  1. Bell ICEBRDIGE Science Update - Gravity Bathymetry &Water • Links with Bathymetry or Radar Improve Results • Regional Geologic Constraints Improve Results • Low, Slow, Straight Optimal Operation Mode • WATER…. • Considering How Basal Hydrology Works

  2. Bell ICEBRDIGE Science Update - Gravity Bathymetry & Water • Morphology Beneath Ice Shelves – (Cochran and Bell) • Larsen C • Approach Grid Survey (5-10 km ideal), Inversion of grid • Constraining Sills • Thwaites (Tinto et al), PIG (Studinger et al), Petermann (Tinto et al) • Along Flow Profiles (5-10 km ideal), Analysis along profile • Estimating Basal Conditions – soft/hard bed • Jakobshaven (Block and Bell) • Flow Perpendicular Profiles, Requires good bed topography &coincident surface elevation • Fjord Geometry • Jakobshaven (Block and Bell) • Sensitive to Sediment Fill – Requires Bathymetry or Grounded Ice Thickness • NW Greenland (Tinto et al -) • Fjord Perpendicular Profiles) • Links with Bathymetry or Radar Improve Results • Regional Geologic Constraints Improve Results • Low, Slow, Straight Optimal Operation Mode • WATER…. • Considering How Basal Hydrology Works
