Wind, sea ice changes suggest climate change in western Arctic

A major shift in western Arctic wind patterns occurred throughout the winter of 2017 and the resulting changes in sea ice movement are possible indicators of a changing climate, according to authors of a new study.

New study helps explain Greenland glaciers’ varied vulnerability to melting

Using data from NASA missions observing Earth, researchers at the University of California, Irvine have created new maps of the bed topography beneath a score of glaciers in southeast Greenland, thereby gaining a much better understanding of why some are undergoing rapid retreat and others are relatively stable.

How much snow accumulates in North America each year? More than scientists thought

There’s a lot more snow piling up in the mountains of North America than anyone knew, according to a first-of-its-kind study. Scientists have revised an estimate of snow volume for the entire continent, and they’ve discovered that snow accumulation in a typical year is 50 percent higher than previously thought.

Ice-age echoes affect present-day sea level

A new study has, for the first time, cut a clear path through a nettlesome problem: accurately measuring a powerful effect on global sea level that lingers from the last ice age. Just how quickly Earth’s deep, rocky mantle is rebounding from the heavy burden of ancient ice sheets and oceans remains somewhat uncertain. But this rebound effect, known as glacial isostatic adjustment (GIA), is critical to properly understanding the causes of sea level change.

New study reveals how icy surface ponds on Himalayan glaciers influence water flow

The flow of water that supports hydro-electric and irrigation infrastructure in the mountain regions of Nepal and India is regulated by hundreds of large icy ponds on the surface of some of the world’s highest glaciers, scientists have revealed.

Glacial moulin formation triggered by rapid lake drainage

Scientists are uncovering the mystery of how, where and when important glacial features called moulins form on the Greenland Ice Sheet. Moulins, vertical conduits that penetrate through the half-mile-deep ice, efficiently funnel the majority of summer meltwater from the ice surface to the base of the ice sheet.

New Antarctic heat map reveals sub-ice hotspots

An international team of scientists, led by British Antarctic Survey (BAS), has produced a new map showing how much heat from the Earth’s interior is reaching the base of the Antarctic Ice Sheet.

Secrets of hidden ice canyons revealed

In a new study, scientists have discovered huge canyons cutting through the underbelly of Antarctica’s ice shelves, meaning they may be more fragile than previously thought. Thanks to the CryoSat and Sentinel-1 missions, new light is being shed on this hidden world.

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.

Researchers take on atmospheric effects of Arctic snowmelt

Researchers at the University of Alaska Fairbanks’ Geophysical Institute are exploring the changing chemistry of the Arctic’s atmosphere to help answer the question of what happens as snow and ice begin to melt. The research is concerned with the Arctic’s reactive bromine season, the period of time when bromine is consuming ozone, producing bromine monoxide and oxidizing mercury.
