🛥️📊 These first-year undergrads spent the fall on Narragansett Bay learning boat handling, knot tying, sensor deployment, & real-time data analysis. #URIGSO students supported fieldwork, dove to retrieve instruments, and guided students through MATLAB & data interpretation for their final projects.

A recent #URIGSO-led study analyzed 23,000+ sediment samples and found a key gap in a common method for measuring carbon in salt marshes. Addressing this gap is essential for understanding marsh resilience and for guiding blue carbon strategies.

🚢 🔊 What’s it really like to live & work aboard a research vessel? In this episode of the Oceanography pod, #RVEndeavor ops manager Brendan Thornton & captain Chris Arminetti reflect on nearly 50 years of life at sea and retiring a ship with over a million miles in her wake.

The results highlight the persistence of microplastic pollution and underscore the urgency of reducing plastic inputs to coastal systems. Read more in Environmental Science and Pollution Research: buff.ly/oZp0aTc 🌊

Using sediment cores from across the Bay and Rhode Island Sound, the team found that an estimated 2,300–3,000 tonnes of microplastics have accumulated in seabed sediments over the past century. 🌊 🦑

🌊🚨 New research on #microplastics in Narragansett Bay

#URIGSO researcher Victoria Fulfer, Ph.D. ’24, and Professor J.P. Walsh have published a new study documenting exponential growth in microplastic pollution in Narragansett Bay since the 1940s.

Central to the study was a passive sampling device designed by Snook during his doctoral research while a trainee in URI’s STEEP Superfund Program. The study provides regulators with the data needed to take action to remediate PFAS contamination at its source & protect freshwater systems, long-term.

URI study identifies long-term source of PFAS contamination to Pawcatuck River Provides foundation for decision-making around remediation for sites previously identified by researchers as PFAS ‘hotspots’

Published in Environmental Science & Technology Water, the research shows that PFAS stored in pond sediments continue to migrate into the river decades after textile operations ceased, with one site potentially releasing contamination for more than 100 years without remediation.

🌊 PFAS in the Pawcatuck River: A new study led by #URIGSO alum Jarod Snook, & co-authored by members of the Lohmann Lab, has identified long-term sources of PFAS (“forever chemicals”) entering the Pawcatuck River from two historically contaminated textile mill waste ponds in Bradford & Westerly, RI.

Working alongside RI oyster farmers, Rosa collected 127 water samples, monitored carbonate chemistry linked to ocean acidification, & studied how different aquaculture gear influences oyster growth/survival. Her research offers practical insight to support the state’s growing aquaculture industry. 🌊

Our winter transect cruise is underway on the RV Armstrong. Our team will spend 5 days stitching a line across the Northeast US Shelf sampling the winter ecosystem. Fair wind & seas with mild temps for the crew! @whoi.edu @urigso.bsky.social @wellesley.edu @smast @uslter.bsky.social Thank you #nsf

With a focus on using GIS to examine the tropical coastal processes and challenges of the Bahamas, the team conducted beach and seafloor surveys, measured salinity and density in water bodies around the island, analyzed shoreline marine debris, and snorkelled the many bays and beaches they visited!

🌊 Ten URI undergraduate students spent their January term on San Salvador Island, Bahamas, as part of a class called Coastal Processes, Changes and Challenges in the Tropics, led by #URIGSO’s J.P. Walsh & Chris Damon of URI CELS Environmental Data Center (EDC).
