Debris cover and the thinning of Kennicott Glacier, Alaska: in situ measurements, automated ice cliff delineation and distributed melt estimates [PDF]
Cryosphere, 2021 Many glaciers are thinning rapidly beneath melt-reducing debris cover, including Kennicott Glacier in Alaska where glacier-wide maximum thinning also occurs under debris.

Delineation of Radar Glacier Zones in the Antarctic Peninsula Using Polarimetric SAR [PDF]
Water (Switzerland), 2020 Climate change is a cause of the expansion of snowmelt phenomena in the Antarctic, and shifts in position of wet and dry snow lines have been considered as good indicators of climate changes. The impacts of climate change are observable by the delineation of significant position change of glacier zones.

CONCEPTUAL FRAMEWORK OF COMBINED PIXEL AND OBJECT-BASED METHOD FOR DELINEATION OF DEBRIS-COVERED GLACIERS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 Delineation of the glacier is an important task for understanding response of glaciers to climate. In Himalayan region, most of the glaciers are covered with debris.

How to Get the Most Out of U-Net for Glacier Calving Front Segmentation
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 The melting of ice sheets and glaciers is one of the main contributors to global sea-level rise. Hence, continuous monitoring of glacier changes and in particular the mapping of positional changes of their calving front is of significant importance. This

A New Drainage Basin Delineation For The Southern Patagonian Ice Field Based On Terrasar-X Velocities And Tandem-X Elevations [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 The drainage basins or catchments for the Patagonian Ice Field are part of glacier inventories like the Randolph Glacier Inventory (RGI) or the Global Land Ice Measurements from Space (GLIMS).

Automatic delineation of debris-covered glaciers using InSAR coherence derived from X-, C- and L-band radar data: a case study of Yazgyl Glacier [PDF]
Journal of Glaciology, 2018 Despite their importance for mass-balance estimates and the progress in techniques based on optical and thermal satellite imagery, the mapping of debris-covered glacier boundaries remains a challenging task. Manual corrections hamper regular updates.

Improved Delineation of Individual Outlet Glacier Drainage Basins From Tandem-X Elevations And Sentinel-1 Velocities [PDF]
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019 Individual drainage basins of ice sheets specify the glaciated area that is drained by a single outlet glacier. These catchments are needed to partition mass balance measurements to the single glacier level. Until now complete glacier inventories that contain annotated basin information are missing for the Earth’s two ice sheets.
