Audio of orcas harassing sperm whales in Bleik Canyon, northern Norway, on 23-07-2011
Description
Two-channel wav file recorded on 23-07-2011 aboard the M/S Reine, within 69.34 – 69.47 N and 15.58 – 15.86 E in the Bleik Canyon. The M/S Reine is owned and operated by Whalesafari Andenes, and Whalesafari is the originator and owner of this audio file. The M/S Reine has two custom hull-mounted directional hydrophones, sampling rate at 44.1 kHz that allow the crew to listen for cetaceans and, based on differences in loudness between the hydrophones, get close to where the animals are before they surface. Detailed information about the hydrophone specifics can be found in Nielsen & Møhl (2006). Description of the orca harassment event on sperm whales is described in Cosentino et al., in review with Marine Mammal Science Notes. Cosentino, M., Griffiths, E.T., van Dam, J., van Dongen, C.H.
