Data Releases

In June of 2020, the U.S. Geological Survey conducted a high-resolution seismic survey at Edwards Air Force Base in Kern County, California. Seismic data were acquired using a DTCC SmartSolo 3-component nodal seismometer system ("node"), which continuously recorded at 2000 samples per second. Nodes were deployed 5 meters apart along a southwest-northeast trend to create an approximately 3-km-long

These raster and tabular data were compiled to develop time series data of the lower Colorado River (LCR) vegetation greenness, water use, and phenology since the year 2000. An objective of our study was to evaluate short and long-term effects of drought and biocontrol on LCR riparian and aquatic ecosystems south of Hoover Dam. These data represent spatially explicit average Enhanced Vegetation In

This data release is a repository for data presented in Anderson and Shean (2021), a publication looking at topographic change in proglacial and glacier-marginal areas on Mount Rainier between 1960 and 2017. Datasets include all newly derived digital elevation models, shapefiles defining various areas of analysis, and tabular summaries of data presented in figures. See individual child items and o

This U.S. Geological Survey (USGS) Data Release is focused on the geochemistry of wastewater (including flowback and produced water) samples, co-produced with natural gas, collected from the Marcellus Shale Energy and Environment Laboratory (MSEEL) site. MSEEL is a long-term field site and laboratory at the Northeast Natural Energy LLC (NNE) production facility, adjacent to the Monongahela River,

Data represent a comparison of herding techniques commonly used by natural resource agencies and the public to increase removal or harvest of invasive carp (i.e., Silver Carp) from U.S. waterways. Sites on lower Perche Creek, Columbia, MO (2018 August 9th to 2018 October 26th) were contained using block nets and treated with one of five herding techniques: (1) method commonly used by commercial fi

This dataset documents the onset of developmental stages of pallid sturgeon free embryos from hatch through melanin plug expulsion, when reared in the laboratory at five nominal temperatures (14, 17, 20, 23, and 26 degrees Celsius, degrees C). Onset of developmental stages were recorded in days post-hatch (DPH) and cumulative thermal units (CTU). CTU are calculated as the sum of water temperature,

The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify bathymetric changes along the Florida Reef Tract (FRT) from Miami to Key West within a 939.4 square-kilometer area. USGS staff calculated changes in seafloor elevation and volume from 2016 to 2019 using light detection and ranging (lidar)-derived digital elevation models (DEMs) acquire

In cooperation with Dallas Water Utilities (DWU), the U.S. Geological Survey (USGS) measures nutrient and major-ion concentrations in selected reservoirs in north Texas. This data release documents the results from water-quality samples collected from Ray Hubbard Lake, Grapevine Lake, Ray Roberts Lake, and Lake Lewisville during 2016 -18. The study began in water year 2016 (WY16) with monthly samp

The U.S. Geological Survey (USGS) compiled data from a variety of national and state agencies to create a comprehensive dataset of streamflow and stage for the lower Columbia River basin and the coasts of Washington, Oregon, and northern California. Seasonal maximum values were calculated for streamflow and stage for the winter (November-March) and spring (April-July) flow seasons, as well as for

Water supply lakes are the primary source of water for many communities in northern and western Missouri. Therefore, accurate and up-to-date estimates of lake capacity are important for managing and predicting adequate water supply. Many of the water supply lakes in Missouri were previously surveyed by the U.S. Geological Survey in the early 2000s (Richards, 2013) and in 2013 (Huizinga, 2014); ho

Groundwater in the Big Lost River Basin is vital to irrigated agriculture in the basin and water users are concerned about declining groundwater levels. The U.S. Geological Survey, in cooperation with the Idaho Department of Water Resources, developed a hydrogeologic framework to provide a conceptual understanding of groundwater resources in the Big Lost River Basin. A three-dimensional hydrogeolo

These data are in nine tables relating to three species of arctic breeding geese studied on the Colville River Delta, Alaska, 2011-2014. The tables provide: 1-2) spring migration and arrival dates, 3) pre-nesting intervals, 4) nest initiation dates, 5) goose esophageal contents, 6) egg stable isotope ratios, 7) goose tissue stable isotope ratios, 8) forage plant stable isotope ratios, and 9) egg e
