Data release for microplastics in water, sediment, fish, and mussels in the St. Croix National Scenic Riverway and Mississippi National River and Recreation Area, Wisconsin and Minnesota, 2015

This dataset describes the concentration and morphology of microplastics in the St. Croix National Scenic Riverway and Mississippi National River and Recreation Area, Wisconsin and Minnesota. Samples were collected during baseflow conditions at eight locations during the week of August 3-7, 2015. Four types of samples were collected: water surface, streambed sediment, smallmouth bass (Micropterus dolomieu), and threeridge mussels (Amblema plicata). Water surface samples were collected at all eight sites; other sample types were collected at only a subset of sites.
