Divemaster Emily Callahan was born on a small island off the coast of New Hampshire. She is an oceanographer, dive master and environmental scientist. In 2011 she worked in the Gulf of Mexico on the Deepwater Horizon oil spill. Her work in the Gulf analyzing the oil spill, and the development of the oil and gas industry sparked her research interest in the Rigs-to-Reefs program, from which has stemmed the creation of her non-profit Blue Latitudes, an organization that investigates implementing the Rigs-to-Reefs program in California. Emily has a master’s in Marine Biodiversity and Conservation from Scripps Institution of Oceanography, and is currently a project scientist for an oceanographic and engineering consulting firm. Emily comes from a family of divers and has been diving since the age of 12, she has traveled around the world pursuing this passion and is thrilled to be a member of the SD Expeditions team.
