United States Environmental Protection Agency Office of Research and Development Washington DC 20460 EPA/620/R-02/001b April, 2002 Barataria - Terrebonne, Louisiana National Estuary Program 2001 Intensive Sampling Design >&EPA Coastal Communications Barataria-Terrebonne, Louisiana National Estuary Program National Coastal Assessment ORO/OW/Region 6/BTNEP/L&WF Background The U.S. EPA's National Coastal Assessment (NCA) is a multi-year partnership among EPA's Office of Research and Development (ORD), EPA's Office of Water (OW), EPA's Regional Offices, all coastal states, and selected territories. The effort described here is conducted in special partnership with the Barataria-Terrebonne National Estuary Program (BTNEP). This joint effort will evaluate the changing condition of tributaries to and coastal areas of the BTNEP. Information will also be shared with Louisiana Department of Wildlife and Fisheries (LDWF) and EPA Region 6, and contribute to state and regional assessments. The effort is being coordinated by the ORD National Health and Environmental Effects Research Laboratory's Gulf Ecology Division in Gulf Breeze, Florida. National Coastal Assessment Strategy The National Coastal Assessment is a strategic partnership between EPA and the coastal states and other federal agencies. Each state or NEP uses a compatible probabilistic design and a common set of environmental indicators (see Table below) to survey its coastal resources and assess their condition. These estimates can then be aggregated to assess conditions at the EPA regional, biogeographical, and national levels. All data will be made available for public access on the Internet. The map shows the coastal areas included in the 2001 survey and the number of sampling sites in estuarine waters of Louisiana.
