a Difference between pre-FSC05 regulation and the NoShips scenario during February 2022, b difference between post-FSC05 regulation and the NoShips scenario during February 2022, c difference between post- and pre-FSC05 regulation conditions during February 2022 and d difference between post- and pre-FSC05 regulation conditions during 18–28 February 2023. Panels a–c highlight the accumulation of pollutant effects during the pre-bleaching period in 2022, while panel d highlights that if strong south-easterly trade winds dominate, pollutant effects are dissipated. Maps are annotated above with the mean absolute and percentage changes over the GBR and ocean regions. Location markers are the same as in Figure 1a.
