Frazil Ice in the Antarctic Marginal Ice Zone [PDF]

Journal of Marine Science and Engineering, 2021
Frazil ice, consisting of loose disc-shaped ice crystals, is the first ice that forms in the annual cycle in the marginal ice zone (MIZ) of the Antarctic.

Three-dimensional imaging of waves and floes in the marginal ice zone during a cyclone [PDF]

Nature Communications, 2022
Unprecedented 3D imaging of waves and sea ice floes from a moving icebreaker in the Antarctic marginal ice zone during a polar cyclone reveals a complex wind-plus-swell sea state, where contrasting ice-driven attenuation and wind forcing coexist.

Granular effects in sea ice rheology in the marginal ice zone [PDF]

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2022
Sea ice in the marginal ice zone (MIZ) consists of relatively small floes with a wide size span. In response to oceanic and atmospheric forcing, it behaves as an approximately two-dimensional, highly polydisperse granular material. The established viscous-plastic rheologies used in continuum sea ice models are not suitable for the ...

Marginal ice zone dynamics: future research perspectives and pathways [PDF]

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2022
Perspectives are discussed on future directions for the field of marginal ice zone (MIZ) dynamics, based on the extraordinary progress made over the past decade in its theory, modelling and observations.

Marginal ice zone fraction benchmarks sea ice and climate model skill [PDF]

Nature Communications, 2021
Climate models struggle to track the response of Arctic sea ice to warming, leading to efforts to improve sea-ice models. Here the author shows standard model metrics are poor judges of the impact of model improvements, but a new one, marginal ice zone ...

Svalbard Marginal Ice Zone 2024: A distributed network of temperature, waves, and sea ice drift observations [PDF]

Scientific Data
The coupling of weather, sea-ice, ocean, and wave forecasting systems has been a research priority for improving Arctic prediction capabilities. However, the complexity of the underlying physical processes and the difficulty of obtaining observations on ...

SAR Observation of Waves under Ice in the Marginal Ice Zone

Journal of Marine Science and Engineering, 2022
The marginal ice zone (MIZ) connects the open ocean and the pack ice, playing significant roles in shaping the ice edge and wave–ice interaction. Spaceborne synthetic aperture radar (SAR) has been demonstrated to be one of the most advantageous sensors ...

Revealing the Antarctic marginal ice zone with a decade-long wave-in-ice climatology [PDF]

Nature Communications
The marginal ice zone (MIZ) is the region of sea ice that is strongly influenced by open-ocean processes, particularly ocean waves. The width of the Antarctic MIZ is often quantified by applying thresholds to satellite-derived maps of sea-ice ...

Nitrogen fixation under declining Arctic sea ice [PDF]

Communications Earth & Environment
With climate change-induced sea ice decline in the Arctic Ocean, nitrogen is expected to become an increasingly important determinant of primary productivity.

Multiscale mushy layer model for Arctic marginal ice zone dynamics [PDF]

Scientific Reports
Perhaps the most dynamic component of the Arctic sea ice cover is the marginal ice zone (MIZ), the transitional region between dense pack ice to the north and open ocean to the south.
