Rapid decline of Arctic sea ice a combination of climate change...

Arctic sea ice in recent decades has declined even faster than predicted by most models of climate change. Many scientists have suspected that the...

When the Arctic coast retreats, life in the shallow water areas...

The thawing and erosion of Arctic permafrost coasts has dramatically increased in the past years and the sea is now consuming more than 20...

New study shows when Pine Island Glacier retreat began

Reporting this week (Wednesday Nov. 23) in the journal Nature an international team led by British Antarctic Survey (BAS) explains that present-day thinning and...

Lazarus ice

Every school child knows that ice melts in the summer and freezes in the winter. But it turns out that the process isn't that...

Insights into biogeochemical cycles based on glacial meltwater chemistry

Ph.D. student Lukasz Stachnik received funding from the Arctic Field Grant (AFG) in 2012 and 2013. He has, together with colleagues from HiSF and...

Tides stir up deep Atlantic Heat in the Arctic Ocean

Researchers have identified how warm Atlantic water that is flowing deep into the Arctic Ocean is mixing with colder waters above to contribute to...

Arctic gives clues on worst mass extinction of life

Extreme global warming 252 million years ago caused a severe mass extinction of life on Earth. It took life up to 9 million years...

New technique settles old debate on highest peaks in US Arctic

Finding out which is the highest mountain in the US Arctic may be the last thing on your mind, unless you are an explorer...

Cosmopolitan snow algae accelerate melting of Arctic glaciers

The role of red pigmented snow algae in melting Arctic glaciers has been strongly underestimated, suggests a study to be published in Nature Communications...

Permafrost thawing below shallow Arctic lakes

New research shows permafrost below shallow Arctic lakes is thawing as a result of changing winter climate. Warmer winters combined with an increase in snowfall...

Studies how Arctic soils are affected by precipitation, mainly snow

Neil Sturchio, professor and chair of the University of Delaware's Department of Geological Sciences, is exploring how the thawing of permafrost, a subsurface layer...

Clams help date duration of ancient methane seeps in the Arctic

Clams, mussels, scallops and oysters sound like delicious items on a restaurant menu. But bivalves such as these are much more than that: They...

Reconstruction of Arctic climate conditions in the Cretaceous period

Scientists at the Goethe University Frankfurt and at the Senckenberg Biodiversity and Climate Research Centre working together with their Canadian counterparts, have reconstructed the...

UTSA geoscientists prepare for October trip to the Arctic

In October, UTSA College of Sciences faculty members Stephen Ackley and Blake Weissling wlll travel to the Arctic as a part of a project...

New source of methane discovered in the Arctic Ocean

Methane, a highly effective greenhouse gas, is usually produced by decomposition of organic material, a complex process involving bacteria and microbes. But there is another...

New research identifies diverse sources of methane in shallow Arctic lakes

New research into the changing ecology of thousands of shallow lakes on the North Slope of Alaska suggests that in scenarios of increasing global...

New source of methane for gas hydrates in Arctic discovered

Research led by a University of New Hampshire professor has identified a new source of methane for gas hydrates -- ice-like substances found in...

Friction means Antarctic glaciers more sensitive to climate change than we...

One of the biggest unknowns in understanding the effects of climate change today is the melting rate of glacial ice in Antarctica. Scientists agree...

Methane seepage from Arctic seabed occurring for millions of years

Natural seepage of methane offshore the Arctic archipelago Svalbard has been occurring periodically for at least 2,7 million years. Major events of methane emissions...

New discovery in Arctic is a very old clam
