Table 1.
Temperature conditions during the high temperature anomaly in 2010 summarized for the exposed west (W) and sheltered east (E) sites; Tachai W (TW), Payang W (PW), Miang W (MW), Similan W (SiW), Racha W (RW), Surin W (SuW), Bon W (BW), Racha E (RE), Payang E (PE), Miang E (ME), Similan E (SiE) and Surin E (SuE). Temperature values include mean, maximum (max) and minimum (min) temperature recorded during this period. LAIW cooling intensities are calculated as degree-day cooling (DDC) below the NOAA bleaching threshold (30.62°C). Degree heating weeks (DHW) derived from satellite (DHWs) and field data (DHWf) reflect differences in heat anomaly observed at the sea surface and in 15 m water depth.

aPayang E, Payang W, Similan E and Similan W data are unavailable. For calculation of DHWf, temperature data were taken from corresponding E and W sites of Miang, respectively. For justification cf. Schmidt et al. [15].
bRacha E temperature record was available only for 20 and 10 m water depth. Values for 15 m water depth were obtained by linear interpolation.
