Summary
Abstract: Platform: NOAA 57 Twin Otter Aircraft Dates: July 18 - August 21 1998
Location: Inshore areas from 38° north Latitude on the US east coast to Cape
Breton Island, Nova Scotia, Canada This aerial survey was flown in conjunction
with shipboard surveys being conducted during the same time frame. The R/V
Abel-J was chartered to conduct line transect surveys offshore from 38°N
offshore from approximately 40 fathoms to the Gulf Stream, and north to the
Northeast Channel east of Georges Bank. The aerial survey covered all inshore
areas from the beach to the 40 fathom boundary of the shipboard survey and
extended east to Cape Breton Island, Nova Scotia, Canada.

Purpose: Estimate abundance for as many species as possible.

SUPPLEMENTAL INFORMATION: Data correction 03/08/06
Humback whale was mistakenly linked to Balaenidae (180531). It is now linked to
Megaptera novaeangliae (180530). The survey was flown using line transect
methodology. There were three observers at all times, left bubble window, right
