Monday’s Wake up with the Whales Cruise was a lot of fun. We only found one whale, but he was on the surface a lot. We’d watch him spout a couple of times and then dive, only to come up 6 minutes later.
We also got to deploy the hydrophone and we heard some great sounds. The singer was so close that when we pulled the hydrophone out of the water again we realized that we could hear the sounds reverberating through the hulls — no need for fancy technology!
Captain Claire’s Humpback Fact of the Day: Since Doctors Katy and Roger Payne and associates first analyzed their recordings of the Humpback song in 1967, we’ve learned that not only does every singer in a Humpback population sing basically the same song, but that the song continually evolves. The song is very organized, and consists of notes, phrases, and themes. No one knows the true purpose for the song, but since every population of Humpbacks sings their own song, and since they mainly sing during mating season, the song may play a role in social organization.
