Beskrivning av projektet
Aim of this research is to deepen the knowledge of the cryosphere-lithosphere interaction in Antarctica and to improve current and future scenarios of the Antarctic Ice Sheet contribution in the global Sea Level Rise. Measure-ments of absolute gravity change, together with observed vertical deformation from GNSS (Global Navigation Satel-lite System), corrected for predicted gravity effects from nearby snow-field and glacier mass changes, measured with laser scanning (both UAV (Unmanned Aircraft Vehicle) and mobile mapping) and altimetry, analysed with the input-output method and measured gravity change from GRACE (Gravity Recovery and Climate Experiment), and compared with predicted gravity change and vertical motion from Glacial Isostatic Adjustment (GIA) models, will improve current GIA models and, therefore, also estimates for the Antarctic ice mass balance and predictions for Antarctic contribution to sea-level rise.
