Data Releases

This data release provides the U.S. Geological Survey (USGS) Spectral Library Version 7 and all related documents. The library contains spectra measured with laboratory, field, and airborne spectrometers. The instruments used cover wavelengths from the ultraviolet to the far infrared (0.2 to 200 microns). Laboratory samples of specific minerals, plants, chemical compounds, and man-made materials w

This U.S. Geological Survey (USGS) Data Release provides derivative statistics of water used by Kansas public-supply systems in 2015. Gallons per capita per day is calculated using self-reported information in the Part B: Monthly Water Use Summary and Part C: Population, Service Connections, and Water Rates sections of the Kansas Department of Agriculture, Division of Water Resources' (DWR) annual

There are two datasets in the compressed file along with individual metadata files which completely describe the datasets. The first data set consists of county estimates of nitrogen and phosphorus in kilograms from animal manure for the conterminous United States for 2007 and 2012. These data are available as both text files and spreadsheets. These estimates were based on county-level population

On 21 May 2016, two Differential Optical Absorption Spectroscopy (DOAS) instruments were used to measure the radiance of scattered solar radiation passing through the plume emitted from Sabancaya Volcano, Peru. Spectra were recorded in the ultraviolet (UV: 280 425 nm) and visible (Vis: 450 780 nm) wavelength ranges at 0.6 and 1.2 nm resolution, respectively. Two distinct experiments were perform

These data were compiled from field drift collections and from a meta-analysis of published drift literature. Field data were collected in 2014 from the Colorado River downstream of Glen Canyon Dam, Arizona, from the Salt River downstream of Stewart Mountain Dam, Arizona, and from Wet Beaver Creek near the Village of Oak Creek, Arizona. These data represent flow meter measurements taken at the mou

In the face of sea level rise and as climate change conditions increase the frequency and intensity of tropical storms along the north-Atlantic Coast, coastal areas will become increasingly vulnerable to storm damage, and the decline of already-threatened species could be exacerbated. Predictions about response of coastal birds to effects of hurricanes will be essential for anticipating and counte

Tsunami travel time maps for Del Norte and Humboldt Counties in California in vector (shapefile) format for both slow and fast walking speeds and for bridges intact and bridges removed.

Surveys of the bathymetry and backscatter intensity of the sea floor of the Historic Area Remediation Site (HARS), offshore of New York and New Jersey, were carried out in 1996, 1998, and 2000 using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard ship Frederick G. Creed. The objective of the multiple echosounder surveys was to map the bathymetry and surficial sediments ov

Fish collections made at Buck Island Reef National Monument with the ichthyocide rotenone in 2001 at 58 stations followed by 10 days each in April 2011 and January 2012 surveying poorly sampled shoreline habitats with rotenone and clove oil and inland streams with seine.

These datasets, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in collaboration with the National Park Service, provide lidar-derived first-surface and bare-earth topography for Assateague Island National Seashore, Maryland and Virginia. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) during September 2005.

Lake Erie Biological Station (LEBS), located in Sandusky, Ohio, is a field station of the USGS Great Lakes Science Center (GLSC). LEBS is the primary federal agency for applied fisheries science excellence in Lake Erie. Since 2004, LEBS has participated in a collaborative, multiagency effort to assess forage fish populations in the western basin of Lake Erie. Assessing the distribution and abundan

It contains supporting data from the wetland morphology modeling to support the analysis on the landscape effects of Mississippi River diversions in the context of sea-level rise on soil organic carbon (SOC) sequestration along coastal Louisiana wetlands.
