Written by OBIS-USA using excerpts from MRRI and SEAMAP-SA Homepages
MRRI staff, funded by the Southeast Area Monitoring and Assessment Program - South Atlantic (SEAMAP-SA) of the National Marine Fisheries Service (NMFS) have been conducting a shallow water trawl survey in the coastal zone of the South Atlantic Bight since 1986. SEAMAP-SA Shallow Water Trawl Survey cruises are conducted each year ... in Spring (mid-April to the end of May), Summer (mid-July to mid-August), and Fall (the first of October to mid-November).
The goal of this project is to monitor the status and trends of coastal species in the South Atlantic Bight, including fish, shrimp, crabs, horseshoe crabs, sea turtles, mantis shrimp, and squid, in order to amass a long-term data base for research and fisheries management use. Twenty-seven finfish and decapod species of key commercial or recreational interest, all sharks, all marine turtles, and horseshoe crabs are considered to be priority species. The project collects abundance and biomass data for all species, and lengths or widths for priority species. Priority species may have additional information such as individual weights, sex, sexual development, and/or tagging data recorded for them as well.
As the only coastal trawl survey that encompasses the entire Southeast region, this survey contributes to general knowledge of coastal species and aids numerous investigators and students by supplying data and specimens. This survey samples shallow coastal waters from Cape Hatteras, North Carolina to Cape Canaveral, Florida at depths from 15 to 30 feet. Samples are collected aboard the R/V Lady Lisa by towing paired 75 ft. mongoose-type Falcon Trawls for 20 minutes.
Purpose:
Written by OBIS-USA using excerpts from seamap.org
The Southeast Area Monitoring and Assessment Program (SEAMAP) is a cooperative program to facilitate the collection, management, and dissemination of fisheries independent data from the waters of the southeastern United States. Data collected via SEAMAP are relied upon by government agencies, the commercial and recreational fishing industries, ... researchers, and others to enhance knowledge of marine fisheries and their associated ecosystems.
The organizational structure of the program presently includes three operational components, SEAMAP-Gulf of Mexico, which began in 1981, SEAMAP-South Atlantic, implemented in 1983 and SEAMAP-Caribbean, formed in 1988.
Shallow water trawl surveys, a survey of Pamlico Sound, benthic characterization and bottom mapping projects are the primary activities in the South Atlantic.

Quality
Users are advised that ASTER SWIR data acquired from late April 2008 to the present exhibit anomalous saturation of values and anomalous striping. This effect is also present for some prior acquisition periods. Please refer to the ASTER SWIR User Advisory Document (https://lpdaac.usgs.gov/sites/default/files/public/aster/docs/ASTER...) for more details.
