The Bismarck Sea (German: Bismarcksee) lies in the southwestern Pacific Ocean within the nation of Papua New Guinea. It is located northeast of the island of New Guinea and south of the Bismarck Archipelago and the Admiralty Islands. It has coastlines in districts of the Islands Region, Momase Region, and Papua Region.
Bismarck Sea in Papua New Guinea
|Etymology||Otto von Bismarck|
|Part of||Pacific Ocean|
|Basin countries||Papua New Guinea|
Like the Bismarck Archipelago, it is named in honour of the first 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 Southern Pacific Ocean. To the south it is linked to the Solomon Sea by the Vitiaz Strait.
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).
On the Southeast. A line from the Southern point of New Ireland along the parallel of 4°50' South to the coast of New Britain, along its Northern coast and thence a line from its Western extreme through the Northern point of Umboi Island to Teliata Point, New Guinea ( )
On the Southwest. By the Northeast coast of New Guinea.
Recent explorations in the Bismarck Sea seabed have yielded discoveries of mineral-rich beds of sulfides, copper, zinc, silver and gold. These findings are especially important because they lie in shallow, calm waters. Papua New Guinea owns the mining rights to these minerals under international law.
Aiyo Maru was a 2,746-ton transport ship of the Imperial Japanese Army during World War II.
She left Rabaul, New Britain on 1 March 1943, as part of Operation 81, carrying a cargo of 252 troops, equipment, fuel, landing craft and ammunition for Lae, New Guinea. The convoy was attacked by aircraft of the United States Army Air Forces and Royal Australian Air Force from 2 March 1943, known as the Battle of the Bismarck Sea. Aiyo Maru was bombed on 3 March and sank at 07°15'S., 148°30'E. Up to 323 soldiers and sailors were killed.Battle of the Bismarck Sea
The Battle of the Bismarck Sea (2–4 March 1943) took place in the South West Pacific Area (SWPA) during World War II when aircraft of the U.S. Fifth Air Force and the Royal Australian Air Force (RAAF) attacked a Japanese convoy carrying troops to Lae, New Guinea. Most of the Japanese task force was destroyed, and Japanese troop losses were heavy.
The Japanese convoy was a result of a Japanese Imperial General Headquarters decision in December 1942 to reinforce their position in the South West Pacific. A plan was devised to move some 6,900 troops from Rabaul directly to Lae. The plan was understood to be risky, because Allied air power in the area was strong, but it was decided to proceed because otherwise the troops would have to be landed a considerable distance away and march through inhospitable swamp, mountain and jungle terrain without roads before reaching their destination. On 28 February 1943, the convoy – comprising eight destroyers and eight troop transports with an escort of approximately 100 fighter aircraft – set out from Simpson Harbour in Rabaul.
The Allies had detected preparations for the convoy, and naval codebreakers in Melbourne (FRUMEL) and Washington, D.C., had decrypted and translated messages indicating the convoy’s intended destination and date of arrival. The Allied Air Forces had developed new techniques they hoped would improve the chances of successful air attack on ships. They detected and shadowed the convoy, which came under sustained air attack on 2–3 March 1943. Follow-up attacks by PT boats and aircraft were made on 4 March. All eight transports and four of the escorting destroyers were sunk. Of 6,900 troops who were badly needed in New Guinea, only about 1,200 made it to Lae. Another 2,700 were rescued by destroyers and submarines and returned to Rabaul. The Japanese made no further attempts to reinforce Lae by ship, greatly hindering their ultimately unsuccessful efforts to stop Allied offensives in New Guinea.Bismarck Archipelago
The Bismarck Archipelago is a group of islands off the northeastern coast of New Guinea in the western Pacific Ocean and is part of the Islands Region of Papua New Guinea. Its area is about 50,000 square km.Japanese destroyer Asashio (1936)

They served as first-line destroyers through the 1930s, and remained formidable weapons systems well into the Pacific War.Japanese minelayer Okinoshima
Okinoshima (沖島) was a large minelayer of the Imperial Japanese Navy, which was in service during the early stages of World War II. She was named after the Okinoshima Island in the Sea of Japan and the earlier Japanese battleship Okinoshima. She was the largest purpose-built minelayer of the Imperial Japanese Navy and the first Japanese minelayer to be equipped with a reconnaissance seaplane.Japanese transport Kembu Maru
Kembu Maru was a 953-ton transport ship of Imperial Japanese Army during World War II.
She left Rabaul, New Britain on 1 March 1943, as part of Operation 81, carrying a cargo of 1,000 drums of avgas and 650 drums of other fuel for Lae, New Guinea. The convoy was attacked by aircraft of the United States Army Air Forces and Royal Australian Air Force from 2 March 1943, known as the Battle of the Bismarck Sea. Kembu Maru was bombed on 3 March; she exploded in a giant fireball and sank at 07°15'S., 148°30'E.
20 troops are KIA.Karkar Island
Karkar Island is an oval-shaped volcanic island located in the Bismarck Sea, about 30 kilometres off the north coast of mainland Papua New Guinea in Madang Province. The island is about 25 km in length and 19 km in width. In the centre is an active volcano with two nested calderas.
The land is covered with the volcanic andesitic lava. The soil is very fertile and used for growing food crop and cash crop. The island is full of betel-nut, mustard plant and lime. The island is also known for the view from the mountain looking down to Madang town.
The latest eruptions on this island occurred in the 1970s. The 1974-1975 eruption produced a large volume of lava which covered almost 70 percent of the inner caldera's floor, while 1979 produced no lava flow, but killed the two volcanologists, Robin Cooke and Elias Ravian. The volcano erupted as recently as February 26, 2013.The population of approximately 70,000 is mostly Lutheran and Catholic and speaks the two languages Waskia and Takia. Most people also speak Tok Pisin, and English is taught in the schools. Neighboring islands are Bagabag (Papua New Guinea) and Manam.
A single road runs around the entire length of the island. Karkar Secondary School is the only high school. There is one hospital, Gaubin Hospital, known formally as the Edwin & Tabitha Tscharke Memorial Hospital, which is run by the Lutheran Health Service and staffed by several rotating German doctors. The hospital includes a training center for Community Health Workers.
The two main exports from the island are cacao and coconuts, which can grow in the same soil due to vast height differences. Large plantations are generally family owned.Manam Motu
Manam, known locally as Manam Motu, is an island located in the Bismarck Sea across the Stephan Strait from Yawar on the northeast coast of mainland Papua New Guinea's Bogia District.

It was evacuated in 2004 and its residents resettled elsewhere in Papua New Guinea, but many have begun to return despite concerns of future volcanic activity.North Bismarck Plate
