The effects of rotation and ice shelf topography on frazil-laden ice shelf water plumes / Paul R. Holland, Daniel L. Feltham.

Title: The effects of rotation and ice shelf topography on frazil-laden ice shelf water plumes / Paul R. Holland, Daniel L. Feltham.
Author(s): Holland, Paul R.
Feltham, Daniel L.
Date: 2006.
In: Journal of Physical Oceanography. (2006.), Vol. 36(12) (2006)
Abstract: Presents model of dynamics and thermodynamics of plume of meltwater at base of ice shelf. Model incorporates both melting and freezing at ice shelf base and multiple-size-class model of frazil ice dynamics and deposition, as ice shelf water plumes may become supercooled and deposit marine ice if they rise due to pressure decrease in in situ freezing temperature. Plume is considered in two horizontal dimensions to incorporate influence of Coriolis forces. Rotation was extremely influential, with simulated plumes flowing in near-geostrophy due to low friction at smooth ice shelf base, such that ice shelf water plume will only rise and become supercooled if constrained to flow upslope by topography, a result which agrees with observed distribution of marine ice under Evans Ice Stream section of Filchner-Ronne Ice Shelf, Antarctica. Model only produces reasonable marine ice formation rates when accurate ice shelf draft is used, implying that characteristics of real ice shelf water plumes can only be captured using models with both rotation and realistic topography.
