MODFLOW-2005 model archive for simulation of zones of groundwater contribution to wells south of the Naval Weapons Industrial Reserve Plant in Bethpage, New York

A groundwater-flow model was used to simulate zones of contribution to wells
south of Naval Weapons Industrial Reserve Plant, Bethpage, New York. The
model results will be used to demonstrate how the size and shape of zones
of contribution may vary.

Soil-Water Balance model datasets used to estimate groundwater recharge in Florida and parts of Georgia, Alabama, and South Carolina, 1895-2010

A soil-water balance model (SWB) was developed to estimate potential recharge and
irrigation water demand from the groundwater flow system in Florida and parts of Georgia,
Alabama, and South Carolina for the period 1895 through 2010. This SWB model executable

Digital aerial photography 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 digital aerial photography acquired during the experiment and the supporting field-based measurements of reflectance and dye concentration are available through related data releases. The digital aeri...

MODFLOW-2000 and MODPATH model data sets used in scenarios of groundwater flow and pumping (1900-2500) near Mount Pleasant, South Carolina

An existing three-dimensional model (MODFLOW-2000) by Fine, Petkewich, and Campbell (2017)
(https://doi.org/10.3133/sir20175128) was used to evaluate 7 water-management scenarios and
predict the effects on the groundwater flow and groundwater-level conditions in the Mount Pleasant,
South Carolina area. This model was...

Metabolism estimates for 356 U.S. rivers (2007-2017): 4. Model inputs

This dataset provides input data formatted for use in estimating metabolism. The format is tables of prepared time series inputs (1 tab-delimited file per site, in 1 zip file per site). This dataset is part of a larger data release of metabolism model inputs and outputs for 356 streams and rivers across the United States (https://doi.org/10.5066/...

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...

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

Annual Streamflow Sensitivity to Air Temperature for 2,673 Gaged River Basins Worldwide

This is the second of two datasets containing derived data necessary to reproduce the results of the associated journal article: "On the Sensitivity of Annual Streamflow to Air Temperature," intended for publication in Water Resources Research. The first dataset contains monthly time series of basin-mean precipitation, air temperature, and net radiation, along with basin characteris

Soil-Water Balance model datasets used to estimate groundwater recharge in Florida and parts of Georgia, Alabama, and South Carolina, 1995-2010

A soil-water balance model (SWB) was developed to estimate recharge to the groundwater flow system in Florida
and parts of Georgia, Alabama, and South Carolina for the period 1995 through 2010. The model was not calibrated;
however, various water budget components from the model output compared reasonably well with other estimates.
The model was used to estimate recharge...

Tables and charts for isotope-abundance variations and atomic weights of selected elements: 2016 (Ver. 1.1, May 2018)

Twelve chemical elements have intervals for their standard atomic weights, namely hydrogen, lithium, boron, carbon, nitrogen, oxygen, magnesium, silicon, sulfur, chlorine, bromine and thallium. Isotopic abundances, isotope-delta values, and atomic weights for each of the lower and upper bounds of materials and compounds of these 12 elements are tabulated. Version 1.1 is

Dissolved organic carbon and nitrogen release from boreal Holocene permafrost and seasonally frozen soils of Alaska

Permafrost (perennially frozen) and active-layer (seasonally thawed) soils varying in soil carbon (C) and nitrogen (N) content and radiocarbon age were collected from three sites in interior Alaska to determine potential release of dissolved organic carbon (DOC), total dissolved N (TDN), dissolved organic nitrogen (DON), and dissolved inorganic nitrogen (DIN)
