Who’s Evaluating Swiss Landscapes?

If beauty is in the eye of the beholder, how do you define a beautiful landscape? Machine learning algorithms can be helpful here, says Adrienne Grêt-​Regamey.

Tackling “the Ultimate Challenge” in Greater Depth

I am delighted to join the MRI as a Scientific Project Officer and, as part of the GEO-GNOME project, look forward to working in an interdisciplinary and collaborative fashion to improve the availability and accessibility of data pertaining to the earth’s mountainous regions. Below, by way of self-introduction, I take the opportunity to say a few words regarding my recent doctoral research.

Opinion: If we want to increase trust in science, we need to direct more research dollars to rural America

Pandemic relief funding should provide a much-needed boost to scientific research. And we should steer those dollars toward where they can do the most good.

Ambassador of Interdisciplinary Mountain Research | Interview with Connie Millar

Connie Millar in the East Humboldt Range, Nevada

During the 2019 Annual Meeting of the American Geophysical Union (AGU) in San Francisco, California, Dr. Constance Millar, USDA Forest Service Pacific, Southwest Research Station, Albany, California, was honoured with an AGU Ambassador Award. The award was given for her outstanding contributions and inspiring interdisciplinary research and leadership on how mountain flora and fauna adapt to climate change, and for building a diverse scientific community to guide management of these natural resources.

Does debris cover offset glacier retreat in the Greater Caucasus?

Elbrus Mountains

In this blog post, Levan Tielidze tells us about supra-glacial debris cover change for the Greater Caucasus. His recent study indicates more than a doubling in the area of supra-glacial debris cover for the Elbrus Massif‘s glaciers from 1986 to 2014, the largest glacierized massif in the whole region.

COVID-19 in Glacier Regions Update: Latin America Responds, Italy Uses Drones to Enforce Quarantine, and the US Copes

A village below the Peruvian Cordillera Blanca

 

For the past two weeks GlacierHub has made space in the usual Monday news roundup for coverage of the coronavirus pandemic as it impacts glacier regions. In continuing that reporting, the following is an aggregation of coronavirus news stories from global glacier regions, written by guest author Peter Deneen.

Acodado Glacier, Chile Retreat Yields Tripling in Lake Area 1987 - 2020

Loriaux and Casassa (2013)  examined the expansion of lakes of the Northern Patagonia Ice Cap (NPI). From 1945 to 2011 lake area expanded 65%, 66 km 2 . Rio Acodado has two large glacier termini at its headwater, HPN2 and HPN3. that are fed by the same accumulation zone and comprise the Acodado Glacier. The glacier separates from Steffen Glacier at 900 m. The lakes at the terminus of each were first observed in 1976 and had an area of 2.4 and 5.0 km 2  in 2011  (Loriaux and Casassa, 2013).    Willis et al (2012)  noted a 3.5 m thinning per year from 2001-2011 in the ablation zone of the Acodado Glacier, they also note annual velocity is less than 300 m/year in the ablation zone.  Davies and Glasser (2012)  noted that the Acodado Glacier termini, HPN2 and HPN3, had retreated at a steadily increasing rate from 1870 to 2011....

A Reservoir of Difficulties for Hydropower

Grande Dixence Dam

Hydropower will have to undergo big changes if it’s to meet the demands of the Energy Strategy 2050. But this old source of renewable energy is faced with problems today. We look at the recommendations made by the National Research Programme.

Here’s How Some of Earth’s Most Breathtaking Landscapes Are Created by Glaciers

Glaciers have carved some of Earth’s most beautiful landscapes by steepening and deepening valleys through erosion. Think of the Scottish Highlands, Yosemite National Park in the US, or the Norwegian Fjords. But big questions remain about how glacial erosion works.

A problem for scientists seeking to understand how glaciers affect the landscape is that the processes of glacial erosion are very complex and not fully understood. For the most part that’s because these processes occur under tens, hundreds or even thousands of metres of ice – we simply can’t observe them.

Risks and Options from New Lakes in the Andes of Peru: Implications for Future Water Management

In the Andes of Peru and adjacent arid lowlands, human subsistence often depends on year-round streamflow from glaciers and lakes, particularly in the dry season. However, global change impacts increasingly affect local hydrology and associated livelihoods which is clearly demonstrated by the impacts of glacier shrinkage. Rapidly growing lakes (Fig. 1) in deglaciating mountain regions potentially imply severe risks but also options for human livelihoods.
