Are sea-level-rise trends along the coasts of the north Indian Ocean consistent with global estimates?

Abstract

Mean-sea-level data from coastal tide gauges in the north Indian Ocean were used to show that low-frequency variability is consistent among the stations in the basin. Statistically significant trends obtained from records longer than 40 years yielded sea-level-rise estimates between 1.06–1.75 mm yr − 1 , with a regional average of 1.29 mm yr − 1 , when corrected for global isostatic adjustment (GIA) using model data. These estimates are consistent with the 1–2 mm yr − 1 global sea-level-rise estimates reported by the Intergovernmental Panel on Climate Change.
