We investigate the sea level rise in Indonesia during the period 19932011 using satellite altimetry and tide gauge data. Satellite altimetry indicates a positive sea level rise with mean of 4 mm/yr, which is higher than the global averaged mean sea level rise. At four tide-gauge stations the difference of the sea level trends from tide gauge and co-located satellite altimetry is greater than 3 mm/yr. Land subsidence is found in Jakarta, Surabaya and Benoa. At Enggano and Tanjung Lesung the vertical rates correspond with GPS-derived rates between 2007 and 2009, indicating land subsidence at the first station.
