Article on Coastal morphology and sea-level changes in Goa

Nils-Axel Mörner, Professor Emeritus and former head of the Paleogeophysics and Geodynamics department at Stockholm University, recently published an article entitled: "Coastal morphology and sea-level changes in Goa, India during the last 500 years" in Journal of Coastal Research, 33:2, 421-434.

Abstract: Coastal morphology, stratigraphy, radiocarbon dating, archaeological remains, historical documentation, and tide gauge records allowed us to establish a very firm and detailed record of the changes in sea level in Goa over the last 500 years. It is an oscillation record: a low level in the early 16th century, a +50-cm high level in the 17th century, a level below present sea level in the 18th century, a +20-cm high level in the 19th and early 20th centuries, a ∼20-cm fall in 1955–1962, and a virtually stable level over the last 50 years. This sea level record is almost identical to those obtained in the Maldives and in Bangladesh. The Indian Ocean seems to lack records of any alarming sea-level rise in recent decades; on the contrary, 10 sites analyzed indicate a sea level remaining at about ±0.0, at least over the last 50 years or so.
