Abstract
Models of the circulation beneath ice shelves draw on knowledge
gained from observations of the turbulent boundary layer
beneath sea ice [1] to parameterise the thermodynamic interaction
between ice-shelf and ocean [2]. These parameterisations
are commonly transferred to the sub-ice-shelf boundary layer
in regions of melting [3], but are limited by uncertainty in the
value of the friction coefficient and representations of the heat
flux into the ice shelf and are wholly unsuitable when the nature
of the ice-ocean interface is different [4], as a result of frazil formation
in the super cooled waters. This paper will present an
overview of the commonly used parameterisations and highlight
where uncertainties remain.
