Peer-Reviewed Publication

Twenty-eight major U.S. cities, including New York, Dallas, and Seattle, are seeing urban areas sink by 2 to 10 millimeters per year, according to new research from Virginia Tech. The major cause is groundwater extraction. Published in Nature, the study used satellite-based radar measurements to create high-resolution maps of subsidence, or sinking land, for 28 of the most populous U.S. cities. The cities are home to 34 million people, about 12 percent of the total U.S. population.

The quest for Martian water: seismic velocity anomalies suggest liquid water at depth

Science China Press
Peer-Reviewed Publication

In a paper published in National Science Review, an international team of scientists provides seismic evidence of liquid water located 5.4 to 8 kilometers beneath the Martian surface. This water may originate from the ancient ocean that once existed on Mars, which was sequestered into the crust as the planet transitioned to a colder and drier climate during the Amazonian period (beginning ~3 billion years ago).
