This post by Jim Steele shows how corals are affected by El Nino events when the trade winds slacken that bring weather to the north Queensland region and Barrier Reef.

[…] Indeed the Great Barrier Reef had also experienced falling sea levels similar to those experienced by Indonesian reefs. Visitors to Lizard Island had reported more extreme low tides and more exposed reefs as revealed in the photograph above, which is consistent with the extremely high mortality in the Lizard Island region during the 2016 El Niño. Of course reefs are often exposed to the air at low tide, but manage to survive if the exposure is short or during the night. However as seen in tide gauge data from Cairns just south of Lizard Island, since 2010 the average low tide had dropped by ~10 to 15 cm.
That’s how I saw things here in Broome 15 years ago. The Gulf of Carpentaria’s dead mangroves may have been another ‘low tide event’. From a comment by Professor Ridd:
