Searching for the perfect road salt
Each winter, Norway spends NOK 1.6 billion keeping its roads fit for use. Researchers have many reasons for wanting to get costs down.
Enormous aquifer discovered under Greenland ice sheet
Buried underneath compacted snow and ice in Greenland lies a large liquid water reservoir that has now been mapped by researchers using data from NASA's Operation IceBridge airborne campaign.
Greenland ice stores liquid water year-round
Researchers at the University of Utah have discovered a new aquifer in the Greenland Ice Sheet that holds liquid water all year long in the otherwise perpetually frozen winter landscape. The aquifer is extensive, ...
Arctic cyclones more common than previously thought
From 2000 to 2010, about 1,900 cyclones churned across the top of the world each year, leaving warm water and air in their wakes—and melting sea ice in the Arctic Ocean.
Study shows increased summer melting not increasing annual movement of Greenland ice sheet
Uncovering the tricks of nature's ice-seeding bacteria
Like the Marvel Comics superhero Iceman, some bacteria have harnessed frozen water as a weapon. Species such as Pseudomonas syringae have special proteins embedded in their outer membranes that help ice crystals form, and th ...
Giant channels discovered beneath Antarctic ice shelf
Scientists have discovered huge ice channels beneath a floating ice shelf in Antarctica. At 250 metres high, the channels are almost as tall as the Eiffel tower and stretch hundreds of kilometres along the ...
Weighing the Antarctic ice sheet
One of the last big unknowns in the global climate equation is Antarctica. How stable is the Antarctic ice sheet? More than a mile thick, on average, it locks up 70 percent of the Earth's fresh water.
Late Cretaceous Period was likely ice-free
For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University ...
Chasing the black holes of the ocean
According to researchers from ETH Zurich and the University of Miami, some of the largest ocean eddies on Earth are mathematically equivalent to the mysterious black holes of space. These eddies are so tightly ...
Catastrophic collapse of ice lake created Aram Chaos on Mars
Aram Chaos, the lumpy, bumpy floor of an ancient impact crater on Mars, formed as a result of catastrophic melting and outflow of a buried ice lake. A new study combines observations from satellite photos ...
Unprecedented rate and scale of ocean acidification found in the Arctic
Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLoS One. The increase in rate is being blamed on rapidly melting sea ice, a proces ...
Mathematician uses skills to study Greenland's retreating glaciers (w/ Video)
Many outlet glaciers in Greenland feed ice from the land into fjords, where discharge of icebergs and melting of the glaciers by warmer ocean waters contribute to rising sea levels.
Near-Earth asteroid is really a comet
Some things are not always what they seem—even in space. For 30 years, scientists believed a large near-Earth object was an asteroid. Now, an international team including Joshua Emery, assistant professor ...
