Yellowstone will study electromagnetic sensors

A new study, which will provide unprecedented views of the earth’s crust under Yellowstone national Park will begin November 7, 2016. Scientists from the USGS, University of Wyoming and the University of Aarhus in Denmark will use aircraft with special sensors electromagnetic (HEM) to accurately set the regions of hot and cold water, steam, clay and unaltered rocks, as well as to better understand the hydrothermal system of Yellowstone. The flights will be conducted within two to four weeks.

Although hot springs and geysers can be seen on the surface of the volcano, their underground structure is poorly understood. The study with the help of HEM, SkyTEM managed company, will provide a new look at subsurface hydrothermal system of Yellowstone and will track mud pots, steam vents and craters of hydrothermal explosions at a depth of over 300 metres.

A low-flying helicopter will travel on pre-planned routes with a focus on the corridor between Mamontovy springs, geyser basin Norris, the Northern part of Yellowstone lake, Upper and Lower geyser basins. Sensitive equipment will record any tiny voltage, which can be associated with electrical conductivity in the ground.

The new observations combined with existing geophysical, geochemical and geological data will help scientists to close a significant gap in the knowledge concerning the hydrothermal system of the Caldera and is located below the magmatic system.
