[00:00:11]About the Bismarck Sea. The Bismarck Sea is located in the southwestern Pacific Ocean. It is bordered by the northeast coast of Papua New Guinea to the southwest. The Bismarck Archipelago, including the Admiralty Islands, New Ireland, and New Britain, forms its northwestern to southeastern boundary.

[00:00:30]The sea connects to the Pacific Ocean in the north and the Solomon Sea in the southeast via the Vitiaz and Dampier Straits and St. George's Channel. The basin has an average depth of 2,000 m, with maximum depths reaching approximately 2,500 m. A central ridge divides the sea into eastern New Ireland and western New Guinea sections. The sea was under German control from 1885 to 1914 and is named after German statesman Otto von Bismarck. It was a significant location for naval battles between Allied forces and Japanese troops during World War II. The Battle of the Bismarck Sea in March 1943 was a key engagement where Allied forces intercepted a Japanese convoy. Today, historians and divers explore the area searching for submerged vessels and aircraft.
