Roundup: Measuring Ice, Alpine Lakes’s Biota, Risky Glacier Trek, IceBridge

17 November 2014, by

How much ice is left underneath Alaska’s glaciers “Scientists are trekking across Ruth Glacier in Denali National Park in Alaska, dragging a sled with ground-penetrating radar equipment over the ice. Their mission: reconstruct this glacier’s history and find out how much time these icy giants have left. “So what we’re interested in doing is looking […]

Roundup: Pollutants, Columbia Glacier Retreat, Cryo Consortium

10 November 2014, by

Pollutants from Glaciers “As glaciers increasingly melt in the wake of climate change, it is not only the landscape that is affected. Thawing glaciers also release many industrial pollutants stored in the ice into the environment. Now, within the scope of a Swiss National Science Foundation project, researchers from the Paul Scherrer Institute (PSI), Empa, […]

Dark Snow Spells Doom for Glacial Melt Rates

6 November 2014, by

“One week-old snow was turning black and brown before my eyes,” American geologist Ulyana Horodyskyj told the Guardian in earlier this year as she stood at her mini weather station, 5,800 meters above sea level on Mount Himlung, on the Nepal-Tibet border. Horodyskyj studies glaciers in Nepal’s Himalaya mountain range and is one of the many scientists, bloggers, […]

As Glaciers Melt, They Hum Too

4 November 2014, by

The hills are alive with the sound of… humming? Scientists from the U.S., France and Switzerland recently found that as glaciers melt, they make a low humming sound as water passes through them, according to a new study appearing last month in the journal Geology. The phenomenon was first observed in the Swiss Alps when […]

Yes, Glaciers Melt, But Do You Know How?

30 October 2014, by

Have you ever wondered how glaciers melt? Do they melt from underneath? Top down? Maybe from all around at once? From the center outward? How fast do they melt? Do all glaciers melt? These are questions scientists’ wonder too, and they’ve been getting some interesting answers. Virtually every glacier on earth melts each year during […]

Icelandic Zombie Glacier Survives by Shedding Dead Bits

28 October 2014, by

It’s alive! British scientists recently discovered that a glacier named Falljökull in Iceland, considered dead, is in fact partially “alive.” Using 3D imaging of the interior and surface of the glacier, they found that its long top section, which extends in a steep ice fall from the ice cap Öraefajökull to a plateau below, has at least temporarily saved itself by […]

Glaciers + Algal Blooms = Good?

23 October 2014, by

The pros and cons of algal blooms, high concentrations of phytoplankton in the oceans, are a subject of much debate. But several studies in recent months have examined links between changing polar environments, exponential growth of algal blooms, and potential for carbon reduction. One study, appearing in the journal Nature Communications in May 2014, suggests […]

As Glaciers Melt, A Lake in Nepal Fills Up

22 October 2014, by

  Glaciers on Nepal’s Imja Tse (Island Peak) in the Himalayas have melted at an average rate of almost 10 meters per year over the past several decades, during which time residents of Imja Tse Valley below have literally watched the residual waters create an entirely new lake. The Imja Tsho (Imja Lake) first began […]

Roundup: Mars Glaciers, Tourism Up and Body Found

20 October 2014, by

Second Body found on Siachen Glacier in Two Months “It has been 18 years since Gaya Prasad, a Sepoy in the Indian Army, was proclaimed dead in December 1996. His team was trapped in a minor avalanche on the Siachin Glacier and he was declared dead after prolonged searches couldn’t help in tracing him.” Read […]

Hundreds of Millions of South Asians At Risk from Glacier Melt

16 October 2014, by

Few regions on Earth depend as heavily on glaciers for food, energy and water as South Asia’s Hindu Kush Himalayan ecosystem. A new research paper in the journal Environmental Science and Policy highlights some of the challenges downstream communities face when glacier water from upstream communities becomes scarce. The greater South Asian region accounts for […]

Roundup: Glacier Names, Pakistani Disasters and More

13 October 2014, by

Iceland names 130 new glaciers “The new names mainly refer to places in the vicinity. For example, Kerlingarbaksjökull lies to the west of the mountain Kerling in Eyjafjörður, Sýlingarjökull in Svarfaðardalur is named after the mountain Auðnasýling and Dyrajökull lies in the Dyrfjöll mountains in Borgarfjörður eystri, as stated on ruv.is. Oddur is working with local […]

Glaciers Recede in East Africa’s “Mountains of the Moon”

9 October 2014, by

The Rwenzori Mountains of equatorial East Africa are widely known to be the legendary “Mountains of the Moon” described by Ptolemy in 150 A.D. as ‘the Mountains of Moon whose snows feed the lakes, sources of the Nile’. Indeed, snow and ice on these glaciated mountains that straddle the border between the Democratic Republic of Congo […]
