| Summary: | 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 layerin regions of melting [3], but are limited by uncertainty in thevalue of the friction coefficient and representations of the heatflux into the ice shelf and are wholly unsuitable when the natureof the ice-ocean interface is different [4], as a result of frazil formationin the super cooled waters. This paper will present anoverview of the commonly used parameterisations and highlightwhere uncertainties remain. |
