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.

DATA RELEASE - Stream Drift Sampling in Arizona, 2014

Data were compiled from field drift collections and from a meta-analysis of published drift literature. Field data were collected in 2014 from the Colorado River downstream of Glen Canyon Dam, Arizona. Data represent flow meter measurements taken at the mouth and adjacent to a drift net, and suspended solids concentrations collected by the drift net, over varying net deployment durations.

Oregon Spotted Frog (Rana pretiosa) Monitoring in the Oregon Cascades 2012-2016

This dataset contains information from visual encounter surveys conducted between 2012 and 2016 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in the Oregon Cascade Mountain Range. We surveyed 91 sites using a rotating frame design in the Klamath and Deschutes Basins, Oregon, which encompass most of the species' core extant range.

DATA RELEASE - Experimental Design Plant and Soil Measurement Data, Colorado Plateau, 2011

These plant and soil data were collected by Timothy M. Wertin and Sasha C. Reed in the spring, summer, and fall of 2011 at a climate manipulation experiment site near Moab, UT (38.521411, -109.470567). These data were collected to assess how warming affects leaf photosynthesis, soil CO2 efflux, and soil chemistry in plots of ambient and warming treatments.

USGS Geo Data Portal

The USGS Geo Data Portal (GDP) project provides scientists and environmental resource managers access to downscaled climate projections and other data resources that are otherwise difficult to access and manipulate. This user interface demonstrates an example implementation of the GDP project web-service software and standards-based data integration strategy.
