Everest’s Glaciers in Peril

27 May 2015, by

Even the highest glaciers in the world will not escape the effects of climate change, according to a study published today (27 May) in  The Cryosphere, an open access journal of the European Geosciences Union (EGU). This study shows that the glaciers in the Everest region are very sensitive to warming, and will shrink massively […]

Glacial Retreat Encourages Seaweed Colonization

26 May 2015, by

Newly ice-free areas exposed by glacial retreat in Potter Cove, Antarctica, are being colonized by seaweed. With glaciers melting, the original white, mostly lifeless Antarctica is now becoming darker and lively with seaweed. These macroalgae not only produce oxygen for marine species through photosynthesis but also serve as the base of the marine food chain. […]

Roundup: Cyanobacteria, Glacier Calving and Glacier Fluctuations

25 May 2015, by

Arctic biocrust cyanobacterial communities “In the polar regions cyanobacteria are an important element of plant communities and represent the dominant group of primary producers. They commonly form thick highly diverse biological soil crusts that provide microhabitats for other organisms. Cyanobacteria are also producers of toxic secondary metabolites. The north-west coast of Spitsbergen, are able to […]

Supercool water found near glaciers

20 May 2015, by

Temperatures in Spitbergen, Norway may be below freezing, but the water around the Glacier Front isn’t frozen, researchers Eugene Morozov from Shirshov Institute of Oceanology, Aleksey Marchenko from the University Center in Svalbard, and Yu. D. Fomin from Moscow Institute of Physics and Technology, found, This process of supercooling, also known as undercooling, happens when the temperature of […]

The Sound of Glacial Calving

19 May 2015, by

Listening to the unique creaks and cracks of an arctic fjord, six researchers affiliated with the Polish Academy of Sciences recorded the sounds glaciers make as they break off into water. The recordings are being used in an important effort to better understand this process of breaking off, called calving. Glacial calving is “poorly understood” […]

Roundup: Irrigation, Monitoring, and Tidewater

18 May 2015, by

Evolution of Socio-hydrological Interactions in the Karakoram  “Based on three case studies, this paper describes and analyzes the structure and dynamics of irrigation systems in Upper Hunza, located in the western Karakoram, Pakistan. In these deeply incised and arid valleys, glacier and snow melt-water are the primary water sources for agricultural production. The study shows […]

Melting Glaciers, Changing Careers

13 May 2015, by

Climate change is making the work of glaciologists complicated. Scientists that study paleoclimatology of the Earth have come to the realization that melting ice and receding glaciers are getting in the way of their fieldwork. “Time no longer starts at the surface,” said Lonnie Thompson, a paleoclimatologist at the Byrd Polar Research Center at the […]

Roundup: Western Canada, Supercooled Water and Seaweed

11 May 2015, by

Glacier Change: Dynamic Projections “Mountain glaciers around the world are in decay. According to a modelling study that — unusually — includes full ice flow physics, those in Western Canada will largely be restricted to the coastal region by the year 2100.” See more about this article here.   Supercooled Water near the Glacier Front  […]

Photo Friday: Visible Glacier Shrinking in Puncak Jaya

8 May 2015, by

Even though mountain peaks near the equator have supported glaciers for thousands of years, they have retreated significantly in the last century because of climate change. Many tropical glaciers have lost more than half of their volume with the rapid development of global industry. Puncak Jaya, the earth’s highest island peak in Indonesia, holds the […]

Adaptation to Drought in Peruvian Andes

6 May 2015, by

Community-based adaptation strategies are essential for dealing with drought in the Peruvian Andes, according to a new study by Ralph Lasage et al. published in Sustainability. Over 80% of residents in the Peruvian Andes rely on agriculture as a major source of income and are highly dependent on the availability of water resources. But in […]

Glacier Retreat Threatens Insect with Extinction

5 May 2015, by

As glaciers retreat, a species of glacier-dependent stonefly faces extinction. In 2010, the Center for Biological Diversity petitioned for Zapada glacier, a western glacier stonefly only found in alpine streams of Glacier National Park, Montana, to be listed as endangered species under the U.S. Endangered Species Act. This species – one of more than 3500 […]

Photo Friday: Glacier Crevasses

1 May 2015, by

When glaciers retreat under rocky terrain, they form cracks which vary in width, depth and length. These cracks are called crevasses. A person who encounters a crevasse may appreciate nature’s beauty and form, or find the crevasse very frightening. Glacier climbers often explore crevasses along their way and scientists descend down a crevasse to study […]
