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.
Emerging Technologies Help Scientists Tune In to Krill
Acoustic tools identify the population of “the most important fishery in the Southern Ocean.”
Explaining Cold and Fresh Southern Polar Ocean Surface Waters
Global climate models do not reproduce observed trends of the Southern polar ocean surface, but an increase in wind-transported sea ice that melts and inhibits mixing may account for the disparity.
“Terremotos Glaciales” Vistos por Primera Vez en Thwaites
Estos eventos sísmicos, provocados por los icebergs que se vuelcan y chocan contra Thwaites, revelan que el glaciar ha perdido parte de su plataforma flotante de hielo.
A Shared Resource for Studying Extreme Polar Environments
A new community pool of seismic instrumentation will facilitate and advance geologic and cryospheric research in Earth’s ice-covered environments.
The Threat at Thwaites
This Antarctic glacier is rapidly losing mass. An international team is digging into the ice to figure out just how bad it is.
“Glacial Earthquakes” Spotted for the First Time on Thwaites
These seismic events, triggered by icebergs capsizing and ramming into Thwaites, reveal that the glacier has lost some of its floating ice shelf.
