A Welcomed Surprise

Today my classmates and I were heading into Mitchell Bay after our first full day at sea when our Captain, Todd Shuster, noticed a collection of whale watching boats off in the distance. We took the opportunity to turn around and were rewarded by seeing a group of transient killer whales by Sidney Island. There was one male orca, which we later identified as T40, with four females or juveniles. We have not identified the other four whales yet. Males are typically easier to identify because they have larger dorsal fins, but T40 is especially easy to pick out because the tip of his dorsal fin is bent over.

It was a very exciting hour watching the whales and the boats around them. A few times the whales took a view of the world above them by spy hopping and jumped into the air a couple of times as well. After the initial exhilaration, we began to confer about the behavioral state of the whales. We were unable to deploy the hydrophones in time to record any sounds. It was a good learning experience to enable us to be more proficient in organizing equipment so that next time we come across whales we will be able to record all forms of data.  I feel fortunate that on our first full day at sea we came across orcas.

Transient killer whales on our first day

Jones Island to whales to Snug Harbor

Students raised the main sail for the first time on the Green Gato, and we sailed slowly from Jones Island to the beginning of Spieden channel. There the wind died, so we started motoring to Roche Harbor, where Val sped off to shore in the dinghy. We continued motoring towards Mitchell Bay and caught the wind for a while. When Todd noticed a little cluster of whale watching boats in Canada, we motored over to check it out. There they were — orcas — on the first full day at sea! Wahoo!

The whales we encountered were transients (the male T40 with four females) and they were frolicking and porpoising with glee. We stayed with them for about an hour, recording behavior and boat numbers. They started traveling north and we lost ’em. We motored back to Mitchell Bay, deploying the hydrophone as a demo on the way. We moored in the sunshine for an evening of swimming, burritos, and Grimm fairytales. -hmm.
