Geospatial datasets developed for a hydrogeologic conceptual model of brine discharge to the Dolores River, Paradox Valley, Colorado Geospatial datasets were developed to estimate the altitude of the top of bedrock, altitude of the top of the Paradox salt, altitude of the water table in the alluvial aquifer, and the thickness and extent of saturated alluvium in the Paradox Valley in western Colorado. This study was completed by the U.S. Geological Survey (USGS) in cooperation with the Bureau of Reclamation for modeling of brine discharge to the Dolores River (Heywood and others, 2024; Paschke and others, 2024). One point dataset and 11 surfaces (shapefiles or rasters) are published in this data release. The point dataset (Paradox_well_data.zip) contains water-level and geologic data for groundwater, observation, test, and production wells in...

The airborne survey was jointly funded by the Earth Mapping Resources Initiative and the Wyoming State Geological Survey (WSGS). The survey was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 16,400 line km of magnetic and radiometric data were acquired over an irregular-shaped area of 2710 km2. Data were collected from a helicopter flown at a nominal terrain clearance of 80 meters (m) above topography along N-S flight lines spaced at 200 m intervals. The line spacing...

Large strike slip faults in the region include the San Andreas fault, the Maacama fault, the Bartlett Springs fault among many others. In areas where strike slip fault geometry changes, either in restraining or releasing bends, vertical motion may occur in response to dominant right-lateral deformation. Channel steepness and chi data may be used to identify areas of recent uplift where the bedrock hardness and local precipitation gradients are known.

The U.S. Geological Survey (USGS) installed acoustic bedload monitoring systems at four sites along the Trinity River below Lewiston Dam to record the noise generated by mobilized bed material, known as sediment generated noise (SGN) (Geay and others, 2017). The four sites are: Trinity River at Lewiston (TRAL, 11525500), Trinity River above Grass Valley Creek (TRGVC, 11525630), Trinity River at Limekiln Gulch (TRLG, 11525655) and Trinity River at Douglas City (TRDC, 11525854). These sites were selected because bedload measurements are frequently made at these locations during restoration flows as part of monitoring done by the Trinity River Restoration Program (TRRP). Monitoring took place in the spring of 2015,...

The model was used to simulate the impact of sea level rise (SLR) on these coastal cover classes, with an emphasis on wetlands, for the “Evaluation of Regional SLAMM Results to Establish a Consistent Framework of Data and Models” project. The project was performed by Warren Pinnacle Consulting, Inc., and Image Matters LLC. The project was funded by the Gulf Coast Prairie Landscape Conservation Cooperative (LCC).

USA (ver. 5.0, June 2024) The Hamilton Wetland Restoration Project (HWRP) is a joint venture between the US Army Corps of Engineers (USACE; San Francisco District) and the California State Coastal Conservancy. The site is located on the property of the former Hamilton Army Airfield in Novato, California, along the western edge of San Pablo Bay, which is part of northern San Francisco Bay. The initial stages of wetland restoration, which included dredged sediment reuse, took place during 2009–2011. From 2011 until April 2014, the site was maintained as partially flooded through a temporary one-way culvert that allowed bay water onto the site. On April 25th, 2014, the outboard levee towards the north-eastern corner of the site was breached...

Japanese quail (Coturnix japonica) were exposed to multiple doses of HBCD over multiple generations through feed and by maternal deposition into the egg. Liver transcriptomes were examined to identify genes and pathways directly affected by HBCD to better understand the mechanisms of action in birds. RNA was extracted from liver of adults and embryos and analyzed (1x50 bp) on an Illumina HiSeq 2000.

Mitogenomic analyses of Arctic cod and three other co-distributed gadoids (Polar cod [Arctogadus glacialis], Saffron cod [Eleginus gracilis], Walleye Pollock [Gadus chalcogrammus]) were also completed. Transcriptomic analyses of Arctic cod were used to identify genes associated with environmental perturbations. Genome-wide scans using RAD-Seq of Arctic cod and the co-distributed Polar Cod were collected.
