Day Two...Exuberant false killer whales, humpbacks heard

3/31/2018

​Today we surveyed the open ocean while getting familiar with our new captain Chanin, and with our various equipment.

The team
​Given the expected low whale density we reduced our survey speed to 9 knots and stopped every 15-20 minutes to listen for humpback whale song. And it paid off: we heard distant song on three of our listening stations, so we know male humpbacks are engaged in courtship behavior here.

Using the hydrophone
​We also encountered a group of spotted dolphins early in the morning. But the day’s show was stolen by a large aggregation of false killer whales (Pseudorca crassidens). We first heard their loud whistles on our hydrophone and then saw their large splashes from a distance. We stayed with them for about an hour as we moved from subgroup to subgroup to collect photo-IDs. We also collected three biopsies for DNA studies.
