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 the following journal article:...

Description of Work In 2014-15 the U.S. Geological Survey and State University of New York at Fredonia characterized the quantity and morphology of floating microplastics in 29 Great Lakes tributaries in 6 states under different hydrologic conditions, wastewater effluent contributions, land uses, and seasons. Tributaries were sampled four times each, during high-flow and low-flow conditions. Samples were collected from the upper 20-30cm of the stream using a 0.33mm mesh neuston net. Microplastic particles were sorted by size, counted, and categorized as fibers/lines, pellets/beads, foams, films, and fragments. References 1. R. C. Thompson et al., Lost at Sea: Where Is All the Plastic? Science. 304, 838 (2004)....

This dataset describes the quantity and morphology of microplastics in water, sediment, fish, and mussel samples from the Delaware River and select tributaries, including portions of the Upper Delaware Scenic & Recreational River, Middle Delaware National Scenic River, Delaware Water Gap National Recreation Area, and Lower Delaware Scenic & Recreational River. Water and sediment samples were collected at nine locations, from Callicoon, New York, at the upstream end, to Burlington, New Jersey, at the downstream end. Smallmouth bass (Micropterus dolomieu), white sucker (Catostomus commersonii), and eastern elliptio (Elliptio complanata) were sampled at a subset of locations to assess biological uptake of microplastics....

This dataset describes the quantity and morphology of microplastics in water, surficial sediment, sediment core, fish, and shellfish samples from Lake Mead National Recreation Area (Nevada/Arizona). Water and surficial sediment samples were collected once at 9 locations. A sediment core (33 cm long) was extracted from Las Vegas Bay to assess changes in microplastic deposition over time. Striped bass (Morone saxatilis), common carp (Cyprinus carpio), quagga mussels (Dreissena bugensis), and Asian clams (Corbicula fluminea) were sampled at a subset of locations to assess biological uptake of microplastics. Sampling and analysis methods are described in the Processing Steps section of the metadata. All samples were...

Water Quality,
These data were collected to characterize the quantity and quality of microplastic particles found in 17 streams in the northeastern United States, from New York to Virginia. USGS staff who represent the Urban Landscapes Capabilities Team (ULCT) within the North Atlantic-Appalachian Region designed the study and collected the water samples on which the data are based. Data were collected during 2017 and 2018 and included a baseflow and stormflow sample at each site. Additionally, the various microplastic particles in each sample were characterized by one of two different size-fraction categories (categories of 355-1000 micrometers and 1000-5600 micrometers), by type of particle (fiber/line, fiber clump, bead/pellet,...
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: Baldwin, A.K., Corsi, S.R., and Mason, S.A., 2016, Plastic debris in 29 Great Lakes tributaries: Relations to watershed attributes and hydrology: Environmental Science and Technology, v. 50, no. 19, p. 10377–10385, doi:10.1021/acs.est.6b02917.
Our mission is to provide , timely, reliable, impartial scientific information to our local, state, tribal, and federal partners so they can efficiently manage the water resources within their jurisdictions. Our data and research also help to protect the citizens of Idaho against floods, droughts, and other natural hydrologic hazards. Our science focuses on four basic areas of data collection and research: Surface water resources including rivers, lakes, and reservoirs Groundwater resources, both cold water and geothermal Water quality Water use and availability
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.

This release includes all data collected in support of a juvenile Chinook salmon exposure study designed to understand the retention of microplastic clothing fibers (hereon refered to as "microfibers") after feeding. To understand the potential impacts of microfiber ingestion to fish, we ran a feeding experiment with juvenile Chinook salmon to determine if ingested fibers are retained and/or digestion rates altered over a full, experimentally determined, 10 day digestion period. Data includes: fish weights, microfiber counts, and quality assurance (QA) data for the experiment. QA steps are detailed in the process section of the metadata.
