Data Releases
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.

Groundwater Quality Data from the Mohawk and Western New York River Basins, New York, 2016 Groundwater Quality Data from the Mohawk and Western New York River Basins, New York, 2016
From July through December 2016, 56 environmental samples were collected from the Mohawk and Western New York River Basins. Samples were collected from nine production wells and 13 domestic wells in the Mohawk River Basin, and 17 production wells and 17 domestic wells in the Western New York River Basins. Samples were collected and processed using standard USGS methods and analyzed for...
Estimated crop irrigation water use withdrawals in Harquahala Irrigation Non-Expansion Area Groundwater Basin, Arizona for 2021 Estimated crop irrigation water use withdrawals in Harquahala Irrigation Non-Expansion Area Groundwater Basin, Arizona for 2021
Observations of irrigated agricultural land within the Harquahala Irrigation Non-Expansion Area Groundwater Basin in Arizona. Crops were verified in situ three times in 2021, first on March 3rd, then on May 19th, and finally on September 2nd; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program...
Regional patterns in foraging ecology between adult roseate and common terns in the Northwest Atlantic Regional patterns in foraging ecology between adult roseate and common terns in the Northwest Atlantic
Co-occurring species with similar resource requirements often partition ecological niches. In the Northwest Atlantic (NWA), endangered roseate terns (Sterna dougallii) nest almost exclusively in coastal island colonies alongside common terns (S. hirundo). Roseate terns are prey specialists compared to common terns, which are opportunistic generalists; however, the two species forage on...
O'ahu waterbird movement from 2016 to 2018 O'ahu waterbird movement from 2016 to 2018
This data release includes data and metadata containing estimated and predicted locations of radio telemetered Hawaiian waterbirds. Radio telemetry data was collected using an automated radio telemetry network from March 2016 to August 2018 on O'ahu, Hawaii, for three species: ʻAlae ʻula (Hawaiian Gallinule; Gallinula galeata sandvicensis), ʻAlae keʻokeʻo (Hawaiian Coot; Fulica alai)...
Metabarcode sequencing of aquatic environmental DNA from the Potomac River Watershed, 2015-2020 Metabarcode sequencing of aquatic environmental DNA from the Potomac River Watershed, 2015-2020
Biological indicator taxa have long been used for integrative assessments of water quality, particularly benthic invertebrate groups such as arthropods. While standardized protocols have been developed to calculate 'biological index' scores based on the abundances of these taxa, such systems are challenging to implement at large scales due to the sampling effort required, taxonomic...
Major and trace element geochemistry and mineralogy of ferromanganese crusts from seamounts within the Tuvalu Exclusive Economic Zone Major and trace element geochemistry and mineralogy of ferromanganese crusts from seamounts within the Tuvalu Exclusive Economic Zone
Ferromanganese crusts were collected via dredge from seamounts within the Tuvalu Exclusive Economic Zone in the Pacific Ocean during cruise RR1310 funded by the National Science Foundation aboard the R/V Roger Revelle in 2013. USGS scientists requested these ferromanganese crust samples from the Oregon State University Marine and Geology Repository where they had been archived...
