The Institute collected detailed baseline data of entire reef areas in Gulf of Mannar (GOM) during 2003-2005. The status of corals is GOM was 37% in 2005, which increased to 39% in 2015, but in 2016 climate change caused bleaching due to the severe 3rd global bleaching event resulted in 16% coral mortality and reduced the coral status to 23%.
