| Outline of Final Research Achievements |
Large changes are observed in polar cryosphere and ocean along with the recent climate change/global warming. The purpose of this project is to investigate Antarctic ice shelf/sea ice/ocean interactions, using a coupled ice shelf-sea ice-ocean model. We performed simulations for present and Last Glacial Maximum conditions, and a simulation with fine resolution over the Adelie Land region, East Antarctica. From the above numerical simulations, we found that sea ice production in Antarctic coastal regions and intrusion of Circumpolar Deep Water from shelf break are important factors for basal melting of Antarctic ice shelves.
