Delineation of debris-covered glacier boundaries using optical and thermal remote sensing data

Remote Sensing Letters, 2010
The varying extent of debris cover on a glacier's boundary may seriously hinder automated mapping and inventorying of glaciers in various parts of the world. The problem arises because supraglacial debris (i.e. debris on the glacier) and the adjacent periglacial debris (occurring outside the glacier boundary) have a similar spectral response in the ...

Drainage basin delineation for outlet glaciers of Northeast Greenland based on Sentinel-1 ice velocities and TanDEM-X elevations

Remote Sensing of Environment, 2020
Abstract The drainage divides of ice sheets separate the overall glaciated area into multiple sectors. These drainage basins are essential for partitioning mass changes of the ice sheet, as they specify the area over which basin specific measurements are integrated.

Automated Extraction of Antarctic Glacier and Ice Shelf Fronts from Sentinel-1 Imagery Using Deep Learning

Remote Sensing, 2019
Sea level rise contribution from the Antarctic ice sheet is influenced by changes in glacier and ice shelf front position. Still, little is known about seasonal glacier and ice shelf front fluctuations as the manual delineation of calving fronts from ...

Analysis of continuous calving front retreat and the associated influencing factors of the Thwaites Glacier using high-resolution remote sensing data from 2015 to 2023

International Journal of Digital Earth
The Thwaites Glacier (TG), accounting for four percent of present-day sea-level rise, has been confirmed with the irreversible retreat and thinning. Consequently, understanding the continuous calving front retreat within the TG is pivotal for accurately ...

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).

A new global gridded glacier dataset based on the Randolph Glacier Inventory version 6.0

Journal of Glaciology, 2021
Gridded glacier datasets are essential for various glaciological and climatological research because they link glacier cover with the corresponding gridded meteorological variables.

Which glaciers are the largest in the world?

Journal of Glaciology, 2023
Glacier monitoring has been internationally coordinated for more than 125 years. Despite this long history, there is no authoritative answer to the popular question: ‘Which glaciers are the largest in the world?’ Here, we present the first systematic ...

AMD-HookNet for Glacier Front Segmentation [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2023
Knowledge on changes in glacier calving front positions is important for assessing the status of glaciers. Remote sensing imagery provides the ideal database for monitoring calving front positions; however, it is not feasible to perform this task ...

A Deep Active Contour Model for Delineating Glacier Calving Fronts [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2023
Choosing how to encode a real-world problem as a machine learning task is an important design decision in machine learning. The task of the glacier calving front modeling has often been approached as a semantic segmentation task.
