Temperature and geophysical data collected along the Quashnet River, Mashpee/Falmouth MA

The temperature and surface geophysical data contained in this release have primarily been collected to support groundwater/surface water methods development, and to characterize the hydrogeological controls on native brook trout habitat. All data have been collected since 2010 along the Quashnet River corridor located on Cape Cod, MA, USA. Cape Cod is a peninsula in southeastern coastal

Bathymetric survey data from the Deschutes River near Bend, OR, July 25, 2016

The U.S. Geological Survey conducted a bathymetric survey of a reach of the Deschutes River near Bend, OR, between Benham Falls and Dillon Falls on July 25, 2016, to support research on remote sensing of river discharge and characterization of habitat for amphibians, particularly the Oregon Spotted Frog. The bathymetric survey data were obtained with an ITER Systems Bathyswath-1 468 kH

Disentangling the effects of low pH and metal mixture toxicity on macroinvertebrate diversity: data sets

This dataset is comprised of water quality data and benthic macroinvertebrate data collected from basins in Colorado, USA, and Finland. The data includes ancillary water quality characteristics but also a suite of trace metals observed at each site. Also included are modeled outputs that characterize the bioavailability of each trace metal to a biotic ligand. These data were used to explore t...

MODFLOW-NWT model data sets used to evaluate changes in the hydrodynamics of Anvil Lake, Wisconsin

A MODFLOW-NWT groundwater flow model was developed to simulate groundwater
movement in the area around Anvil Lake, and groundwater inputs and outputs from
the lake from 1980 to 2014. Surface-water hydrology was simulated using the lake
package. The MODFLOW model was first calibrated for steady-state conditions, or
"average" conditions corresponding to January 1, 1980,...

Total mercury, bulk density, percent organic matter, and percent organic carbon measured in permafrost cores collected from 2004 through 2012 from the interior and northern slope of Alaska

The "MasterDB-csv-final2" dataset includes 548 laboratory measurements of sediment total mercury (STHg, nanograms per gram of soil, dry), bulk density (BD, grams per cm3 of soil, dry), percent of soil organic matter (%OM, loss on ignition, LOI), percent of soil organic carbon (%SOC, calculated using the Redfield's number), RHgC (Hg to carbon ratio

Hyperspectral image data acquired during a tracer dye experiment on the Kootenai River, ID, September 27, 2017

To support research on dispersion in river channels, a tracer dye experiment was performed on the Kootenai River in northern Idaho, September 25-27, 2017. This data release provides access to hyperspectral image acquired during the experiment and the supporting field-based measurements of reflectance and dye concentration are available through related data releases. The hyperspectral image...

Chloropyron maritimum subsp. maritimum population counts, tide, and weather data for Sweetwater Marsh National Wildlife Refuge

Chloropyron maritimum subsp. maritimum population counts at Sweetwater Marsh National Wildlife Refuge, California, and tide and weather data from San Diego, California, are used to explain interannual variation in Chloropyron counts and to predict past population counts.

Water quality, quantity, and gas fluxes of the Upper Mississippi River basin (WY 2012-2016)

This product consists of one tabular dataset and associated metadata of water quality information related to rivers, streams, and reservoirs in the Upper Mississippi River watershed between 2012 and 2016. This data release is apart of a national assessment of freshwater aquatic carbon fluxes. Data consist of organic and inorganic carbon related species, carbon dioxide and methane gas fluxes...

Methane and nitrous oxide temporal and spatial concentrations in the Iroquois River and Sugar Creek in Northwestern Indiana and Northeastern Illinois, 1999-2003.

A comprehensive study of water quality in two streams was conducted in the Midwestern United States in 1999 to 2003. The Iroquois River and Sugar Creek, located in northwestern Indiana and northeastern Illinois have been heavily impacted by agricultural land use and contain relatively high concentrations of inorganic nitrogen, primarily as nitrate. As part of that study, samples were coll...

Data Release for Metamodeling and Mapping of Nitrate Flux in the Unsaturated Zone and Groundwater, Wisconsin, USA

Widespread nitrate contamination of groundwater in agricultural areas poses a major challenge to sustainable water resources. Efficient analysis of nitrate fluxes across large regions also remains difficult. This study introduces a method of characterizing nitrate transport processes continuously across regional unsaturated zones and groundwater based on surrogate, machine-learning metamodels...

MODFLOW-2005 used to evaluate the effects of withdrawals from two aquifers in the New Jersey Coastal Plain for Cumberland County and vicinity, New Jersey

A local and a regional groundwater-flow model were used to evaluate the effects of
withdrawals in Cumberland County and vicinity in New Jersey. The local model
simulated monthly groundwater withdrawals from the unconfined Kirkwood-Cohansey
aquifer system and surface-water diversions from 1997 to 2008. The regional model,
the New Jersey Coastal Plain RASA model,...

Phytoplankton Species Composition, Abundance and Cell Size in San Francisco Bay: Microscopic Analyses of USGS Samples, beginning in 2014

This Data Release makes available measurements of phytoplankton species composition, abundance and cell size made on samples collected in San Francisco Bay (CA) from January 2014 through December 2016. Whole water phytoplankton samples were collected at least monthly at fixed sampling stations along a 145-km transect where the variability of salinity, temperature, turbidity and nutrient...
