ABSTRACT :

CSIR-National Institute of Oceanography, Goa has established an Integrated Coastal Observation Network (ICON) of in-house designed and developed Internet-accessible near real-time reporting cellular based sea-level, sea-state and surface meteorological (Met) stations at several locations on the coast of India, including the Islands (http://inet.nio.org). The voluminous data generated have been used to examine the storm-generated sea level variation in the Arabian Sea and Bay of Bengal. Specifically, ICON has enabled to analyse the impacts of tropical cyclones (such as Yemyin, Phyan and Thane) and geophysical tsunami (2004, 2007) on coastal sea level. The sea level and surface meteorological measurements collected during these extreme events exhibit storm surge up to ~43 cm on the west coast and ~29 cm on the east coast of India. The tropical cyclone "Phailin" (9-12 October 2013) generated surges upto 70 cm and 52 cm at Gangavaram and Kakinada, respectively. However, at Port Blair, the surge depressed to ~16 cm. Results of the above studies indicate the importance of having extended concurrent measurements of surface atmospheric parameters along with sea level. This internet-based near-real time monitoring provides considerable information to disaster managers and local administrators during episodic events.
