Spring Bottom Trawl Survey
The standardized NEFSC Spring Bottom Trawl Survey was initiated in 1968 and covered an area from Cape Hatteras, NC, to Nova Scotia, Canada, at depths >27m. Throughout the years, coverage has extended as far south as Florida and sampling depths have ranged from <27m to 366m. Currently, the survey coverage is from Cape Lookout, NC to Nova Scotia, including Georges Bank and the Gulf of Maine. The depth range minimum is >18 m, as the result of a change in the sampling platform. This has resulted in the exclusion of many inshore strata.
