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 ... Read More
Effective management of shellfish harvest in the US relies on timely and accurate information about the shellfish habitat and the factors that impact it. In some areas, poor water quality ... Read More
We synthesized biological, chemical, and physical data from six watersheds in the Chesapeake Bay to assess impacts of land use on aquatic ecosystem health. The findings from this study are ... Read More
We are building models to assess relationships between chemical contamination in the environment and human activity. By evaluating variables such as land use, population density, community infrastructure and business locations, ... Read More
Since 1986, NOAA’s Mussel Watch Program has monitored the nation’s coastal waters for chemical contaminants and biological indicators of water quality. The program is being redesigned to adopt a rotating ... Read More
A recent report released by the National Centers for Coastal Ocean Science (NCCOS)found relationships between land use, water quality, and several important aquatic organisms in certain tributaries of the Chesapeake ... Read More
NCCOS scientists and their partners have identified a link between inter-annual patterns of precipitation and air temperature and fecal coliform levels inshellfish harvest waters in Maryland's portion of the Chesapeake ... Read More
Scientists from NCCOS are partnering with the Maryland Department of Natural Resource (MD-DNR) to launch a monitoring project in the Chesapeake Bay designed to survey the magnitude and distribution of ... Read More
The harvest of seafood from the Chesapeake Bay, which contributes billions of dollars to local and state economies, is just one of the key aquatic ecosystem services threatened by land-based ... Read More
NOAA’s National Status and Trends (NS&T) Mussel Watch Program conducted regional pilot studies to assess the magnitude and distribution of contaminants of emerging concern (CEC) in shellfish and sediment from different coastal zones. In 2015, oyster and surficial sediment samples ... Read More
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 ... Read More
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 ... Read More
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 ... Read More
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 ... Read More
The purpose of this manual is to provide a framework for the assessment of ecosystem health that may be adapted, or used in whole or part for application to other regions. Methods are provided for all aspects from sampling design ... Read More
