The National Research Council of Canada’s large-scale frazil ice facility

, 2023
Frazil ice particles form in supercooled turbulent waters. Frazil ice is known for clogging the water intakes of infrastructure such as municipal water supplies or power generating facilities. It also has the potential to cause flooding events.

From Glacier to Coast: Seasonal Hydrographic Dynamics in the Ella Ø Fjord Complex, East Greenland

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Greenland's ice loss is increasing across the ice sheet due to enhanced surface melting and accelerated glacier discharge, contributing to sea level rise and potentially altering ocean circulation and marine ecosystems. Fjords play a key role in this process by linking the ocean and ice sheet, but currently a limitation is that most fjords in ...

FloeNet: A Mass‐Conserving Global Sea Ice Emulator That Generalizes Across Climates

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We introduce FloeNet, a graph neural network trained to emulate the Geophysical Fluid Dynamics Laboratory global sea ice model, SIS2. FloeNet is a mass‐conserving model, emulating 6‐hr mass and area budget tendencies related to sea ice and snow‐on‐sea‐ice growth, melt, and advection.

Comprehensive two-dimensional river ice model based on boundary-fitted coordinate transformation method

Water Science and Engineering, 2014
River ice is a natural phenomenon in cold regions, influenced by meteorology, geomorphology, and hydraulic conditions. River ice processes involve complex interactions between hydrodynamic, mechanical, and thermal processes, and they are also influenced ...

COMPARISON OF C-BAND AND X-BAND POLARIMETRIC SAR DATA FOR RIVER ICE CLASSIFICATION ON THE PEACE RIVER [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
In this study, synthetic aperture radar (SAR) data from TerraSAR-X were compared with RADARSAT-2 data to evaluate their effectiveness for river ice monitoring on the Peace River. For several years RADARSAT-2 data have been successfully used for river ice

River Ice Analyses and Roughness Calculations Using Underwater Drones and Photogrammetric Approach

Hydrological Processes, Volume 40, Issue 7, July 2026.
This study presents a methodology for determining hydraulic roughness (Manning's n) of fluvial ice using underwater drone and Structure from Motion (SfM) photogrammetry. The findings show that cost‐efficient equipment can be used to determine Manning's n for river ice, which supports modelling efforts, especially under intense warming in northern areas.

The Evidence for Linearly Scaling Ocean Gas Exchange With Sea Ice Needs Strengthening

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Polar oceans are critical components of the oceanic uptake of atmospheric carbon dioxide. Estimates of this uptake across the air‐sea interface require parameterizations of gas transfer velocity that account for variable sea ice concentrations.

Measurements of wave damping by a grease ice slick in Svalbard using off-the-shelf sensors and open-source electronics

Journal of Glaciology, 2017
Versatile instruments assembled from off-the-shelf sensors and open-source electronics are used to record wave propagation and damping measured by Inertial Motion Units (IMUs) in a grease ice slick near the shore in Adventfjorden, Svalbard.
