Underwater 'tree rings': Calcite crusts of arctic algae record 650 years of sea ice change
Almost 650 years of annual change in sea-ice cover can been seen in the calcite crust growth layers of seafloor algae, says a new study from the University of Toronto Mississauga (UTM).
NASA begins first Antarctic airborne campaign from McMurdo Station
NASA's Operation IceBridge has begun its 2013 Antarctic field campaign with the arrival of the agency's aircraft and scientists at the National Science Foundation's McMurdo Station in Antarctica.
Volcano discovered smoldering under a kilometer of ice in West Antarctica
It wasn't what they were looking for but that only made the discovery all the more exciting.
NASA helps melt secrets of Great Lakes ice
(Phys.org) —Two scientists from NASA and NOAA have developed a new space-based technique for monitoring the ice cover of the Great Lakes that is so accurate it can identify a narrow channel of open water ...
2013 marked by 'record sea level, weather extremes'
Sea levels this year posted a record high, making low-lying coastal populations ever more vulnerable to extreme weather like super-storm Haiyan, the UN said Wednesday.
'Missing heat' discovery prompts new estimate of global warming
An interdisciplinary team of researchers say they have found 'missing heat' in the climate system, casting doubt on suggestions that global warming has slowed or stopped over the past decade.
'Tiger stripes' underneath Antarctic glaciers slow the flow
(Phys.org) —Narrow stripes of dirt and rock beneath massive Antarctic glaciers create friction zones that slow the flow of ice toward the sea, researchers at Princeton University and the British Antarctic ...
A dark and dusty avalanche on Mars
Mars may be geologically inactive but that doesn't mean there's nothing happening there—seasonal changes on the Red Planet can have some very dramatic effects on the landscape, as this recent image from ...
New findings could overcome major stumbling blocks to tissue cryopreservation for medical care
Developing an efficient way to freeze and store living tissues could transform many aspects of medical care and research, but ice crystallization often occurs within cells during such cryopreservation procedures, ...

This photograph by an astronaut on the International Space Station highlights the snout of the Upsala Glacier (49.88°S, 73.3°W) on the Argentine side of the North Patagonian Icefield. Ice flow in this glacier ...
Geoscientists building whole-Earth model for long-term climate clues
A Rice University-based team of geoscientists is going to great lengths—from Earth's core to its atmosphere—to get to the bottom of a long-standing mystery about the planet's climate.
NASA begins airborne campaign to map greenland ice sheet summer melt
For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt.
