Projects
Assessing the Threat of Hypoxia to Coral Reefs
We are examining the impact of low-oxygen (hypoxia) stress on coral reef ecosystems. Coral reefs are in decline, and human-assisted restoration is actively trying to reverse this trend. Our project ...
Assessment of the Beneficial Use of Dredged Sedime...
Navigation channels across the country require regular maintenance dredging to avoid infilling with sediments and becoming impassible. In an experimental strategy that is often referred to as “beneficial use,” sediments ...
Evaluating Risk of Tidal Marsh Inundation and Mone...
We are identifying the coastal wetlands in Georgia, South Carolina, and Delaware Bay that are most vulnerable to sea-level rise and quantifying the value of benefits they provide. We are ...
How will Climate Change Affect Harmful Algal Speci...
We are supporting research that will determine how future increases in temperature and ocean acidity will affect harmful algal bloom species (HABs) and their grazers. Light micrograph of Karlodinium veneficum ...
Integrated Modeling of the Effects of Sea Level Ri...
We are advancing coastal dune and marsh modeling of the barrier islands, estuary and interior marshes in the Mississippi Sound to evaluate trade-offs between coastal management strategies and proposed restoration efforts ...
Keeping it in the System: Beneficial Use of Dredge...
We are developing a framework and process for matching dredging needs with opportunities for beneficial use of the sediment at local marshes, to help marshes keep up with sea level ...
Living with Sea Level Rise in the Texas Coastal Be...
We are using modeling to identify the best locations along the Texas Coastal Bend where natural and nature-based features (NNBF) can be used to address the effects of sea level ...
Modeling, Visualizing, and Communicating Nor'easte...
We are working to inform and improve coastal resource management and resilience to extreme weather events (e.g., Nor’easters and hurricanes) whose impacts are magnified with sea level rise. The project ...
Pavement Resilience to Sea Level Rise and Potentia...
We are investigating the coastal processes and hazards that damage roadway pavement. This work combines hydrodynamic, groundwater, and pavement models, along with an adaptation impact assessment, to understand overtopping and ...
Predicting Impacts of Sea Level Rise in the Northe...
We are assessing the impacts of sea level rise and coastal storms on marshes and oyster habitats in the northern Gulf of Mexico through the development of predictive models that ...

2020 State of Kachemak Bay Report Now Available...
The 2020 yearly status report on the marine ecosystem in Kachemak Bay, Alaska, is now available to the public. Kachemak Bay had a frigid start to 2020, followed by warmer ...
Workshop Report Defines Agenda for Integrated Rese...
Credit NOAA OAP. NOAA’s Ocean Acidification Program (OAP) and NCCOS have published the proceedings of the virtual Harmful Algal Blooms and Ocean Acidification Workshop in a NOAA Technical Memorandum (OAR-OAP-3) ...
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 ...
Researchers Evaluate Long-term Effect of Adding Sa...
NCCOS-sponsored research assessed the effectiveness of beach and dune nourishment on the morphological resilience of Dauphin Island, Alabama, for a 30-year period of beach management. Overall, the researchers found that ...
Wetlands in Intermittently Closed Estuaries Can Bu...
Along the U.S. Pacific Coast, many estuaries are not permanently open to the ocean, but shift between open and closed states. A NCCOS-supported study tested the hypothesis that intermittently-closed estuary ...
Communicating and Understanding Ecosystem Services...
NCCOS-funded researchers from six institutions report on insights and lessons learned from stakeholder engagement. The engagement was conducted during a multi-year transdisciplinary project focused on quantifying and communicating the benefits ...
Human Influences on Beach Loss (and Growth) in Ora...
Beaches are highly dynamic and their shape and size is the product of sediment being transported to the coast by rivers and bluff erosion and then shaped by physical forces ...
Management of Wetland Impoundments for Fish, Mosqu...
Suisun Marsh (CA) collage. Credit USDOI et al, 2011. In San Francisco Bay’s Suisun Marsh, NCCOS sponsored research compared the plant species diversity, abundance, and community composition among natural tidal ...
Story Map Highlights Marsh Vulnerability in San Fr...
A “marsh organ,” used to study the effects of different water levels on marsh vegetation and marsh migration, is deployed at the project study site. Credit: OSU and USGS. An ...
