Down to Earth With: Hydrogeologist Shemin Ge

When Shemin Ge graduated from high school in China, the country was still in the throes of the Cultural Revolution. During this movement, which lasted from 1966 to 1976, many colleges and universities were closed, and Ge, like most teenagers from urban areas, was sent to work in the countryside. She was assigned to a brick-making factory, where she had to haul heavy, machine-molded bricks outside so they would dry in the sun. Unless the forecast called for good weather, the teens also had to cover the bricks each evening to prevent them from cracking in the rain.

A new study has quantified damage done by the resulting storm surge to the fragile coastal aquifers that residents of one town rely on, and how long it might take for the aquifers to recover.

Hydrological models locate ancient human migration routes

Archaeologists and geologists have long hypothesized that major river systems flowed north through the Sahara Desert about 100,000 years ago. These rivers would have provided a sort of network of “green corridors” across the Sahara that early humans could have traversed as they migrated out of Africa. Ancient lake records, fossil river systems, and radioisotope data have offered evidence for the existence of flowing water in the region.

Clearing roadways: A little salt goes a long way

Although winter in the Northern Hemisphere does not technically begin for another month, snowfalls and icy conditions are already making driving hazardous. When winter weather strikes, most states spread salt to clear roadways. However, more and more studies are showing that salt has lasting environmental repercussions, which may force a winter roadway maintenance overhaul. But if not salt, then what?
