NEFSC Survey 1991
Entry ID: seamap111

Abstract: Two ship surveys were performed simultaneously. The primary survey,
using the 106 foot RV/ Abel-J, was from 22 July 1991 to 30 August 1991,
starting and ending in Woods Hole, MA. The study area, covering approximately
13,300 nm2, was from Port Clyde, ME to St. John, New Brunswick over to the Nova
Scotian coast, up to Liverpool, Nova Scotia. The supplementary survey, using
the 48 foot MV/ Sneak Attack, was from 3 August to 22 August, 1991. Their study
area was the inland bays from Penobscot Bay, ME to Machais Bay, ME

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. 2) Determine if ... View entire text
