This data release features two digitized historical shorelines for the Mississippi (MS) and Alabama (AL) coastline (Pascagoula, MS to Point aux Pins, AL) from 2010 and 2012. The shorelines were heads-up digitized using ArcMap 10.3.1 from 0.5-meter (m) resolution orthorectified aerial photos sourced from the City of Mobile, Alabama (http://maps.cityofmobile.org/gis/gisdata_order.aspx) and 1-m resol

The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set o

Reproductive Data for All Nests Monitored; Data for Mayfield Analysis; Eggshell thickness, nestling morphological measurements, nestling plasma stable isotopes, and nestling red blood cell oxidative DNA damage; Egg organochlorine pesticide, total PCB, flame retardants, and PCB toxic equivalent concentrations; Fish capture by osprey; Fish pools and size for contaminant analysis; Fish organochlorine

Ar/Ar data are reported from minerals and rocks that were collected as part of a mineral resource investigation of the Tonopah, Divide, and Goldfield districts in Nevada. Data are reported from 92 samples and associated standards from eight separate neutron irradiations in the Denver USGS TRIGA reactor, including separated mineral grains and whole rocks. Data were collected by infrared laser heati

Analysis of organochlorine pesticides and polychlorinated biphenyls (PCBs) in northern cardinal eggs from six neighborhoods near Washington, DC

In situ recovery (ISR) uranium mining is a technique in which uranium is extracted by a series of injection and recovery wells developed in a permeable sandstone host rock. Chemical constituents (lixiviants) are added to groundwater injection wells to mobilize uranium into groundwater. Before mining, baseline water quality is measured by sampling groundwater from the aquifer intended to be mined a

We developed the HyCReWW metamodel to predict wave run-up under a wide range of coral reef morphometric and offshore forcing characteristics. Due to the complexity and high dimensionality of the problem, we assumed an idealized one-dimensional reef profile, characterized by seven primary parameters. XBeach Non-Hydrostatic was chosen to create the synthetic dataset and Radial Basis Functions implem

Data were collected to evaluate the efficacy of quantitative polymerase chain reaction (qPCR) as a rapid, alternative method for monitoring recreational water at select beaches and rivers of Sleeping Bear Dunes National Lakeshore (SLBE), in Empire, Michigan. Water samples were collected between August 4 and September 18, 2014 (N=297) from four locations (Esch Rd, Otter Creek, Platte Bay, and Platt

This dataset contains shapefiles and associated metadata for lava flows erupted at Kilauea volcano from ca. 1790 through 1982. The dataset includes all known subaerial eruptions in the volcano's Southwest Rift Zone and East Rift Zone, and selected flows erupted within the summit caldera, during this time period. Two attributed shapefiles are associated with each eruption: a polyline shapefile for

Elevation (masl) of groundwater as measured from wells at the USGS Cottonwood Lake Study Area in North Dakota, 1978-2017.

Data collected from April 2014 through September 2016 were used to assess geomorphic characteristics and geomorphic changes over time in a selected reach of Tenmile Creek, a small rural watershed near Clarksburg, Maryland. Longitudinal profiles of the channel bed, water surface, and bank features were developed from field surveys. Changes in cross-section geometry between field surveys were docume

Bravo Dome is a commercial natural CO2 field that supplies the gas to depleted oil fields for enhanced oil recovery. In order to understand the distribution of CO2 across the greater Bravo Dome region, including southeastern Colorado and northwestern New Mexico, and to assess the impacts of high CO2 concentrations on microbes in the subsurface, 7 samples were collected from sites associated with h
