A Baseline Chemical Contaminants Study of Marine Sediments in Nu’uuli Pala Lagoon, American Samoa

We are assessing the scope and extent of land-based sources of chemical contaminants in the marine sediments of Nu’uuli Pala Lagoon in American Samoa. Currently, there are no contaminant data for the lagoon, and there are only limited data for one of the streams that empties into the lagoon. We ...

A Chemical Contaminant Characterization of Waters Surrounding Cocos Island, Guam, using Polyethylene Devices

We are assessing the scope and extent of land-based sources of chemical contaminants in the marine waters surrounding Cocos Island, Guam. Previous NCCOS studies identified a gap in polychlorinated biphenyls data, which this project will fill to better inform management decisions about the island and its marine waters. NOAA’s Coral ...

A Geospatial Assessment of U.S. Atlantic and Gulf of Mexico Essential Fish Habitat in Relation to Offshore Sand Features

Offshore sand resources, e.g., sand shoals, are increasingly being used for beach renourishment, barrier island restoration, and other uses to enhance resiliency of shorelines. However, the impact of sand dredging on fish and other marine resources is poorly understood. We are working with the Bureau of Ocean Energy Management and ...

A Management Tool to Reduce Sea Turtle Bycatch in the U.S. Atlantic Ocean and Gulf of Mexico Fisheries

Along with our partners, we developed a geographic information system (GIS) tool to help coastal managers work toward reducing the bycatch of sea turtles in U.S. fisheries in the Atlantic Ocean and Gulf of Mexico. The system factors in sea turtle distribution, commercial fishing activity, observed takes (bycatch) of sea ...

A Marine Biogeographic Assessment of the Northwestern Hawaiian Islands

We conducted a biogeographic assessment of the Northwestern Hawaiian Islands, the second largest marine protected area in the world. The effort was the most comprehensive view of the area’s oceanography, seafloor habitats, and the presence, distribution, and connectivity of the area’s marine resources. It was used to support protection measures ...

A Mechanism Based Intervention for Brevetoxin Induced Oxidative Stress

The Florida manatee inhabits environments in which blooms of the toxic dinoflagellate, Karenia brevis, frequently occur. K. brevis produces brevetoxins, that result in fish kills, contamination of shellfish, and respiratory effects. Evidence suggests that the toxins produced by these blooms can impact immune function in marine organisms. This project will ...

A Multidisciplinary, Integrative Approach to Valuing Ecosystem Services from Natural Infrastructure

We are estimating the economic value from natural and nature-based infrastructure investments to stabilize coastline. Using hazard risks along the U.S. Pacific Northwest coast, we are assigning a dollar value to ecosystem services lacking a market price. Specifically, we are applying three ecosystem service valuation methodologies (revealed preference hedonic modeling, ...

A Study of Gambierdiscus ‘Super Bugs’ and Ciguatoxin Fate in Coral Reef Food Webs

Ciguatera fish poisoning (CFP) is the most common algal-borne illness worldwide. It is a debilitating syndrome caused by consumption of fish contaminated with ciguatoxins (CTXs) produced by the dinoflagellate Gambierdiscus. Understanding of CTX in marine food web dynamics is poor, as is identification of the truly toxic Gambierdiscus species/strains (e.g., ...

A Synthesis of Chemical Contaminants Monitoring Data in Southeast and Southwest Alaska

Between 2007 and 2018, the National Park Service and its partners in association with NOAA’s National Mussel Watch Program collected bay mussel (Mytilus trossulus) tissue samples from Alaska's southeast and southwest coastal waters. The researchers analyzed the samples for a suite of chemical contaminants to create a baseline of contaminant ...

Acoustic Tracking of Fish Movements to Support Habitat Management

We are monitoring the movement and residence time of fish in several coastal ecosystems. Our objectives are to document habitat preferences of fish, the timing and scales of their mobility, and to establish how habitats are linked through fish movements. Results will help managers understand the effectiveness of marine protected area ...

