Researchers were quick to point out, however, that this correlation is not conclusive because the data set used was compiled to
track bowhead whale migration routes, not polar bears.
Movement analysis of one satellite -
tracked killer whale travelling as part of a group of 20 + killer whales showed that the whale remained in Prince Regent Inlet and in the northern part of the Gulf of Boothia from late August until early October, when locations overlapped aggregations of marine mammal prey species, including seals, narwhal, and
bowhead whales (Matthews et al. 2011).
