Rammed by a sperm whale?

Our paper was recently published in Aquatic Mammals in which we describe our encounter with a group of sperm whales near the Mariana's Islands. We were conducting a line transect survey in the general area at the time, however, at the time of the incident we were traveling at less than 4 knots. You can read the article here. You can also watch a video of the encounter here. My photo made the cover of the journal!
