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.
These data were used for the development and validation of the automated workflow for mechanistic segregation of geomorphic transport mechanisms presented in the manuscript "Geomorphic Process from Topographic Form: Automating the Interpretation of Repeat Survey Data in River Valleys."
Data were compiled or measured (depending on the trait) for 110 plant species which were documented in vegetation monitoring surveys in years 2012-2014 along the Colorado River through Grand Canyon National Park. New trait data were collected for specific leaf area, stem specific gravity, δ13C, δ15N, percent carbon and nitrogen, and carbon:nitrogen ratio.
Physical, chemical and bioassay data from an evaluation of metal-contaminated sediments and pore water from the Upper Columbia River, Washington, 2013-2014
Chemistry and toxicity data from sediment toxicity tests conducted by the USGS Columbia Environmental Research Center (CERC) with 66 sediment samples collected from in and around the Upper Columbia River in the fall of 2013. Toxicity testing was conducted with the amphipod, Hyalella azteca, the midge Chironomus dilutus, and the mussel Lampsilis siliquoidea.
Water resources data are published annually for use by engineers, scientists, managers, educators, and the general public. These archival products supplement direct access to current and historical water data provided by the National Water Information System (NWIS). Beginning with Water Year 2006, annual water data reports are available as individual electronic files.
WERC scientists conduct annual population surveys of the southern sea otter, a federally listed threatened species. Download annual survey data from 1985 to present.
Hawaiʻi Volcanoes National Park was surveyed for landbirds and landbird habitat from February through April 2015 and February through April 2016. This information provides the second datum in the time-series of Pacific Island Network (PACN) monitoring for long-term trends in landbird distribution, density, and abundance (initial surveys conducted in 2010). Report available.
Area of the Named Glaciers of Glacier National Park (GNP) and Flathead National Forest (FNF) Derived from Aerial and Satellite Imagery, 1966, 1998, 2005, 2015
These data represent a time series of the 37 named glaciers of Glacier National Park, MT, USA and two named glaciers in the Flathead National Forest.
The 1966-2016 North American Breeding Bird Survey dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily June, along thousands of randomly established roadside survey routes in the United States and Canada.
Data tables in support of manuscript "δ13C and δ15N in the Endangered Kemp's Ridley Sea Turtle Lepidochelys kempii After the Deepwater Horizon Oil Spill"
Carbon and nitrogen isosope ratios of satellite-tagged turtles to 1) assess changes in foraging strategies of nesting Lk sampled in 2010 (the year of the Deepwater Horizon oil spill) and two subsequent post-spill years; and 2) estimate the proportion of females that were within the area affected by the oil spill, the latter via discriminant analysis.
This USGS data release includes complete CSDGM metadata, a digitized set of original bathythermogram print photos, and the temperature and depth data collected from each bathythermograms using open-source software. In addition, because of their historical value and potential future use, this data release includes the cruise logs, which include complementary nautical and research notes.
This dataset consists of modeled projections of land use and land cover and population for the State of California for the period 1970-2101. For the 1970-2001 period, we used the USGS's LUCAS model to "backcast" LULC, beginning with the 2001 initial conditions and ending with 1970. For future projections, the model was initialized in 2001 and run forward on an annual time step to 2100.
Summary of total mercury concentrations in dragonfly larvae, western mosquitofish, and tree swallow eggs collected from Cosumnes River Preserve 2011 – 2013
In order to document potential environmental health risk in Cosumnes River Preserve wetlands due to mercury, we analyzed dragonfly larvae, western mosquitofish, and tree swallow eggs collected from wetlands and rice fields of the Preserve from 2011 to 2013.
