Indian Ocean coral bleaching


16 January 2018 – Given the entire WIO is showing abnormally cool conditions, two cyclones have occurred by mid-January and both ENSO and IOD indicators are neutral, we expect little bleaching in 2018. Most likely southern locations in the WIO will not experience bleaching stress, but it may develop in more northern locations as the season develops..
