Combined use of multi-source satellite imagery and deep learning for automated mapping of glacial lakes in the Bhutan Himalaya

Science of Remote Sensing
Himalayan glacial lakes have been rapidly developing and expanding in recent decades under climate change and glacier mass loss. These growing glacial lakes can produce glacial lake outburst floods (GLOFs) events with far-reaching and devastating ...

Routing of western Canadian Plains runoff during the 8.2 ka cold event [PDF]

, 2009
The collapse of the Laurentide Ice Sheet over Hudson Bay ∼8.47 ka allowed the rapid drainage of glacial Lake Agassiz into the Labrador Sea, an event identified as causing a reduction in Atlantic meridional overturning circulation (AMOC) and the 8.2 ka ...

AutoChamber: A broadly accessible 3D‐printed floating chamber to automate measurements of greenhouse gas emissions from surface waters

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 979-991, March 2026.
Abstract Fresh waters provide environmental conditions that favour microbial CO2 and CH4 production, leading to the release of large quantities of greenhouse gases (GHG) to the atmosphere. Despite their importance, these fluxes remain poorly defined, weakening estimates of global GHG budgets that are critical in implementing effective climate ...

Glacial lake expansion in the central Himalayas by Landsat images, 1990-2010. [PDF]

PLoS ONE, 2013
Glacial lake outburst flood (GLOF) is a serious hazard in high, mountainous regions. In the Himalayas, catastrophic risks of GLOFs have increased in recent years because most Himalayan glaciers have experienced remarkable downwasting under a warming ...

Seasonal variations in proglacial lake area revealed by high spatial resolution planetscope satellite imagery

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
High‐resolution PlanetScope imagery reveals seasonal variations in proglacial lake area are underestimated by ~7% in moderate‐resolution data, while use of a single summer image can underestimate annual maximum area by ~2%. Capturing these seasonal variations provides valuable insights into the factors driving lake dynamics at Fjallsárlón, Iceland ...

First approaches towards modelling glacial hazards in the Mount Cook region of New Zealand’s Southern Alps [PDF]

, 2009
Flood and mass movements originating from glacial environments are particularly devastating in populated mountain regions of the world, but in the remote Mount Cook region of New Zealand’s Southern Alps minimal attention has been given to these processes.

Long‐Term Snow Avalanche Trends in High Mountain Asia: Climatic Drivers and Impacts

Earth's Future, Volume 14, Issue 2, February 2026.
Abstract Devastating snow avalanches are frequent in High Mountain Asia (HMA) yet remain undocumented with climate change impact drivers poorly understood. Here we introduce the first record of 60 million avalanche deposits across 10,701 small catchments, compiled from 33 years of Landsat data from 1990 until 2022 using a snow index.

Analysis of triggering factors behind the October 2023 South Lhonak GLOF event in the Sikkim Himalaya using multiple remote sensing data

Geomatics, Natural Hazards & Risk
A catastrophic Glacial Lake Outburst Flood (GLOF) occurred from the South Lhonak Glacial Lake (SLGL) in the Sikkim Himalaya between October 3 and 4, 2023, highlighting the urgent need to understand its triggering mechanisms.

A glacial lake outburst flood risk assessment for the Phochhu river basin, Bhutan [PDF]

Natural Hazards and Earth System Sciences
The melting of glaciers has led to an unprecedented increase in the number and size of glacial lakes, particularly in the Himalayan region. A glacial lake outburst flood (GLOF) is a natural hazard in which water from a glacial or glacier-fed lake is ...

Morphological properties of tunnel valleys of the southern sector of the Laurentide Ice Sheet and implications for their formation [PDF]

, 2016
Tunnel valleys have been widely reported on the bed of former ice sheets and are considered an important expression of subglacial meltwater drainage.
