I attended and presented my work on how microplastics impact the benthic-pelagic coupling role of marine mussels in February in San Diego, CA. This conference was by far the largest one I have been too. I presented in one of three(!) sessions focusing on microplastics, also a new experience for me.
I attended and presented my research at AAAS February in Seattle. The format was an E-Poster, something I have never made nor presented before. It was good practice to figure out how my entire dissertation fits together in one, VERY short, 7min presentation.
I participated as an invited speaker for the 2020 Action Network Speaker Series on plastic. I had the opportunity to teach 3rd graders at Chautauqua Elementary School on Vashon Island about marine biology, how different marine organisms ingest microplastics, and how microplastics can pass through different ocean habitats and trophic levels.
The 3rd graders were several decades younger than my usual audience and it was a fun challenge to create a single interactive & hands-on activity that spanned multiple concepts. Some students acted out roles as orcas and sea lions while others were worms and mussels. I’ll let you guess which animals they were more excited by!
This year, WSN was held in Ensenada, Mexico. On the beach. Needless to say, it was a wonderful “work” trip. I earned Best Student Presentation for Community/Ecosystem Ecology!!
I took advantage of the wonderful and warm location to travel down there early to get some beach and ocean time in. On Halloween, a group of us (6, never met before, all there for WSN) went SCUBA diving at two boat-access sites. It. Was. Phenomenal. Diving this trip, I was able to experience a lot of “firsts” — I dove in a kelp forest, saw mussels [pooping] underwater, and a sea hare! I even got to swim with my study system!
I presented my work on at Second Chance Brewery on quantifying microplastic contamination in the San Diego watersheds. Over the past few months I have been digesting, sorting, and analyzing microplastics from my trip to the San Diego region in May. Broadly, I found microplastic contamination differed between site both in quantity as well as type. Volcan Mountain Foundation, San Dieguito River Valley Conservency, and San Diego River Park Foundation did a phenomenal job attracting participants. Below is the abstract from my talk.
Title: Mciroplastic contamination across an urban gradient in the San Diego and San Dieguito watersheds
The Volcan Mountain Range Watershed is a key water source for San Diego and its water flows directly to the Pacific Ocean. It is vital to understand how the presence of microplastic in mountain watersheds can alter the dependent downstream communities. Over a long weekend in May (2019) Lyda travelled to Julien, CA to test microplastic contamination in the San Diego and San Dieguito watersheds. Over the course of her stay in Julien she drove 600 miles along twisting roads to access different points along the rivers. While there, Lyda met several volunteers that helped me sample water in eight different sites across the two watersheds, including the headwaters (in the mountains) and mouths (Pacific ocean) of both rivers. Through citizen science and outreach, participants received hands on experience with biology and pollution science. There were meaningful discussions with both local populations and urban communities about working collectively to find sustainable solutions to anthropogenic pollutants. In addition to watershed samples, tap water was also sampled to get an idea of human ingestion levels in the area. Back in Seattle, Lyda fully processed the samples, identified plastics under a microscope, and characterized types of debris. Facilitating discussions with local community members creates more environmentally aware populations and future generations, which in turn will create policies and behaviors that foster better stewardship of our resources.
My research on mussels and microplastics is featured in this month’s (October 2019) UW Arts & Sciences Newsletter! Read about it at the link below. The pictures are a great representation of how I spend my time– in the field, in the lab, and taking selfies with massive mussels.
My new paper about microplastics and mussel clearance rate was published today! Check it out in a special issue about microplastics in Limnology and Oceanography.
If you would like to read the full paper, it is open access and can be found here:
I presented my research at PCSGA in Portland, Oregon in September on analyzing microplastic contamination in the Salish Sea across an urban gradient. My research spans public, private, and tribal lands across Western Washington. It was wonderful to meet other members of the community, especially rad women working on shellfish!
In September we spent one week at Friday Harbor Labs collecting data on mussel poop and microplastics. I was lucky enough to bring three undergrads from University of Washington with me and share my love of marine biology and experiments.
Our week in numbers: In total, we worked over 300 hours, completed 132 trials (with 4 parts each), played 18 holes of disc golf, and learned 1 or 2 things about mussels and microplastics.
“Wait, I’m making my last poop measurement. Then we can go disc golfing”
“You’re such a good pooper!”
“Can I just leave my poops lying around while we are gone?”

In May (2019) I headed out to Tatoosh Island to collect mussels for five more sites. More importantly, I headed out to help one of my my old undergrad advisors, Dr. Tim Wootton, with some miscellaneous things on the island, mainly be a 3rd person to carry everything up the stairs. Lucky for me, it is a beautiful place and rich in ecological history.
Tatoosh Island is a historical place for marine ecology. The island is located in the Makah Nation off the coast of NW Washington state. It is <0.5 square miles, and home to animals like otters, mussels, sea stars and researchers during summer months! Tatoosh is the birthplace of “Keystone Species” (coined by Dr. Robert Paine) and has some of the longest lasting data series in the world. It was a joy to revisit a place a called home for a summer and get back in the field.
I collected mussels from five historic sites on Tatoosh to quantify microplastic contamination on a fine scale. I am currently analyzing the mussels and microplastics now!
Tatoosh is in a unique location where currents converge and is a refuge to animals. Similarly, it also acts as a refuge to floating trash! While out there I noticed a large amount of trash accumulated on the beaches– I spent my free time cleaning it up. I now have several bags of “Tatoosh Trash” in the lab that are waiting to be quantified!
