Movement and impacts of #microplastics in coastal ecosystems.

[Coleen Suckling @echinonerd]

Please share! We’re recruiting a PhD student to study microplastic presence, distribution & impacts in Rhode Island, USA. Join a large, collaborative, statewide capacity-building project funded by #NSF. 🌊🔬 https://t.co/xxzDV1UAIP

This weekend I graduated with my PhD from the University of Rhode Island! Very grateful for the mentorship of my advisors, Coleen Suckling and Andy Davies, and looking forward to continuing to research emerging environmental contaminants as an ORISE postdoc fellow at the US EPA

[Coleen Suckling @echinonerd]

Congratulations to @sdavisplastics for passing the Doctoral Defense! So proud of all that you’ve achieved on understanding microplastic pollution presence & impacts! #Echinonerdlab @universityofri @uricels @rhodeislandsg

@TampaElectric My parents are still without power and the outage keeps disappearing from the map despite reporting it constantly.

@victoria_fulfer @universityofri @URIGradSchool @5gyres @URIGSO Congratulations Victoria!! Can’t wait to see what you accomplish next

[Sarah Davis, PhD @sdavisplastics]

Excited to be representing @universityofri this Friday at the Northeastern Association of Graduate School's 3-Minute Thesis regional competition! If you like #microplastics and/or #crabs...tune in!

Our amazing Coastal and Environmental Fellow Lindsey built a model rack of humpback baleen and tested to see what shapes/sizes of #microplastics might be retained during filter feeding. Go Lindsey!! #oceanplastic #womeninscience

[Sarah Davis, PhD @sdavisplastics]

Our awesome summer fellow Lindsey imaging some humpback whale baleen for an exploratory project on #microplastics and mysticete filter feeding!

[Rhode Island EPSCoR @RIEPSCoR]

A big month for RI EPSCoR! First, NSF Director @DrPanch reviewed our #research & broader #impacts, and last week, investigators presented at the 2023 Global Plastics Forum @universityofri. More on their efforts tackling the #plastics problem: https://t.co/qOvqLudvgi @URIPlastics

This experimental study's goal is to better understand the vulnerability or resiliency of Jonah crab to the impacts of microfiber ingestion after consuming filter-feeding bivalves, like oysters or mussels. @rhodeislandsg @RIEPSCoR @uricels

[URI Graduate School of Oceanography @URIGSO]

#JonahCrab is a quickly growing commercial species, with RI landings accounting for about 25% of the total US harvest. However, the influence of anthropogenic pollutants on Jonah crabs, especially #microplastics & #microfibers, may present a threat to population productivity.

[URI Graduate School of Oceanography @URIGSO]

Sarah Davis (@sdavisplastics), PhD student in @echinonerd & #URIGSO's @anddavies labs, recently put 60 Jonah crabs in the mesocosm tanks at the @universityofri Bay Campus to better understand the movement of #plastics through coastal food webs. #microplastics

[Sarah Davis, PhD @sdavisplastics]

Aaaaand we're off! 60 Jonah crabs in the @URIGSO mesocosm tanks to assess their interactions with #polyester #microfibers through predation of bivalves. #microplastics #marinescience #phdlife

[Sarah Davis, PhD @sdavisplastics]

@SeaWayward @URIGSO the sediment trays from the last two years of experiments were removed in the fall! There is however a layer of unofficial mud at the bottom of the tanks still.

[Sarah Davis, PhD @sdavisplastics]

A pretty satisfying before and after deep cleaning the #mesocosm facilities at @URIGSO - almost experiment ready!

[Sarah Davis, PhD @sdavisplastics]

Kicked off an experiment yesterday to investigate short-term digestive behavior of Jonah crabs fed oysters inoculated with polyester microfibers!! Long couple days in the lab. Send snacks... #crabirrigationsystem #microplastics #plasticpollution #phdlife

[Sarah Davis, PhD @sdavisplastics]

For our upcoming mesocosm experiments, we're working on creating a more naturalistic food stock (in this case, whole oysters) containing controlled doses of spike plastics for crab exposure trials! #microplastics #plasticpollution #trophictransfer #jonahcrabs

[Sarah Davis, PhD @sdavisplastics]

Thank YOU for joining us and giving such an engaging and informative talk! Looking forward to hearing more about your fascinating research as it progresses!!

[Dr. Michaela Cashman @EnviroMichaela]

Thanks so much to @sdavisplastics and @echinonerd for hosting me today at the URI BES seminar. It was fantastic to return to my alma mater and talk about PFAS.
