Do you wonder what is swimming out there in our sea waters—with or without you?

The DMFTalk “Who is Swimming in Our Ocean? Great White Sharks and Others” answered the question with the focus on great white sharks as well as other sea creatures that share the territory, so to speak. This always fascinating topic was brought to life by the team of Dr. Heidi Dewar and Nicole Nasby-Lucas. Together they spoke about who makes our local ocean home and how they find out. Dr. Dewar’s focus is on the development and application of electronic tagging technologies to better understand fish in their natural environment—from Manta rays to billfish, tunas and sharks. She studies the movements and behaviors of fish. Nasby-Lucas studies the migration and habitat of fish and great white sharks. She talked about her focus of producing a database of sharks at Guadalupe Island, Mexico where she monitors the patterns of individual sharks and tracks the overall status of the population.

Dr. Dewar works with the team at the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center, that researches highly migratory species collecting biological data in support of management. She received her BA in Biology from Oregon State University and her PhD in Marine Biology from Scripps Institution of Oceanography.

Nicole Nasby-Lucas is a Research Biologist with the Marine Conservation Science Institute. She earned her BA in Biology at St. Olaf College, Northfield, MN and her MS in Marine Resources Management from Oregon State University, College of Oceanic and Atmospheric Sciences.
