Description

Original provider: NOAA Northeast Fisheries Science Center (NEFSC) Dataset credits: NOAA Northeast Fisheries Science Center (NEFSC) Abstract: The survey was performed on the R/V Abel-J from 6 July to 4 August 1998 (Leg I), and from 8 August to 6 September 1998 (Leg II) starting and ending in Woods Hole, Massachusetts. The study areas in Leg I and Leg II, respectively, were from Cape Cod, Massachusetts to Virginia, and from Cape Cod, Massachusetts to Halifax, Nova Scotia, Canada. Both study areas extended from the 100 m 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, and 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 were recorded every half hour or whenever conditions changed. This dataset, therefore, should be used with the effort data.

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, and 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.
