Glob Chang Biol 2021 Apr 12. Epub 2021 Apr 12.

Marine and Coastal Resources Research Center (Upper Eastern Gulf of Thailand), 58/5 Moo 8 Songklong Bangpakong, chachoengsao, Thailand, 24130.

Shallow reefs are a major feature of coral assemblages in the Andaman Sea. At Phuket, Thailand sheltered reefs are dominated by massive corals, together with an increasing abundance of branching species during favourable growth conditions. The growth of coral on these reefs is moderated by long-term increases in sea temperature and relative sea level but fluctuating decadal/intradecadal climate processes of El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD), which modulate sea level and temperature, are the main drivers of coral cover.
