I am working on a project where I have to assess the effects of close approaches of fin, humpback, sei, humpback, north Atlantic right and sperm whales for the purpose of biopsy sampling, suction cup tagging and photo identification. Whales of all ages (2 weeks and older) and reproductive stages including mother/calf pairs would be approached no closer than 100 meters by a large research vessel at which time a small inflatable would be deployed to approach the whales to a distance of 10 meters. Can anyone guide me to any empirical data for any responses (behavioral or otherwise) to close approach, particularly for mother/calf pairs?
Thanks.
