Study suggests heavy rains from tropical cyclones distort the ground below
Earth’s surface is constantly shifting, expanding and compressing in response to atmospheric and hydrologic forces from aboveground. A new study finds that compression of Earth’s crust is correlated with heavy rainfall from hurricanes and typhoons, known collectively as tropical cyclones. The added weight of all that water likely causes the ground underneath the storm to deform, according to the study’s authors.

Scientists sift through lunar dirt for record of early Earth’s rocks
A team of scientists are examining crushed rocks brought back from the moon by Apollo astronauts for evidence of minerals that might have been formed in the presence of water to better understand the early formation of Earth. They presented the preliminary results of their work last month at the 2017 American Geophysical Union Fall Meeting in New Orleans.

Scientists help Costa Rican community manage dwindling water supply
As part of an interdisciplinary, international research team called FurturAgua, researchers from the University of British Columbia and Simon Fraser University have developed a tool they call the Groundwater Recharge Indicator for two watersheds in the Guanacaste Province of Costa Rica. The Groundwater Recharge Indicator can help community leaders prepare for the dry season by providing an estimate of water availability based on rainfall during the wet season. With this new tool, authorities can implement water conservation efforts such as collecting rainwater or using surface water instead of groundwater before the dry season begins and potential droughts occur, according to the researchers.

Researchers develop model that could reduce wave-induced injuries to Delaware beachgoers
Being pummeled by a large wave can quickly ruin a perfect beach day, as it may require a trip to the hospital or even worse. But researchers in Delaware have developed a new method that could predict when wave-induced injuries are most likely to occur, potentially reducing incidences of these injuries to unsuspecting beachgoers along the state’s coast, according to scientists who presented the research last month at the 2017 American Geophysical Union Fall Meeting in New Orleans.
