Abstract
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 were operating at a duty
cycle of 2 minutes on and 30 minutes off, sampling at 39062 Hz and recording
in 24 bits. This presentation will report the acoustic analysis done on the data
using SONS-DCL, comparing the results between the different locations and
putting emphasis on the differences in received sound levels mostly due to ice
movement, anthropogenic sources and the presence of cetaceans in the different
seasons. For the Greenland Sea data, an overview will be presented of the relationship
between received levels and distance of a detected seismic survey. As
for the animal presence it was found to be minimal during the summer months,
although sperm whales where present all year round and some fin whale calls
were received in early summer as well. Bearded seal presence was very seasonal
from around April to June both at Spitsbergen and Greenland. 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. A number of unidentified
acoustic events were detected as well. These data will be shown here, but are
also available for playback from a dedicated website.
