Bismarck Sea

The Bismarck Sea lies in the southwestern Pacific Ocean to the north of the island of Papua New Guinea and to the south of the Bismarck Archipelago and Admiralty Islands. Like the Bismarck archipelago, it is named in honour of the German chancellor Otto von Bismarck. The Bismarck archipelago extends round to the east and north of the sea, enclosing the Bismarck Sea and separating it from the Pacific Ocean. To the south it is linked to the Solomon Sea by the Vitiaz Strait.

It was the site of a major Japanese naval defeat in the Battle of the Bismarck Sea during World War II on 3 and 4 March 1943.

Extent

The International Hydrographic Organization defines the Bismarck Sea as "that area of the South Pacific Ocean off the Northeast coast of New Guinea", with the following limits:

On the North and East. By the Northern and Northeastern coasts of the islands of New Ireland, New Hanover, the Admiralty Islands, Hermit Island, and the Ninigo Group, through Manu and Aua Islands to Wuvulu Island and thence a line to Baudissin Point in New Guinea (142°02'E).
