Project Locations
East Antarctica (Dronning Maud Land)
Project Activities
Repeated absolute gravity measurements and continuous/campaign GNSS-measurements in Dronning Maud Land. Auxiliary measurements to correct gravity for variation in attraction of local glacier mass. GRACE evaluation.
Principal Science Objectives
Measurement of crustal motion and surface gravity change. Their joint interpretation together with GRACE and satellite radar/laser altimetry to determine glacial isostatic adjustment and variation in contemporary ice mass load.
Research Highlights
Vertical motion and gravity change in Dronning Maud Land constrained. First CGPS site in western Dronning Maud Land. We have done three out of the seven Antarctic absolute-gravity sites that have repeated observations. Aboa is the first absolute-gravity site where local glacier attraction is systematically monitored.
