Operating fish farm from which outflow discharge measurement was made. This fish farm raises sturgeon, trout, and other cold-water fish using groundwater withdrawals from an artesian aquifer in the Ararat Basin. More information about this study is available in https://doi.org/10.3133/sir20175163

Sturgeon raised at fish farm. Water use at this farm is about 5,500 gallons per consumable pound of fish. More information about this study is available in https://doi.org/10.3133/sir20175163.

Hrazdan River at Yerevan, Armenia. Water samples were collected at this site for analyses of various isotopes. More information about this study is available in https://doi.org/10.3133/sir20175163.

Ice jam at the White River near Interior, SD, USGS streamgage 06446500, on February 12, 2016. An ice streamflow measurement was made a few days prior to the ice breakup on Februrary 9, 2016, and was 235 cubic feet per second.

Dr. Dorjsuren (Fresh Water Institute) explains to the U.S. team about water uses in the Tuul River Basin in Ulaanbaatar, Mongolia.

Well house (white building in center of photograph) in the Upper Resource well field about 60 kilometers east of Ulaanbaatar, Mongolia. The Upper Resource supplies the best quality water to Ulaanbaatar because it is upstream from any major development.

Groundwater modeling workshop participants in Ulaanbaatar, Mongolia, with the
U.S. team. Training was delivered to 39 professional hydrogeologist and hydrologists during the Phase I
training. More information on this study is available at https://doi.org/10.3133/ofr20161096.

A Mongolian hydrologist showed a monitoring site where groundwater levels, precipitation, air temperature, soil moisture, and soil temperature data are collected. More information on this study is available at https://doi.org/10.3133/ofr20161096.

A low-flying helicopter will carry this large cylindrical sensor, called a bird, to measure physical properties of the Big Sioux aquifer below the Earth's surface. More information on the airborne electromagnetic method is available at https://doi.org/10.3133/fs20163075.

Power lines present challenges in data collection and analyses of airborne electromagnetic data near Sioux Falls, SD. The bird is suspended from a helicopter as it transmits and receives electromagnetic signals to the ground, which are used to interpret characteristics of the aquifer.

This sensor, called a bird, is tethered to a helicopter during USGS geophysical surveys. As the helicopter flies low over specific areas, the bird transmits electromagnetic waves deep into the ground to measure the below-surface physical properties. This scientific system is called Resolve and is operated by CGG Canada Servives, Ltd.
