A program by the Technical University of Catalonia lets researchers study the effects of human activity on whales and dolphins.

A fascinating project from Michel André, a bioacoustician at the Technical University of Catalonia, allows listeners around the world to hear the sounds coming from the deep sea. Whales, ships, and other human and natural activity can be heard courtesy of 10 hydrophones located around Europe and Canada.

New Scientist reports:

The network’s primary aim is to record and archive long-term subsea noise so that researchers can study the effects of human activity on whales and dolphins.

…An algorithm developed by André’s laboratory filters the different frequencies in the signal to identify specific sounds, including the songs of 26 species of whales and dolphins, and noise from human activities such as shipping, wind farms, oil and gas drilling, and seismic testing.
