We had a rather uneventful day. We started regular monitoring early this morning, and had picked up some faint clicks just before daylight. However, the whales went quiet and we were not able to reacquire them later on. We heard very faint clicks again in the afternoon, but once more lost them before we could start proper tracking. Sighting conditions were not ideal for most of the day, which allowed us to sail for good parts of the day, but which did not help in making visual sightings likely. Throughout the day, we heard the distant rumbles of airguns.

The changes to the boat-mounted directional hydrophone that we made today appear to stop the pod from turning on its pole. The real test will come once we are tracking sperm whales, of course.
