Ice Dices for Monitoring Stream Surface Velocity

open access: yesJournal of Hydro-Environment Research, 2017
Abstract Non-intrusive observations are fundamental to monitor river flows and understand water processes in natural systems. Recently, the introduction of optical methods has fostered the establishment of numerous image-based techniques for characterizing the kinematics of water bodies. However, RGB image-based methods are still severely affected by

A Geomorphic and Morphometric Analysis of Surface Ice Velocity Variation of Different Valley Type Glaciers

Proceedings of SPIE, 2016
Glacier surface ice velocity is one of the important parameters which determine the glacier dynamics. If the surface ice velocity is high in upper zone (accumulation zone) of the glacier, more ice is brought to the lower zone (ablation zone) of the glacier where it melts more rapidly.

Spatio-temporal trends in the surface ice velocities of the central Himalayan glaciers, India

Global and Planetary Change, 2020
The glacier surface ice velocity (SIV) is important in understanding the glacier state. This study presents results on the SIV of the 18 glaciers spread over the Indian central Himalaya (ICH). The SIV was computed by applying Co-registration of Optically

Surface ice velocity, radar backscatter and frontal changes - links to datafiles

open access: yes, 2018
Seasonal glacier ice velocities are important for precisely estimating annual ice discharge and understanding controlling mechanisms, but these measurements for a large number of Greenlandic glaciers are limited by low temporal resolution.

Ice thickness distribution of Himalayan glaciers inferred from DInSAR-based glacier surface velocity

Environmental Monitoring and Assessment, 2022
Retrieval of glacier ice thickness is extremely important for monitoring water resources and predicting glacier dynamics and changes. The inter-annual glacier ice thickness observations (more than 5 years) exploit the glacier mass changes. Ice thickness is one of the important parameters to predict the future sea-level rise.

An Econometric Analysis of Sea Surface Temperatures, Sea Ice Concentrations and Ocean Surface Current Velocities

open access: yesJournal of Marine Science and Engineering, 2022
This paper analyzed quarterly longitudinal data for 64,800 1 × 1 degree grids during 2000–2019 on sea surface temperatures, sea ice concentrations, and ocean surface current zonal and meridional velocities in the Northern and Southern hemispheres. The methodological framework addressed the processing of remote sensing signals, interdependence between ...
