Enceladus' extremely alkaline underground ocean

Saturn’s moon Enceladus is home to a vast underground ocean that erupts to the surface at the moon’s south pole in a giant plume of gas, ice and dust. Scientists studying observational data of this plume collected by the Cassini spacecraft, which has been orbiting Saturn since 2004, have recently learned more about the chemistry of Enceladus’ hidden ocean.

Travertine buildup reflects ancient Rome's water usage

By the third century, Rome had 11 aqueducts — engineered rivers enclosed by masonry — that supplied water to more than a million people in the metropolis, as well as to the city’s many extravagant public baths and fountains. But just how much water was being sourced from distant rivers, lakes and mountain springs has long been a mystery. Now, scientists are putting some impressive numbers to ancient Rome’s water usage based on a study of travertine deposits that built up over time in the Anio Novus aqueduct as freshwater flowed through it to the city.

Northern Cyprus' "Peace Water" Pipeline

With its semi-arid climate and growing population, Cyprus suffers from the highest level of water stress in Europe and is ranked in the top five most water-stressed countries in the world, according to the World Resources Institute. Demand in the larger southern Republic of Cyprus is predicted to increase to 314 million cubic meters per year by 2020, up from 266 million cubic meters in 2004.

Flaring our way out of a water crisis

The production of oil and gas consumes and produces vast amounts of freshwater and wastewater, respectively, and burns tons of natural gas, emitting potent greenhouse gases and wasting a potential energy source. However, with some clever engineering, we could solve all three of these environmental concerns at once.

Declining U.S. water use a challenge for models

Americans are using less water today than they have at any time since 1970, according to a report by the U.S. Geological Survey (USGS), which has tracked water use since 1950 and issues reports every five years.

Geologic Column: Jack and Jill: The sequel

As the extreme drought in California persists into another year, EARTH’s regular commentator returns with some thoughts on the proposed solutions, and the wisdom of going “up the hill” to fetch your water.

Exoplanets could have long-lived oceans

At last count, the Kepler spacecraft had identified more than 1,000 confirmed exoplanets in the Milky Way Galaxy. Some of these bodies orbit their parent stars in the so-called habitable zone, where liquid water, and thus, life, could survive. But scientists say favorable surface temperatures may not be enough to foster life. Exoplanets also need to generate and maintain liquid water at the surface, raising the question: Do exoplanets have stable oceans?

Iraq's biggest dam on unsure footing

Much of Iraq’s national power grid, as well as its irrigation and municipal water supplies, depend on Mosul Dam, a large earthen structure on the Tigris River about 70 kilometers upstream from Mosul, Iraq’s third-largest city. However, the dam, constructed in the 1980s, was built upon a geologically weak foundation, raising worries about its safety.
