This is an edited version of an interview with Sean Todd that was first heard in episode 72 in July 2020. Sean serves on the marine science faculty at College of the Atlantic in Bar Harbor, Maine, and he’s also the director of Allied Whale, the college’s marine mammal research program. Mount Desert Rock, more than 20 miles from the nearest port and home to a historic light station, serves as Allied Whale’s research station. The former keeper’s house has accommodations for 20 students.

Sean also acts as a professional guide, including many seasons in the Antarctic. He created, wrote and starred in the award-winning “Life in the World’s Oceans,” a 30-part DVD series available from TheGreatCourses.com.
