Plankton of the Salish Sea: the basis of the food chain – Chandler Colahan, Educator, Padilla Bay National Estuarine Research Reserve
Class Description: Though we all love the colorful sea stars and frolicking otters, it’s the tiny world below that keeps our Salish Sea ticking. Learn about the hidden majority of life that flourishes in our local waters and beyond. In this recorded talk, we explore the secret world of plankton and look at how these microscopic organisms play vital roles in the ecosystems of the Salish Sea.
Speaker: Chandler Colahan is the education specialist at Padilla Bay National Estuarine Research Reserve in Bayview, WA. She has been an environmental and marine educator for more than twenty years. Chandler has a BA degree in Ocean Science, Education, and Creative Expression from Western Washington University, Fairhaven College. She also spent many years researching plankton and jellyfish at Shannon Point Marine Center. When she is not exploring the mudflats with students, you can often find Chandler exploring the waters of the Salish Sea looking for wildlife.

- The Secret Life of Plankton – Approx 6 minutes video. New videography techniques have opened up the oceans’ microscopic ecosystem, revealing it to be both mesmerizingly beautiful and astoundingly complex. Marine biologist Tierney Thys created a film to ignite wonder and curiosity about this hidden world that underpins our own food chain.
