Projects

Science in Support of Adaptation Planning for Clim...

The Chesapeake Bay, the largest estuary in the United States, provides people with valuable ecosystem services. Impacts from climate change, including sea level rise and changes in precipitation, can threaten ...

Scientific Support for Mesophotic and Deep Benthic...

We are working on a collaborative set of projects to better understand and restore mesophotic and deep benthic communities in the Gulf of Mexico impacted by the 2010 Deepwater Horizon ...

Seafloor Characterization of the U.S. Caribbean

Since 2004, we have been conducting seafloor mapping of the U.S. Caribbean, to fill critical informational gaps to support improved management measures in the U.S. Virgin Islands and Puerto Rico, ...

Seafloor Substrate Mapping and Model Validation in...

In support of the Bureau of Ocean Energy Management, NCCOS characterized seafloor habitats and fish distributions in coastal waters of New York. The New York Wind Energy Area (79,350 acres), ...

Seasonal Forecasting of Karenia brevis Red Tide Bl...

This project is developing modeling tools to improve short term and seasonal predictions of toxic red tide Karenia brevis blooms in the Gulf of Mexico West Florida Shelf. The project ...

Setting Shared Goals for South Florida’s Marine an...

We facilitated a process to identify the characteristics and key regulating processes of a sustainable South Florida coastal marine ecosystem. Using the best available science from academia, agencies, and non-governmental ...

Shallow Water Hypoxia: Tipping the Balance for Ind...

We are investigating the impacts of extreme daily fluctuations in oxygen and pH on fish and invertebrates in the Chesapeake Bay. The modeling tools we produce will improve the ability ...

Shallow-water Benthic Habitat Mapping of Northeast...

We developed benthic habitat maps for shallow coral reef areas (< 35 m) around Northeast Puerto Rico and Culebra Island. These maps are helping scientists and local managers develop place-based ...

Sharing Simple and Fast Algal Toxin Detection Test...

Toxins produced by harmful algae accumulate in shellfish, causing human illness and marine animal mortalities. We have developed a rapid, cost-effective test that measures algal toxins in shellfish to protect ...

News

Location, Inundation, and Nitrogen Availability Dr...

Two publications resulting from U.S. Department of Defense-funded research to support ecosystem-based management in coastal military installations have been published in the Journal of Geophysical Research-Biogeosciences. The research was a ...

Podcast Explores Economics of Natural vs Armored S...

Some oceanfront landowners in Neskowin, Oregon, have chosen to use rock revetments, or rip-rap, to protect their properties from erosion. Their decision has implications for property values, public access, and ...

Third Advisory Panel Workshop on Hypoxia Effects o...

The third Advisory Panel Workshop on Hypoxia Effects of Fish and Fisheries was held virtually on December 14, 2020 as part of an NCCOS NGOMEX project led by Dr. Kim ...

Urea-based Fertilizer Promotes Blue-Green Algal Bl...

NCCOS-supported Research Aids Site Selection for C...

NCCOS-supported researchers from the University of Florida and Smithsonian Marine Station paired water quality sensors with coral outplants to develop data-driven criteria for selection of restoration sites in the Florida ...

Survey Finds Coastal Carolina Residents Support Of...

Reviews of Our Current Understanding of Harmful Di...

In a recently released book on dinoflagellates, three chapters update knowledge of and changing views for the red tide alga Karenia brevis and the estuarine Pfiesteria-like dinoflagellates Pfiesteria piscicida and ...

NOAA Evaluates Using Mussel Watch Program to Monit...

Amy V. Uhrin (left), NOAA’s Marine Debris Program, and Ed Johnson, NOAA's Mussel Watch Program, collect samples of driessenid mussels on a NOAA/GLERL research vessel in Lake Michigan, summer 2018 ...

Marine Heatwaves Fuel Harmful Algal Blooms Off US ...

Recreational razor clamming can bring thousands of visitors to the Washington coast. Toxins concentrated in razor clam and Dungeness crab fisheries have caused economic damage to coastal communities. Repeated marine ...

Hydro-Financial Watershed Modeling for Environment...

NCCOS has sponsored a study to determine the fair interest rate and return period for a new type of financial instrument called an Environmental Impact Bond. The study examines feasibility ...

Data & Publications

Landscape-Level Variation in Disease Susceptibility Related to Shallow-Water Hypoxia

Diel-cycling hypoxia is widespread in shallow portions of estuaries and lagoons, especially in systems with high nutrient loads resulting from human activities. Far less is known about the effects of this form of hypoxia than deeper-water seasonal or persistent low ...

Limitations of gravity models in predicting the spread of Eurasian watermilfoil

The effects of non-native invasive species are costly and environmentally damaging, and resources to slow their spread and reduce their effects are scarce. Models that accurately predict where new invasions will occur could guide the efficient allocation of resources to ...

Linking Coasts and Seas to Address Ocean Deoxygenation

Accelerated oxygen loss in both coastal and open oceans is generating complex biological responses; future understanding and management will require holistic integration of currently fragmented oxygen observation and research programmes ...

Linking environmental conditions and ship movements to estimate invasive species transport across the global shipping network

Some nations, and the International Maritime Organization, are moving towards requirements for managing ballast water to reduce the number of alien species transported and released. These and other measures will be most efficient when targeted at ships posing the greatest ...

Linking molecular microbial ecology to geochemistry in a coastal hypoxic zone

Multiple environmental mechanisms have been proposed to control bottom water hypoxia (<2 mg O2 L?1) in the northern Gulf of Mexico Louisiana shelf. Near-bottom hypoxia has been attributed to a direct consumption of oxygen through benthic microbial respiration and a ...

Linking the Abundance of Estuarine Fish and Crustaceans in Nearshore Waters to Shoreline Hardening and Land Cover

Human alteration of land cover (e.g., urban and agricultural land use) and shoreline hardening (e.g., bulkheading and rip rap revetment) are intensifying due to increasing human populations and sea level rise. Fishes and crustaceans that are ecologically and economically valuable ...

Local and regional disturbances associated with the invasion of Chesapeake Bay marshes by the common reed Phragmites australis

Invasions are dynamic as both the invading organism and the invaded ecosystem change. Intrinsic changes to the invader (invasion process) can involve population level genetic and reproductive changes. Extrinsic changes (invasion effect) occur to the environment that is invaded (e.g., ...

Long-distance dispersal and vertical gene flow in the Caribbean brooding coral Porites astreoides

To date, most assessments of coral connectivity have emphasized long-distance horizontal dispersal of propagules from one shallow reef to another. The extent of vertical connectivity, however, remains largely understudied. Here, we used newly-developed and existing DNA microsatellite loci for the ...

Long-term decline in the calanoid copepod Acartia tonsa in central Chesapeake Bay, USA: An indirect effect of eutrophication

A long-term abundance record of the calanoid copepod Acartia tonsa in the Maryland portion of Chesapeake Bay was compiled from 1966 to 2002. A significant downward trend in the summertime abundance of Acartia tonsa was found in central Chesapeake Bay ...

Long-term monitoring of ecological conditions in Gray's Reef National Marine Sanctuary: Comparison of soft-bottom benthic assemblages and contaminant levels in sediments and biota in spring 2000 and 2005

As part of an ongoing program of benthic sampling and related assessments of sediment quality at Gray's Reef National Marine Sanctuary (GRNMS) off the coast of Georgia, a survey of soft-bottom benthic habitats was conducted in spring 2005 to characterize ...
