Can Arctic ‘ice management’ combat climate change?

Both sea ice retreat and global warming could be slowed by millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter. Researchers have now, for the first time, tested the concept using a complex climate model.

Postcards from a frozen icebreaker – Part 12

Below -30C for the first time at MOSAiC. The helicopter dropped us off. Dave, Hans, and I at the L1 site, some 15 km away from Polarstern. A flurry of activity as we unload our gear from the helicopter and pull it out of the downwash…. Then up and away, … and …. Silence. Darkness. This is really it: the Arctic winter.

Postcards from a frozen icebreaker – Part 11

Working in the Arctic can, of course, be a huge challenge. The fingers, toes and nose bearing the brunt of it. Delicate instrument work is particularly hard as this often requires taking off warm outer gloves to expose hands with thin or no gloves. But in the end, it is rarely the actual temperature that matters. Instead the wind is the key factor.

Postcards from a frozen icebreaker – Part 10

Time is such an odd concept out here. The sun is long gone; now we have at most only a sliver of lighter skies on the far horizon framing extensive darkness in all directions. No real reference for daily time….. the food schedule onboard providing the only framework.

Postcards from a frozen icebreaker – Part 9

The ice has been trucking along quickly to the north, and with the recent drift we have finally moved north of our original installation position and are now on our way towards the North Pole.

Uncovering polynya: new research unravels 43-year-old Antarctic mystery

Researchers at NYU Abu Dhabi have discovered how the Maud-Rise Polynya that was initially spotted in Antarctica in 1974, reappeared in September 2017 at the same location.

Arctic change has widespread impacts

As the Arctic warms faster than the rest of the globe, permafrost, land ice and sea ice are disappearing at unprecedented rates. And these changes not only affect the infrastructure, economies and cultures of the Arctic, they have significant impacts elsewhere as well.

Tracking driftwood gives researchers insight into past Arctic Ocean changes

Wood from trees that fell into Arctic-draining rivers thousands of years ago is giving scientists a detailed look at how Arctic Ocean circulation has changed over the past 12,000 years. In a new study, researchers used nearly 1,000 pieces of driftwood collected from Arctic shorelines since the 1950s to track Arctic sea ice extent and ocean circulation since the start of the Holocene.

Arctic sea ice loss likely not a factor in recent Northern Hemisphere cold winters, study finds

Arctic sea ice loss is a major factor behind the warming Arctic, but melting sea ice is probably not behind recent cold winters in parts of Europe, Asia, and the United States, according to new research. Recent accelerated warming of the Arctic has coincided with several unusually cold winters in the Northern Hemisphere’s mid-latitude continents. This winter temperature pattern has been referred to as “Warm Arctic, Cold Continents,” and some scientists have proposed that Arctic change is the driver.
