Serpentine (Floating) Ice Channels and their Interaction with Riverbed Permafrost in the Lena River Delta, Russia

open access: yesFrontiers in Earth Science, 2021
Arctic deltas and their river channels are characterized by three components of the cryosphere: snow, river ice, and permafrost, making them especially sensitive to ongoing climate change. Thinning river ice and rising river water temperatures may affect

Quantifying the Effect of River Ice Surface Roughness on Sentinel-1 SAR Backscatter

open access: yesRemote Sensing, 2022
Satellite-based C-band synthetic aperture radar (SAR) imagery is an effective tool to map and monitor river ice on regional scales because the SAR backscatter is affected by various physical properties of the ice, including roughness, thickness, and ...

River Ice Segmentation With Deep Learning [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2020
This paper deals with the problem of computing surface ice concentration for two different types of ice from digital images of river surface. It presents the results of attempting to solve this problem using several state of the art semantic segmentation methods based on deep convolutional neural networks (CNNs). This task presents two main challenges -
