SUMMARY:Simulating Southern Ocean\, sea ice\, and ice shelf interactions: 
 model intercomparison and future projections - Kaitlin Naughten (British A
 ntarctic Survey)

DESCRIPTION:Antarctic ice shelf cavities are set to become a standard comp
 onent in ocean models\, with an increasing number of models considering th
 ermodynamics at the ice-shelf/ocean interface. The first part of this talk
  presents a model intercomparison and evaluation of present-day ocean/sea-
 ice/ice-shelf interactions as simulated by two models: MetROMS (ROMS: Regi
 onal Ocean Modelling System coupled to CICE: Community Ice CodE) and FESOM
  (Finite Element Sea-ice/Ice-shelf Ocean Model)\, where the latter is run 
 at two different levels of horizontal resolution. Simulated ice shelf basa
 l melting and sub-ice shelf circulation are analysed\, as well as sea ice 
 properties and Southern Ocean water mass characteristics as they influence
  the sub-ice shelf processes. The second part of this talk presents future
  projections of ice shelf melting in FESOM during the 21st century. The mo
 del is forced with bias-corrected atmospheric output from CMIP5 simulation
 s\, using two different future climate scenarios and two choices of CMIP5 
 models. The processes driving increased ice shelf melting in different sec
 tors of Antarctica\, as well as simulated changes in sea ice cover\, water
  mass properties\, and ACC transport\, are explored.
