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.

Water Data Reports for Georgia, North Carolina, and South Carolina

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.

Hawai‘i Volcanoes National Park Landbird Surveys 2015-2016

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.

North American Breeding Bird Survey Dataset 1966 - 2016, version 2016.0

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.

California Land-change Projections

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.

DATA RELEASE - Channel Mapping of the Colorado River in Grand Canyon National Park, Arizona - May 2009, river miles 29 to 62

Bathymetric, topographic, and grain-size data were collected in May 2009 along a 33-mi reach of the Colorado River in Grand Canyon National Park, Arizona. Channel bathymetry was mapped using multibeam and singlebeam echosounders, subaerial topography was mapped using ground-based total-stations, and bed-sediment grain-size data were collected using an underwater digital microscope system.
