Particle, kinetic and hydrodynamic models for sea ice floes. Part II: Rotating floes with environmental forces
Quanling Deng, Seung-Yeal Ha, Jaemoon Lee +2
This paper builds on the multiscale modeling framework introduced in Part I (Deng and Ha, Physica D: Nonlinear Phenomena 483 (2025) 134951) for sea-ice floe dynamics with non-rotat…
Wave Attenuation in Drifting Sea Ice: A Mechanistic Model for Observed Decay Profiles
Rhys Ransome, Davide Proment, Ian A. Renfrew +1
Wave-sea ice interactions shape the transition zone between open ocean and pack ice in the polar regions. Most theoretical paradigms, implemented in coupled wave-sea ice models, pr…
Fine-Scale Heterogeneity of Snow Cover in the Antarctic Marginal Ice Zone
Ippolita Tersigni, Filippo Nelli, Emiliano Cimoli +6
Snow cover on Antarctic sea ice is highly heterogeneous, yet climate models have historically simplified it to a uniform layer in winter and bare ice in summer, introducing uncerta…
Parameter-free higher-order Schrodinger systems with weak dissipation and forcing
Jack Keeler, Alberto Alberello, Ben Humphries +1
The higher-order nonlinear Schrodinger equation (Dysthe's equation in the context of water-waves) models the time evolution of the slowly modulated amplitude of a wave-packet in di…
Sea ice floe segmentation in close-range optical imagery using active contour and foundation models
Giulio Passerotti, Alberto Alberello, Marcello Vichi +3
The size of sea ice floes in the marginal ice zone (MIZ) is a key factor influencing ice coverage, albedo, wave propagation, and ocean--atmosphere energy exchanges. Floe size can b…
Modulational instability of nonuniformly damped, broad-banded waves: applications to waves in sea-ice
Raphael Stuhlmeier, Conor Heffernan, Alberto Alberello +1
This paper sets out to explore the modulational (or Benjamin-Feir) instability of a monochromatic wave propagating in the presence of damping such as that induced by sea-ice on the…
Observations of rogue seas in the Southern Ocean
Alessandro Toffoli, Alberto Alberello, Hans Clarke +6
We report direct observations of surface waves from a stereo camera system along with concurrent measurements of wind speed during an expedition across the Southern Ocean in the au…
A dissipative Nonlinear Schrödinger model for wave propagation in the marginal ice zone
Alberto Alberello, Emilian Parau
Sea ice attenuates waves propagating from the open ocean. Here we model the evolution of energetic unidirectional random waves in the marginal ice zone with a nonlinear Schrödinger…
Interactions between irregular wave fields and sea ice: A physical model for wave attenuation and ice breakup in an ice tank
Giulio Passerotti, Luke G. Bennetts, Franz von Bock und Polach +5
Irregular, unidirectional surface water waves incident on model ice in an ice tank are used as a physical model of ocean surface wave interactions with sea ice. Results are given f…
A computational fluid dynamics model for the small-scale dynamics of wave, ice floe and interstitial grease ice interaction
Rutger Marquart, Alfred Bogaers, Sebastian Skatulla +4
The marginal ice zone is a highly dynamical region where sea ice and ocean waves interact. Large-scale sea ice models only compute domain-averaged responses. As the majority of the…
Three-dimensional imaging of waves and floe sizes in the marginal ice zone during an explosive cyclone
Alberto Alberello, Luke Bennetts, Miguel Onorato +11
The marginal ice zone is the dynamic interface between the open ocean and consolidated inner pack ice. Surface gravity waves regulate marginal ice zone extent and properties, and,…
Fourier Amplitude Distribution and Intermittency in Mechanically Generated Surface Gravity Waves
Elmira Fadaeiazar, Justin Leontini, Miguel Onorato +3
We examine and discuss the spatial evolution of the statistical properties of mechanically generated surface gravity wave fields, initialised with unidirectional spectral energy di…
Drift of pancake ice floes in the winter Antarctic marginal ice zone during polar cyclones

Wave turbulence and intermittency in directional sea states
Elmira Fadaeiazar, Alberto Alberello, Miguel Onorato +4
The evolution of surface gravity waves is driven by nonlinear interactions that trigger an energy cascade similarly to the one observed in hydrodynamic turbulence. This process, kn…
An experimental comparison of velocities underneath focussed breaking waves
Alberto Alberello, Amin Chabchoub, Jason Monty +4
Nonlinear wave interactions affect the evolution of steep wave groups, their breaking and the associated kinematic field. Laboratory experiments are performed to investigate the ef…
Observation of turbulence in wave-induced oscillatory flows
Alberto Alberello, Federico Frascoli, Miguel Onorato +1
The dynamic and thermal regimes of climate are regulated by an exchange of energy and momentum between the atmosphere and the ocean. The role exerted by surface waves on this inter…
