The First Wave of the "Thwaites Invasion"
The U.S. and U.K.-funded International Thwaites Glacier Collaboration (ITGC) officially kicked off its science field research in January, when four researchers and their support teams set foot on a remote, fast-melting glacier in West Antarctica, establishing a beachhead for an unprecedented international project to determine the glacier's fate.

An Ecosystem Grows in Antarctica
Antarctica's native microorganisms are a hearty bunch, able to eke out a living on the planet's coldest, highest, driest, windiest and emptiest continent. But the region wasn't always quite as hospitable as it is today.

Buried Treasure
A team of researchers has brought home samples of some of the oldest ice ever discovered, more than twice as old as most previous samples. In the remote Ong Valley, the team drilled into a bed of ice - that first fell as snow two million years ago, or more.

IceBridge Flies High
In late 2017, a specially modified airplane contracted by NASA crisscrossed Antarctica, mapping the ice below and filling in a data gap left by a now-defunct NASA satellite called ICESat, which measured the elevation of the ice surface using a laser. Operation IceBridge flights are bridging the gap between ICESat and its successor, ICESat-2.

A Chemical Detective Story: Why is Don Juan Pond So Salty?
During winter, nearly everything in Antarctica freezes solid. Except Don Juan Pond. Though only about twice the area of an Olympic-sized swimming pool, and barely a foot deep, Don Juan Pond is famous for being the saltiest body of water on the entire planet. It is saltier even than the Dead Sea.

A World-Class Classroom At The Bottom Of The World
For early-career scientists, learning the ropes in Antarctica can mean donning actual safety lines and harnesses. This past austral summer, 20 students traveled to the National Science Foundation's McMurdo Station to conduct a range of experiments and learn first-hand what it's like to do research at the bottom of the world.

Ultraviolet Radiation Gives Microbes Mixed Messages
Ultraviolet rays from the sun may be disrupting the natural ecology of the waters of Antarctica's Southern Ocean. A research team, led by a scientist from the Woods Hole Oceanographic Institute, is taking a close look at the effects that excess UV radiation at the cellular level to see what it means for marine ecosystems and the regional food web.
