Acoustic Detections of Beluga Whales in the Northeastern Chukchi Sea, July 2007 to July 2008
Beluga calls were detected during two consecutive deployments of autonomous acoustic recorders in the northeastern Chukchi Sea. During the first deployment, calls were recorded between July and October 2007, primarily near the Barrow Canyon in July and August. During the second deployment, calls wer...
