A hybrid ice-mélange model based on particle and continuum methods [PDF]
The CryosphereIce mélange, a composite of sea ice and icebergs, can have a major influence on sea-ice–ocean interactions. However, ice mélange has not been represented in climate models because numerically efficient realizations do not exist.
