A Large Aggregation of Bowhead Whales (Balaena Mysticetus) Feeding near Point Barrow, Alaska, in Late October 1992
On 17 October 1992, during aerial surveys to monitor the bowhead whale migration across the Beaufort Sea, we encountered a large aggregation of feeding bowheads about 35 km NE of Barrow, Alaska. Nineteen sightings, for a total of 56 bowhead whales, were made over an area of open water and new ice. M...
