The Kelp Crisis and the Miracle of Macroalgae

In the latest episode of Changing Waters, Global Ocean Health’s Deputy Director Julia Sanders interviews kelp guru, Dr. Tom Mumford from the Friday Harbor Laboratories, University of Washington in Seattle. From Northern California to Southern Oregon, kelp is undergoing devastating losses, with 95% of kelp forests turned into urchin barrens. Tom explains what happened and the miraculous benefits kelp provides as an ecosystem engineer and as a source for new scientific discoveries. From kelp-derived plastic you can eat, to wound care, from rediscovering how kelp can help farmers, to a critical contributor to biodiversity and marine food webs, there is much to be gained from kelp. Catch this episode of Changing Waters and open your eyes to a miracle macroalgae and the struggle to keep it thriving in changing ocean conditions. Only on the American Shoreline Podcast Network.



Director of the Scripps Institute of Oceanography, Dr. Margaret Leinen

On this episode, host and NFCC Director Brad Warren sits down with Dr. Margaret Leinen, the Director of the Scripps Institute of Oceanography. Margaret Leinen, a highly distinguished national leader and oceanographer, was appointed the eleventh director of Scripps Institute of Oceanography at UC San Diego in July 2013. She also serves as UC San Diego’s vice chancellor for marine sciences and dean of the School of Marine Sciences. She joined UC San Diego in October 2013.

Leinen is an award-winning oceanographer and an accomplished executive with extensive national and international experience in ocean science, global climate and environmental issues, federal research administration, and non-profit startups. She is a researcher in paleo-oceanography and paleo-climatology. Her work focuses on ocean sediments and their relationship to global biogeochemical cycles and the history of Earth’s ocean and climate.



Former President of Ireland, Mary Robinson

Welcome to the Changing Waters podcast, a new NFCC show in partnership with the American Shoreline Podcast Network about the ocean, the people who depend on it, and the people who are working to keep it healthy. On this special inaugural episode we are treated to a conversation with the former President of Ireland, Mary Robinson, a self-proclaimed climate justice activist.

The interview is conducted by Camorah King, a graduate student at the Middlebury Institute of International Studies


Dr. Ray Hilborn on Fisheries

On this episode of Changing Waters, host Brad Warren sits down with Dr. Ray Hilborn, a marine biologist and fisheries scientist, known for his work on conservation and natural resource management in the context of fisheries. He is currently professor of aquatic and fishery science at the University of Washington. He focuses on conservation, natural resource management, fisheries stock assessment and risk analysis, and advises several international fisheries commissions and agencies. Dr Hilborn is a Fellow of the American Academy of Arts and Sciences and widely published.


Killer Whales and the Food Web with NOAA Researcher Laurie Weitkamp

In the first of Changing Waters’ series on the plight of southern resident killer whales, National Fisheries Conservation Center’s Deputy Director Julia Sanders interviews NOAA researcher Laurie Weitkamp about the food web effects caused by recent heat waves in the Pacific ocean, including the “warm blob.” These changing conditions have caused major disturbances all the way up the food web: starting with microscopic plankton and ending with our beloved Orca whales. Learn more about what’s happening in our changing waters as temperatures rise and fisheries face abrupt disruptions — including the Chinook salmon that southern resident killer whales rely on.
