Modelling hydroelastic flexure of arbitrarily shaped ice shelves forced by long ocean waves
T. K. Papathanasiou, L. G. Bennetts, M. H. Meylan
Flexure of Antarctic ice shelves under excitation from long ocean waves induces mechanical ice shelf stresses that amplify fractures and, hence, contribute to calving events. Here,…
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…
Modelling dynamic strains on ice shelves resulting from flexural and extensional motions forced by ocean wave packets
Luke G. Bennetts, Jie Liang
The transient response of an ice shelf to an incident wave packet from the open ocean is studied with a model that allows for extensional waves in the ice shelf, in addition to the…
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…
Waves in ice
Luke G Bennetts
Ocean surface waves can propagate long distances through regions containing floating ice covers. The impacts ocean waves have on the ice covers are of interest in the climate chang…
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…

Jordan P. A Pitt, Luke G. Bennetts
A theoretical model is used to study water waves propagating into and through a region containing thin floating ice, for ice covers transitioning from consolidated (large floe size…
A thin plate approximation for ocean wave interactions with an ice shelf
Luke G Bennetts, Timothy D Williams, Richard Porter
A variational principle is proposed to derive the governing equations for the problem of ocean wave interactions with a floating ice shelf, where the ice shelf is modelled by the f…
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…
RayleighBloch waves above the cut-off
Luke G. Bennetts, Malte A. Peter
Extensions of Rayleigh-Bloch waves above the cut-off frequency are studied via the discrete spectrum of a transfer operator for a generalised channel containing a single cylinder.…
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…
Swell induced vibrations of a thickening ice shelf over a shoaling seabed
Michael Meylan, Muhammad Ilyas, Bishnu Lamichhane +1
A solution method is developed for a model of ice shelf vibrations in response to ocean waves, in which the ice shelf thickness and seabed beneath the ice shelf vary over distance,…
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,…
Broadband control of water wave energy amplification in chirped arrays
Aidan J. Archer, Hugh A. Wolgamot, Jana Orszaghova +3
Water waves in natural environments are typically broadband, nonlinear and dynamic phenomena. Taking concepts developed for slow light in optics, we address the challenge of design…
