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.

Hawai‘i Island ʻōpeʻapeʻa (Hawaiian hoary bat; Lasiurus semotus) mist netting effort, capture, and tag retention, 2018–2021 Hawai‘i Island ʻōpeʻapeʻa (Hawaiian hoary bat; Lasiurus semotus) mist netting effort, capture, and tag retention, 2018–2021
‘Ōpe‘ape‘a (Hawaiian hoary bats; Lasiurus semotus) were surveyed at 23 sites on Hawaiʻi Island from 33 to 2,341 m elevation from May 2018 to August 2021. Of the 23 sites, 8 were established as fixed survey sites for sampling at repeated intervals from January 2019 through January 2021. We surveyed each fixed site at least once per four-month period (January–April, May–August, September...
Hawaiʻi Island ʻōpeʻapeʻa (Hawaiian hoary bat) roost data, 2018–2021 Hawaiʻi Island ʻōpeʻapeʻa (Hawaiian hoary bat) roost data, 2018–2021
Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island from 2018-2021. We examined resource selection at multiple spatial scales - perch location within a roost tree, roost tree, and forest stand. We used a discrete choice modeling approach to investigate roost selection and describe attributes of day-roost trees...
USGS Database of Mounds in Southwest Utopia Planitia Mars USGS Database of Mounds in Southwest Utopia Planitia Mars
Dataset contains latitude, longitude and additional attribute information for mounds in the lowlands of Mars. This version of the database contains data for mounds in the southwestern Utopia Planitia region of the martian lowlands.
Datasets for the 2015 potentiometric surface and water-level changes (2011-2013, 2013-2015) in the Sparta-Memphis aquifer, in Arkansas Datasets for the 2015 potentiometric surface and water-level changes (2011-2013, 2013-2015) in the Sparta-Memphis aquifer, in Arkansas
These datasets provide the locations of and groundwater-level altitudes from 273 wells that were used to construct a 2015 potentiometric contour surface of the Sparta-Memphis aquifer. Measurements were made from January through June 2015 and represent synoptic conditions. All wells were cased completely in and screened in the Sparta-Memphis aquifer. Groundwater-level data are also...
Topographic and multispectral reflectance products, aerial imagery, spectral reflectance profiles, vegetation surveys, and associated GPS data collected during uncrewed aircraft system (UAS) operations: Assateague Island National Seashore, Maryland, Octob Topographic and multispectral reflectance products, aerial imagery, spectral reflectance profiles, vegetation surveys, and associated GPS data collected during uncrewed aircraft system (UAS) operations: Assateague Island National Seashore, Maryland, Octob
Low-altitude (70 m above ground level) aerial images were collected over 5 areas of interest within the northern portion of Assateague Island National Seashore (ASIS) in mid-October, 2022. These images were collected to generate photogrammetric products (e.g. digital surface model (DSM), reflectance orthomosaic) for five areas of interest along the northern portion of the island to...
Groundwater Withdrawals in Florida and parts of Georgia, Alabama, and South Carolina, 19952010 Groundwater Withdrawals in Florida and parts of Georgia, Alabama, and South Carolina, 19952010
Groundwater withdrawals are published by county and use type every 5 years by the U.S. Geological Survey (http://water.usgs.gov/watuse/) and published values often do not specify the aquifer(s) from which the withdrawals are derived. The items included in this dataset represent estimates of water use by aquifer in the southeastern United States in order to provide better insight into the...
