Abstract

The cruise period was from 06 August - 07 September 1995. The area of operation was Georges Bank and waters east of Cape Cod.

Purpose

The primary objectives of the survey were to: (1) conduct line-transect population surveys within the study area, and (2) investigate cetacean distribution on the southern portion of Georges Bank, principally between the 30 f isobath and 10 nm beyond the 1000 f curve. Secondary objectives included: (1) collecting information on the relationship cetaceans and oceanographic features, (2) the collection of CTD and zooplankton data, (3) conducting marine mammal photographic
identification studies using a rigid bottom inflatable boat and (4) collecting biopsy samples for stock identification and contaminant studies.

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.
