“A glaciologist once wrote that the number of glaciers in Alaska “is estimated at (greater than) 100,000.” That fuzzy number, perhaps written in passive voice for a reason, might be correct. But it depends upon how you count…”

For many years, the word “drone” was used only infrequently by bee enthusiasts, bagpipe players, and people subjected to monotonous music. However, in recent years it has taken on a new and controversial meanings associated with pilotless aircraft.
For many, the word is steeped in controversies that stem from its military uses in conflict zones. For others, it calls up images of gadgets like that of the small-unmanned helicopter in Amazon’s recent YouTube video, which delivers bulky packages to the doorsteps of happy customers. Few people know that a group of scientists in the Himalayas is using drones (or Unmanned Aerial Vehicles) to fly a different kind of mission, related to glaciers.
Along with researchers from Utrecht University in the Netherlands, scientists at the International Center for Integrated Mountain Development (ICIMOD), a sustainable development organization based in Nepal, have been sending up UAVs to map previously uncharted glaciers in some of the most inaccessible regions of the Himalayas.
The two research groups have been mapping Lirung Glacier with UAVs equipped with GPS devices and cameras since 2013. Though it could seem daunting to assemble, program and operate a flying robot, this method is relatively simple and robust. The researchers input a route for the drone to fly, and then program it to take pictures at predetermined points of interest along the way. Once the flight is complete, researchers stitch the photos together, often including those from previous flights, to make a complete map of the area.
An article which describes this project, published in the journal Remote Sensing of Environment, suggests that drone- based exploration may wholly transform glacier exploration and expand our knowledge of glacial dynamics in the region. Utrecht University researcher Dr. Walter Immerzel reports that the Himalayas are losing an area of ice cover at a rate equivalent to about 9,000 sports stadiums per year (on average between 15 and 30 meters per glacier). The new data provide the researchers with a clearer picture of the location of the melting ice. The data suggest that ice cliffs and ponds on the glacier surface account for the bulk of the loss of ice from Lirung Glacier ice melt.
These findings are of social as well as scientific importance, since more than one billion people in Asia rely on rivers fed by glacial melt for their drinking water, sanitation, energy, and livelihoods. At the moment, the descriptions of glacial retreat in the Himalayas offer broad-brush accounts and rely heavily on models for their information. This, and similar projects, provides science and society with a more precise, observation-based view of specific glaciers.
However, not all glaciers follow the same pattern of retreat. Consequently, the research group has plans to extend their technique to other glaciers in Nepal. Researchers hope that using UAVs to map the variation in Himalayan glaciers will provide them with the fine-grained data they need to understand and predict the future of Himalayan glaciers.
Climate Change adaptation and disaster risk reduction
“As the frequency of disasters is increasing, and more people and properties are at risk, it is time to exploit the natural resource in a way that we can contribute to reduce the global warming. Effective disaster management measures should be taken, and mass awareness, institutional mainstreaming, and integration of DRR into development are to be ensured at all level. ”
Adaptation to the Impact of Rapid Glacier Retreat in the Tropical Andes
“The development objective Adaptation to the Impact of Rapid Glacier Retreat in the Tropical Andes Project for Andean Countries is to contribute to strengthening the resilience of local ecosystems and economies to the impacts of glacier retreat in the Tropical Andes, through the implementation of specific pilot adaptation activities that illustrate the costs and benefits of adaptation.”

“Following the tragic loss of 16 Nepali mountaineering workers during the Mt. Everest avalanche on 18 April 2014, there has been a clear need for reflection and reform in Nepal’s mountaineering industry.”
Glacial Melt Pours Iron into Ocean, Seeding Algal Blooms
Scientists report in a new study this week that glacial melt may be funneling significant amounts of reactive iron into the ocean, where it may counter some of the negative effects of climate change by boosting algal blooms that capture carbon.
