Data and Tools

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.

Image: Stranded Sea Otters Offer Valuable Data
November 21, 2017

Annual California sea otter stranding data

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.

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. 

Uranium mine evaporation pond
November 17, 2017

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). 

Graph of carp egg terminal fall velocity
November 15, 2017

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.

2017 Known and Probable Grizzly Bear Mortalities in the Greater Yellowstone Ecosystem

Identifying the locations and causes of grizzly bear mortality is another key component in understanding the dynamics of this population. Over 80% of all documented bear mortalities are human-caused. Tracking human-caused bear deaths helps define patterns and trends that can direct management programs designed to reduce bear mortality.

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.

National park sample locations used to calculate vulnerability to projected climate and land use changes from 2080-2099
November 15, 2017

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.
