Automatic delineation of glacier grounding lines in differential interferometric synthetic-aperture radar data using deep learning [PDF]
Scientific Reports, 2021 AbstractDelineating the grounding line of marine-terminating glaciers—where ice starts to become afloat in ocean waters—is crucial for measuring and understanding ice sheet mass balance, glacier dynamics, and their contributions to sea level rise. This task has been previously done using time-consuming, mostly-manual digitizations of differential ...

An automatic approach to delineate the cold–temperate transition surface with ground-penetrating radar on polythermal glaciers [PDF]
Annals of Glaciology, 2014 AbstractGround-penetrating radar has been widely used to map the thermal structure of polythermal glaciers. Hitherto, the cold–temperate transition surface (CTS) in radargrams has been identified by a labour-intensive and subjective manual picking method. We introduce a new automatic approach for picking the CTS that uses the difference in signal power

Slight change of glaciers in the Pamir over the period 2000–2017
Arctic, Antarctic, and Alpine Research, 2022 Glaciers in the Pamir are the water tower of arid Central Asia, and more than 50 million people depend on meltwater from them. Many studies have reported glacier changes in the Pamir, but the glacier inventories employed in the previous investigations ...

Delineation of Glacier Drainage Basins on Western Vatnajokull [PDF]
Annals of Glaciology, 1986 Three ice-drainage basins on western Vatnajökull have been delineated with the aid of the first available, accurate ice-surface maps. These basins drain ice towards the major river systems: Tungnaá, Sylgja, and Kaldakvísl, There seems to be an important difference in the location of ice-drainage basins and melt water-drainage basins for the rivers ...

Using L-band SAR coherence to delineate glacier extent
Canadian Journal of Remote Sensing, 2010 Significant retreat has been seen in many glaciers worldwide. With increasing concern about the impact of global warming, there has been a concerted effort to monitor ongoing change. Projects such as Global Land Ice Measurements from Space (GLIMS) rely on the contributions of institutions worldwide to update a global database of digital glacier ...

Delineation of a complexly dipping temperate glacier bed using short-pulse radar arrays [PDF]
Journal of Glaciology, 2000 AbstractWe have defined the complex bed topography for a section of a small temperate glacier using 50 MHz monostatic short-pulse radar data and a synthetic-aperture array-processing method. The data were collected on a 100 m by 340 m array grid in the upper stem of Gulkana Glacier, central Alaska, U.S.A.

, 2022 The temporal variability in calving front positions of marine-terminating glaciers permits inference on the frontal ablation. Frontal ablation, the sum of the calving rate and the melt rate at the terminus, significantly contributes to the mass balance ...

Using a Web Map Service to map Little Ice Age glacier extents at regional scales
Annals of Glaciology, 2023 Extending the record of glacier area changes into the past improves our understanding of climate change impacts. Although analogue maps showing historic glacier extents are abundant, digital outlines from before the satellite era are sparse as the ...
