PHOTOGRAMMETRIC MONITORING OF GLACIER MARGIN LAKES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 Abstract. The growing number of glacial margin lakes that have developed due to glacier retreat, have caused an increase of dangerous Glacial Lake Outburst Floods (GLOFs) in several regions over the last decade. A GLOF can occur when the water from the lake finds a path underneath the bottom of the glacier and the lake is draining rapidly.

Combining UAV and Landsat data to assess glacier changes on the central Tibetan Plateau
Journal of Glaciology, 2021 In recent years, researchers have focused on the applications of uncrewed aerial vehicles (UAVs) in environmental remote sensing tasks. However, studies on glacier monitoring using UAV technology are relatively scarce, especially for high mountain ...

Monitoring Glacier Calving using Underwater Sound
The Cryosphere, 2023 Abstract. Climate shifts are particularly conspicuous in the Arctic. Satellite and terrestrial observations show significant increases in the melting and breakup of Arctic tidewater glaciers and their influence on sea level rise. Increasing melt rates are creating an urgency to better understand the link between atmospheric and oceanic conditions and ...

A new index of glacier area change: a tool for glacier monitoring [PDF]
Journal of Glaciology, 2009 AbstractSince the mid-19th century, most glaciers have been losing area and volume. This loss of area has not been homogeneous in time and space, and direct observations are sparse, making regional and global estimates of glacier change difficult.

Glacier Motion Monitoring Using a Novel Deep Matching Network with SAR Intensity Images
Remote Sensing, 2022 Synthetic Aperture Radar technology is highly convenient for monitoring the glacier surface motion in unfavorable areas due to its advantages of being independent of time and weather conditions.

GLACIER SURFACE MONITORING BY MAXIMIZING MUTUAL INFORMATION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Abstract. The contribution of Polarimetric Synthetic Aperture Radar (PolSAR) images compared with the single-channel SAR in terms of temporal scene characterization has been found and described to add valuable information in the literature. However, despite a number of recent studies focusing on single polarized glacier monitoring, the potential of ...

Proceedings of the Indian National Science Academy, 2017 Polar ice is an important component of the natural system, affecting global climate on large as well as small scale. The Antarctic ice sheet has undergone significant changes in the past and governed the earth’s climatic system. This ice sheet appears to have been very dynamic and yet, not much is known about the processes involved for this dynamism ...

Glacier monitoring by satellite
Il Nuovo Cimento C, 1983 A multitemporal analysis on the Mount Disgrazia glaciers was performed by using the 1975, 1978 and 1980 MSS Landsat images. On these images the glaciers were completely described in their boundaries and surface features. Fixed structures were used along their boundaries as fiducial points of the ground control table for the multitemporal comparison of ...
