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…
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…
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…
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…
Hydroelastic interactions between water waves and floating freshwater ice
Azam Dolatshah, Filippo Nelli, Luke G. Bennetts +4
Hydroelastic interactions between regular water waves and floating freshwater ice are investigated using laboratory experiments for a range of incident wave periods and steepnesses…
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…
An idealised experimental model of ocean surface wave transmission by an ice floe
Luke Bennetts, Alberto Alberello, Michael Meylan +3
An experimental model of transmission of ocean waves by an ice floe is presented. Thin plastic plates with different material properties and thicknesses are used to model the floe.…
