A laboratory study of melting vertical ice sheets
immersed in sodium chloride solutions of oceanic
temperatures and salinities found that the convective
motions generated by the melting consist of two regions
confined to a boundary layer adjacent to the ice. The
first region, at the bottom of the ice, is laminar and
bidirectional, with a 2 to 3 mm thick upward flowing
layer next to the ice inside of a 10 mm thick outer
downward flowing layer. This bidirectionality results
from the large difference between the thermal and saline
diffusivities which contain dilute water near the ice and
allows the cooling to diffuse further from the ice. Near
the ice, dilute cold water rises; while away from the
ice, cold saline water sinks. Second, further up the ice,
the inner layer goes through a region of transition and
becomes fully turbulent when the saline Grashof number
reaches 2 x 10 to the 8th power. The turubulent flow is
upward, unidirectional and the dominant flow in the
oceans.
