Marine Vibrator and Blue Whales

Research Centre Húsavík

This project is funded by the German Environmental Agency and is done in collaboration with University of Hannover (Die Stiftung Tierarzliche Hochschule Hannover (Tiho)).

The overall goal is to test a marine vibrator and investigate the reactions of blue whales to load frequency sound.

First, we deployed an acoustic tag with a suction cup on the back of a blue whale. This was done in co-operation with Tom Akamatsu from Japan.

Then, we deployed a hydrophone array with four sound traps to record the underwater sound.

Finally, we play back low frequency sound with a big underwater loud-speaker from a fishing vessel. Data from the experiment is collected in a pre-trial, control and post-trial.
