Killer Whale Calls Analysis Off Iceland and Norway
Underwater recordings of killer whale calls were made off Norway and Iceland from 1983 to 1985 in association with efforts to photograph dorsal fins and saddles for identification of individual whales. Researchers collected at least eight hours of recordings near at least two pods off Norway and eight hours of recordings near at least five pods off Iceland. A preliminary description of discrete call types for whales from each area was completed using methods developed on well-known pods of killer whales off British Columbia and Washington state. Twenty-four discrete calls were described for whales off Icelands; 23 discrete call types were identified for whales off Norway. There was little evidence of calls shared between Icelandic and Norwegian pods.
