GPS, absolute gravity and GRACE satellite data have been combined to map postglacial rebound (glacial isostatic adjustment) and to identify large spatial-scale water storage variations in the Nelson River drainage basin. GPS data from 27 continuous sites over the period 1996-2010 with an average time-series length of 10.6 years were combined with data from over 50 regularlysurveyed monuments over the period 1995-2011 to produce an updated vertical velocity map for the basin.
