Abstract

Presently climate change is a serious problem on corals and their associated ecosystems that also affects the national and international income. The Present study emphasizes the impact of sea surface temperature on coral living, coral bleaching, coral growth and modelling for influential high temperature on corals as a significant biodiversity of tropical regions. Coral bleaching information, data of Sea Surface Temperature (SST), and coast watch utility software collected from the National Oceanic and Atmospheric Administration (NOAA) is an important way of monitoring and modelling of coral responses to SST. These data represent that the higher range of sea surface temperature and anomaly is responsible for the greater change of the coral bleaching area and hotspot. Within the narrow sea surface temperature change coral can respond significantly. This model finds southern pacific is most vulnerable and attractive sites for coral bleaching. Eastern tropical Pacific and Caribbean coral has been affected by El Nino and the anomaly of sea surface temperature. We need to continue to develop the models for protecting the coral reefs to present natural and anthropogenic climate change induced sea surface temperature causing the coral bleaching events.
