HMSC Science on Tap- Marine Debris and Microplastics in our Watersheds

Speaker: Dorthy Horn

Topic: Marine Debris and Microplastics in our Watersheds

Microplastics are present throughout coastal marine ecosystems globally. These tiny plastics (<1mm) are highly abundant within the near shore environment as well as in surface waters offshore. The presence of these microplastics poses a threat to the marine organisms within this ecosystem. Numerous laboratory studies have shown ingestion of these plastics by a wide array of organisms, from zooplankton to marine mammals, as well as their deleterious effects. Dorothy's research spans across the Oregon, California and Costa Rican coastlines, and she will discuss her findings in the sandy beach environment as well as three different species of crab. Dorothy will discuss the issues regarding marine debris, how it becomes microplastics and the impacts we see globally as well as locally here in Oregon.
