Data and Tools
Biology and Ecosystems Datasets
Mapping, Remote Sensing, and Geospatial Data
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.
Acoustic doppler current profiler raw measurements on the Missouri and Yellowstone rivers, 2000-2016, Columbia Environmental Research Center
Acoustic doppler current profiler (ADCP) measurements on the Missouri and Yellowstone Rivers between the years 2000 and 2016.
Table containing raw and normalized scores used to calculate vulnerability of 60 American Midwestern national parks to projected climate and land use changes for 2080-2099
Raw and relative (normalized) data for metrics measuring exposure (yellow columns), sensitivity (green columns), constraints on adaptive capacity (blue columns), and vulnerability for units in the US National Park Service Midwest administrative region. Stippled columns contain relative (normalized) data used to calculate the corresponding component.
Invasive plant inventory sample locations and cover values for Missouri River bottoms.
Floral survey of 11 cliffs in the Manassas National Battlefield Park. We recorded 282 species in 194 genera and 83 families, including 23 newly documented species for the park. Locations of bluffs sampled. GIS data complement the USGS Data Series "A Floral Survey of Cliff Habitats along Bull Run at Manassas National Battlefield Park, Virginia" and accompanying Microsoft Access database.
Survey of contamination in soils and sediment of Palmyra atoll, using a hand-held X-Ray Fluorometer (XRF) to measure the concentration of 25 elements.
Concentration trends for lead and calcium-normalized lead in fish fillets from the Big River, a mining-contaminated stream in southeastern Missouri USA
Lead (Pb) and calcium (Ca) concentrations were measured in fillet samples of longear sunfish (Lepomis megalotis) and suckers (Catostomidae) collected in December 2005 from the Big River, which drains a historical mining area in southeastern Missouri, where a consumption advisory is in effect due to elevated Pb concentrations in fish.
Development of high surface area organosilicate nanoparticulate thin films for use in sampling hydrophobic compounds in sediment-Data
The data set describes the characterization of organosilica thin films for adsorbing the bioavailable fraction of PCBs from sediment collected near Anniston Alabama. We developed novel nanoporous organosilicate (NPO) film as an extraction phase for hydrophobic contaminants and demonstrated its application in water and sediment.
Acute sensitivity of a broad range of freshwater mussels to chemicals with different modes of toxic action-data
The data release includes the data collected from multiple acute 96-hour toxicity tests with up to 20 chemicals and five mussel species in water exposures.
These data support studies from 1997-2006 on potential toxicity of mercury concentrations within the lower Carson River system to piscivorous birds - snowy egrets, black-crowned night-herons, and double-crested cormorants.
Two commonly used human breast luciferase transactivation cell bioassays, the VM7Luc4E2 cell bioassay and the MDA-kb2 cell bioassay were adapted to 384-well formats for HTS of endocrine-active substances. This data demonstrate that by accounting for protein amount in the cell lysates, antagonistic agents can easily be distinguished from cytotoxic agents in the MDA-kb2 and VM7Luc4E2 cell...
USGS Southwest Repeat Photography Collection: Kanab Creek, southern Utah and northern Arizona, 1872-2010
This data release contains data, repeat images, and field notes collected from 80 repeat photography stakes along Kanab Creek 1872 and 2010. The Kanab Creek repeat photography collection is part of the USGS Southwest Repeat Photography Collection assembled over decades by USGS scientists Drs. Robert H. Webb and Raymond M. Turner and curated by the Southwest Biological Science Center.
The data set is a table of counts, with the rows being the transcripts detected in the samples in the experiment and the columns identifying the samples. Four mussles were exposed to normal freshwater and four mussels were exposed to high salinity (two ppt), for a period of seven days.
