Glacial Moraines Influence New Techniques in Micro Biomedicine

10 March 2015, by

A recent piece of biomedical research has drawn extensively from an unexpected source, glacial moraines. Moraines form as glaciers advance across landscapes over hundreds or even thousands of years, pushing rocks and boulders along their way. If you can imagine the pile of snow that accumulates in front of a sled as it rushes down towards the […]

Roundup: Calving, ‘Record grooves’ and Story Maps

9 March 2015, by

Calved Greenland Iceberg  “Iceberg calving is ultimately related to the mechanical failure of ice. However, predicting mass loss from calving events remains challenging because calving takes on diferent forms under different conditions. For example, large tabular icebergs sporadically detach from freely foating ice tongues with many years of quiescence between major calving events” Read more […]

Eruption in Glacier-covered Volcano in Chile

6 March 2015, by

One of South America’s most active volcanoes, Villarrica, erupted Tuesday, 3 March 2015,  around 3 a.m. local time in Chile, creating a danger that lava would interact with the large ice cap on the mountain. The volcano spewed a lava fountain 1.5 kilometers into the air, and the pillar of smoke and ash reached 6-8 […]

Photo Friday: Iceland’s Black Sand Beaches

6 March 2015, by

When a volcano erupts from underneath a glacier, pulses of meltwater deposit materials in outwash plains. The 1918 subglacial Katla volcano eruption in southern Iceland formed the Mýrdalssandur glacial outwash plain. This plain, which covers hundreds of square kilometers, includes a number of striking  black sand beaches, including a particularly well-known one in the town of Vík í Mýrdal. Here is […]

Mapping South Asia’s Glaciers

5 March 2015, by

Recent research has provided valuable information on glacier processes in the Hindu Kush Himalaya (HKH) mountains of South Asia, a region often called the “Third Pole” because it contains the largest area of ice outside the Arctic and Antarctic. Glacier retreat in this region has attracted considerable scientific and media attention. The 2007 Fourth Assessment Report of the Intergovernmental Panel […]

Girls Breaking Ground on Ice

4 March 2015, by

As a student, I had no idea that I ever wanted to study anything related to science- much less the “hard” sciences. Often, I was pointed in the direction of social science because of my writing ability and creativity. Although my high school days weren’t long ago, this experience is common among young women due […]

Freed of Ice, Iceland Rises

3 March 2015, by

Iceland is, in fact, a land of ice. It is home to at least 269 glaciers, which occupy the equivalent of over 1.4 billion Olympic swimming pools. But those glaciers are melting, causing the land underneath to rise as the weight of the ice lifts. According to a new study published online in Geophysical Research Letters […]

Roundup: Nepal Symposium, Microrefugia, Climate Change

2 March 2015, by

Symposium on Glaciology in High-Mountain Asia (1 – 6 March, 2015) “The high mountains of Asia are estimated to contain one of the greatest concentrations of glacier ice outside the polar regions, and are the headwaters of rivers which support agriculture and livelihoods of over one billion people. Changes in snow, ice, and permafrost due […]

Photo Friday: Mount Aragats

27 February 2015, by

Mount Aragats, a 13,435 ft mountain peak in northwestern Armenia, is located to the northwest of Armenia’s capital city of Yerevan and north of the Ararat Plain. There is no doubt that it is the highest mountain in Armenia, which places it on the World Country High Points peak list. Aragats is a large circular andesitic-to-dacitic stratovolcano that […]

Mining a Norwegian Glacier for Luxury Ice Cubes

26 February 2015, by

The World’s Most Wanted Ice Cube: that’s the tagline a Norwegian company is using to market ice cubes carved out of a melting ten-thousand-year-old Norwegian glacier. It plans to sell them to owners of upscale bars in Dubai, London and New York. After all, if you are sipping a $50 7-star cocktail served in a glass […]

Glaciers Influence Marine Invertebrates in Chile

25 February 2015, by

Zooplankton are tiny creatures that drift in water bodies. A recent study by Meerhoff et al. in Progress in Oceanography describes linkages which connect them with glaciers. The researchers observed meroplankton—organisms which have planktonic features in their larval stages, but live sessile in the bottom as adults. They worked in the fjords of the Baker […]

Four Centuries of Glacier Art

24 February 2015, by

  Now on view at the McMichael Canadian Art Collection in Kleinburg, Ontario, the exhibition “Vanishing Ice: Alpine and Polar Landscapes in Art, 1775-2012” explores the aesthetic and cultural significance of glaciers for Western art over the past 400 years. The exhibit aims to inspire audiences to take action to protect the world’s glaciers as […]
