Fig. 3: Water mass properties in the deep-ice region in the WARM forcing experiments.
From: Channelized topography amplifies melt-sensitivity of cold Antarctic ice shelves
a Temperature-salinity diagram, showing water properties of modified Circumpolar Deep Water (mCDW) and Winter Water (WW) in the deep-ice region, with dark (light) blue indicating water located at the bottom (surface). The pink dashed line indicates the CDW-WW mixing line, and the black dashed line marks the surface freezing point referenced by surface pressure. Isopycnals are shown as gray curved lines. The green (yellow) solid line represents the meltwater-mixing line of mCDW (WW). The two green (yellow) dots along this line mark the transformation from source water (upper dot) to the meltwater-modified version, mCDW ́ (WW)́ (lower dot), due to ice-ocean interaction. The inset shows water mass properties in the deep-ice region relative to the full domain (light grey points). Spatial distributions of reference salinity at the ice-ocean interface in the SMOOTH (b) and ROUGH (c) draft experiments, with blue (yellow) color indicating mCDW (WW) sourced water and gray contours showing the ice draft at 50 m intervals.
