NEFSC Aerial Survey - Experimental 2002Entry ID: seamap107
Abstract: The survey was conducted on the NOAA DeHavilland Twin Otter DHC-6,
Series 300 aircraft from 19 July to 16 August 2002. The flights were based out
of Otis Airbase from 19 July to 02 August 2002, and based out of Hancock
County/Bar Harbor Airport in Trenton, Maine from 02 August to 16 August 2002.
The southern border of the study area was south of Long Island, NY, the
northern border was in the Bay of Fundy north of St. John, New Brunswick, the
western border was the US coast line, and the eastern border was about 64.5°W
(west of Halifax, Nova Scotia).
Purpose: The primary objective of this survey is to determine the feasibility
of the Circle-back method that estimates abundance of cetaceans and turtles
which includes an estimate of g(0), the probability of detecting a group on the
track line. First, the practice issues of conducting the survey in the field
will be assessed, then the analytical issues will be investigated after the
data are collected. ... The secondary objective is to estimate the abundance of
animals using this new method. The third objective is to collect surface water
temperature information during the survey to be used in a description of the
habitat of the different species of cetaceans and turtles.
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.
