We drifted with Olympia and Fissure for about 20 minutes and things were pretty quiet. The two whales would dive for 7 or 8 minutes, then come up and blow a few times and dive again. We suspected they were feeding, perhaps cooperatively since the stayed near each other and come up at the same time.
Suddenly Olympia slapped her tail on the surface of the water with an explosive whack! It was a total surprise and all we could figure was she was alerting Fissure (or us?) that she had had enough and was heading off to feed.
