The steady position of the grounding line, obtained from our SPH simulations, is in good agreement with laboratory observations for a wide range of bedrock slopes, ice-to-fluid density ratios, and flux.
Everywhere spread fields of heather, furze-covered pitches and barren bogs, sloping upwards to ice-gouged valleys.
The ice bustles had cylindrical shapes with slightly downward sloping side walls.
According to Liu et al. (2001), the vertical accuracy of the RAMP DEM ranges from ±7.5 m for the gently sloping interior of the ice sheet to ±100 m over rugged mountainous areas.
"Because the base of the ice shelf is sloping upwards, this water flows quickly up the bottom of the ice shelf, and as it does that, it mixes and stirs in the warm water from beneath," said Nicholls.
In the vicinity of Ross's inlet he found a spot where the ice sloped sufficiently to suggest that a landing was possible.