Aggression is a Symptom of Domoic Acid Poisoning in California Sea Lions

To gain a better understanding of symptoms experienced by California sea lions caused by the toxin domoic acid, we are studying the relationship between aggression and seizure behavior in laboratory rats exposed to domoic acid. Our results have shown increased aggression can be a symptom of domoic acid poisoning whether ...

An Assessment of Chemical Contaminants in Sediment and Corals in Southwest Puerto Rico

We studied the coastal waters of southwest Puerto Rico to find out what kind and how much pollution (chemical contaminants) are in sediments and corals (Porites astreoides) and how that pollution affects the health of the coral reef. For the most part, concentrations of the pollutants analyzed were similar to ...

An Assessment of Fisheries Species to Inform Time-of-Year Restrictions for North Carolina and South Carolina

Environmental windows or moratoria are used by federal and state regulators in resource management to temporarily reduce adverse environmental impacts associated with coastal development. Seasonal restrictions on construction activities can protect migrations of fish, sensitive life stages of aquatic organisms, and threatened and endangered species. We reviewed the life history ...

An Early Warning System for Pseudo-nitzschia Harmful Algal Blooms on Pacific Northwest Outer-Coast Beaches

Blooms of some species of the diatom Pseudo-nitzschia produce a neurotoxin that accumulates in shellfish, which can cause illness and even death in humans who eat them. Shellfish managers monitor these toxins and close affected fisheries to protect public health, but these sudden closures can disrupt coastal economies. Using predictive ...

An Ecological Assessment to Support NOAA’s Choptank Complex Habitat Focus Area – Phase II

The Choptank watershed is an ecologically and economically valuable resource and designated Habitat Focus Area. We are collecting and synthesizing biological, chemical, and physical data to characterize the condition of the watershed and identify land use impacts on the environment. This project provides baseline information to assess management actions to ...

An Ecological Characterization of the Marine Resources of Vieques, Puerto Rico

We studied the coastal waters of Vieques, Puerto Rico, looking at fish and bottom-dwelling animals, contaminants in sediments and corals, and nutrient levels in surface waters. We also mapped the ocean floor surrounding the island. We confirmed the area was safe for the residents to return by determining that the ...

An Economic Analysis of Shipping Costs Related to Potential Measures to Manage the Co-Occurrence of Maritime Vessel Traffic and Whales in the Channel Islands Region

Through an analysis of shipping costs, we provided scientific guidance to the Channel Islands National Marine Sanctuary (CINMS) and other agencies, regarding the economic effects of potential management measures that balance commerce, conservation, and recreational uses within the Sanctuary. Why We Care The Channel Islands National Marine Sanctuary (CINMS) encompasses 1,110 square ...

An Integrated Assessment of Oil and Gas Release into the Marine Environment at the Former Taylor Energy MC20 Site

In 2004, the Taylor Energy Mississippi Canyon 20 (MC20) oil and gas drilling platform was toppled during Hurricane Ivan. Since the collapse of the drilling platform, the MC20 site has been associated with persistent plumes of oil and gas and surface oil slicks. At the request of the Department of ...

Analysis of Marine Ecological Information Gaps in National Parks

We compiled and analyzed biological and ecological data to identify information voids in support of the National Park Service’s (NPS) management of marine resources within its jurisdiction. The biological and ecological information included fish surveys, sea floor habitat maps, water quality monitoring, and coastal development tracking. The database also identified ...

Analysis of the Distribution and Abundance of Groundfishes to Support the California Current Integrated Ecosystem Assessment

We developed maps of occurrence and relative abundance for selected groundfish off the coasts of California, Oregon, and Washington, within the California Current Large Marine Ecosystem (CCLME). Our project supports NOAA’s Integrated Ecosystem Assessment (IEA) of this area. We analyzed fish distribution and abundance information, to improve our understanding of ...
