Iain Kerr, CEO of the Gloucester-based Ocean Alliance, gives a public talk Wednesday called "Why Whales?" at the O'Maley Innovation Middle School auditorium in Gloucester. Kerr talked about Ocean Alliance's innovative whale research program, including the famed "SnotBot" drones used to aerially collect biological samples from the spray of whales, as well as the group's ocean conservation efforts. He explained how data collected from whales can tell us a great deal about the health of our oceans and, by extension, the health of our planet and ourselves.
