Abstract
The automated acoustic detection of cetaceans in real time is an important
tool to study their behaviour and distribution and for activating mitigation
measures in the context of harmful anthropogenic activities at sea. Acoustic data
from the NEMO ONDE deep sea observatory (Sicily) indicated that sperm whale
clicks were present in 15 % of the recordings and impulsive ship noise in 10 %. The
ship noise poses a serious challenge to the detection of sperm whale clicks, since it is
an important source of false positives. As part of an integrated classification system,
we present a classification module aimed at the automated and real time classification
of impulses from sperm whales and shipping. The achieved classification
performance indicates that it reliably separates a large proportion of sperm whale
clicks from shipping impulses.
