Characterization of an Algicidal Agent Produced by the Bacterium Shewanella

We examined a biological control agent isolated from a bacteria species that may provide a mechanism for halting the growth of certain types of toxic dinoflagellate harmful algal blooms. We characterized the activity of the algicidal agent and its impact on dinoflagellate physiology. We also evaluated the effect of the ...

Characterization of Benthic Habitats and Contaminant Assessment in Arctic Lagoons and Estuaries

We conducted an environmental characterization of lagoons and estuaries in northwest Alaska prior to oil and gas development in the region. Our results will provide natural resource managers and residents in the area baseline information on the state of biological resources and contaminants in Arctic lagoons and estuaries in the ...

Characterization of Land-Based Sources of Pollution and Effects in the St. Thomas East End Reserves (STEER)

We assessed the condition of the St. Thomas East End Reserves, establishing a baseline from which we can evaluate the effectiveness of restoration activities. This is the first reserve-wide integrated ecological assessment that includes chemical contaminants in sediments, coral, fish, and conch; toxicity of sediments; nutrient levels; and sedimentation rates, ...

Characterization of Toxin Synthesis Pathways in Toxic Dinoflagellates

During the past 25 years, the abundance, range, and variety of harmful algal blooms (HABs) and their toxins have been increasing, impacting human and marine animal health through consumption of contaminated shellfish, finfish, and water or aerosol exposure. HAB dinoflagellate algae make some of the most potent toxins on Earth, ...

Characterizing and Mapping Essential Fish Habitats Affected by Human Activities off Puerto Rico

The purpose of this project was to collect, integrate and map available information on the features of essential fish habitats in protected and non-protected marine areas around the islands of Puerto Rico. The information obtained will help: 1) describe and select habitats for monitoring impacts of fishing and non-fishing activities, ...

Characterizing Benthic Habitats Around Saipan, CNMI to Support Marianas Campaign

In 2019, NOAA launched the Pacific Mapping Cooperative: Marianas Campaign to develop a plan to conduct much-needed mapping in the Marianas Archipelago. NCCOS was requested to generate contemporary, high-resolution shallow water benthic habitat maps for select areas off Saipan, which is the largest territory in the Commonwealth of the Northern ...

Characterizing Benthic Habitats in Haputo Ecological Reserve Area, Guam

In 2012, the US Naval Facilities Engineering Command (NAVFAC) Marianas developed an Integrated Natural Resource Management Plan (INRMP) for the Joint Region Marianas (JRM). The purpose of this plan is to mitigate impacts of the US Navy’s mission on submerged lands under their control and develop functioning, sustainable ecological communities ...

Characterizing Fish and Invertebrates of the Shallow Coral Reefs of the Flower Garden Banks National Marine Sanctuary

We characterized the coral and fish communities on the sanctuary’s shallow reefs based on data collected in 2006 and 2007. We focused on two management goals: 1) to develop a sampling design for monitoring benthic fish communities on the coral reefs; and 2) to obtain a spatial and quantitative biogeographic ...

Characterizing Recreational Shore-based Fishers and Fishing on St. Croix, U.S. Virgin Islands

The objective of our survey on St. Croix, U.S. Virgin Islands was to test an approach for collecting shore-based recreational fishing data, such as who fishes from shore, for how long, and what they catch. We were interested in understanding the spatial and temporal patterns of shore-based fishing, as well ...

Characterizing Submerged Lands around Navy Base Guam, CNMI

In 2012, the U.S. Naval Facilities Engineering Command (NAVFAC) Marianas developed a resource plan for the Commonwealth of the Northern Mariana Islands (CNMI). The purpose of this plan is to mitigate impacts of the U.S. Navy’s mission on submerged lands under their control. NAVFAC requested that NCCOS develop an updated ...

Chesapeake Bay Climate Sensitivity Assessment

The Chesapeake Bay is one of the largest estuaries in the world, economically valuable for its productive habitats, valuable fisheries, and recreational opportunities. However, it is clear that climate changes will influence this important coastal ecosystem. We are using the Chesapeake Bay National Estuarine Research Reserve System and historical data ...

Chesapeake Bay Vibrio Pathogen Forecast

We forecast where and when pathogens are most likely to be found in the Chesapeake Bay, based on the salinity and temperature of the water. Public health officials use our forecasts to target public safety messages and monitoring. When pathogens are present, cooking shellfish and washing open wounds after contact ...

Ciguatera Fish Poisoning: Identifying Toxic Species

Ciguatera fish poisoning (CFP) is the most common, non-bacterial, seafood illness. The condition is caused by toxins from the microalga Gambierdiscus, and can lead to diarrhea, paralysis, and, in worst cases, death. Currently, there is no easy method for measuring CFP toxins. We are evaluating screening methods for CFP cells, ...

Ciguatoxin Impacts on Foraging Behavior in Hawaiian Monk Seals

Hawaiian monk seals, which are critically endangered, inhabit the Papahānaumokuākea Marine National Monument and the Hawaiian Islands. For the first time we have identified the algal toxin ciguatoxin, the cause of ciguatera fish poisoning syndrome, in Hawaiian monk seals. We developed an experimental model using mice to determine the effect ...

Climate Change Impacts on Intertidal Zone Populations

The intertidal zone, which lies between the high and low tide marks on the shores of the world’s oceans, is a sensitive indicator of the effects of climate variability and climate change on marine species. We examined the effects of long-term temperature changes on the population biology of dominant species ...

Coastal Ecological Assessments and Indicator Development

We work in partnership with other federal agencies and coastal states to conduct assessments of ecological condition and potential stressor impacts throughout our Nation’s estuaries, coastal-ocean waters, and NOAA protected areas; carry out studies to determine environmental impacts of specific pollution events or natural disasters; and perform additional related research ...

Coastal Ecosystem Susceptibility to Nutrient Pollution

We studied the estuaries of the U.S. East Coast and Gulf of Mexico to determine which coastal areas are most vulnerable to changes in nutrient input. We modeled the environmental and economic impacts of land-use changes to understand the water flow (hydrology) and nutrient runoff in these areas. These models ...

Coastal Marine Mammal Stranding Assessments

We are studying stranded marine mammals to determine causes of death, anthropogenic sources of mortality, contaminant loads, diseases processes, and life history traits. We are sharing these assessments with resource managers, the public, and groups using potentially harmful chemical contaminants in the coastal zone. The health of coastal marine mammal ...

Coastal Water Quality Monitoring and Tool Development

We are researching the factors that drive bacterial pollution in estuarine waters (e.g., climate variability, wastewater management, and agricultural practices), and their potential as indicators of estuarine condition. Our research will support management of coastal resources through better understanding of how human practices and climate changes affect coastal condition in ...

Codevelopment of Modeling Tools to Manage Sediment for Sustainable and Resilient Coastal Lowland Habitat in Southern California

We will advance scientific, engineering, and policy perspectives on how sediment can be managed in coastal lowlands to reduce flood risk, bank instability, and erosion risk. We will evaluate sediment management practices for both average and extreme event conditions by investigating how varying tides, stream flow, and precipitation influence sediment, ...
