In seasonally ice-covered seas and along the margins of perennial ice pack, i.e., in regions with medium ice concentrations, the ice cover typically consists of separate floes interacting with each other by inelastic collisions. In this paper, hitherto unexplored analogies between this type of ice cover and two-dimensional granular gases are used to formulate a model of ice dynamics at the floe level. The model consists of (i) momentum equations for floe motion between collisions, formulated in… 
Influence of ice concentration and floe-size distribution on cluster formation in sea-ice floes
At medium ice concentrations, sea ice consists of separate floes of different sizes interacting with each other through inelastic collisions, in a way similar to two-dimensional polydisperse granular
Numerical modeling of force and contact networks in fragmented sea ice
Abstract In this paper, a molecular-dynamics sea-ice model is used to study contact and force networks in fragmented sea ice, composed of separate floes with power-law size distribution. The momentum
The evolution of scaling laws in the sea ice floe size distribution
The sub-gridscale floe size and thickness distribution (FSTD) is an emerging climate variable, playing a leading-order role in the coupling between sea ice, the ocean, and the atmosphere. The FSTD,
Modélisation dynamique d'un assemblage de floes rigides. (Dynamics of an assembly of rigid ice floes)
TLDR
A model describing the dynamics of a population of ice floes with arbitrary shapes and sizes, which are exposed to atmospheric and oceanic skin drag is presented, and it is suggested that collisional regimes of floe dispersion at small scales are different from a large-scale regime essentially driven by wind forcing.
A prognostic model of the sea-ice floe size and thickness distribution
Abstract. Sea ice exhibits considerable seasonal and longer-term variations in extent, concentration, thickness, and age, and is characterized by a complex and continuously changing distribution of
Sizes and Shapes of Sea Ice Floes Broken by Waves–A Case Study From the East Antarctic Coast
The floe size distribution (FSD) is an important characteristics of sea ice, influencing several physical processes that take place in the oceanic and atmospheric boundary layers under/over sea ice,
Characterizing the size and shape of sea ice floes
TLDR
The size and the elongation of ice floes (floating pieces of ice) are measured using satellite images of sea ice from four different locations in both the northern and southern hemispheres and it is found that floe size follows a distribution that can be characterized with good approximation by a single length scale.
Sea Ice Deformation
Instead of individual trajectories, this chapter consider velocity gradients within sea ice, i.e. deformation rates. This can be done either from the analysis of the relative dispersion of tracers
Estimating The Sea Ice Floe Size Distribution Using Satellite Altimetry: Theory, Climatology, and Model Comparison
Abstract. In sea-ice-covered areas, the sea ice floe size distribution (FSD) plays an important role in many processes affecting the coupled sea-ice-ocean-atmosphere system. Observations of the FSD
Pancake sea ice kinematics and dynamics using shipboard stereo video
Abstract In the marginal ice zone, surface waves drive motion of sea ice floes. The motion of floes relative to each other can cause periodic collisions, and drives the formation of pancake sea ice.
