Report on studies to monitor the interactions between offshore geophysical exploration activities and bowhead whales in the Alaskan Beaufort Sea, Fall 1982
Technical Report
·
OSTI ID:5693299
A total of 34 survey flights were initiated between 27 August and 4 October 1982 to assess the potential effects of marine geophysical survey work on westward migrating bowhead whales (Balaena mysticetus). No overt changes in whale behavior were observed that could unequivocally be interpreted as responses to seismic noise, with the possible exception of huddling behavior observed on 14-15 September that may have been caused by the onset of seismic sounds. Statistical analyses were performed on four categories of respiratory behavior (blows per surfacing, mean blow interval per surfacing, surface times and dive times) to test for differences between times when whales were and were not exposed to seismic sounds.
