Description

Sightings data were collected by the Mingan Island Cetacean Study (MICS) from 1980 to 2008 with annual surveys realised in the Gulf of St. Lawrence between the end of may and early november. Surveys were conducted using inflatable boats enabling the close approaches necessary to photograph and biopsy blue whales. The aim of this project was to provide additional information for designating blue whale critical habitat as required under the Canadian Species at Risk Act. For more details consult the following report: Ramp, C. and Sears, R. 2013.
