Predictions of heat stress at the outer reef site and day-to-day temperature variabilty. (a) Time series of temperature for the pixel encapsulating Mascherchur reef for the 2017 and 2018 marine heatwaves, and in situ temperatures for the 2018 heatwave (shown as the mean across the three loggers at this reef). Dashed lines show the heat stress accumulation threshold (maximum of monthly means – MMM + 1 °C for CoralTemp, and the adjusted MMM + 1 °C for both MUR and in situ data). (b) Time series of accumulated heat stress, with close match between CoralTemp and in situ data. (c) Distributions of day-to-day changes in temperature, showing the min to max range (fine feather), the 95% range (2.5th percentile to 97.5th percentile, medium feather), the interquartile range (bold feather), and the mean (point). (d) Frequency of days with temperatures exceeding different levels relative to the dataset-specific MMM, showing a higher frequency of hot days for the MUR dataset.
