A comprehensive study to evaluate salinity and nutrient conditions in the Heart River Basin, North Dakota was completed by the U.S. Geological Survey (USGS) in cooperation with the Natural Resources Conservation Service and the Grant County Soil Conservation District. In this dataset three zipped folders are provided which contain all files necessary to run trend, load, and geochemical models and produce results published in U.S. Geological Scientific Investigations Report 2022-5013 [Tatge, W.S., Nustad, R.A., and Galloway, J.M., 2022, Evaluation of Salinity and Nutrient Conditions in the Heart River Basin, North Dakota, 1970-2020: U.S. Geological Survey Scientific Investigations Report 2022-5013]. In addition,...

In November 2016, the U.S. Geological Survey acquired high-resolution P- and S-wave seismic data across the surface trace of the West Napa Fault zone near Buhman Avenue in Napa, California. We acquired seismic reflection, refraction, and guided-wave data along a 117-m-long profile across the known surface rupture zone of the West Napa Fault zone. To acquire the reflection and refraction data, we co-located shots and geophones, spaced every meter along the profile. We used 118 SercelTM L40A P-wave (40-Hz vertical-component) geophones with a sensitivity of 22.34 volts/meter/second to record 118 P-wave shots. We also used 118 SercelTM L28-LBH S-wave (4.5-Hz horizontal-component) geophones with a sensitivity of 31.3...

These produced datasets include water-quality and quality assurance results collected by the USGS and other entities from 1952 to 2016 near the City of Poplar as well as throughout the East Poplar oil field, leachate results collected from drilling core within the Cretaceous Bearpaw Formation and Monoammonium phosphate (MAP) fertilizer results collected by the USGS in 2012. The handling and disposal of the brine has resulted in contamination of not only the shallow aquifers in the East Poplar oil field, but also the Poplar River (Thamke and Craigg, 1997; Thamke and Smith, 2014). The shallow aquifers are the only available source of potable groundwater in the area, and had provided water for more than 100 residents...

Information on the spatio-temporal distribution of rainfall is critical for addressing water-related disasters, especially in the Middle East and North Africa's (MENA) arid to semi-arid regions. However, the availability of reliable rainfall datasets for most river basins is limited. In this study, we utilized observations from satellite-based rainfall data, in situ rain gauge observations, and rainfall climatology to determine the most suitable precipitation dataset in the MENA region. First, we evaluated seven different rainfall products (CPC, GPCC, TRMM, PERSIANN, RFE, CHIRPS, MSWEP) using rain gauge observations obtained from Jordan (139 stations), Palestine (9 stations), and Lebanon (16 stations). The validation...
