Summary
Researchers documented the proportion of microplastics by morphological shape — fiber, fragment, and sphere — across 11 sites in the St. Lawrence River and Estuary using 300 µm and 100 µm mesh nets, comparing distributions from upstream to downstream. The dataset illustrates spatial variation in microplastic shape composition across fluvial and estuarine environments.
300 µm and B. 100 µm mesh size across all sites. Left to right: upstream to downstream; sites 1 to 11.
