Two Sanctuaries are currently designated by the International Whaling Commission, both of which prohibit commercial whaling. The first of these, the Indian Ocean Sanctuary, was established in 1979 and covers the whole of the Indian Ocean south to 55°S.
The second was adopted in 1994 and covers the waters of the Southern Ocean around Antarctica. The boundaries of both of the Sanctuaries can be seen on this map and their precise co-ordinates are recorded in the Schedule at paragraphs 7.(a) and 7.(b)
An additional proposal for a Sanctuary in the South Atlantic Ocean has been repeatedly submitted to the Commission in recent years. To date it has failed to achieve the three-quarters majority of votes needed to amend the Schedule and thus become designated by the IWC.
