Recent studies have shown that coral bleaching in the Cozumel area is diminished by as much as 15% from the year before.  According to officials in the  National Marine Park, only 10% of the corals studied in 2012 were affected by coral bleaching.  This is a significant improvement over 2011’s results, which indicated that 25% were affected.  These results are based on surveys which are conducted monthly.  Coral bleaching, is due in part, to high water temperatures, which , cause corals to expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.
