Status and Change of the Cryosphere in the Extended Hindu Kush Himalaya Region

The Hindu Kush Himalaya Assessment, 2019
The cryosphere is defined by the presence of frozen water in its many forms: glaciers, ice caps, ice sheets, snow, permafrost, and river and lake ice.

Pigment production by cold-adapted bacteria and fungi: colorful tale of cryosphere with wide range applications

Extremophiles, 2020
Pigments are an essential part of everyday life on Earth with rapidly growing industrial and biomedical applications. Synthetic pigments account for a major portion of these pigments that in turn have deleterious effects on public health and environment.

Watching the Cryosphere Thaw: Seismic Monitoring of Permafrost Degradation Using Distributed Acoustic Sensing During a Controlled Heating Experiment

Geophysical Research Letters, 2022
Permafrost degradation is rapidly increasing in response to a warming Arctic climate, altering landscapes and damaging critical infrastructure. Solutions for monitoring permafrost thaw dynamics are essential to understand biogeochemical feedbacks as well

Consequences of the 2019 Greenland Ice Sheet Melt Episode on Albedo

Remote Sensing, 2021
In mid-June 2019, the Greenland ice sheet (GrIS) experienced an extreme early-season melt event. This, coupled with an earlier-than-average melt onset and low prior winter snowfall over western Greenland, led to a rapid decrease in surface albedo and ...

The Global Social and Economic Consequences of Mountain Cryospheric Change

Frontiers in Environmental Science, 2019
The mountain cryosphere provides fresh water and other ecosystem services to half of humanity. The loss of the mountain cryosphere due to global warming is already evident in many parts of the world and has direct implications to people living in ...

Remote Sensing and Modeling of the Cryosphere in High Mountain Asia: A Multidisciplinary Review

Remote Sensing
Over the past decades, the cryosphere has changed significantly in High Mountain Asia (HMA), leading to multiple natural hazards such as rock–ice avalanches, glacier collapse, debris flows, landslides, and glacial lake outburst floods (GLOFs). Monitoring
