NEFSC Survey 1998 2Entry ID: seamap62
Abstract: The survey was performed on the R/V Abel-J from 06 July to 04 August 1998 (Leg I) , and from 08 August to 06 September 1998 (Leg II) starting and ending in Woods Hole, MA. The study areas in Leg I and Leg II, respectively, were from Cape Cod to Virginia, and from Cape Cod to Halifax, Nova Scotia. Both study areas extended from the 100m depth contour to the Gulf Stream.
Purpose: Primary objectives of the survey were: (1) estimate the abundance of strategic species of pelagic dolphins and whales, such as, common, spotted and bottlenose dolphins, and sperm, pilot, and beaked whales, (2) estimate the abundance of all other dolphins and whales detected in these waters.
Secondary objectives included: (1) collect bongo, CTD, water depth and temperature data to correlate with ... the spatial distribution of the marine mammals, (2) conduct marine mammal photographic and video identification studies, and (3) collect biopsy samples.
SUPPLEMENTAL INFORMATION: In addition to the sighting data, effort data was recorded every half hour or whenever conditions change. This dataset, therefore, should be used with the effort data.
