Does Debris Cover Offset Glacier Retreat In The Greater Caucasus?

21 April 2020, by

An analysis of debris-covered glaciers in the Caucasus found an increase of supra-glacial debris on all of the nearly 700 glaciers examined. Those with debris melted slower, suggesting debris may partially offset glacier mass loss.

Photo Friday: Outlet Glaciers of Greenland

17 April 2020, by

Each August a team of earth scientists and polar engineers make a routine maintenance trip to Greenland to keep a network of sensors functioning in one of the planet’s most inhospitable climates. They took photos along the way, we shared them.

Acoustics of Meltwater Drainage in Greenland Glacial Soundscapes

16 April 2020, by

Environmental soundscapes provide information across a varied range of phenomena, but glaciers represent a relatively new soundscape frontier. A new paper presents the first evidence of unexplained acoustic phenomena being generated by water drainage through a crevasse on Bowdoin Glacier in Greenland.

Robotic Kayaks Discover High Rates of Underwater Glacier Melt

14 April 2020, by

A recent study using autonomous kayaks found evidence that ambient submarine melting beneath the tongue of Alaska’s LeConte Glacier has been underestimated by a factor of up to 100. The finding opens the door for further research into a previously minimized factor in glacier melt.

Celebrating Women in the Cryosphere

26 March 2020, by

To celebrate Women’s History Month, we selected five of our favorite stories about women in the cryosphere: a Japanese woman who was the first woman to summit Mount Everest, a Qashqai activist who lost her life when Iran downed a Ukrainian Airliner earlier this year, an all-female Andean climbing team, a glacier-based educational program for young women, and AGU President and polar scientist Robin Bell.

Roundup: COVID-19 Glacier Regions Update, Some US National Parks Close, Mines in the Peruvian Andes, and 2020 Research Put On Ice

23 March 2020, by

In this week’s Roundup we updated coverage of glacier regions affected by COVID-19, noted the mutually opposed status of US national parks, highlighted the closure of mines in the Peruvian Andes, and reported on the impact to 2020 cryosphere field research.

Glacier Retreat Drives 400% Lake Expansion Southern Alps, New Zealand 1990-2020

19 March 2020, by

Glaciers of New Zealand’s Southern Alps have been losing ice volume since 1978, with an increasing rate in the last decade, resulting in a 400% expansion in the size of the glacial lakes fed by their meltwater.
