First evidence of planet-wide groundwater system on Mars
Mars Express has revealed the first geological evidence of a system of ancient interconnected lakes that once lay deep beneath the Red Planet’s surface, five of which may contain minerals crucial to life.

South Napa Earthquake linked to summer groundwater dip
A summertime expansion in the Earth’s crust caused by changes in groundwater may have triggered the magnitude-6.0 earthquake in California’s wine country in 2014, according to a new study.

Groundwater recharge in the American west under climate change
Groundwater recharge in the Western U.S. will change as the climate warms–the dry southern regions will have less and the northern regions will have more, according to new research.

Large precipitation events critical in replenishing groundwater resources
Large precipitation events that occur about every 10 years are a critical source of recharge for replenishing groundwater resources, according to a new study. Groundwater is a vital source of water in the western United States and will be increasingly important with continued population growth and climate variability. Understanding the role of these large recharge events in replenishing aquifers and sustaining water supplies is crucial for long-term groundwater management.

Divining water using gravity
Researchers are using technology a tad more sophisticated and scientific than dowsing rods to detect underground water from afar: sensors that measure minuscule changes in gravity.
