins, risk communication templates, videos and toolkits, monitoring guidance, and drinking water treatment optimization documents. Beginning in 2018, Congress has directed the U.S. Army Corps of Engineers (USACE) to develop a HAB research initiative to deliver scalable HAB prevention, detection, and management technologies intended to reduce the frequency and severity of HAB impacts to our Nation’s freshwater resources. Since the initial HARRNESS report, other federal agencies have become increasingly engaged in addressing HABs, a trend likely to continue given the evolution of regulations(e.g., US EPA drinking water health advisories and recreational water quality criteria for two cyanotoxins), and new understanding of risks associated with freshwater HABs. The NSF/NIEHS Oceans and Human Health Program has contributed substantially to our understanding of HABs. The US Geological Survey, Centers for Disease Control and Prevention, and the National Aeronautics Space Administration also contribute to HAB-related activities. In the preparation of this report, input was sought early on from a wide range of stakeholders, including participants from academia, industry, and government. The aim of this interdisciplinary effort is to provide summary information that will guide future research and management of HABs and inform policy development at the agency and congressional levels. As a result of this information gathering effort, four major HAB focus/programmatic areas were identified: 1) Observing systems, modeling, and forecasting; 2) Detection and ecological impacts, including genetics and bloom ecology; 3) HAB management including prevention, control, and mitigation, and 4) Human dimensions, including public health, socio-economics, outreach, and education. Focus groups were tasked with addressing a) our current understanding based on advances since HARRNESS 2005-2015, b) identification of critical information gaps and opportunities, and c) proposed recommendations for the future. The vision statement for HARRNESS 2024-2034 has been updated, as follows: “Over the next decade, in the context of global climate change projections, HARRNESS will define the magnitude, scope, and diversity of the HAB problem in US marine, brackish and freshwaters; strengthen coordination among agencies, stakeholders, and partners; advance the development of effective research and management solutions; and build resilience to address the broad range of US HAB problems impacting vulnerable communities and ecosystems.” This will guide federal, state, local and tribal agencies and nations, researchers, industry, and other organizations over the next decade to collectively work to address HAB problems in the United States.
