我们调查了1993 - 2011年期间在印度尼西亚的海平面上升，使用卫星测高和验潮数据。卫星测高表明海平面正上升，平均为4毫米/年，高于全球平均海平面上升。在4个验潮站，验潮站与卫星共站测高所得的海平面变化趋势差异大于3 mm/yr。雅加达、泗水和贝诺瓦都有地面沉降现象。在Enggano和丹戎Lesung，2007年至2009年的垂直速率与GPS导出的速率一致，表明第一个站点发生了地面沉降。
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.
