Role of breakage, melt and floe size distribution on sea ice summer transition ...
Marginal ice zones are composed of individual sea ice floes, whose breakage and melt shape summer behavior of the pack. These processes are generally not resolved by global or regional models, due to the continuum approximations used for sea ice. Here, we leverage a Discrete Element Model to investi...
