Dangerous Glacial Lakes Identification With Property-Spatial Associations in High Mountain Asia From 1990 to 2022

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Glacial lakes are among the most sensitive indicators of climate change. With the ongoing climate warming, the number and area of glacial lakes are dramatically increased, particularly in High Mountain Asia (HMA), thereby concomitantly arousing the ...

Refined glacial lake extraction in a high-Asia region by deep neural network and superpixel-based conditional random field methods [PDF]

open access: yesThe Cryosphere
Remote sensing extraction of glacial lakes is an effective way of monitoring water body distribution and outburst events. At present, the lack of glacial lake datasets and the edge recognition problem of semantic segmentation networks lead to poor ...

Inventory and Spatiotemporal Patterns of Glacial Lakes in the HKH-TMHA Region from 1990 to 2020

open access: yesRemote Sensing, 2022
The Himalayan, Karakoram, and Hindu Kush (HKH-TMHA) are the three main mountain ranges in the high-mountain Asia region, covering the China–Pakistan Economic Corridor (CPEC).

Mapping of glacial lakes using Sentinel-1 and Sentinel-2 data and a random forest classifier: Strengths and challenges

open access: yesScience of Remote Sensing, 2020
Glacial lakes pose a serious threat to downstream areas and significantly impact glacier melt. The number and area of lakes has grown in most regions during the last decades due to the ongoing atmospheric warming and retreating glaciers.

Spatio-Temporal Evolution of Glacial Lakes in the Tibetan Plateau over the Past 30 Years

open access: yesRemote Sensing, 2023
As the Third Pole of the Earth and the Water Tower of Asia, the Tibetan Plateau (TP) nurtures large numbers of glacial lakes, which are sensitive to global climate change.

Glacial lake mapping: Progress, challenges, and future directions

open access: yesArctic, Antarctic, and Alpine Research
Glacial lakes are a critical water resource, an indicator of climate change, and a potential source for glacial lake outburst floods. Accurate and frequent mapping is important for understanding glacial lake dynamics and associated hazards, particularly ...

Reconstructing ice-sheet accumulation rates at ridge B, East Antarctica [PDF]

open access: yes, 2004
Understanding how ice sheets responded to past climate change is fundamental to forecasting how they will respond in the future. Numerical models calculating the evolution of ice sheets depend upon accumulation data, which are principally available from ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

open access: yesMolecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Evidence of climate change - Investigating glacial terminus and lake inventory using earth observation data for mountainous Bhutan

open access: yesScience of Remote Sensing
The mapping and monitoring of different types of Glacial lakes through the Geospatial techniques is vital to show the impact of climate changes on the Glacier and alleviate hazards that result from the bursting of Glacial Lakes and cause catastrophic ...
