Projects

Evaluating Nature-Based Solution Performance

We are evaluating the performance of three types of nature-based solutions: oyster reefs, coral reefs, and wetlands created from dredged sediments. We will examine project sites five or more years ...

Evaluation of Mitigation Strategies for Harmful Al...

We will assess the potential economic benefits of mitigation strategies for harmful algal blooms in the Dungeness crab fishery along the U.S. West Coast. Why We Care In 2015, the ...

Evidence on the Use of Built Structures for Coral ...

Amidst global declines in coral reefs, restoration practitioners and managers are increasingly considering incorporating built structures in restoration. However, information on how built structures have been used in coral restoration ...

Expanding the Southeast Alaska Tribal Ocean Resear...

This project expands existing harmful algal bloom (HAB) monitoring conducted by the Sitka Tribe of Alaska Environmental Research Laboratory (STAERL) to include testing shellfish for domoic acid and diarrhetic shellfish ...

Exploring and Characterizing the Seafloor of Chann...

We worked with staff at Channel Islands National Marine Sanctuary (CINMS) on three mapping related efforts: 1) developed a map of existing data to plan for future data collections; 2) ...

Fast Tool to Detect Toxic Shellfish

The marine food source and livelihood of tribes and communities along the Pacific coast are threatened by Pseudo-nitzschia blooms that produce domoic acid, a potent neurotoxin. To provide remote communities ...

HABs in the Kodiak Archipelago: HAB Monitoring and...

Locations of monitoring beaches for shellfish toxicity in the Chiniak Bay study area, Kodiak Archipelago, Alaska. The project will enhance an existing HAB monitoring framework built by the Kodiak Area ...

Hand-held Sensor for Domoic Acid Poisoning of Mari...

The algal toxin domoic acid (DA) poisons hundreds of marine mammals each year. Presently, first responders do not have access to sensors capable of rapidly and accurately monitoring DA for ...

Harmful Algal Bloom Community Technology Accelerat...

The project team will establish a California regional hub for harmful algal bloom data, technology, and knowledge transfer, and then expand or export these technological tools to other regions on ...

Harmful Algal Blooms Event Response: Responding to...

We helped Alaska state regulators, the shellfish industry, and community leaders initiate routine, rapid screening of noncommercial shellfish in southeast Alaska for paralytic shellfish poisoning (PSP) toxins. We also worked ...

Virtually Explore Shallow Water Mapping Priorities...

NCCOS scientists are working to conduct a data needs assessment for each of the seven U.S. coral reef management jurisdictions (Figure 1). The team has developed an interactive hub “Coral Reef ...

Climate Change Likely to Worsen Impact of Urban Ru...

The downtown Los Angeles skyline. Credit Wikimedia Commons. An NCCOS-funded study found that nutrient-laden, urban runoff is fueling algal blooms in Southern California's coastal waters that are acidifying the water ...

Real-time Data Aids Managers in Timing Decisions o...

NCCOS-supported instruments in Los Peñasquitos Lagoon are providing real-time data to Southern California managers and regulators on key physical parameters (dissolved oxygen, salinity, and water level) enabling them to determine ...

Algal Toxins Found in U.S. Seabirds

A publication sponsored in part by NCCOS presents a retrospective analysis of harmful algal bloom (HAB) related mortality events in California, Washington and Rhode Island between 2007 and 2018 involving ...

Long Term Research on the HAB Toxin Domoic Acid In...

A coalition of researchers funded by the NOAA Monitoring and Event Response for Harmful Algal Blooms (MERHAB) Program recently came together to co-locate an Environmental Sample Processor (ESP) off the ...

NCCOS Expands Monitoring of More Lakes, Coastal Ba...

With harmful algal blooms (HABs) occurring in the nation’s lakes, bays and sounds, NCCOS is expanding HAB monitoring and forecasting to these smaller water bodies which can be resolved by ...

Research Fills Gap in Understanding Greenhouse Gas...

New research by NCCOS scientists provides data to help fill a gap in our understanding of the fate of coastal wetland sediment carbon following disturbance events. Stored organic carbon in ...

Study Reviews Causes of Acidification in Large Est...

With ocean acidification threatening the health of aquatic organisms, a study funded by NCCOS, NOAA's Ocean Acidification Program, and the National Science Foundation reviewed a variety of processes that influence ...

Yessotoxins Responsible for Mass Shellfish Mortali...

Dying clams in Hood Canal (Rocky Bay, Washington, 2019). Credit: King et al, 2021. In the summers of 2018 and 2019, shellfish growers in Washington state were rocked by mass ...

Data & Publications

Climate change and larval transport in the ocean: fractional effects from physical and physiological factors

Changes in larval import, export, and self‐seeding will affect the resilience of coral reef ecosystems. Climate change will alter the ocean currents that transport larvae and also increase sea surface temperatures (SST), hastening development, and shortening larval durations. Here, we ...

Community ecology of mesophotic coral reef ecosystems

Given the global degradation of shallow-water coral reef ecosystems resulting from anthropogenic activities, mesophotic coral reef ecosystems (MCEs) are gaining attention because they are generally considered a de facto refuge for shallow-water species. Despite their inferred importance, MCEs remain one ...

Coupling ecology and GIS to evaluate efficacy of Marine Protected Areas in Hawaii

In order to properly determine the efficacy of marine protected areas (MPAs), a seascape perspective that integrates ecosystem elements at the appropriate ecological scale is necessary. Over the past four decades, Hawaii has developed a system of 11 Marine Life ...

Cruise Report for Patterns in Deep-Sea Corals Expedition 2016: NOAA ship Shearwater SW-16-08

The 2016 Patterns in Deep-Sea Corals expedition set out aboard the NOAA Ship Shearwater in August to study the distribution, ecology, and health of deep-water (30-300 m) gorgonian corals in response to the 2015 El Niño event. The research team ...

Cruise Report for Patterns in Deep-Sea Corals Expedition: NOAA ship Bell M. Shimada SH-15-03

Less than 50% of the Channel Islands National Marine Sanctuary seafloor has been mapped using multibeam echosounders to produce habitat characterizations at a map resolution suitable for resource management. This is important because deep-sea coral and sponge communities are known ...

Defining reef fish habitat utilization patterns in Hawaii: comparisons between marine protected areas and areas open to fishing

Over the past 4 decades, Hawaii has developed a system of Marine Life Conservation Districts (MLCDs) to conserve and replenish marine resources. These MLCDs vary in size, habitat quality, and management regimes, providing an excellent opportunity to test hypotheses concerning ...

Depth specialization in mesophotic corals (Leptoseris spp.) and associated algal symbionts in Hawaii

Corals at the lower limits of mesophotic habitats are likely to have unique photosynthetic adaptations that allow them to persist and dominate in these extreme low light ecosystems. We examined the host–symbiont relationships from the dominant coral genus Leptoseris in ...

Distribution of deep-water corals, sponges, and demersal fisheries landings in Southern California, USA: implications for conservation priorities

Deep-sea corals in Southern California are diverse and abundant but subject to multiple stressors, including bottom-contact fisheries using mobile and fixed gear. There is a need for more information on the distribution of these taxa in relation to the distribution ...

Distribution of Persistent Organic Contaminants in Canyons and on the Continental Shelf off Central California

The National Centers for Coastal Ocean Science, and the Office of National Marine Sanctuaries, in cooperation with the U.S. Geological Survey (USGS), University of California Moss Landing Marine Lab (MLML), and the Monterey Bay Aquarium Research Institute (MBARI), conducted ecosystem ...
