This dataset is one table with results of tests to determine exposure of Chukchi Sea polar bears to a suite of pathogens. Results are serological tests for antibodies and tests of fecal samples for presence of parasites. Serologic assays were conducted for Toxoplasma gondii, Neospora caninum, Francisella tularensis, Coxiella burnetii, Leptospira spp., Brucella canis, Brucella abortus/suis, and can

Data include fasta files of full mitochondrial sequence data for the male and female mitotypes of the mucket (Ortamannia ligamentina). These have been deposited in the NCBI database under BioSample Accession number SAMN39271813, SRA Accession number SRR27608898, and GenBank Accession numbers : PP103562 and PP103563.

Wood Valley Pit Crater is a nearly circular pit approximately 50m across and 50m deep with vertical walls. This pit is of particular interest because it hosts access to a cave entrance at its base, providing an opportunity to monitor cave climate throughout a type of cave structure that is ordinarily inaccessible. In-situ cave climate observations included cold trapping, cave breathing, possible e

This data release presents a compilation of postfire sediment mobilization data from wildfires greater than 100 km2 that occurred in California or regions of southern Oregon that drain to the California coast between 1984 and 2021. This compilation includes three sources of sediment mobilization data: hillslope erosion modeled using the Water Erosion Prediction Project (WEPP) postfire erosion mode

A database of the geologic map of the Katmai Volcanic Cluster as described in the original abstract: This digital publication contains all the geologic map information used to publish U.S. Geological Survey Geologic Investigations Map Series I-2778 (Hildreth and Fierstein, 2003). This is a geologic map of the Katmai volcanic cluster on the Alaska Peninsula (including Mount Katmai, Trident Volcano,

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Staunton 30 x 60 minute quadrangle in West Virginia and Virginia. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2015 and 2021. The data were processed using geographic

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Buena Vista 30 x 60 minute quadrangle in Virginia and West Virginia. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2017 and 2021. The data were processed using geograph

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Front Royal 30 x 60 minute quadrangle in West Virginia and Virginia. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs) and lidar point cloud (LPC). The lidar source data were compiled from different acquisitions published between 2014 and 2021. The data w

The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 2-mile reach of the Middle Green River at Grays Canyon near Green River, UT. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et. al. 2021) using Agis

Data release includes the U.S. Geological Survey (USGS) estimate of spring nitrogen fluxes summed from nine tributaries to the Chesapeake Bay from 1985 to 2023. Data are presented as the sum from tributaries within the USGS River Input Monitoring (RIM) network identified by site numbers: 01491000, 01578310, 01594440, 01646580, 01668000, 01673000, 01674500, 02035000, 02041650.

This data release contains soil and vegetation data collected along a post glacial chronosequence associated with populations of oriental bittersweet (Celastrus orbiculatus) at the Indiana Dunes National Park. The post glacial chronosequence includes sand dunes and moraines, representing a successional gradient from woodland transition, to oak savanna, woodland and forest, to oak hickory forests o
