New Insights into Polar Stratospheric Clouds
New satellite observations of polar stratospheric clouds have advanced our understanding of how, when, and where they form, their composition, and their role in ozone depletion.
Brazil’s Antarctic Station Rises from the Ashes
The sophisticated new research station will allow for better science on the icy continent.
South Pole Ice Core Reveals History of Antarctic Sea Ice
Every summer, most of the sea ice near Antarctica melts away, but its saltiness leaves a permanent record that scientists can trace back for millennia.
A Vital Resource Supporting Antarctic Research
The U.S. Antarctic Program Data Center is providing new services to help scientists document, preserve, and disseminate their research and to facilitate reusability of a wide range of valuable data.
Taking the Temperature of Antarctica’s Crust
How do you measure the geothermal heat flux in a continent covered by an ice-sheet? A new study uses correlations of diverse global observables and produces a heat flow map of the entire Antarctica.
Robot Measures Air-Sea Carbon Dioxide Exchange in Southern Ocean
Unique air and ocean surface observations of the Southern Ocean from a 22,000 km, 196-day circumnavigation around Antarctica by an Uncrewed Surface Vehicle.
Antarctic Lava Yields Clues to Earth’s Past Magnetic Field
A new analysis suggests that a widely accepted approximation of ancient magnetic field strength may be less accurate for the past 5 million years than previously thought.
Gravity Data Reveal Unexpected Antarctic Ice Variations
A new analysis of long-term satellite records shows the East Antarctic Ice Sheet is unexpectedly dependent on fluctuations in weather. This study may improve models of how much sea levels will rise.
Antarctica in a Changing Climate
The impacts of the Antarctic Ice Sheet response to climate change will have global consequences for millions living near the coast. It’s just a matter of when.
