Researchers discover surprising waves in the Antarctic atmosphere

Researchers who have spent thousands of hours observing the atmosphere high above Antarctica have discovered a previously unknown class of wave that ripples constantly through the atmosphere, likely affecting high-level winds, climate, and even Earth-based communications systems.

Study finds high melt rates on Antarctica's most stable ice shelf

A new study measured a melting rate that is 25 times higher than expected on one part of the Ross Ice Shelf. The study suggests that high, localized melt rates such as this one on Antarctica's largest and most stable ice shelf are normal and keep Antarctica's ice sheets in balance.

Data management isn't optional; it's essential to being successful

John Bates is Principal Scientist for Remote Sensing at the National Centers for Environmental Information of the U.S. National Oceanic and Atmospheric Administration/National Environmental Satellite Data and Information Service (NOAA/NESDIS). Here Bates reflects on his experience with data management and how he became an advocate for Earth and space science data management activities.

Drones in a cold climate

As climate change reshapes the Earth's polar regions, scientists turn to drone-mounted cameras to measure sea ice. One expedition found out that flying drones near Antarctica isn't easy.
