Antarctic blue whales in the southern Indian Ocean: a multi-year and multi-site database of Z-call detections ...
As part of the OHASISBIO project, since January 2010, a network of 6 to 8 autonomous hydrophones is deployed in the southern Indian Ocean (Fig. 1) to monitor the low-frequency sounds (0-120 Hz) carried by the ocean. These acoustic data provide unique information on the seasonal presence of several s...
