Projects

Promoting Innovative Transformational Coastal Adap...

Coastal marshes and wetlands can attenuate wave energy and reduce flood risk. This project will model and evaluate the costs and benefits of various nature based solutions and management options ...

Scenarios and Tradeoffs: Providing Useful Models t...

Many agencies at the federal, state, and regional level need to use ecosystem models to help them predict the results of different management actions on coastal ecosystems. These models weigh ...

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 ...

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, ...

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 ...

Spatial Characterization to Support Development of...

We synthesized data to support development of an integrated management plan for Puerto Rico’s Northeast Marine Corridor. We used spatial data to characterize the area, identify priority biological and ecological ...

Testing Feasibility of Directly Seeding Oyster Ree...

We are testing the feasibility of "direct setting," a new method for seeding oyster reefs. Traditional reef seeding in areas with low natural-recruitment uses hatchery-produced juvenile oysters attached to cultch ...

Toward a Predictive Understanding of Cochlodinium ...

Large blooms of Cochlodinium polykrikoides have occurred throughout the lower Chesapeake Bay and its tributaries in recent decades and appear to be followed by increasingly intense blooms of the ichthyotoxic ...

Tracking Fish Use of Engineered Habitats

In partnership with the U.S. Army Corps of Engineers Engineering With Nature® Initiative, we are using acoustic telemetry to track fish movements in engineered and restored habitats to determine how ...

Transitioning to Operations NOAA Supported Statist...

The Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA) mandates the development of scientific tools for natural resource managers to address hypoxia in coastal ecosystems. In response, NCCOS ...

Water Cleaning Capacity of Oysters Could Mean Extr...

Oysters are one of the most valuable fisheries in Chesapeake Bay, with annual commercial landings valued at more than $40 million. A large part of this harvest comes from aquaculture ...

Tenth Harmful Algal Bloom Symposium Highlights NCC...

Credit. 10th US Symposium on Harmful Algae. The 10th US Symposium on Harmful Algae, held November 3-8, 2019, focused on emerging harmful algal blooms (HABs) in the US, crossing the ...

Swan Island Restoration Begins in Chesapeake Bay (...

Coastal islands and marshes in Chesapeake Bay are disappearing, along with the ecosystem services and shoreline protection benefits they provide. Within the last half century, the cumulative effects of shoreline ...

Data & Publications

Is global ocean sprawl a cause of jellyfish blooms?

Jellyfish (Cnidaria, Scyphozoa) blooms appear to be increasing in both intensity and frequency in many coastal areas worldwide, due to multiple hypothesized anthropogenic stressors. Here, we propose that the proliferation of artificial structures – associated with (1) the exponential growth ...

Karmitoxin: An Amine-Containing Polyhydroxy-Polyene Toxin from the Marine Dinoflagellate Karlodinium armiger

Marine algae from the genus Karlodinium are known to be involved in fish-killing events worldwide. Here we report for the first time the chemistry and bioactivity of a natural product from the newly described mixotrophic dinoflagellate Karlodinium armiger. Our work ...

Land Use and Salinity Drive Changes in SAV Abundance and Community Composition

Conserving and restoring submerged aquatic vegetation (SAV) are key management goals for estuaries worldwide because SAV integrates many aspects of water quality and provides a wide range of ecosystem services. Management strategies are typically focused on aggregated abundance of several ...

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 ...

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 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-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 ...

Long-term trends in Chesapeake Bay seasonal hypoxia, stratification, and nutrient loading

A previously observed shift in the relationship between Chesapeake Bay hypoxia and nitrogen loading has pressing implications on the efficacy of nutrient management. Detailed temporal analyses of long-term hypoxia, nitrogen loads, and stratification were conducted to reveal different within-summer trends ...
