Difference in Simulated Low-Frequency Sound Propagation in the Various Species of Baleen Whale
Whales found in the north Pacific are known to migrate over several thousand kilometers, from the Alaskan coast where they heartily feed during the summer to low latitude waters where they breed during the winter. Therefore, it is assumed that whales are using the “deep sound channel” for their long...
