When one says they’re going to be volunteering to survey microplastics, it’s likely that most people don’t have a clue what microplastics are, and wonder why you’re surveying them. Well, to answer the question, microplastics are pieces of plastic that have photodegraded into smaller and smaller pieces. Since plastic doesn’t actually biodegrade, the plastics stay there in the ocean, imitating pieces of food for fish, birds, etc. While “nurtles” are a fun name to say, it’s not so exciting to know that these plastic pieces are harming the ecosystem. Even more disturbing is the presence of the Great Pacific Garbage Patch, where, because of the currents of the ocean, a good portion of the Earth’s trash ends up floating in this gyre, accumulating trash, debris, and plastics into an area the size of Texas.
I first heard about this phenomenon from Curtis Ebbesmeyer (I would highly recommend reading some of his work), when he came as part of the People For Puget Sound/REI Talk Series last year. So, when I found out that my former organization, the Snohomish County Marine Resources Committee, was teaming with WSU Beach Watchers, and the Port Townsend Marine Science Center, I decided to tag along with the other volunteers from Edmonds Community College.
The first day was the field day, where we would collect the samples at Mukilteo Lighthouse Park and Howarth Park. I was happy to be out in the field, and on the beach again, although it was pouring down rain, and I was drenched. By the afternoon site, the weather cleared, and it was refreshing. The process of collecting the samples was simple enough, but the analysiswas the hard part. I was in charge of sorting pieces of plastic, Styrofoam, twine, and other human-made debris out of a tray of rocks, twigs, sticks, and shells, only using tweezers and a microscope. Can you say tedious? I started going stir-crazy at the end, so I must give my special thanks to David for helping me finish my tray.
Overall, it was a great experience, and I am curious to see the results of the survey and notice any trends or differences across the sites in Puget Sound.
Anyone else want to share their experiences on the microplastics survey? How about the sand flea incident?
