Summary

This dataset describes the quantity, morphology, and polymer identity of microplastics in the water column and surficial sediments of Milwaukee-Area streams, the Milwaukee Harbor, and Lake Michigan (Wisconsin). Water samples were collected at 10 locations, 2-4 times each, from May to September, 2016. At the 4 shallowest locations, water was collected only at the water surface. At the remaining 6 locations, water was collected at the water surface and at 1-4 depths below the surface. Sediment samples were collected once, in June 2016, at a subset of 9 locations. Sampling and analysis methods are described in the Processing Steps section of the metadata. These data are interpreted in a journal article (TBD).

Purpose

These data were obtained in order to assess the variability in the vertical distribution of microplastics in the water column and sediment from stream to estuary to lake. Understanding the vertical distribution of microplastics is critical to estimating loads. Previous studies have generally sampled only the water surface, potentially over- or under-estimating the quantity of microplastics present. This study was funded by the Milwaukee Metropolitan Sewerage District and the USGS Cooperative Matching Funds Program.
