Data

This dataset consists of data products derived from uncrewed aerial systems visible images and videos taken over three years from 2021 to 2024 over eskers at the Breiðamerkurjökull glacier margin in Iceland. This includes orthomosaics, digital elevation models (DEMs), elevation difference maps, shapefiles detailing the esker footprints that are visible in the previous datasets, videos of...

This metadata record contains two tables with reported and calculated amounts of biosolids applied to agricultural land within Virginia in 2024 at different scales. Included in the dataset are (1) mass of land-applied biosolids calculated for NHDPlus Version 2.1 (NHDPlusV2) reach catchments in 2024 as a CSV and (2) reported amount of biosolids applied to land by county in 2024 as a CSV...

We sequenced the prion protein gene from white-tailed deer from Southwest Wisconsin. The samples were provided by the Wisconsin Department of Natural Resources. The dataset includes sequencing chromatogram files and a summary table with the interpretation of the sequencing data.

Emergent marine terraces record past periods of relatively high sea level and are common on uplifting coasts worldwide. Such landforms are extensive around the Gulf of Corinth area of Greece and along the coast of California, USA. In the Gulf of Corinth region, marine terraces record Quaternary uplift due to ongoing basin extension on the northern side of the Africa-Eurasia-Aegean Sea...

As part of a larger study examining stream conditions and the effect of Best Management Practices in the Chesapeake Bay watershed, thirty small streams in the developed piedmont of Maryland, Washington, DC, and Virginia were instrumented and monitored for gage height (water level), water temperature, and air temperature using Onset HOBO sensors from March to September 2024. In addition...

We designed and implemented snake-resistant nestboxes and tested their efficacy as a conservation tool by comparing nest survival in nestboxes to natural nests for Aplonis opaca (Såli, Micronesian Starling) on Guam. During 2016-2018, we monitored 340 nest attempts by 40 A. opaca pairs nesting in nestboxes and 53 attempts by 32 pairs nesting in natural nests (outside of nestboxes), for a...

This data release contains principal facts of gravity measurements by previous studies and collected by the U.S. Geological Survey in 1994-2023 and a compilation of existing and new density and magnetic susceptibility data in northeastern California. Gravity data are processed to isostatic anomalies using reduction densities of 2670 and 2200 kilogram/cubic meter. This region is at the...

This dataset consists of 424 paleomagnetic sites from Newberry Volcano. 15 sites were analyzed at the natural remanent magnetization level, 256 sites were analyzed with blanket demagnetization, and 153 sites were analyzed with modern stepwise demagnetization protocols. 412 sites yield acceptable paleomagnetic data.

Heavy fog was hypothesized to interfere with flight of waterfowl by obscuring visibility and cause waterfowl to fly more in search for habitat below, which in turn, is likely to increase bioenergetic (caloric) cost related to increased time flying. The data sets include variables used to analyze the relationship between fog characteristics (occurrence, density, and longevity) and flight...

The following report summarizes the dating results from sedimentary deposits sampled by the USGS Geologic Harzards Team and analyzed at the USGS Luminescence Geochronology Laboratory. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose...

The 1966-2024 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes are roughly...

Snake fungal disease, which is caused by the fungal pathogen Ophidiomyces ophidiicola, is associated with severe skin infections and mortality in individual snakes. However, little has been described regarding how disease severity and impacts vary by snake populations and species. We describe mortality in rainbow snakes in Virginia, USA, linked to snake fungal disease. This data set...
