Air-sea interactions in the marginal ice zone
Elementa: Science of the Anthropocene, 2016 The importance of waves in the Arctic Ocean has increased with the significant retreat of the seasonal sea-ice extent. Here, we use wind, wave, turbulence, and ice measurements to evaluate the response of the ocean surface to a given wind stress within ...

Modelling wave-induced sea ice break-up in the marginal ice zone [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017 A model of ice floe break-up under ocean wave forcing in the marginal ice zone (MIZ) is proposed to investigate how floe size distribution (FSD) evolves under repeated wave break-up events. A three-dimensional linear model of ocean wave scattering by a finite array of compliant circular ice floes is coupled to a flexural failure model, which breaks a ...

Microbial nitrogen cycling on the Greenland Ice Sheet [PDF]
Biogeosciences, 2012 Nitrogen inputs and microbial nitrogen cycling were investigated along a 79 km transect into the Greenland Ice Sheet (GrIS) during the main ablation season in summer 2010. The depletion of dissolved nitrate and production of ammonium (relative to icemelt)

Wave Propagation at Marginal Ice Zone
OTC Arctic Technology Conference, 2011 Abstract Moving in Artic and Sub-Artic regions imposes significant challenges on engineering aspects of offshore Oil & Gas fields development. These new developments have to be subjected to environment composed of level ice sheets, ice ridges, marginal ice zones and free sea.

Marginal ice zone dynamics. [PDF]
Philos Trans A Math Phys Eng Sci, 2022 For the best part of my entire career, I have focused on the marginal ice zone, abbreviated to MIZ by most sea ice scientists. Defined perfunctorily by the National Snow & Ice Data Center as the part of the seasonal ice zone where waves, swells and other open ocean processes affect the sea ice, the MIZ habitually extends from the ice edge some 100 ...

A Study of Wave Refraction in a Marginal Ice Zone: Frazil-Pancake Ice
IEEE Access, 2020 Theoretical estimates based on both offline calculation and an online model are made to study the wavenumber variations during wave refraction in a marginal ice zone (MIZ).

Eddy‐Induced Dispersion of Sea Ice Floes at the Marginal Ice Zone
Geophysical Research LettersOcean heat exchanges at the marginal ice zone (MIZ) play an important role in melting sea ice. Mixed‐layer eddies transport heat and ice floes across the MIZ, facilitating the pack's access to warm waters. This study explores these frontal dynamics using

Floes, the marginal ice zone and coupled wave-sea-ice feedbacks. [PDF]
Philos Trans A Math Phys Eng Sci, 2022 Marginal ice zones (MIZs) are qualitatively distinct sea-ice-covered areas that play a critical role in the interaction between the polar oceans and the broader Earth system. MIZ regions have high spatial and temporal variability in oceanic, atmospheric and ecological conditions.

WIFF1.0: a hybrid machine-learning-based parameterization of wave-induced sea ice floe fracture [PDF]
Geoscientific Model Development, 2022 Ocean surface waves play an important role in maintaining the marginal ice zone, a heterogenous region occupied by sea ice floes with variable horizontal sizes.
