Data

This U.S. Geological Survey (USGS) Data Release provides phytoplankton data for samples collected from twelve large river sites throughout the United States, from June through October 2019. All data are reported as raw calculated values and are not rounded to USGS significant figures. The dataset includes all routine and quality assurance/quality control samples collected as part of a National Wat

These datasets contain all publicly available analytical data collected by the U.S. Geological Survey (USGS) at each location sampled by the Pennsylvania Pesticides in Vulnerable Groundwaters program from 2021 and 2022. Additional analytical data will be appended following the conclusion of each sampling season, and all data is made publicly available in the on-line National Water Information Syst

This USGS data release represents the data from the following 2013 publication: Plume, R.W., and Smith, J.L., 2013, Properties of basin-fill deposits, a 1971–2000 water budget, and surface-water-groundwater interactions in the upper Humboldt River basin, northeastern Nevada: U.S. Geological Survey Scientific Investigations Report 2013-5077, https://doi.org/10.3133/sir20135077.

This data release serves as an archive of coastal land-cover and feature datasets derived from Landsat satellite imagery from Delaware Bay, New Jersey (NJ) to Shinnecock Bay, New York (NY). A total of 119 images acquired between 2008 and 2022 were analyzed to produce 143 thematic land-cover raster datasets. Water, bare earth (sand), and vegetated land-cover classes were mapped using (1) successive

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board collected produced water and gas samples in the Midway-Sunset, Poso Creek, and Buena Vista Oil Fields in Kern County in 2020 and 2021. Sampled sites included oil wells; injectate from tanks, pipelines, and injection wells where produced water from many wells, after removal of oil, is stored or

This dataset provides cycle threshold (Ct) values achieved during qPCR for 6 sex-linked genes, and two autosomal genes, for individuals from 60 species and across 13 orders of birds.

The dataset includes daily counts of the number of independent photo detections from camera traps for 15 mammal species. The camera traps were placed in three study reaches of the Elwha River, Washington between July 2021 and July 2023. The dataset also includes information about the camera station locations, and the calendar date and season when the photos were captured.

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot and Evangeline aquifers (undifferentiated), and Jas

This dataset documents depth to groundwater measurements made from wells screened in the Chicot aquifer, Evangeline aquifer, Jasper aquifer, Burkeville confining unit, Catahoula confining unit, or a combination of these hydrogeologic units in the greater Houston area, Texas for 2023. The U.S. Geological Survey (USGS) prepared this dataset in cooperation with the Harris‐Galveston Subsidence Distric

The 35-year-long Puʻuʻōʻō eruption, on the East Rift Zone of Kīlauea Volcano, was the longest volcanic eruption on the Island of Hawaiʻi in the past 100 years (Wright and Klein 2014; Mulliken and others 2023). The eruption, whose vent area was focused at and around Puʻuʻōʻō cone, produced episodic fountaining in its initial few years followed by decades of effusive activity that created an expans

The Alaska Forage Fish Database (AFFD) is a consolidation of survey data from multiple agencies that were sampled via fishing gear and predator diets. The spatial coverage includes the Gulf of Alaska, Bering Sea, Aleutian Islands, Chukchi Sea, and Beaufort Sea. Fish species within the database include Pacific sand lance, Pacific capelin, Pacific herring, juvenile walleye pollock and Pacific cod, m

Measurements of changes in the distance (or length) between monuments are provided. These measurements were made using a two-color Electronic Distance Meter (EDM) that can measure distances between 1 and 10 KM. Nominal precision of these data range from 0.3 mm to 1.0 mm dependent upon the baseline’s length. These measurements were made between mid-1975 to mid-2006. Data in this archive are from ei
