DESCRIPTION:Sea ice is a granular material composed of interacting element
 s\, called floes\, of different and evolving sizes and shapes. Contemporar
 y numerical models of sea ice\, although incorporating aspects of granular
  material dynamics\, do not realistically represent the evolution of floe 
 size distribution\, which is affected by and upon which depend a myriad of
  dynamical and thermodynamical processes. Although this problem is theoret
 ically\, numerically and experimentally challenging\, there has been signi
 ficant progress over the past decade thanks to many international collabor
 ative efforts\, especially through revisiting marginal ice zone dynamics w
 here surface gravity waves exert a strong control on floe size. This prese
 ntation will provide an overview of the theoretical and experimental knowl
 edge on sea ice break-up and floe size distribution and will discuss how t
 his topic is handled analytically in models.
