Ice Planet Research: More Polar Ocean Turbulence Due To Planetary Warming
A study published in the journal Nature Climate Change by an international team of scientists, from the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea, […]
Ice Planet Research: Antarctic Glacier Retreated Faster Than Any Other In Modern Earth History
A glacier on Antarctica’s Eastern Peninsula experienced the fastest retreat recorded in modern history—in just two months, nearly 50 percent of the glacier disintegrated.
Six-million-year-old Ice Discovered In Antarctica Offers Unprecedented Window Into A Warmer Earth
A team of U.S. scientists has discovered the oldest directly dated ice and air on the planet in the Allan Hills region of East Antarctica.
An Autonomous Robotic Glider Will Circle And Explore Our Ocean Planet
Editor’s note: When we start to mount Astrobiology missions to explore ocean worlds we’ll need ways for our robotic submersibles to observe and interact with whatever life forms they may […]
Ice Planet Research: British Antarctic Survey Discovery Building Comes To Life
The 2025 – 2026 Antarctic season is a landmark for the British Antarctic Survey (BAS) and its Antarctic Infrastructure Modernisation Project (AIMP), as the new Discovery Building begins to take […]
Replacement Found For The Lost Underwater Vehicle Ran
The deal is done for the new underwater vehicle that will replace Ran, the submarine that was lost under a glacier in Antarctica in 2024. A large donation means that […]
Multi-technique Characterization Of Iron Reduction By An Antarctic Shewanella: An Analog System For Putative Martian Biosignature Identification
Microbes from terrestrial extreme environments enable testing of biosignature production in conditions relevant to astrobiological targets.
Planetary Analog Sites In The Indian Subcontinent And The Indian Ocean: Underexplored Environments Suited For Astrobiological And Space Research
The central objective of astrobiology is to evaluate the habitability of other planetary bodies and given the high cost and logistical complexity of space missions, preliminary investigations of planetary analog […]
Waking Up Microbes Trapped In Permafrost For Up To 40,000 Years
In a new study, a team of geologists and biologists led by CU Boulder resurrected ancient microbes that had been trapped in ice—in some cases for around 40,000 years.
