Historical Remotely Sensed Sea Surface Temperature Data for Prediction of Coral Bleaching Event in Kish Island, the Persian Gulf
The capability of Degree Heating Weeks index (DHWs) was examined for prediction of bleaching events in the coral reef communities of the Kish Island located in the north of the Persian Gulf. In doing so, weekly Sea Surface Temperature (SST) values (in 1°×1° spatial resolution) prepared by National Oceanic and Atmospheric Administration (NOAA), coupled with documented bleaching events, such...
متن کاملSpecific Thermal Regime and Coral Bleaching Pattern in Hengam Island, the Eastern Persian Gulf
Thermal anomaly is among factors initiating coral bleaching and mortalities and threatening coral reefs worldwide. Therefore, susceptibility of corals to thermal stress is a central concern in reef conservation. In this study, we evaluated underwater temperature during 2012-13 and bleaching status of corals during summer 2012 in Hengam Island located in the eastern Persian Gulf. Hengam coral...
متن کاملPrediction of Bleaching in Coral Reef Communities Using a Temperature Index(Southern and northern Persian Gulf)
Sea surface temperature is one of the most effective physical parameters that affects the health of coral reefs communities.High frequency of the bleaching phenomenon has extensively occurred in the Persian Gulf in the recent years due to the increase in temperature and increased changes in the sea surface temperature (SST) resulting in great mortality in the coral communities. The aim of this ...
متن کاملestimating total economic value of coral reefs of kish island (persian gulf)
this paper is concerned with the economic valuation of the coral reef within kish island in persian gulf of iran. for calculating this value, all components of use and non-use values are estimated and then according to each of them, suitable method has applied. many different evaluation tools such as contingent valuation method, zonal travel cost method, replacement cost, avoided cost method, ...
متن کاملEffect of sea surface temperature (SST) changes on coral ecosystems in Kish Island
Background and Theoretical Foundations: Coral reefs are one of the world's most attractive ecosystems. They have been covering large parts of the world in the tropic areas. Coral reefs in the Iranian waters of the Persian Gulf are largely limited to the Islands. Many factors, including natural and anthropogenic activities cause stress to the reef communities affecting reef development. Coral bl...
