Summary
Abstract: The ship survey was conducted from 06 August 1995 to 05 September 1995, beginning and ending in Woods Hole, MA. The study area covered approximately 12,600 nmi2 , and included the area bounded by Portland, ME to St. John, New Brunswick, to the southern tip of Nova Scotia. This cruise was part of a large scale marine mammal sighting survey which consisted of two legs (each approximately a month long) on each of two ships, and a six week aerial survey which was conducted concurrently with vessel operations. The entire study area was from Chesapeake Bay, VA, USA to the Gulf of St. Lawrence, Canada.

Purpose: The objectives of this survey were to: 1) Estimate the abundance of harbor porpoises in the Gulf of Maine - Bay of Fundy - Scotian shelf area using two different field collection and analysis methods. 2) Determine the spatial distribution and estimate the abundance of other cetaceans found in the above area. 3) Conduct a comparison between sighting rates and spatial distribution of harbor ...
