Four-place table of standard atomic weight values of hydrogen through uranium compared since 1961

Four-figure standard atomic weights of the chemical elements are shown for 1961, 1975, 1983, 2007, 2009, 2011, 2013, 2015, and the current value for 2016. Values between 1975 and 2015 are only shown when there is a change in value with respect to the previous column.

National 1-kilometer rasters of selected Census of Agriculture statistics allocated to land use for the time period 1950 to 2012

This dataset consists of a series of rasters covering the conterminous United States. Each raster is a one kilometer (km) grid for 18 selected Census of Agriculture statistics mapped to land use pixels for the time period 1950 to 2012. A supplemental set of 9 statistics mapped at the entire county level are also provided as 1-km rasters. The rasters are posted as ArcGIS grids. The statistics...

MODFLOW-NWT model used to assess groundwater availability in the Northern Atlantic Coastal Plain aquifer system from Long Island, New York to North Carolina

A three-dimensional, groundwater flow model was developed with the numerical code MODFLOW-NWT to
represent changes in groundwater pumping and aquifer recharge in the Northern Atlantic Coastal Plain
aquifer system from Long Island, New York to North Carolina. The model was constructed using existing
hydrogeologic and geospatial information to represent the aquifer system...

Rosen et al JoPL Pesticide Dataset

This data release contains the data used to interpret the origin of the shallow lakes in the Khorezm Province, Uzbekistan, and the history of pesticide use around these lakes. The data include 1) lake sediment core data for age dating (cesium-137 and lead-210) for 12 lakes in Uzbekistan, 2) lake sediment core data for loss on ignition (LOI550)for determining organic carbon cont

Bifenthrin Concentration, Percent Organic Matter, and Toxic Units, for Stream Sites Collected as Part of the Midwest Stream Quality Assessment

Direct and indirect ecological effects of the widely used insecticide bifenthrin on stream ecosystems are largely unknown. To investigate such effects, a manipulative experiment was conducted in stream mesocosms that were colonized by aquatic insect communities and exposed to bifenthrin-contaminated sediment; implications for natural streams were interpreted through comparison of mesocosm res...

MODFLOW-NWT model used to evaluate the potential effect of groundwater pumpage and increased sea level on canal leakage and regional groundwater flow in Miami-Dade County, Florida

A three-dimensional, surface-water/groundwater model (MODFLOW-NWT with the Surface-Water
Routing Process) was developed to the predict the effects of groundwater pumpage on canal
leakage and regional groundwater flow in urban portions of Miami-Dade County, Florida. The
model was calibrated by using observation data collected from 1997 through 2004. The model
calibration...

Study Boundary for the U.S. Geological Survey Southeast Stream Quality Assessment

In 2015, the second of several Regional Stream Quality Assessments (RSQA) was done in the southeastern United States. The Southeast Stream Quality Assessment (SESQA) was a study by the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA) project. One of the objectives of the RSQA, and thus the SESQA, is to characterize the relationships between water-quali

MODFLOW-NWT model used to evaluate groundwater/surface-water interactions in the Bad River Watershed, Wisconsin

A groundwater-flow model was developed for the Bad River Watershed and surrounding area by using
the U.S. Geological Survey (USGS) finite-difference code MODFLOW–NWT. The model simulates
steady-state groundwater-flow and base flow in streams by using the streamflow routing (SFR)
package. The model was calibrated to groundwater levels and base flows obtained from the USG
