Oman Coral Record and IOD Dynamics by Nasrul Delas is a document available to read on EtoBox.
The study presents a 26-year coral record from the Gulf of Oman, revealing a significant regime shift in seawater δ18O values in 1999, indicating intensified upwelling in the Western Indian Ocean during the global-warming hiatus. Prior to this shift, the Indian Ocean Dipole (IOD) influenced sea surface temperature and seawater δ18O, but this signature disappeared post-1999 due to increased upwelling. The findings suggest that upwelling dynamics in the region became uncoupled from the IOD, likely driven by c
