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.
Depth-to-water area polygons, isopleths showing mean annual runoff, 1912-1963, and water-level altitude contours for the Humboldt River Basin, Nevada
This data set consists of 1:500,000-scale isopleths showing mean annual runoff, 1912-1963, for the Humboldt River Basin, Nevada as published in the Nevada Department of Conservation and Natural Resources Water Resources Bulletin 32 titled "Hydrologic reconnaissance of the Humboldt River basin, Nevada", 1966.
The California Sea Otter Stranding Network is part of the USGS effort to monitor southern sea otters (Enhydra lutris nereis) and provide data to the U.S. Fish and Wildlife Service. Since 1985, stranded otters from throughout their California coastal range have been collected and analyzed to inform resource management on recovery and conservation of the species.
Soil chemistry adjacent to roads treated with dust control products at Squaw Creek National Wildlife Refuge
In order to quantify the effect of dust suppressant treatment on roadside soils, we took replicated composite soil samples one year after treatment at 1m and 4m from the road’s edge, and analyzed samples for a suite of soil chemistry variables (pH, conductivity, NO3-N, P, K, Ca, Mg, Na and S). We also assessed dust suppressant product residues in the soil.
Amphibian acoustic data from the Arizona 1, Pinenut, and Canyon breccia pipe uranium mines in Arizona
The data consists of a summary of amphibian acoustic recordings at Canyon, Arizona 1, and Pinenut mines near the Grand Canyon. Original raw acoustic recordings used to create this summary data table are archived at Columbia Environmental Research Center.
Sediment chemistry and sediment toxicity in wadable streams across the Midwestern United States, 2013.
Data presenting chemistry (PAHs, organochlorines, PCBs, trace elements, and current use pesticides) and toxicity results from freshwater stream sediments collected from 99 wadable stream sites across eleven states in the Midwestern United States.
Chemistry, radiation and histopathology data in support of manuscript "Pre-mining trace element and radiation exposure to biota from a breccia pipe uranium mine in the Grand Canyon (Arizona, USA) watershed"
Data collected to characterize the pre-mining concentrations of total arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), mercury (Hg), nickel (Ni), selenium (Se), thallium (Tl), U, and zinc (Zn); radiation levels; and histopathologies in biota (vegetation, invertebrates, amphibians, birds, and mammals) at the Canyon Mine.
A comparison of four pore water sampling methods for mixed metals and dissolved organic carbon, and implications for sediment toxicity evaluations-Data
Data representing comparison of four commonly-applied techniques for obtaining pore water samples for the quantification of nickel, copper, zinc, arsenic, cadmium, lead and dissolved organic carbon (DOC), including peepers, push points, centrifugation, and diffusive gradients in thin films (DGTs).
Assessing Techniques to Enhance Barrier Characteristics of High-head Navigation Dams on the Upper Illinois River: Data
The dataset is comprised of river conditions at La Grange, Peoria, Starved Rock, Marseilles, and Dresden Island Locks and Dams, along the Illinois River. Data were recorded bihourly from 1985 – 2016. For each location, pool elevation (ft), tailwater elevation (ft), head height (ft), discharge (cfs), and total gate openess.
Data collected in June 2016 as part of a dye-trace experiment in the Missouri River downstream from Fort Peck Dam, Montana, USA. Fluorometers were deployed at 8 measurement stations over a 135-km study reach.
Data for "Comparison of size, terminal fall velocity and density of bighead, silver, and grass carp eggs for use in drift modeling"
Physical characteristics of the eggs as a function of post fertilization time. We recorded mean egg diameter and terminal fall velocity for eggs from each species during the first five hours of development, and at approximately 12 and 22 hours post fertilization.
Quantifying habitat benefits of channel reconfigurations on a highly regulated river system, Lower Missouri River, USA-Data
Depth and velocity grids centerpoints generated from hydrodynamic model (SRH-2D) simulations run for a range of discharges in the Fairview reach of the Yellowstone River, MT, the Miami and Lisbon-Jameson reaches of the Lower Missouri River.
5 datasets to underlie the bend-scale classification of Lower Missouri River. Classification was based on geomorphic and engineering variables for 257 bends from Sioux City, Iowa to the confluence with the Mississippi River near St. Louis, Missouri.
