Summary
Abstract: 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: Collect line transect data to 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). 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.
