                     from 1976 to 1996. MBT(1633 stations), CTD(1679 stations),     
                     XBT(777 stations), HYDRO-CAST(2762 stations) and   
                     CHEMISTRY(2419 stations) are available.
2. Levitus Data   :  Hydrographic data selected from World ocean database   
                     1998 CD for the Indian ocean. Since the database size is   
                     too large, we split it into two. DB Tables namely, North

                     (0 to -30 Lat.). HYDRO-CAST and CHEMISTRY data (16021 stations)
