This thesis aimed at this hotspot, also one of the important regions during the Ninth-and Tenth-Five-Year-Program periods of Chinese Antarctic research. It made use of Radio Echo-Sounding data, surface horizontal ice flow velocity data, digital elevation model data, surface mass accumulation data and the data concerning melting at the bottom of Amery Ice Shelf , to study the grounding line, mass balance, and ice kinematic characteristics of grounded ice sheet and floating ice shelf respectively.

The result reveals that the modal values of iceberg length in Ross Sea and Weddell Sea are 880m and 1180m respectively; iceberg drifts here are mainly north-eastward or north-westward and drift velocities are similar to those of Arctic iceberg. And the max-iceberg length in Prydz Bay increases and then decreases as closing Amery Ice Shelf in the latitude range of 65.4°S~68.2°S, which accords with the mechanics rule of object falling.
