CONSTRAINING OCEANIC CIRCULATION AND BASAL MELTING RATES BENEATH ICE SHELVES (F6E21111)

Initial experiments indicate that large-scale topographic features drive dramatic changes in meridional boundary currents (which supply the vast majority of melt-producing water). Current experiments add additional isopycnal layers, illuminating the role of top and bottom boundary layers in the mass...
