Description: The Coastal Trawl Survey (CTS; previously known as the Shallow Water Trawl Survey or Coastal Survey) is conducted by the South Carolina Department of Natural Resources – Marine Resources Division (SCDNR-MRD). The CTS began in 1986 and standardized activities have been in place since 1990. This survey provides long-term, fishery-independent data on seasonal abundance and biomass of finfish, elasmobranchs, decapod and stomatopod crustaceans, sea turtles, horseshoe crabs, and cephalopods that are accessible by high-rise trawls in coastal nearshore waters, specifically those between Cape Hatteras, North Carolina, and Cape Canaveral, Florida. The CTS samples the full spatial range in multiple seasons each year. Historically, multi-legged cruises were conducted within three sampling seasons: Spring (April - May), Summer (July - August), and Fall (September - November). This group of data layers includes station and monitoring data for the 2023 monitoring season, which includes 4 layers: stations, specimen, length frequency, and abundance.Station (Event): Includes information such as location, collection date, and abiotic factors. A sampling event is the deployment of any gear, whether it collects biotic or abiotic factors.Specimen: Includes (SPECIMEN) field with unique information for single individuals of a species (e.g. length, weight, sex, and disease disposition).Length frequency: For a SPECIE(S), it includes species-specific length frequency information related to the subsample (relative number measured) and the total (total number collected) within each COLLECTION.Abundance: For COLLECTION and SPECIE(S) includes information pertaining to the gear used and the sampling effort, including any subsampling regime as well as information related to the total catch (e.g. total abundance and total weight) for any species with available data.
