Soil and groundwater concentrations of PFAS, soil properties, and derived soil-water distribution coefficients for sites in Maine Soil and groundwater concentrations of PFAS, soil properties, and derived soil-water distribution coefficients for sites in Maine
The U.S. Geological Survey (USGS) derived soil-water distribution coefficients (Kd values) from per- and polyfluoroalkyl substances (PFAS) analytical chemistry data and soil properties based on soil and groundwater samples collected by the Maine Department of Environmental Protection between 2019 and 2024. Samples were collected at agricultural biosolid application sites in Maine. At...
Nodal Seismometer Recordings along a San Francisco Peninsula DAS array, Stanford to Redwood City, California Nodal Seismometer Recordings along a San Francisco Peninsula DAS array, Stanford to Redwood City, California
In February 2026, the U.S. Geological Survey deployed a nodal seismometer array along a portion of a distributed acoustic sensing (DAS) array extending from Stanford to Redwood City, California. Seismic data were acquired using 33 DTCC SmartSolo, IGU-16HR 3-component nodal seismometers ("nodes"), which continuously recorded for approximately one month. By combining the DAS observations...
Nodal Seismometer Recordings of Aftershocks of the 5 May 2023 M 5.5 Lake Almanor, California Earthquake Sequence Nodal Seismometer Recordings of Aftershocks of the 5 May 2023 M 5.5 Lake Almanor, California Earthquake Sequence
At 4:19 pm local time on 11 May 2023, a M 5.5 earthquake occurred beneath Lake Almanor, California, located in Lassen National Forest about 180 km north-northeast of Sacramento, California. Shortly afterward, the United States Geological Survey deployed 34 DTCC SmartSolo IGU-16HR nodal seismometers ("nodes") in the region surrounding Lake Almanor. Each node recorded 3-component motion...
Aerial imagery and Structure-from-Motion products for a UAS survey collected on 05-10-2024, White Slough tidal wetland restoration project, Humboldt Bay, California Aerial imagery and Structure-from-Motion products for a UAS survey collected on 05-10-2024, White Slough tidal wetland restoration project, Humboldt Bay, California
This data release presents aerial imagery and structure-from-motion digital products from a UAS survey of the White Slough tidal wetland restoration project, conducted in cooperation with the California State Coastal Conservancy and the U.S. Fish and Wildlife Service - Humboldt Bay Refuge. The tidal wetland restoration project aimed to restore subsided land to an ecologically functional...
Photographs and hydrographic survey data from longitudinal river surveys of Willamette River tributaries, 2022 and 2023 Photographs and hydrographic survey data from longitudinal river surveys of Willamette River tributaries, 2022 and 2023
In 2022 and 2023, the U.S. Geological Survey (USGS) conducted longitudinal photographic and hydrographic surveys of major tributaries to the Willamette River in the Cascade Range, Oregon. These surveys integrated simultaneous above-water 360-degree photographs, underwater photographs, high-accuracy Global Navigation Satellite System (GNSS) positioning measurements, and single-beam sonar
2018 digital elevation models of karst areas in Puerto Rico at 3-meter resolution 2018 digital elevation models of karst areas in Puerto Rico at 3-meter resolution
This raster dataset contains 3-meter digital elevation models (DEMs) of 7.5 minute quadrangles in karst areas of Puerto Rico and was created using GlobalMapper v.23 software. These DEMs were derived from 1-meter DEM tiles acquired through the USGS 3D Elevation Program (3DEP). The data are projected in North America Datum (NAD) 1983 (2011) UTM Zone 19N.
Pellet Transects in Glacier National Park, 2020-2022 Pellet Transects in Glacier National Park, 2020-2022
Pellet transects were conducted from 2020 to 2022 at grassland sites where vegetation surveys were conducted by Glacier National Park biologists. The field work consisted of counting wildlife fecal pellets along transects to learn more about elk use and possible wildlife effects on vegetation. This information provides a baseline to evaluate changes in elk distributions after bison...
Structure from Motion orthomosaic of Vicksburg National Military Park in Vicksburg, MS created from 1962 aerial imagery Structure from Motion orthomosaic of Vicksburg National Military Park in Vicksburg, MS created from 1962 aerial imagery
The dataset is a 0.5 m spatial resolution panchromatic (black and white - B&W) orthomosaic of northern Vicksburg, MS and Vicksburg National Military Park in 1962. It was created using structure from motion-aided photogrammetry techniques in Agisoft Metashape (v 2.1.1). The aerial images were acquired on February 10, 1962 by the U.S. Department of Agriculture at approximately 1:18,000...
Data describing H5N1 Avian Influenza Infection and Exposure in Sandhill Cranes wintering in Staten Island, California Data describing H5N1 Avian Influenza Infection and Exposure in Sandhill Cranes wintering in Staten Island, California
We sampled 31 Greater and two Lesser Sandhill Cranes (Antigone canadensis tabida and Antigone canadensis canadensis, respectively) wintering in California’s Central Valley during the 2023 - 2024 and 2024 - 2025 seasons to assess active infection with IAV.
Gamma-ray spectrometry measurements in the Brallier, Foreknobs, and Hampshire Formations, Baker, West Virginia Gamma-ray spectrometry measurements in the Brallier, Foreknobs, and Hampshire Formations, Baker, West Virginia
This dataset includes gamma-ray spectrometry measurements from exposed Devonian-aged heterolithic siliciclastic strata of the Brallier, Foreknobs, and Hampshire Formations. Gamma-ray measurements were collected using a continuous assay mode with a 30-second collection interval while walking approximately one to two meters from the outcrop face using the GF Instruments Gamma Surveyor...
