Calculating Effect Of Drought On Groundwater Resources From Space

A group of ASU researchers has been employing the newest space tech, merged with ground calculations, to evaluate the health of one of the country’s most essential underground water sources, a huge aquifer system situated in San Joaquin Valley in California.

The group, made of researchers from School of Earth and Space Exploration comprising Susanna Werth, Chandrakanta Ojha, and Manoochehr Shirzaei, aimed at the latest drought period of San Joaquin Valley, between 2012 and 2015, calculating both aquifer storage loss and groundwater loss. The outcomes of their study have been lately posted in the Journal of Geophysical Research.

With the expectation of offering water resource handlers with enhanced tools to assist keep aquifers healthy, the study group is designing new observation methods to observe storage capacity and groundwater of this essential aquifer in California.

They are employing a unique mixture of data from the GNSS (Global Navigation Satellite System), the NASA GRACE satellites, extensometers, InSAR (Interferometric Synthetic Aperture Radar) from the Sentinel 1 satellite of European Space Agency, and ground level records.

On a related note, water is always controversial, always important, always fascinating, and remains surprising. For a material that is omnipresent on Earth, 3/4th of the Earth is wrapped with it, scientists can still be shocked by some of its characteristics, as per C. Austen Angell, the chemist of Arizona State University.

Angell, an ASU’s School of Molecular Sciences Regents Professor, has invested a good part of his renowned career tracing down some of more inquisitive physical characteristics of water. In a fresh piece of study just posted in Science this week, for the first time Angell and associates from the University of Amsterdam have noticed one of the more fascinating characteristics predicted by water experts. This property is: under particular conditions and on enough super-cooling water will abruptly transform from one liquid to a different liquid.
