Continued Geophysical Logging in the vicinity of the GMH Electronics Superfund Site near Roxboro, North Carolina
The collection of borehole geophysical logs and images and continuous water-level data was conducted by the U.S. Geological Survey South Atlantic Water Science Center in the vicinity of the GMH Electronics Superfund site near Roxboro, North Carolina, during December 2012 through July 2015. The study purpose was part of a continued effort to assist the U.S. Environmental Protection Agency in the de
Drought Data: Vegetation
Realtime Vegetation Index Drought Data
A Multiscale Index of Landscape Intactness for the Western U.S.
Landscape intactness has been defined as a quantifiable estimate of naturalness measured on a gradient of anthropogenic influence. We developed a multiscale index of landscape intactness for the Bureau of Land Managements (BLM) landscape approach, which requires multiple scales of information to quantify the cumulative effects of land use. The multiscale index of landscape intactness represents a
Memphis Area Groundwater-Level Network
Groundwater Watch is a supplemental tool to NWISWeb and, as such, is able to provide additional benefits to the groundwater community. NWIS is the authoritative database for USGS groundwater data, and NWISWeb is the public interface for these groundwater data. This is information pertaining to the Memphis Area Groundwater-Level Network.
Evapotranspiration (ET) data at Dead River forested wetland site, Hillsborough County, Florida, December 2009 - February 2016
The data set consists of evapotranspiration measurements made at the USGS Dead River forested wetland climate station beginning November 21, 2009 and ending February 29, 2016. Annual ET rates corrected to a near-surface energy-budget varied from 1448 mm (2012) to 1614 mm (2010). The eddy-covariance method was used, with high-frequency sensors installed above the forest canopy to measure sensible a
Geospatial database of the study boundary, sampled sites, watersheds, and riparian zones developed for Midwest Stream Quality Assessment
The Midwest Stream Quality Assessment is the first of several regional studies that are being conducted as part of the Regional Stream Quality Assessment (RSQA) project, a component of the Cycle 3 National Water Quality Assessment (NAWQA) project. The MSQA was a collaborative study amongst NAWQA, the USGS Columbia Environmental Research Center (CERC), and the USEPA National Rivers and Streams Asse
Supporting Data: Complex Mixtures of Pesticides in Midwest U.S. Streams Indicated by POCIS Time-Integrating Samplers
The Midwest United States is an intensely agricultural region where pesticides in streams pose risks to aquatic biota, but temporal variability in pesticide concentrations makes characterization of their exposure to organisms challenging. To compensate for the effects of temporal variability, we deployed polar organic chemical integrative samplers (POCIS) in 100 small streams across the Midwest fo
Crest-Stage Gage Network (New York)
In cooperation with the New York State Department of Transportation, the New York Water Science Center maintains a network of crest-stage gages to improve flood frequency statistics generated at locations across the state.
Associated data for Water- and Sediment-Quality in the Albemarle Sound, North Carolina, 201214
This data release contains environmental and quality control results for chemical, biological, and physical sampling of water and bed sediment from Albemarle Sound and associated tributaries between 2012 and 2014 referenced in USGS OFR 2016-1171. Appendix 1 contains all quality control results to characterize the bias and variability of sampling, handling, and analysis of water, phytoplankton, and
Datasets for determining the origin of shallow lakes in the Khorezm Province, Uzbekistan, and the history of pesticide use around these lakes
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 content of 12 lakes in
