Dr. Costa is currently a Professor of Ecology and Evolutionary Biology at the University of California at Santa Cruz. He has specialized on the physiological and ecological studies of marine mammals and seabirds for the last 33 years. He has extensive experience both in the lab and field with a large number of marine mammals and seabirds including wandering, black browed and gray headed albatrosses, Chinstrap, adelie and king penguins, sea otters, bottlenose dolphins, California, Galapagos, Australian and Steller sea lions, Antarctic, northern, Galapagos, Australian New Zealand fur seals and on elephant, harbor, and Weddell seals. He has extensive experience with the deployment of electronic tags on marine mammals and seabirds, having been involved in the development time depth recorders using both photographic and electronic methods since 1978. He was involved in the first deployment of time depth recorders on Weddell seals in 1978-79 and on elephant seals in 1983.
