The U.S. Geological Survey, in cooperation with the Minnesota Pollution Control Agency, conducted a study to determine the occurrence of micropollutants in: (1) shallow groundwater near large subsurface treatment systems and rapid infiltration basins and (2) shallow groundwater and soil from an agricultural field that land applies domestic wastewater. Water samples were analyzed with enzyme linked

This dataset includes the magnetotelluric (MT) sounding data collected in 2005 along an east-west profile north of Wells, Nevada. It is important to know whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province. It is also

Between 2005 and 2010, 61 adult female elk were trapped using a baited corral trap on Fossil Butte National Monument during winter. An additional 12 female elk were darted from a helicopter during the winter of 2007 near Cokeville, WY, located approximately 20 km northwest of the Monument. We affixed all elk with GPS collars programmed to collect location data every 5 hours. In total we collected

These data document cause of death determination for stranded otters salvaged from the coast of Washington state and northern Oregon for post-mortem analysis.

On September 25, 1998, SIAL Gosciences Inc. (SIAL) was awarded Department of Interior, contract 98CRCN1018, by the U.S. Geological Survey. This contract required SIAL to carry out a high-sensitivity magnetic and electromagnetic helicopter survey over one block located in the Eureka Graben Area near Silverton, Colorado. The primary goal of this project was to provide digitally recorded and processe

With increasing concerns about the impact of warming temperatures on water resources, more attention is being paid the relationship between runoff and precipitation, or runoff efficiency. Temperature is a key influence on Colorado River runoff efficiency, and warming temperatures are projected to reduce runoff efficiency. Here, we investigate the nature of runoff efficiency in the upper Colorado R

A major challenge of wildlife telemetry is choosing an attachment technique that maximizes transmitter retention while minimizing negative side effects. For waterbirds, attachment of transmitters with subcutaneous anchors has been an effective and well-established technique, having been used on >40 species. This method was recently modified to include a second subcutaneous anchor, presumably incre

The Mississippi Alluvial Plain (MAP) has become one of the most important agricultural regions in the US, and it relies heavily on a groundwater system that is poorly understood and shows signs of substantial change. The heavy use of the available groundwater resources has resulted in significant groundwater-level declines and reductions in base flow in streams within the MAP. These impacts are li

Data files in this data series represent migrating bird count and habitat information collected during 1989, 1991, 1993, and 1994 field seasons at 13 riparian sites along the San Pedro River and its tributaries in southeastern Arizona, USA. At each site observations were made at up to 20 points, separated by 100 m arrayed along the riparian zone. Observation periods started at 20 minutes after sun

Selected evapotranspiration data were collected from 7/5/2011 to 1/1/2017 at the Amargosa Desert Research Site (ADRS, https://nevada.usgs.gov/adrs/) in support of ongoing research to improve the understanding of hydrologic and contaminant-transport processes in arid environments. The data presented in this data release includes 30-minute and daily evapotranspiration and associated energy-balance f

This dataset includes spatial locations in the Pacific Northwest where streamflow observations were recorded. For the purpose of this investigation, all streamflow observations were converted into wet or dry indicator values.

Heavy rainfall occurred across Louisiana, Texas, Arkansas, and Mississippi in March, 2016 as a result of a slow-moving southward dip in the jet stream funneling tropical moisture into parts of the Gulf Coastal States and the Mississippi River Valley. The storm caused major flooding in the northwestern and southeastern portions of Louisiana and in eastern Texas. Flooding also occurred in the Missi
