Data Releases
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.

Mean annual water-budget components for the Island of Kauai, Hawaii, for recent conditions, 1978-2007 rainfall and 2010 land cover (version 2.0)
The shapefile associated with this metadata file represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Kauai, Hawaii. The water-budget components in the shapefile were computed by a water-budget model for a scenario representative of recent conditions (1978-2007 rainfall and 2010 land cover), as described in USGS Scientific Investigations Report (

The shapefile associated with this metadata file represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Maui, Hawaii. The water-budget components in the shapefile were computed by a water-budget model for a scenario representative of current conditions (2001-10 rainfall and 2001-10 land cover), as described in USGS Scientific Investigations Report
Mean annual water-budget components for the Island of Maui, Hawaii, average climate conditions, 1978-2007 rainfall and 2010 land cover (version 2.0)
This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Maui, Hawaii. The water-budget components in the shapefile were computed by a water-budget model for a scenario representative of average climate conditions (1978-2007 rainfall) and 2010 land cover, as described in USGS SIR 2014-5168. The model was developed for estimating ground

Western US Ruggedness Reclassified into 6 Classes
"Vector Ruggedness Measure (VRM) measures terrain ruggedness as the variation in three-dimensional orientation of grid cells within a neighborhood. Vector analysis is used to calculate the dispersion of vectors normal (orthogonal) to grid cells within the specified neighborhood. This method effectively captures variability in slope and aspect into a single measure. Ruggedness values in the output
Linear Deconvolution Mineral Maps of Compositionally Variable Dune Fields in the Western United States and Alaska
These geotiffs represent the raster GIS outputs of Linear Deconvolution (Linear Spectral Unmixing) analysis of ASTER image pixels covering various sand dune and sand sheet fields throughout the Western United States and Alaska. The accompanying sets of zip file contains linear deconvolution derived mineral fractional abundance maps for various 2-, 3-, 4,- and 5-component mixture models of various

Western Pond Turtle (Actinemys marmorata) Monitoring and Assessment Data from the Trinity River, California (2013-2017)
A key objective of the Trinity River Restoration Program (TRRP) is maintaining and enhancing other wildlife populations through the restoration initiatives. For herpetological species, the foothill yellow-legged frog and western pond turtle have been identified as important species on which to focus monitoring efforts due to their status as California state-listed Species of Concern. As a result,
High-resolution bathymetry and acoustic-backscatter data collected in 2004, 2005, 2007, and 2010 in Skagit Bay, Washington
This data release provides the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center (PCMSC) 2004, 2005, 2007, and 2010 bathymetry data that was collected in Skagit Bay, Washington as well as a merged 2005-2010 bathymetry grid.

USGS Barnegat Bay Hydrodynamic Model for March-September 2012
Simulation of hydrodynamic circulation in Barnegat Bay for the period from 03-01-2012 to 10-01-2012. The bathymetry of the model was based on the National Ocean Service Hydrographic Survey data, and updated with recent bathymetric measurements. At the landward end (western boundary), we specified point sources of freshwater in accordance with USGS streamflow measurements at 7 gauges, and a radiati
