Estuarine Sedimentary Microplastics from City to Sea: Narragansett Bay, Rhode Island, USA
AI summary Read the abstract
This is a duplicate dataset entry for the Narragansett Bay estuarine microplastics study (same as 45413). The dataset documents microplastic concentrations and polymer types found in sediments from shoreline to offshore locations in the bay. These data support understanding of how microplastics move from urban land sources through estuaries toward the ocean.
Count and polymer characterization data for microplastics extracted from shoreline and estuarine sediments around Narragansett Bay, Rhode Island, USA. Microplastics (63µm - 5 mm) were extracted from sediment using a dense solution of sodium iodide (NaI) followed by enumeration via microscopy and polymer characterization via Fourier-transform infrared spectroscopy (FTIR)(Shimadzu IRTracer-100). Concentrations are reported in # MP particles per kg dry weight (DW) sediment.

Exponentially increasing microplastic accumulation in an urban estuary: insights from the Narragansett Bay, Rhode Island seafloor
AI summary Read the abstract
Researchers found that microplastic concentrations in Narragansett Bay sediments have increased exponentially since the 1940s, mirroring global plastic production trends, with marsh sediments accumulating microplastics at ten to fifty times higher concentrations than nearby seabed sites. An estimated 2,300 to 3,000 tonnes of microplastics have accumulated in the bay's sediments over the past century, with nearly all sampling sites now exceeding harm thresholds for benthic organisms.
Quantification of microplastics in sediments from Narragansett Bay, Rhode Island USA using a novel isolation and extraction method
AI summary Read the abstract
Researchers developed a novel microplastic extraction method using sodium bromide density separation for sediments from Narragansett Bay, Rhode Island, achieving high recovery rates for particles in the 45-1000 µm size range and quantifying microplastic abundance and polymer composition across multiple sampling sites.
Comparing field-based microplastic observations with ocean circulation model outputs in estuarine surface waters along a human population gradient
AI summary Read the abstract
Researchers compared field-collected microplastic data with ocean circulation model simulations in Narragansett Bay, the largest estuary in New England. They found higher microplastic concentrations in urbanized northern areas compared to less populated southern regions, with significant temporal variability driven by weather and tides. The study suggests that ocean models can capture broad microplastic movement trends, but fine-scale accuracy remains limited.
