MULTI-TEMPORAL AND MULTI-SENSOR GLACIER MONITORING

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
Abstract. Glaciers are subject to drastic mass loss in the last decades and their importance as an environmental and hydrological resource requires regular monitoring. Geomatics techniques are the ideal tool to survey these complex and remote areas, with different remote sensing platforms and sensors to choose from depending on the scale and accuracy ...

Vanishing of the Glacier Yanamarey, one of the four glaciers with in situ measurements in the Cordillera Blanca, Peru

Annals of Glaciology
The Tropical Andes stand out as one of the mountain regions most affected by global warming. Here, we present a synthesis of recent glacier evolution in the Cordillera Blanca, based on the glaciers that have been monitored with in situ glaciological ...

Regional passive seismic monitoring reveals dynamic glacier activity on Spitsbergen, Svalbard [PDF]

Polar Research, 2015
Dynamic glacier activity is increasingly observed through passive seismic monitoring. We analysed near-regional-scale seismicity on the Arctic archipelago of Svalbard to identify seismic icequake signals and to study their spatial–temporal distribution ...

Classification and kinematics of the Planpincieux Glacier break-offs using photographic time-lapse analysis

Journal of Glaciology, 2020
Herein, we present results obtained from time-lapse imagery acquired by a digital single-lens reflex camera during 2014–18 used to monitor the Planpincieux Glacier on the Italian side of the Grandes Jorasses (Mont Blanc massif).

Glacier area changes in Novaya Zemlya from 1986–89 to 2019–21 using object-based image analysis in Google Earth Engine

Journal of Glaciology, 2023
Climate change has had a significant impact on glacier recession, particularly in the Arctic, where glacier meltwater is an important contributor to global sea-level rise.

Closely monitored glaciers

, 2020
Glaciers in tropical and subtropical regions are characterised by specific functions. Their response to global warming cannot be extrapolated from the observations of mid-latitude or polar latitude glaciers alone.

A Bibliometric and Visualized Analysis of Remote Sensing Methods for Glacier Mass Balance Research

Remote Sensing, 2023
In recent decades, climate change has led to global warming, glacier melting, glacial lake outbursts, sea level rising, and more extreme weather, and has seriously affected human life.

Enhanced Wide-Area Glacier Velocity Monitoring in Svalbard via Synthetic Aperture Radar Offset Tracking Noise Suppression

Applied Sciences
Glacier movement is an important indicator of climate change, reflecting the quality and state changes in glacier migration and mass balance in the context of global warming.
