Summary
Abstract: The ship survey was performed from 22 July 1991 to 30 August 1991 to estimate the abundance and spatial distribution of harbor porpoises. The study area, covering approximately 13,300 nm , was from Port Clyde, ME to 2 St. John, New Brunswick over to the Nova Scotian coast, up to Liverpool, Nova Scotia.

Purpose: PRIMARY OBJECTIVES
1) Estimate the abundance of harbor porpoises in the Gulf of Maine - Bay of Fundy - Nova Scotia area. 2) Investigate if there are any spatial distribution patterns of the harbor porpoises, and if those patterns are correlated with water depth or harbor porpoise group size.

SECONDARY OBJECTIVES
1) Estimate the abundance and spatial distribution of other cetaceans.
