Geological sciences researchers at Virginia Tech are using GPS antennas to measure aquifer use and storage capacity. At the Geological Society of Americas 114th annual meeting in Denver, Oct. 27-30, masters degree student Sandra Warner will make the case for the broader coverage of such tools.
Warner and Virginia Tech geological sciences professor Thomas Burbey are conducting a large-scale aquifer test on a new municipal well in the Virgin River Valley near Mesquite, Nev. In addition to the monitoring wells that traditionally surround a pump site, the researchers are using 10 GPS antenna as a new way to measure land subsidence. They also hope to incorporate data from a remote-sensing radar satellite that measures land change.
Traditionally, how much water is in an aquifer is determined by how much the water sinks vertically as it is used. Warner is determining how capacity changes horizontally as well as vertically. As aquifers are emptied, there is shifting to fill the areas emptied of water. The newest GPS antennas will make it possible to measure land subsidence with millimeter accuracy.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
