Seismic waves are blind to water

Geoscientists use the seismic waves produced by earthquakes to image the internal structure of the planet. Some seismic waves travel through liquids, while others do not, which is how we know, for instance, that Earth has a solid inner core and a liquid outer core.

Diamonds reveal water in deep mantle

Inclusions in diamonds often render them undesirable to consumers, but they can provide researchers with striking insights into Earth’s composition. Recently, scientists probing diamond samples for the presence of carbon dioxide stumbled instead upon inclusions of ice-VII — a type of crystallized water that forms at very high pressures, and has never before been found in nature.

"Greening" stormwater in Philadelphia

When environmental geologist David Wilcots joined Sci-Tek Consultants in 2014, he became involved with the Philadelphia Water Department’s Green Stormwater Infrastructure project. Sci-Tek’s goal was to redesign certain areas of the city’s urban landscape so that “less stormwater goes into the sewage system” and more goes into the ground, explains Wilcots.

Beavers preserve wetlands in water-stressed areas

Once considered detrimental to ecosystems and nuisances where, for example, dams flooded farmland, beavers have been rhetorically touted in recent years as a potential boon for wetland health and water conservation. Anecdotal accounts and qualitative findings have suggested beavers improve water quality and availability in drought-stressed ecosystems, but just how much influence they have was not known. In new research, scientists have examined two creeks in Nevada to directly measure how effective beaver dams are at slowing water flows and storing water through the dry summer months.

Evidence of devastating drought found beneath the Dead Sea

The Dead Sea, a landlocked lake bordered by Israel, Jordan and Palestine, is nearly 10 times saltier than the ocean. And it’s getting saltier. Since the beginning of the 20th century, the water level has dropped by nearly 30 meters, largely because of diversions of the Jordan River, the lake’s primary tributary and the arid region’s main source of fresh water.
