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…
Assessing the Ship Motion Prediction Capabilities of the Open-Source Model NEMOH Against Field Observations
Tianshi Yu, Ziyue Wang, Filippo Nelli +3
Accurate ship motion prediction is critical for safe and efficient maritime operations, particularly in open ocean environments. This study evaluates the capability of NEMOH, an op…
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…
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…
Model predictions of wave overwash extent into the marginal ice zone
Jordan P. A Pitt, Luke G. Bennetts, Michael H. Meylan +2
A model of the extent of wave driven overwash into fields of sea ice floes is proposed. The extent model builds on previous work modelling wave overwash of a single floe by regular…
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,…
Long-term and seasonal variability of wind and wave extremes in the Arctic Ocean
Isabela S. Cabral, Ian R. Young, Alessandro Toffoli
Over recent decades, the Arctic Ocean has experienced dramatic changes due to climate change. Retreating sea ice has opened up large areas of ocean, resulting in an enhanced wave c…
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…
Ship resistance when operating in floating ice floes: a combined CFD&DEM approach
Luofeng Huang, Jukka Tuhkuri, Bojan Igrec +5
Whilst climate change is transforming the Arctic into a navigable ocean where small ice floes are floating on the sea surface, the effect of such ice conditions on ship performance…
Drift of pancake ice floes in the winter Antarctic marginal ice zone during polar cyclones
Alberto Alberello, Luke Bennetts, Petra Heil +5
High temporal resolution in--situ measurements of pancake ice drift are presented, from a pair of buoys deployed on floes in the Antarctic marginal ice zone during the winter sea i…

Amin Chabchoub, Kento Mozumi, Norbert Hoffmann +7
Solitons and breathers are nonlinear modes that exist in a wide range of physical systems. They are fundamental solutions of a number of nonlinear wave evolution equations, includi…

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…
Spontaneous emergence of rogue waves in partially coherent waves: a quantitative experimental comparison between hydrodynamics and optics
Rebecca El Koussaifi, Alexey Tikan, Alessandro Toffoli +3
Rogue waves are extreme and rare fluctuations of the wave field that have been discussed in many physical systems. Their presence substantially influences the statistical propertie…
An experimental comparison of velocities underneath focussed breaking waves

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…
