Data Releases

This digital dataset of a three-dimensional hydrogeologic framework for the Rio Grande Transboundary region of New Mexico, Texas, USA and Northern Chihuahua, Mexico defines the geometry, extent, and character of aquifers of the region and is intended as the digital hydrogeologic input data for numerical simulation of the groundwater system. The data consist of a single GeoDatabase (RGTIHM_3DHFM

Water-level gauges were deployed at two sites in West Falmouth Harbor between May and October 2016. Two sequential deployments were required to provide measurements for the entire period. One gauge was mounted under the town-owned West Falmouth boat dock and the other on the private Associates dock near the mouth of the Harbor. Each gauge supported two pressure sensors mounted in a stilling we

A detailed inventory of the current irrigated crop acreage is now available to accurately estimate agricultural water use and future water demands in Polk County, Florida. A detailed digital map and summary of irrigated acreage was developed in an effort to improve the accuracy of crop acreage, type, and location for the 2016 growing season. The irrigated areas were delineated using land-use data

The West Hills of Portland, in the southern Tualatin Mountains, trend northwest along the west side of Portland, Oregon. These silt-mantled mountains receive significant wet-season precipitation and are prone to sliding during wet conditions, occasionally resulting in significant property damage or casualties. In an effort to develop a baseline for interpretive analysis of the groundwater response

This data contains information on the hematological and biochemical response variables of captive Pacific Common Eiders (Somateria mollissima v-nigrum) implanted with abdominal satellite transmitters with percutaneous antennas.

This data release contains two tables of information on behavior and productivity of greater white-fronted geese nesting near Point Lonely, Alaska, 2013-2014: transcriptions of nest photographs obtained by time-lapse photography at 1-minute intervals, and characteristics of nests monitored with cameras and via periodic nest visits. Data were collected as part of the USGS Changing Arctic Ecosystem

This dataset provides a near-real-time estimate of 2017 herbaceous annual cover with an emphasis on annual grass (Boyte and Wylie. 2016. Near-real-time cheatrass percent cover in the Northern Great Basin, USA, 2015. Rangelands 38:278-284.) This estimate was based on remotely sensed enhanced Moderate Resolution Imaging Spectroradiometer (eMODIS) Normalized Difference Vegetation Index (NDVI) data ga

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen B

Scientific tools such as physiological analysis are fundamental to understand invasive species tolerances and responses to different environmental conditions. The Amazon fish Astronotus ocellatus, popularly known as oscar, was introduced worldwide and became invasive in many places. Specimens of A. ocellatus were abruptly submitted to salt stress of 14 and 20 ppt, for 3 and 8 hours to analyze its

Provided here are the SWAN wave model input of grid 4 with pit 3 configuration and output of significant wave height, dominant wave period, and mean wave direction resulting from simulation of wave scenarios at the Breton Island, LA, as described in USGS Open-File Report 2015-1055 (https://doi.org/10.3133/ofr20151055). There are 128 individual scenarios that are based on significant wave height (H

This USGS data release contains (1) geologic-unit top-surface altitudes in boreholes and (2) aquifer-test time-series water-level drawdowns, recoveries, and supporting data from the Piney Point aquifer in Virginia from 2009 through 2015. Extents, compositions, configurations, and geologic relations of six geologic units that compose the Piney Point aquifer were determined from geologists logs of s

The data release for Gospel-Hump Wilderness Area and the Magruder Corridor and Special Mining Management Zone Additions to the Frank Church River of No Return Wilderness Area, and adjacent areas Idaho and Montana, contains a subset of previously unpublished geochemical data from the 1979-1984 projects. In the case of Gospel-Hump Wilderness Area study (Lund and Esparza, 1990), the purpose of the pr
