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.
