Projects

A Pilot Assessment of Fish Habitat in Choptank Riv...

Fish and shellfish populations depend on healthy habitats. To help understand and manage these habitats in the Chesapeake Bay, we will develop a GIS-based analytical framework that might be used ...

An Ecological Assessment to Support NOAA’s Choptan...

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 ...

AquaSpace – An Ecosystem Approach to Making Space ...

Aquaculture is a large and growing segment of seafood production because capture fisheries production continues to decline. A major challenge to the expansion of marine aquaculture in most nations is ...

Assessing Blue Carbon Storage at Sites Restored th...

To mitigate the impacts of climate change, there is a global initiative to quantify and award carbon credits for restoration and conservation of blue carbon habitats. These habitats are known ...

Bacterial and Pharmaceutical Pollution from Agricu...

We studied how the use of animal waste as fertilizer on agricultural lands might influence the health of surrounding water bodies in the Chesapeake Bay. We analyzed rainwater runoff and ...

Can Meadows of Underwater Grasses Help Mitigate th...

Ocean acidification (OA) in the natural environment co-occurs with other stressors, such as temperature and low oxygen, creating complex ecological interactions that are difficult to manage in restoration and aquaculture ...

Can Oyster Aquaculture in the Chesapeake Bay Flour...

We are supporting research that will explore how the Eastern oyster will grow and survive under future environmental conditions and determine if there are environmental or economic thresholds (“tipping points”) ...

Characterization of an Algicidal Agent Produced by...

We examined a biological control agent isolated from a bacteria species that may provide a mechanism for halting the growth of certain types of toxic dinoflagellate harmful algal blooms. We ...

Chesapeake Bay Climate Sensitivity Assessment

The Chesapeake Bay is one of the largest estuaries in the world, economically valuable for its productive habitats, valuable fisheries, and recreational opportunities. However, it is clear that climate changes ...

Chesapeake Bay Vibrio Pathogen Forecast

We forecast where and when pathogens are most likely to be found in the Chesapeake Bay, based on the salinity and temperature of the water. Public health officials use our ...

Right Plants in Right Places Key to Island Restora...

Natural breakwaters — such as marshes, islands, and oyster reefs — help protect people and property from coastal flooding by damping wave energy and slowing storm surge. Despite these advantages, ...

Maps, Tools & Applications

This Data Explorer Map contains ecological and socioeconomic datasets including management boundaries, human use activities, fish and oyster surveys, and benthic habitats in the NOAA Choptank Habitat Focus Area (HFA) Ecosystem Assessment. The tool allows managers, stakeholders and the general public to visualize data that assists with decision-making about management of the ecosystem in the Choptank watershed.

Data & Publications

Biological, chemical, and physical data from the Phytoplankton Monitoring Network from 13 Sep 2001 to 7 Mar 2013 (NODC Accession 0117942)

The Phytoplankton Monitoring Network (PMN) is a part of the National Centers for Coastal Ocean Science (NCCOS). The PMN was created as an outreach program to connect volunteers and professional scientists in the monitoring of marine phytoplankton and harmful algal ...

Biotic resistance, disturbance, and mode of colonization impact the invasion of a widespread, introduced wetland grass

Disturbance and biotic resistance are important factors driving plant invasions, but how these factors interact for plants with different modes of colonization (i.e., sexual and asexual) is unclear. We evaluated factors influencing the invasion of nonnative Phragmites australis, which has ...

Characterization of Acetyl-CoA Carboxylases in the Basal Dinoflagellate Amphidinium carterae

Dinoflagellates make up a diverse array of fatty acids and polyketides. A necessary precursor for their synthesis is malonyl-CoA formed by carboxylating acetyl CoA using the enzyme acetyl-CoA carboxylase (ACC). To date, information on dinoflagellate ACC is limited. Through transcriptome ...

Characterization of Toxic Impacts on Living Marine Resources in Tidal Rivers of the Chesapeake Bay

In 1999, the Chesapeake Bay Program completed a survey of existing data on chemical contaminants and the potential for bioeffects in 38 tidal river systems of Chesapeake Bay. This review led to the identification of 20 areas for which there ...

Chesapeake Bay Activity Book

An activity book designed to introduce elementary school children to the animal and plant life and ecology of Chesapeake Bay ...

Coastal Ecological Assessment to Support NOAA’s Choptank River Complex Habitat Focus Area: Tred Avon River

In the Tred Avon River, an important tributary of the Choptank River, we assessed the impacts of land use on the health of the aquatic ecosystem in a 3-year field study (2015-2017). In our analysis of information collected during the ...

Coastal ecosystem assessment of Chesapeake Bay watersheds: A story of three rivers, the Corsica, Magothy, and Rhode

This assessment explored linkages between land use and aquatic ecosystem health. Three watersheds (Corsica, Magothy, and Rhode rivers) with variable dominant land-use patterns (agriculture, suburban/residential, and mixed-use, respectively) were examined. The health of each habitat was assessed using a suite ...

Coastal Ecosystem Assessment of Chesapeake Bay Watersheds: Land Use Patterns and River Conditions

In coastal and estuarine regions, land use can have a profound impact on aquatic ecosystem health. In the Chesapeake Bay watershed, agriculture and urbanization have transformed major portions of the landscape, though some areas of undeveloped land remain. This document ...

Correlation and Prediction of Land-Based Pollution Impacts on Sediment Contaminant Concentrations within National Estuarine Research Reserves of the Southeastern US and Selected Chesapeake Bay Watersheds

OpenNSPECT is a raster-based GIS model that estimates runoff, pollution and erosion in a GIS setting. NOAA’s National Centers for Coastal Ocean Science (NCCOS) has conducted a series of regional ecological assessments throughout many estuarine and coastal shelf areas of ...
