Comparison of Hydrological Patterns between Glacier-Fed and Non-Glacier-Fed Lakes on the Southeastern Tibetan Plateau

open access: yesRemote Sensing, 2021
Lakes on the Tibetan Plateau have experienced variations over the last several decades, and the delineation of lake dynamics is favorable for the regional water cycle and can serve as important information for plateau environmental research.

Response of glacier flow and structure to proglacial lake development and climate at Fjallsjökull, south-east Iceland

open access: yesJournal of Glaciology, 2019
Over recent decades, the number of outlet glaciers terminating in lakes in Iceland has increased in line with climate warming. The mass-balance changes of these lake-terminating outlet glaciers are sensitive to rising air temperatures, due to altered ...

Glacier Area and Snow Cover Changes in the Range System Surrounding Tarim from 2000 to 2020 Using Google Earth Engine

open access: yesRemote Sensing, 2021
Glacier and snow are sensitive indicators of regional climate variability. In the early 21st century, glaciers in the West Kunlun and Pamir regions showed stable or even slightly positive mass budgets, and this is anomalous in a worldwide context of ...

AutoTerm: A "big data" repository of Greenland glacier termini delineated using deep learning

open access: yes, 2022
Abstract. Ice sheet marine margins via outlet glaciers are susceptible to climate change and are expected to respond through retreat, steepening, and acceleration, although with significant spatial heterogeneity. However, research on ice-ocean interactions has continued to rely on decentralized, manual mapping of features at the ice-ocean interface ...

Fusion of Sentinel-1 Interferometric Coherence and Sentinel-2 MSI for Debris-Covered Glacier Boundary Delineation: Case Study of Batura, Passu, Ghulkin, and Gulmit Glaciers, Pakistan

open access: yesGeografia Fisica e Dinamica Quaternaria, 2023
Glaciers are vital freshwater reservoirs on Earth, and Pakistan is home to some of the world's largest mid-latitude glaciers, which greatly contribute to the country's economy. The accelerated melting of glaciers worldwide due to climate change underscores the significance of regular monitoring.

Deriving a year 2000 glacier inventory for New Zealand from the existing 2016 inventory

open access: yesAnnals of Glaciology, 2023
Due to adverse snow and cloud conditions, only a few inventories are available for the maritime glaciers in New Zealand. These are difficult to compare as different approaches and baseline data have been used to create them.

Recent and future variability of the ice-sheet catchment of Sermeq Kujalleq (Jakobshavn Isbræ), Greenland

open access: yesJournal of Glaciology
Knowledge of ice-sheet catchments is critical for mass-balance assessments, especially glacier-scale input–output budgets. This study explores variations in the catchment of Sermeq Kujalleq, or Jakobshavn Isbrø, Greenland. Six observation-based catchment

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Semi-Automated Mapping of Complex-Terrain Mountain Glaciers by Integrating L-Band SAR Amplitude and Interferometric Coherence

open access: yesRemote Sensing, 2022
Mapping the outlines of glaciers has primarily relied on the interpretation of satellite optical images. However, the accurate delineation of glaciers in complex terrain mountain regions remains challenging, mainly because the supraglacial debris-covered

Vanishing and vanished glaciers. Introduction to the Annals of Glaciology Collection

open access: yesAnnals of Glaciology
We summarize and reflect on the nearly 30 studies that form this Collection on Vanishing Glaciers as a contribution to the 2025 International Year of Glaciers’ Preservation. Some of the studies in this Collection are extensions of the stories told in the
