Question: In which ocean is the island on which Busen Point is found ?

Context paragraphs:
Jumbo Cove: Jumbo Cove ( ) is a cove 0.5 nmi southeast of Busen Point on the north coast of South Georgia.  It was charted and named by Discovery Investigations personnel during the period 1926–30.

Busen Point: Busen Point or Busen Peninsula ( ) is a headland forming the southeast side of the entrance to Stromness Bay, on the north coast of South Georgia.  It lies on the Lewin Peninsula between Cumberland West Bay and Stromness Bay.

South Georgia Island: South Georgia is an island in the South Atlantic Ocean that is part of the British Overseas territory of South Georgia and the South Sandwich Islands.  The main settlement is Grytviken.  South Georgia is 167.4 km long and 1.4 to wide.  It is about 830 km north-east of Coronation Island and 550 km north-west from Zavodovski Island, the nearest South Sandwich island.

Ponquogue Parkway: In 1938, after the destruction to Fire Island from the Long Island Express hurricane, Robert Moses and W. Earle Andrews, both part of the Long Island State Park Commission, proposed reconstruction of the island.  This proposal included an extension of the Ocean Parkway out from its terminus at Captree State Park across Fire Island to Westhampton.  This new parkway, which would boast 22 ft wide roadways, would have connections back to the mainland at Smith Point County Park and Ponquogue with parkway spurs across Shinnecock Bay and the Great South Bay.  The new spur at Ponquogue, deemed the Ponquogue Parkway, would have marked the eastern terminus of the new Ocean Parkway extension.  The proposal lived until the cut-back to Smith Point County Park in 1962 for environmental issues with such a construction, ending any proposal for a parkway in the area of Hampton Bays.

Stromness Bay: Stromness Bay is a bay 3 mi wide, entered between Cape Saunders and Busen Point on the north coast of South Georgia.

Harrison Point: Harrison Point is a point marked by a string of off-lying rocks, lying 1.5 nmi west of Busen Point on the south side of Stromness Bay, South Georgia.  It was charted in 1927 by Discovery Investigations (DI) personnel and named "Matthews Point" for L. Harrison Matthews, a British zoologist and member of the DI staff, 1924–35, who worked at South Georgia in 1924–27.  In 1954, the UK Antarctic Place-Names Committee recommended that this name be altered to Harrison Point to avoid duplication with Matthews Point (also named for L. Harrison Matthews), a better known feature in Undine Harbour, South Georgia.  This change allows Matthews' name to be retained for this feature, while the confusing duplication of names is avoided.

Justa Peak: Justa Peak ( ) is a peak, 495 m high, lying southwest of Busen Point on the north coast of South Georgia.  The name appears to be first used on a 1929 British Admiralty chart.

Bucentaur Rock: Bucentaur Rock ( ) is the outermost of three rocks lying close northeast of Busen Point, at the southeast side of the entrance to Stromness Bay, South Georgia.  The name Low Rock was given for this feature during a survey in 1927, but this name is used elsewhere in the Antarctic.  Following the survey by the South Georgia Survey, 1951–52, the feature was renamed Bucentaur Rock after the floating factory "Bucentaur", which was anchored at Husvik in the early years of the whaling station after 1907, and from which the Husvik transport "Busen" and the catchers "Busen I", "II", "III", etc., derive their names.

Ems Rock: Ems Rock ( ) is a rock midway between Harrison Point and Busen Point in the south part of Stromness Bay, South Georgia.  It was charted by Discovery Investigations personnel under Lieutenant Commander J.M. Chaplin in 1927 and 1929, and was named in 1957 by the UK Antarctic Place-Names Committee for the sailing vessel "Ems", owned by the Tonsberg Hvalfangeri, Husvik, located at the head of Husvik Harbour in Stromness Bay.

Banaba Island: Banaba Island ( ; also Ocean Island), an island in the Pacific Ocean, is a solitary raised coral island west of the Gilbert Island chain and 185 mi east of Nauru.  It is part of the Republic of Kiribati.  It has an area of 6.0 km², and the highest point on the island is also the highest point in Kiribati, at 81 metres (266 ft) high.  Along with Nauru and Makatea (French Polynesia), it is one of the important elevated phosphate-rich islands of the Pacific.
