Photo Friday: The Science Behind Blood Falls’ Unusual Coloring

3 July 2015, by

This Photo Friday, enjoy stunning photos of Blood Falls – an unusual glacial tongue off of Taylor Glacier in East Antarctica. Far from the typical, pristinely white colors of glaciers, Blood Falls sports a trickling red tongue, sometimes invoking its namesake in blood red, other times in a fainter, more subtle burnt orange. Check out the […]

Do Windy Glaciers Melt Faster?

30 June 2015, by

The relationship between surface winds and glacial melt is more complex than previously thought, according to an article in the journal, Boundary-Layer Meteorology, which used new data collecting techniques. The report by Maxime Litt, Jean-Emmanuel Sicart, and Patrick Wagnon, with the Université Grenoble Alpes, France, and, Warren D. Helgason at the University of Saskatchewan, Canada, […]

Roundup: Fish in Patagonia, Film in Kashmir & Glacial Georgia

29 June 2015, by

One Fish, Two Fish: Black Southern Cod maintain a more diverse diet when near glacier meltwater areas “The black southern cod, Patagonotothen tessellata, is the most important notothenioid fish species in terms of abundance in southern Chilean Patagonia. However, studies on its trophic ecology are scarce. [This study assessed] the spatial variation in the diet of […]

Prehistoric Glaciation Influenced Frog Evolution

23 June 2015, by

Extensive studies in continental regions have discovered that climate variations can have strong impacts on the distribution and evolutionary history of species. Now, a study of mountainous areas, where few studies have been conducted, has found similar patterns in the current distribution and population isolation of a frog species on the Tibetan Plateau. The study, […]

Roundup: Snowmaking Guns, Antarctic Ice, and Black Carbon

22 June 2015, by

Ski Resort’s New Snowmaking Guns  Describing a major ski resort in British Columbia, Canada: “De Jong says that after commercial operations end in July, four snowmaking guns and other infrastructure will be installed. It is expected to be used beginning in October. ‘If the pilot project is conclusive, this unique project will become a significant […]

Roundup: the Glacier Run, Models, and Georgia Glaciers

15 June 2015, by

The Glacier Run The 8th Glacier 3000 Run and Gstaad Kids Run will take place on Saturday, August 8, 2015. The racecourse passes through a beautiful alpine landscape offering both runners and spectators many spectacular views. Between the starting point on the Gstaad Promenade at 1’050 meters and the finish line at Glacier 3000 (2’950 […]

Glacial Runoff: Bane or Boon for Aquatic Life?

9 June 2015, by

As glaciers melt around the world, their waters carry high concentrations of sediments into glacial lakes and rivers. That glacial sediment brings some nutrients into the lakes, but also blocks sunlight– the energy source which organisms need to survive. In a recently published paper in The Journal of Plankton Research, titled When glaciers and ice sheets melt: […]

Roundup: Climate Science and International Adaptation

8 June 2015, by

Integration of Glacier and Snow “Energy budget-based distributed modeling of snow and glacier melt runoff is essential in a hydrologic model to accurately describe hydrologic processes in cold regions and high-altitude catchments. We developed herein an integrated modeling system with an energy budget-based multilayer scheme for clean glaciers, a single-layer scheme for debris-covered glaciers, and […]

New Cyanotoxins Surface in Polar Region

3 June 2015, by

Death by cyanobacteria-made microtoxins is not pleasant. The toxins damage the nervous system, especially anatoxin-a, also known as a Very Fast Death Factor. As the global temperature increases, concerns about the range of these toxins are growing. For the first time, anatoxin-a has been found as far north as the polar regions, according to a […]

Glaciers Shape Lives in Upper Hunza

2 June 2015, by

Glacier and river dynamics shaped irrigation systems and land use practices in Pakistan since the late 1700’s, according to a new paper by Sitara Parveen and his colleagues. These systems and practices can still be observed hundreds of years later, but they face severe challenges from glacier retreat. Upper Hunza is located in the western Karakoram, Pakistan. […]

Roundup: Bubbling Ice, Black Carbon, and Glacial Advance

1 June 2015, by

The sound of glaciers A new article in the scientific journal Geophysical Research Letters, titled Unusually loud ambient noise in tidewater glacier fjords: A signal of ice melt, tracks glacial melt by recording the sounds of the glaciers bubbling underwater in glacial bays. Check out videos of the unique sounds below, and read the article here.   […]

Photo Friday: Cryoconites and Glacier Tables

29 May 2015, by

Have you ever seen dark cavities on glaciers, which are also referred to as “cryoconites”? These holes, which can be meters deep,are created from debris on top of glaciers. Dark-colored debris, including soot, dust, and pollen, speed up the melting process of glacial ice as a consequence of their low reflectivity to incoming sunlight. In […]
