Near‐Bed Flow Turbulence Beneath Ice Cover Under Varying Hydrological Conditions: A 9‐Year Field Measurement‐Based Analysis From a Meander Bend

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Climate change alters hydrological and ice conditions, but how these changes affect turbulence beneath ice cover has been poorly studied. This study presents a multi‐year observational analysis of near‐bed turbulence under ice cover in a subarctic meandering river reach.

STUDY ON SNOWSTORM-INDUCED INCREASES IN FRAZIL SLUSH AND THE IDENTIFICATION OF POTENTIAL ICE JAM LOCATIONS ON THE OSOBETSU RIVER [PDF]

, 2016
In December 2014, an ice jam occurred on the Osobetsu River after a snowstorm. This study investigated factors that contribute to increases in frazil slush and identified locations prone to ice jams.

Considerations on Recent Freezing Phenomena on Bistriţa and Bistricioara Rivers

Present Environment and Sustainable Development, 2014
It is highly important to have a better knowledge of river systems during the seasons when air temperature drops below freezing point if we consider the difficulties posed to hydrotechnical exploitations and the destruction caused by floods (as a result ...

Antarctic Meltwater Accelerates Southern Ocean Evolution Under Projected Atmospheric Warming

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Increasing basal meltwater from Antarctic ice shelves may impact the Southern Ocean properties that feed back on the rate of melting. We investigate this feedback in a high‐emissions scenario using an Earth‐system model with interactive ice‐shelf basal melting, an improvement on previous studies that did not have the capability to evolve melt ...

A tabulated review of 83 laboratory studies on frazil ice

, 2020
Frazil ice is a term used to designate ice particles of various shape occurring in a turbulent and supercooled water column, in both freshwater and saline water bodies. That ice is known to promote flooding, and also tends to clog water intakes and other

Basal Melting Variability of the Ross Ice Shelf From Mixing Ratios of Simulated Water Masses (1993–2018) and Potential Climatic Drivers

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Several water masses circulate under the Ross Ice Shelf (RIS), the largest ice shelf in Antarctica, each causing basal melting with a specific spatio‐temporal pattern. To investigate these patterns and their variability, we applied a mixing ratio analysis to simulated water masses from a new numerical ocean model of the Ross Sea.

Wind Forcing and Warm Water Upwelling in a Recurring Beaufort Shelf Polynya

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract The Beaufort Shelf has historically been reported to exhibit limited polynya activity in winter. Yet, recent satellite observations show episodic recurrence of a large polynya west of Mackenzie Canyon, a site of significant shelf‐basin exchange.

Impact of a New Sea Ice Thermodynamic Formulation in the CESM2 Sea Ice Component

Journal of Advances in Modeling Earth Systems, 2020
The sea ice component of the Community Earth System Model version 2 (CESM2) contains new “mushy‐layer” physics that simulates prognostic salinity in the sea ice, with consequent modifications to sea ice thermodynamics and the treatment of melt ponds. The

Dissolved Organic Matter Composition in the Laurentian Great Lakes Ice and Its Contribution to Spring Melt

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Dissolved organic matter (DOM) plays a vital role in lakes, but its behavior in winter is poorly understood. This study examined the differences in DOM between lake ice and the upper water column across 18 sites in the Laurentian Great Lakes, integrating in situ sampling and remotely sensed ice data to create a mass budget model to estimate ...
