The Western limit of Coastal waters of Southeast Alaska and Br. Columbia, and the Southern limit of the Gulf of California. On the South.

South Pacific Ocean The 3rd edition, currently in force, of the International Hydrographic Organization's (IHO) Limits of Oceans and Seas defines the limits of the South Pacific Ocean (excluding the seas it contains) as follows: On the West. From Southeast Cape, the Southern point of Tasmania, down the meridian of 146°55'E to the Antarctic continent. On the Southwest and Northwest.
