Data

This dataset contains results from three stratigraphic sections of the Hue Shale located in and adjacent to the Arctic National Wildlife Refuge in northeastern Alaska. Sample heights were measured with a tape measure in continuous successions. Zircon grains from volcanic ashes were analyzed via laser ablation at the University of California, Santa Barbara (UCSB) using a Photon Machines...

These tabular data are the summarization of land use/land cover related variables within the Delaware River watershed at the 1:24,000 scale using the xstrm methodology. Variables being counted as land use/land cover related include all land use and land cover data. Outputs consist of tabular comma-separated values files (CSVs), and parquet formatted files for both the local catchment and...

These tabular data are the summarization of natural environment related variables within catchments of the Delaware River watershed at the 1:24,000 scale using the xstrm methodology. Variables being counted as natural environment related include soils/geology, lithology, elevation, slope, landform (geomorphon) and others. Outputs include tabular comma-separated values files (CSVs) and...

American pikas (Ochotona princeps) are small lagomorphs that live in mountainous talus areas of western North America. Studies on the histopathology of American pikas are limited. This report summarizes the clinical histories, and gross and histologic findings of 12 American pikas, including nine captive and three wild animals. Death was often attributed to stress (transport, handling...

The released data contain both a csv and parquet file summarizing the Centers for Disease Control (CDC) Social Vulnerability Index (SVI), at the NHDPlus V2 stream catchment scale. Dasymetric mapping was utilized to bound 2014 populations to the 2013 National Land Cover Dataset and then trim them to NHDPlus V2 catchments. These produced data are summarized as numbers of people within each...

During an epidemiologic survey following a mortality event of freshwater mussels in 2018 in the Embarrass River, Wisconsin, USA, we identified a novel microsporidian parasite in the ovary of mucket (Actinonaias ligamentina), plain pocketbook (Lampsilis cardium), and fatmucket (Lampsilis siliquoidea) (Unioinidae). Histopathology showed round-to-oval microsporidial spores in the cytoplasm...

U.S. Geological Survey (USGS) scientists conducted field data collection efforts between October 25th and 31st, 2020 at several sites in eastern Iowa using high accuracy surveying technologies. The work was initiated as an effort to validate commercially acquired topographic light detection and ranging (lidar) data that was collected between December 7th, 2019 and November 19th, 2020...

The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) program, through its Long Term Resource Monitoring (LTRM) element, collected aerial imagery of the systemic Upper Mississippi River System (UMRS) during the summer of 2020. A Land Cover/Land Use (LCU) spatial database was developed based on the 2020 aerial imagery, which adds a fourth systemic-wide database to...

This U.S. Geological Survey (USGS) data release provides surface water quality and groundwater elevation data collected by USGS personnel within the Central Pine Barrens (CPB) Region of Suffolk County, New York, from October 1, 2021 through September 30, 2022. The data were collected in cooperation with the Central Pine Barrens Commission and the Town of Brookhaven as part of a...

The U.S. Geological Survey (USGS) California Water Science Center (CAWSC) Organic Matter Research Laboratory (OMRL) provides laboratory services and support to regional and national projects in the analysis of organic matter using the latest methods in absorbance and fluorescence spectroscopy. Optical measurements such as absorbance and fluorescence are used to gain insight into...

The 1966-2023 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...
