Microplastics in 29 Great Lakes tributaries (2014-15)

This dataset describes the quantity and morphology of floating microplastics in 29 Great Lakes tributaries in 6 states. Samples were collected in spring 2014 – spring 2015. Each tributary was sampled three to four times, capturing low-flow and runoff-event conditions. Sampling and analysis methods are described in the .xml metadata file. These data are interpreted in a journal article (cite journal article).
