Seepage meters measurements were collected at three locations along the northern shoreline and at three locations along the southern shoreline of Crystal Lake, located in the City of Crystal Lake, Illinois on October 28-30, 2020, and November 4-5, 2020. Seepage measurements directly measure the flux for the area captured by the seepage meter. A positive (gaining) flux is assumed when the volume in the collection bag increases and negative (losing) if the volume decreases and the data can also be used to calculate the vertical hydraulic conductivity. The data provided contains the measurements collected at each location and calculations of discharge and flux at each of the seepage meters.

The storage assessment unit (SAU) is the fundamental unit used in the National Assessment of Geologic Carbon Dioxide Storage Resources project for the assessment of geologic CO2 storage resources. The SAU is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the assessment interval. Individual SAUs are defined on the basis of common geologic and hydrologic characteristics. The resource that is assessed is the mass of CO2 that can be stored in the technically accessible pore volume of a storage formation. The technically accessible storage resource is one that may be available using present-day geological and engineering knowledge and technology for CO2 injection...

This data release contains reference baselines for primarily open-ocean sandy beaches along the west coast of the United States (California, Oregon and Washington). The slopes were calculated while extracting shoreline position from lidar point cloud data collected between 2002 and 2011. The shoreline positions have been previously published, but the slopes have not. A reference baseline was defined and then evenly-spaced cross-shore beach transects were created. Then all data points within 1 meter of each transect were associated with each transect. Next, it was determined which points were one the foreshore, and then a linear regression was fit through the foreshore points. Beach slope was defined as the slope...

In coastal areas of the United States, where water and land interface in complex and dynamic ways, it is common to find concentrated residential and commercial development. These coastal areas often contain various landholdings managed by Federal, State, and local municipal authorities for public recreation and conservation. These areas are frequently subjected to a range of natural hazards, which include flooding and coastal erosion. In response, the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data to calculate rates of shoreline change along the conterminous coast of the United States, and select coastlines of Alaska and Hawaii, as part of the Coastal Change Hazards priority...

This dataset includes photographic images of thin sections created from hand samples and drill core from the Stillwater Complex, Montana, along with a shapefile representing the locations of the underground samples and drill hole collars. The samples were collected and core was drilled in order to define platinum-group element resources associated with the J-M Reef at the Stillwater Mine in the Stillwater Complex. The images of the entire thin section, both in plane- and cross-polarized light, were taken using a high-resolution digital camera on a macro stand. The data in each zip file is organized into a folder containing the 'RAW' unprocessed .CR2 images (when available) and associated .xmp metadata files, and...

This USGS data release contains the regional potentiometric contours representing the regional potentiometric surface for Clark County, Nevada, 2009-2015. Contours represent the groundwater-level altitude with a 250-foot contour interval and were created from groundwater elevations from 58 wells and surface elevations from 5 springs.

The U.S. Geological Survey (USGS), in cooperation with the National Marine Sanctuary Program of the National Oceanic and Atmospheric Administration (NOAA), has conducted seabed mapping and related research in the Stellwagen Bank National Marine Sanctuary (SBNMS) region since 1993. The interpretive datasets and source information presented here are for quadrangle 5, which is one of 18 similarly sized segments of the 3,700 square kilometer (km2) SBNMS region. The seabed of the SBNMS region is a glaciated terrain that is topographically and texturally diverse. Quadrangle 5 includes the shallow, rippled, coarse-grained sandy crest and upper eastern and western flanks of southern Stellwagen Bank, its fine-grained sandy...

This digital vector dataset represents the Northern Nevada Rift as published in an article describing the relationship of epithermal gold deposits to large-scale fractures in Northern Nevada (Ponce and Glen, 2002). The data are represented on figures 1-5 in the source publication and were later provided in an Esri shapefile via written communication from D.A. Ponce in 2017. An attribute field was added to distinguish the northern Nevada rift-east, northern Nevada rift-central, and northern Nevada rift-west.
The ability of formalin, PEROX-AID® (hydrogen peroxide), and seawater to kill waterborne Nanophyetus salmincola cercariae was evaluated in vitro. Newly emerged waterborne cercariae survived for extended periods in freshwater, with 50-74% survival occurring in negative control groups after 24 hr. Exposure to dilutions of formalin reduced this survival time, with 0% of cercariae surviving after 30 min. in 167 ppm, 40 min. in 83 ppm, and 180 min. in 42ppm. Exposure to PEROX-AID® (hydrogen peroxide) for one hour resulted in reduced cercariae survival (16.4%) only at the highest concentration (100 ppm), compared to 100% survival in the untreated controls and all lesser concentrations. Dilutions of seawater resulted in...

This dataset contains polygons representing deposits of hyaloclastic debris that were generated between about 3.5 and 3.0 million years ago when a series of basaltic lava flows entered the canyon of the ancestral Columbia River. The lava flows were erupted from volcanoes in the area of the Hood River graben of McClaughry and others (2012), generally have low-potassium tholeiitic basalt composition, and were part of a widespread pulse of mafic volcanism in the northern Oregon Cascade Range that occurred between about 4.4 and 2.1 million years ago (Conrey and others, 1996). Lava flows that entered the ancestral Columbia River were rapidly chilled and fragmented during interaction with water (Trimble, 1963, Swanson,...
