报告内容：Antarctic ice sheet (AIS), as an important component of the earth system, plays a unique role in global climate change studies. We have conducted a comprehensive study on the AIS mass change and associated global sea level rise based on historical data, recent satellite data and field measurements, extending the timeline back to 1960s.

The following research results will be presented:

1)     We have systematically evaluated the major remote sensing products of Antarctic coastline, grounding line and DEMs, and then used the results to estimate the changes in AIS over the period from 1963 to 2015.

2)     Three methods, including input-output, altimetry and gravimetry, have been used to estimate the Antarctic mass balance. A precision regional estimation method was developed for change monitoring in the Lambert Glacier-Amery Ice Shelf System (LAS) where ground observations of CHINARE were employed.

3)     Results of Antarctic ice shelf changes will be presented. Specifically the fracturing and instability of Ronne-Filchner Ice Shelf were studied by utilizing multi-source satellite data (including Chinese ZY-3 optical stereo images).

4)     A glacier velocity map in East Antarctica was generated using ARGON/Landsat satellite images from 1960s to 1980s.

Finally, the contribution of AIS mass change to the global sea level change was evaluated. The relationship between the global and China coastal sea level changes was quantified.
