Water

As the Colorado River carved the Grand Canyon, it flushed away ancient groundwater. The discovery was made using a new method that determines the age of water based on how much of the radioactive element krypton-81 is present.

For the seventh year in a row, UArizona hurricane forecasters predict an above-average hurricane season, beginning June 1. Their forecast shows 14 named storms and seven hurricanes developing over the Atlantic Ocean.

Irina Panyushkina grew up in Siberia, hearing stories of explorers trudging through seas of ice to reach the North Pole. She is now a climate scientist trying to understand how a warming world is transforming the place she called home.

Most scientists researching California's extreme weather have focused their investigations on the last decade. But new UArizona research finds that an increasing trend in extreme weather began half a century ago.

Surprisingly little is known about how rain moves through landscapes once it's on the ground. A $3.5 million grant will allow scientists to study the role of plants and microbes in the process.

Hurricanes and tropical storms are slowing down and dumping more water in the process. At-risk communities could use new research findings to prepare for future disasters.

HydroGEN, a UArizona-led project funded by the National Science Foundation's Convergence Accelerator program, will allow researchers to build a national platform for hydrologic forecasting.

Beneath Earth's surface is a vibrant world of life unlike any other, and researchers hope to dig into its secrets by partnering with companies that drill up to thousands of feet deep.

New research suggests that the volume of salty water 2 to 10 kilometers (6.2 miles) beneath the Earth's surface is double previous estimates. The water could store waste fluids, sequester carbon and direct our search for extraterrestrial life.
