From 2022 through 2024, the U.S. Geological Survey (USGS) conducted a study in cooperation with the Arkansas River Basin Regional Resources Planning Group (Southeastern Colorado Water Conservancy District, Colorado Springs Utilities, Pueblo Water, Lower Arkansas Valley Water Conservancy District, Aurora Water, and Upper Arkansas Water Conservancy District) to establish a basin-wide water...

This dataset contains the results from 80 visual encounter surveys at two wetlands in Palmetto Island State Park, Vermillion Parish, Louisiana from August 2015 to April 2019. These surveys mainly targeted snakes but small turtles and anoles were also opportunistically captured. Captured animals were swabbed to determine the prevalence of Ophidiomyces ophiodiicola, the causative agent of...

The 'ōpe‘ape‘a, also known as the Hawaiian hoary bat (Lasiurus semotus; Chiroptera: Vespertilionidae), is a solitary, insectivorous, and foliage-roosting endemic species. We investigated day-roost lability and fidelity, nocturnal activity patterns at the roost, and long-term use of roosts by 'ōpe‘ape‘a. The full data release consists of six tabular datasets: (1) Island of Hawai‘i, 'ōpe...

This data release documents movement of the toe of Cleveland Corral Landslide, El Dorado County, CA from October 1, 2016, to September 30, 2017, based on GPS data from near real-time monitoring. Raw GPS data from L1-only receivers were recorded in 15 second epochs using data acquisition systems and radio telemetry developed by the USGS Volcano Hazards Program. The overall system, named...

In 2002, tropical storm Chata’an triggered more than 250 landslides in Chuuk, Federated States of Micronesia (Harp and others, 2004). This data release includes shapefiles of the original mapping from oblique aerial photographs of landslide-affected areas (source and runout) (Harp and others, 2004), extraction of height (H) and length (L) from the original mapped landslides, and revised...

This dataset is the fourth installment of a yearly connectivity update for forested habitat within the Great Lakes Restoration Initiative's (GLRI) Terrestrial Habitats & Connectivity (TH&C) work group's Pilot Area. The Pilot Area is a region of the northern Great Lakes Basin between Ashland, WI and the Keweenaw Peninsula and is bounded by Lake Superior in the north and the basin boundary...

This dataset is the fourth installment of a yearly connectivity update for open habitat within the Great Lakes Restoration Initiative's (GLRI) Terrestrial Habitats & Connectivity (TH&C) work group's Pilot Area. The Pilot Area is a region of the northern Great Lakes Basin between Ashland, Wisconsin and the Keweenaw Peninsula and is bounded by Lake Superior in the north and the basin...

Bulk organic geochemical, major and trace element, and mineralogical measurements were made on samples of the Late Cretaceous Mancos Shale collected from the Blue Road outcrop off of South Millers Canyon Road/Blue Road approximately 3.5 miles south of U.S. Interstate 70 (Emery County, Utah). The data was collected as part of a regional evaluation of paleoenvironmental conditions during...

The Emporia 1:100,000-scale quadrangle straddles the Tidewater Fall Line in southern Virginia and includes a small part of northernmost North Carolina. Sediments of the coastal plain underlie the eastern three-fifths of this area. This data release contains geochronology from sediment samples collected in the eastern half of the Emporia 30’ x 60’ quadrangle, Virginia and North Carolina...

These data contain acceleration, pitch, yaw, roll, and ancillary data collected by acceleration data loggers (ADL) attached to four sea turtle species: green (Chelonia mydas) sea turtles, hawksbill (Eretmochelys imbricata) sea turtles, Kemp's ridley (Lepidochelys kempii) sea turtles, and loggerhead (Caretta caretta) sea turtles. A total of 54 nesting events and 76 non-nesting emergence...
