In this episode of the American Blue Economy Podcast, our host Rear Admiral, Tim Gallaudet, PhD, US Navy (ret) interviews Dr. Kate Musemeche to discuss her book Lethal Tides: Mary Sears and the Marine Scientists Who Helped Win World War II. Drawing on prior episodes that explored the influence of the U.S. Navy and oceanography on the blue economy, we examine how ocean science and blue tech have helped the U.S. Navy, and that many spinoffs from this contribute to our ocean and coastal economies. This is a special show in that Rear Admiral Gallaudet, as a former Oceanographer of the Navy, uncovers in Dr. Musemech's book the story of the very first Oceanographer of the Navy in modern times, a Navy WAVE Lieutenant Junior Grade named Mary Sears. The show also highlights the wartime contributions of Scripps Institute of Oceanography and Woods Hole Oceanographic Institution, whose representatives have been on several prior episodes. If you want to see how the marine science that supports the blue economy also contributes to national security, check it out!
