Data for: Continuous simulations over the last 40 million years with a coupled Antarctic ice sheet-sediment model
Description
Netcdf files of coupled Antarctic ice sheet-sediment simulations over the last 40 Myr. A polar stereographic projection is used, centered on South Pole. Spatial fields of selected mode variables are saved every 100,000 years. fort.92_sedi23_seltime.nc is the main non-iterative simulation described in the paper (sections 3-5, horizontal resolution = 80 km). fort.92_sedi25_seltime.nc is the main iterative simulation in the paper (sections 6-7, last iteration, horizontal resolution = 160 km). The main 2-D model fields in the Netcdf files are: alatd (latitudes at grid centers) alond (longitudes at grid centers) h (ice thickness, m) hs (surface elevation above sea level, m) hb (bed elevation including sediment, m) hw (thickness of ocean water column) topbed (hard bedrock elevation below sediment, m) maskwater (0 is grounded ice or land, 1 if floating ice or open ocean) quarryacc (total bedrock eroded since start of simulation , m) sedim (sediment thickness, m)
