Wave characteristics in the sea around the Andaman & Nicobar Islands

219-220Wave data were collected during 51 and 52 cruises (Feb. 1979) and 66 and 67 cruises (Jan. 1980) of R.V. Gaveshani using a shipborne wave recorder. Some wave records were also obtained along the 5°30'N lat. from Ceylon to the Great Nicobar Island during the 51 and 66 cruises. Scatter diagrams relating zero crossing period and significant wave height were prepared. Distribution of zero crossing period significant wave heights varied from 6 to 12 sec and 0.6 to 1.4 m around the Andaman and Nicobar Islands while along the equatorial transect they were respectively 7 to 9 sec and 0.8 to 1.8 m
