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.

Vegetation, topography and sediment quality in the Lower Virgin River 2010-2012

Plant composition, geomorphic conditions and sediment properties before (2010) and after (2012) a 40 year return period flood (December 2010) at multiple transects within four reaches in the lower Virgin River, Nevada. The data contains four .csv files: localization (UTM coordinates of the transects), vegetation and geomorphology, species codes and sediment quality

Stable carbon and nitrogen isotope data for Siberian barn swallow subspecies collected during the breeding season

This dataset includes stable carbon and nitrogen isotope values for the inner tail retrices of three subspecies of barn swallow (Hirundo rustica rustica, H. r. tytleri, and H. r. gutturalis). Sampling was conducted in Russia (summer 2013), China (summer 2014), Mongolia (summer 2014), Japan (summer 2014), and western China (summer 2015) using mist nets. Stable carbon and nitrogen isotope data...

Absolute gravity data from Pinal County, Arizona, 2019

This dataset contains absolute-gravity measurements made using an A-10 absolute gravity meter (Micro-g Lacoste, Inc.) in 2019 in Pinal County, Arizona. Measurements were made at a total of 19 different stations used by the Arizona Department of Water Resources (ADWR) to monitor aquifer-storage changes. Data are presented in tabular and spatial vector (point) form, including relevant parameters...

Evapotranspiration within Blue Cypress Marsh, Vero Beach, Florida, 2015 to 2018

The dataset consists of a table in Excel format of daily evapotranspiration (ET) from 12/1/2015 to 6/13/2018 at ET station within the Blue Cypress Marsh Conservation Area near Vero Beach, Florida. Evapotranspiration was estimated using eddy-covariance methods. Data processing followed methods outlined by Shoemaker and others (2011). Ancillary data includes net radiation, latent heat,...

Data in support of Development of Regression Equations for the Estimation of Flood Flows at Ungaged Streams in Pennsylvania

Regression equations, which may be used to estimate flood flows at select annual exceedance probabilities, were developed for ungaged streams in Pennsylvania. The equations were developed using annual peak flow data through water year 2015 and basin characteristics for 285 streamflow gaging stations across Pennsylvania and surrounding states. The streamgages included active and discontinued...
