Bulk organics and carbonate content of sediment cores from the New England Mud Patch collected on USGS Field Activity 2016-001-FA

Variability in sediment properties with depth and the thickness of individual sedimentary layers are critical determinants of seabed acoustic response. The New England Mud Patch (NEMP), located south of Cape Cod, is an unusual feature on the U.S. Continental Shelf in that it is composed of fine-grained sediment layers containing a relatively-homogeneous mix of sand, silt, and clay-sized particles bounded by more typical sandy shelf sediments.  The unique characteristics and nature of this deposit is due to a derivation of sediments that have been transported to, and deposited in, a basal bowl-shaped depression since the last glacial maximum. Ninety-two piston, vibra-, and gravity cores with a maximum length of 8.2 meters were collected from across the New England Mud Patch during a 2-leg, 10-day cruise aboard the R/V Endeavor in the spring of 2016. Geologic characterization and analysis of a subset of the cores including grain size, CaCO3, mineral composition, and bulk index properties (undrained shear strength, water content, density, and porosity) of discrete samples was carried out at the USGS Woods Hole Coastal and Marine Science Center's (WHCMSC) Sediment Analysis Laboratory. This data release contains the results of these analyses, along with visual core descriptions and summary sheets for each core analyzed for this study.

Estimated equivalent population using public supply groundwater in the conterminous United States, ULUEM

The population using public supply drinking water was mapped in two ways: the census enhanced method (CEM) evenly distributes the population across the census block-group, and  the urban land-use enhanced method (ULUEM) distributes the population only to certain urban land use designations in order to more precisely locate public supply users. This dataset consists of the estimated population using public supply groundwater distributed using the urban land-use enhanced method.

Penobscot River Cross Section Data pre- and post-Dam Removal

The Great Work and Veazie dams on the lower section of the Penobscot River were removed during 2012 to 2013. Channel cross sections adjacent to the dams were surveyed before and after the dams were removed. Data for each cross section include total station theodolite survey data integrated with Acoustic Doppler Current Profiler (ADCP) data referenced from the water surface at the time of the survey to make up integrated cross sections. At the higher flows more data were collected by the ADCP at the edges of the cross sections. There are some gaps in 2009 from where the ADCP data ended and the total station data began.  At the lower flow (2010) these edge data were collected wading with the total station, and the gaps were filled in.

Tritium-helium-3 and tritium-based groundwater-age estimates from analyses of groundwater samples from the Great Miami buried-valley aquifer, southwestern Ohio, 1999, 2000, 2019, and 2020

The U.S. Geological Survey (USGS) in cooperation with the Miami Conservancy District, Dayton, Ohio, in 2019 and 2020 investigated the occurrence of per- and polyfluoroalkyl substances (PFAS) in groundwater from the Great Miami buried-valley aquifer (GM-BVA) of Southwestern Ohio. The 23 wells used for PFAS sampling were identified and sampled previously by the USGS National Water-Quality Assessment Program to assess the occurrence of a variety of inorganic and organic contaminants in the GM-BVA. Data in this release include tritium and tritium-helium based groundwater-age estimates from the same wells sampled for PFAS,as compiled from Hinkle and others (2010) and McMahon and others (2022).  The prior (1999) sampled wells were from parts of the GM-BVA in Butler, Champaign, Clark, Greene, Hamilton, Miami, Montgomery, Shelby and Warren counties in the Great Miami River, Little Miami River, and Whitewater River Basins.
Tritium and its radioactive decay daughter product helium-3 concentrations in prior (1999) groundwater samples from 22 of 23 wells sampled by this study had previously been used to estimate the age of groundwater produced from the GM-BVA since its recharge below the water table (Hinkle and others, 2010).  These estimates of groundwater ages since recharge are based on the potentially limiting assumptions that tracer transport is advective (piston-flow assumptions) and that no mixing occurs in groundwater between its recharge below the water table and where it was withdrawn from each well during sampling (Hinkle and others, 2010). The recharge date relative to samples collected by this study was computed by subtracting the estimated groundwater age in years since recharge (that was computed from the 1999 or 2000 sample) from the year that samples for PFAS analysis was collected for this study from the same wells (2019). Recharge dates estimated from a tritium-based groundwater-age category are also included in this dataset, as computed from tritium concentrations reported from samples collected during the 2019–20 companion USGS National Water Quality Program sampling (McMahon and others, 2022).

Orthomosaic imagery for Whiskeytown Lake and surrounding area, northern California, 2020-11-10

This portion of the data release presents an RGB orthomosaic image of Whiskeytown Lake and the surrounding area derived from Structure from Motion (SfM) processing of aerial imagery acquired on 2020-11-10. The orthomosaic is available in a high-resolution 5-centimeter (cm) version, as well as a medium-resolution 25 cm version. The high-resolution version is divided into two tiles (east and west) to reduce file download sizes. All imagery is provided in a three-band cloud optimized GeoTIFF format, with 8-bit unsigned integer values compressed using high-quality JPEG compression. The raw imagery used to create the orthomosaic image was acquired from a manned aircraft on 2020-11-10. The acquisition flight was conducted by The 111th Group Aerial Photography, using a Hasselblad A6D-100c camera. The imagery was acquired from an approximate altitude of 880 meters (2,900 feet) above ground level, to produce a nominal ground sample distance (pixel size) of 5 centimeters (2 inches). An onboard dual-frequency GPS receiver was used to record the precise time and position of each image. Coordinates for ground control points consisting of photo-identifiable objects were measured independently using survey-grade post-processed kinematic (PPK) GPS.

Topographic digital surface model (DSM) for Whiskeytown Lake and surrounding area, 2020-11-10

This portion of the data release presents a digital surface model (DSM) and hillshade of Whiskeytown Lake and the surrounding area derived from Structure from Motion (SfM) processing of aerial imagery acquired on 2020-11-10. Unlike a digital elevation model (DEM), the DSM represents the elevation of the highest object within the bounds of a cell. Vegetation, buildings and other objects have not been removed from the data. In addition, data artifacts resulting from noise and vegetation in the original imagery have not been removed. However, in unvegetated areas such as reservoir shorelines and deltas, the DSM is equivalent to a DEM because it represents the ground surface elevation. The raw imagery used to create this DSM was acquired from a manned aircraft on 2020-11-10. The acquisition flight was conducted by The 111th Group Aerial Photography, using a Hasselblad A6D-100c camera. The imagery was acquired from an approximate altitude of 880 meters (2,900 feet) above ground level, to produce a nominal ground sample distance (pixel size) of 5 centimeters (2 inches).
