“…The Multi-channel Sea Surface Temperature (MCSST) data from NOAA Advanced Very High Resolution Radiometer (AVHRR) was used for assess the thermal stress on coral reef around the Andaman reef environs during 28 March to 30th Apr2016. The calculation of thermal stress on coral reef [8,18] using bi-weekly composite AVHRR SST data was carried out (Figure 1). In the present study the monthly climatology was extracted using daily long term time series AVHRR SST data from 1985 to 2016.…”

Abstract:Coral bleaching reported in the North Bay, Andaman Islands during the April last week of 2016 due to thermal stress. The Coral Bleaching Alert System (CBAS) a service providing by Indian National Centre for Ocean Information Services (INCOIS) has reported the warning and the bleaching has been confirmed from the field survey conducted on April 26, 2016. As coral reef is important fragile eco-system of the shallow marine environment suffers due to human and natural impacts. Bleaching has been initiated as weather predictions of the various agencies have suggested the elevated temperatures in the Indian subcontinent this year. We have put forward our remote sensing analysis of coral bleaching warning as Alert Level-1 followed by the initiation of the coral bleaching in the in-situ observation at Andaman Islands enhances the credibility of satellite observation and the service of INCOIS. These results were useful for the coastal management authority for taking suitable measure and policy on important coral eco-system.

“…NOAA AVHRR Sea Surface Temperature (SST) data were used to identify cumulative temperature anomalies and thermal stress over coral reef regions. These two products were used to identify probable areas of bleaching (Mohanty et al 2013). It was observed that soft corals such as Acropora are affected significantly, unlike hard corals such as Porites.…”

The coastal zone is a region where land, ocean and atmosphere interact and hence it is dynamic in nature. India has a long coastline which was not adequately monitored until the advent of the satellite remote sensing era in the 70s. India has a very robust remote sensing program that the Indian Remote Sensing Satellite (IRS) series of satellites were effectively used to monitor coastal habitats, landforms, shoreline, water quality, etc., and changes were identified during the last 40 years. The classification system for coastal habitats and the classification and geometric accuracies of products were standardized. Detailed information for mangroves communities and characteristics of coral reefs were generated. The high and low tide lines were delineated seamlessly for the entire coastline using satellite data. All these data were organized in a GIS and the coastal database for the entire country was created. Impacts of various hazards on such as cyclones, tsunami and sea level changes on coastal habitats were documented. Based on topography, shoreline changes and tides, coastal multi-hazard vulnerability maps were characterized by employing the elevation data derived from satellite data and were prepared for the coastline of India. The information on ocean color and sea surface temperature was used to generate potential fishery advisories, which are provided daily to fishermen. The coastal database was utilized effectively to identify coastal regulation zones, marine protected areas, vulnerable zones, etc. Various services for tsunami, fishery and coral reef bleaching were generated for societal benefits. It is planned to develop models for the coastal zone, so that impeding dangers and likely changes in the coastal zone can be predicted and suitable actions can be undertaken. It is necessary to integrate socioeconomic data with the knowledge database of coastal zone to understand the impact of anthropogenic activities and the changing climate on the coastal zone.
