The big problems caused by tiny pieces of plastic will be under the microscope when the Lower Nehalem Watershed Council Speaker Series welcomes Portland State University PhD candidate Dorothy Horn to the Oregon Coast on Thursday, Oct. 10

In a presentation titled “Marine Debris and Microplastics in our Watersheds” Horn will discuss the overall problems with marine debris on coastal ecosystems. This will include a discussion of her research focused on the impacts of microplastics on invertebrates in Oregon and some potential solutions to the problem.

Horn grew up in southern California going to the beach every weekend with her family. After high school she joined the Marine Corps and trained as a helicopter crew chief. On returning from the marines she finished her bachelor’s degree in Environmental Science and Biology at California State University — Channel Islands where she began her research on microplastics. In 2017, she began her PhD in Marine Ecology at PSU. She is currently funded with a fellowship from the National Science Foundation to investigate what happens to crabs and fish when they ingest microplastics. She has pursued her marine debris investigations along the coasts of Oregon, California, the California Channel Islands, Hawaii and Costa Rica.

The presentation will start at 7 pm at the Pine Grove Community House, 225 Laneda Avenue in Manzanita, preceded by a meeting of the Lower Nehalem Watershed Council’s board of directors at 5 pm.
