Noise and biological sounds: Artic soundscapes during the 2013 and 2014 seasons
Statoil deployed three acoustic recorders from fall 2013 to fall 2014 in the Arctic region as part of a broad scientific campaign. One recorder was installed in the Barents Sea southeast of Spitsbergen. Two other recorders were installed in the Greenland Sea north-east of Greenland. All recorders we...

Bowhead whale presence at Greenland was especially strong during the winter, with possible humpback presence at Spitsbergen. But no attempt was made to distinguish humpback and bowhead whale calls. At Spitsbergen belugas or narwhals were present; at the Greenland recorders there were fewer dolphin signals, and those found were most likely from white beaked dolphins.
