Coherent scatterers detection: application over glacier terrain using TerraSAR-X time series data [PDF]

, 2011
This paper investigates the detection of Coherent Scatterers (CSs) in ice and glacier terrain by means of TerraSAR-X time series data in the test site of the Helheim Glacier in Greenland.

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

Journal 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

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

Geografia 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.

The distribution of basal motion beneath a High Arctic polythermal glacier [PDF]

, 2003
The longitudinal pattern of surface velocity of a large, predominantly colds polythermal glacier (John Evans Glacier, Ellesmere Island, Canada) was measured over summer and winter periods.

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

Annals 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.

Spectral roughness of glaciated bedrock geomorphic surfaces: Implications for glacier sliding [PDF]

, 2000
A microroughness meter (MRM) was used to measure the high-frequency roughness of a number of geomorphic surfaces in the forefield of Glacier de Tsanfleuron, Switzerland.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

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

Annals 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

Upcycling Keratin‐Based Textile Waste Into High‐Performance Hybrid Fibers Via Tuning the Interfacial Interactions

Advanced Functional Materials, EarlyView.
Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.

Rapid Microwave Plasma Engineering of HfO2/C@C Core‐Shell Fibrous Membrane Toward Flexible High‐Performance Electromagnetic Wave Absorption

Advanced Functional Materials, EarlyView.
Rapid microwave plasma torch engineering tunes crystal phases, carbon graphitization and oxygen‐vacancy defects in HfO2/C@C core‐shell fibrous membranes. Synergistic multi‐loss effects optimize impedance matching to deliver −65.75 dB reflection loss and a 7.37 GHz effective bandwidth for flexible electromagnetic wave absorption.
