Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Airborne Geophysical Surveys over the Eastern Adirondacks, New York State

Airborne geophysical surveys were conducted in the eastern Adirondacks from Dec. 7, 2015 - Dec. 21, 2015, by Goldak Airborne Surveys. The area was flown along a draped surface with a nominal survey height above ground of 200 meters. The flight line spacing was 250 meters for traverse lines and 2500 meters for control lines. Here we present downloadable magnetic and radiometric (gamma spec

MODFLOW-USG model of groundwater flow in the Wood River Valley aquifer system in Blaine County, Idaho

A three-dimensional numerical groundwater flow model (MODFLOW-USG) was developed for the
Wood River Valley (WRV) aquifer system, south-central Idaho, to evaluate groundwater and
surface-water availability at the regional scale. The U.S. Geological Survey (USGS), in
cooperation Idaho Department of Water Resources, used the transient groundwater flow
model to simulate...

Map 14: ArcGIS layer showing contours of the difference in the 25th percentile of all water levels from the water-year periods 1990 to 1999 and 2000 to 2009 (feet)

Statistical analyses and maps representing mean, high, and low water-level conditions in the surface water and groundwater of Miami-Dade County were made by the U.S. Geological Survey, in cooperation with the Miami-Dade County Department of Regulatory and Economic Resources, to help inform decisions necessary for urban planning and development. Sixteen maps were created that show contours

Fluctuating Asymmetry in Waterbirds in Relation to Mercury Exposure

The dataset includes the bird species, sex, mercury concentration in breast feathers and whole blood, and the composite measure of fluctuating asymmetry. Statistical models were developed for each species to analyze the relationship between mercury exposure in either breast feathers or whole blood and the composite measure of fluctuating asymmetry, while accounting for the sex of each bird....

Simulated data supporting inbreeding rate estimates from incomplete pedigrees

This data release includes: (1) The data from simulations used to illustrate the behavior of inbreeding rate estimators. Estimating inbreeding rates is particularly difficult for natural populations because parentage information for many individuals may be incomplete. Our analyses illustrate the behavior of a newly-described inbreeding rate estimator that outperforms previously described ap...

Spatial distribution of Rhodamine WT dye concentration measured in the Chicago Sanitary and Ship Canal, Chicago, IL (November 15-18, 2011)

A boat equipped with a differential Global Positioning System (GPS) receiver (Hemisphere Crescent A100 Smart Antenna) and a Turner Designs C3 submersible fluorometer was used to survey the spatial distribution of the Rhodamine WT dye in the Chicago Sanitary and Ship Canal (CSSC) throughout the study area. The fluorometer was installed in a fixed, downlooking orientation approximatel

Table 1 - Inventoried irrigated acreage summarized by crop and county in the Suwannee River Water Management District, 2015

To accurately estimate agricultural water use or to project future water demands, a detailed inventory of current irrigated crop acreage is needed at a high level of resolution. In many Florida counties this kind of detailed high-resolution inventory is not available. A detailed digital map and summary of irrigated acreage during the 2015 growing season was developed for 13 of the 15 counties...
