Sampling Effort from NOAA NMFS SEFSC Bottom Longline Surveys (2001-2018)

browse graphicNOAA logo
Fisheries-independent bottom longline data from National Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Service (NMFS) Southeast Fisheries Science Center (SEFSC) Bottom Longline Surveys from 2001 to 2018 are used to map the distribution of survey effort. The number of bottom longline sets (effort) is summarized by 15 minute longitude by latitude blocks in which bottom longline sets were taken. The final summary is represented as a GIS polygon layer. The layer attributes include the central longitude (LON_GRIDC) and latitude (LAT_GRIDC), a polygon identifier (GRIDID) and the number of sets (N) for each 15 minute longitude by latitude block.

Source Datasets
  • NMFS/SEFSC/MSLABS Bottom Longline Survey Data
    • Description of Source: The National Marine Fisheries Service (NMFS), Southeast Fisheries Science Center (SEFSC), Mississippi Laboratories (MSLABS), Resource Survey Division conducts fishery-independent resource surveys throughout the southeast region of the United States. The primary goal of these surveys is to monitor the abundance, distribution, and health of living marine resources and their habitats. The NMFS SEFSC Bottom Longline surveys typically cover the continental shelf from Brownsville, TX to the Dry Tortugas FL in depths ranging from 9 to 360 meters. The survey collects a variety of biological and environmental information. Data are available upon request.

Processing Steps
  • 2015-04-22T00:00:00 - NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
