Controls of the basal mass balance of floating ice shelves

Models of the circulation beneath ice shelves draw on knowledgegained from observations of the turbulent boundary layerbeneath sea ice [1] to parameterise the thermodynamic interactionbetween ice-shelf and ocean [2]. These parameterisationsare commonly transferred to the sub-ice-shelf boundary layer...
