Episode 1101: The Cordell Bank: A National Treasure
California’s north-central coast is famous for its natural splendor. Only fifty miles northwest of San Francisco’s Golden Gate Bridge, yet light years away from the hustle and bustle of the human world, lies a magical underwater island few people have ever heard of. Protected inside a National Marine Sanctuary, the Cordell Bank is a hotspot for marine life. Cold, nutrient-rich waters welling up from the deep fuel the base of the marine food chain in the region, which in turn feeds birds, sea turtles, and marine mammals who travel from thousands of miles away.
And while the sanctuary is actively protecting local resources, it still faces global stressors that might threaten the area in the future. Scientists are studying the potential impacts of ocean acidification and lowered dissolved oxygen levels caused by climate change.
Meet the experts featured in this episode.
