GEOGRAPHIC NAMES OF ANTARCTICA 



breaker Northwind, and submarine Sennet. This 

 group established a base on Ross Ice Shelf at Bay 

 of Whales, January 16, 1947. Six transport planes 

 were flown to the base from the carrier Philippine 

 Sea for 29 photographic flights over Ross Ice Shelf 

 and lands bordering the shelf to the west and south, 

 western Marie Byrd Land, and the polar plateau. 

 A tractor journey to Rockefeller Mountains was 

 made. A limited program of meteorology, glaci- 

 ology, and geophysics was carried on. The base 

 was evacuated on February 23, 1947 by the ice- 

 breaker Burton Island. Eastern group under Capt. 

 George J. Dufek consisted of seaplane tender Pine 

 Island, destroyer Brownson, and tanker Canisto. 

 This group rendezvoused near Peter I Island in 

 late December. Bad weather curtailed flights over 

 coastal area south of Bellingshausen Sea, and in 

 latter part of January the group moved Westward 

 and in clearer weather photographed the coast 

 south of Amundsen Sea, roughly between 100 °W. 

 and 125°W. This completed, the group returned 

 eastward with flights over Charcot and Alexander 

 I Islands, and by March had cruised east of the 

 Greenwich meridian with flights over Princess 

 Martha Coast. Western group under Capt. Charles 

 A. Bond consisted of seaplane tender Currituck, de- 

 stroyer Henderson, and tanker Cacapon. They 

 rendezvoused north of Balleny Islands in Decem- 

 ber, then cruised westward until March making 25 

 photographic flights over the continental margin 

 from Gates Coast, in 164°E., almost half way 

 around Antarctica to Princess Astrid Coast in 15°E. 

 Numerous geographic discoveries made, including 

 an ice free area close south of Queen Mary Coast. 



1947. Argentine expedition. 



Leader: Capt. Luis Miguel Garcia. Ships: King, 

 Murature, Ministro Ezcurra, Don Samuel, Gran- 

 ville, Patagonia, Chaco, and Fournier. 

 Summary: Sponsored by Comision Nacional del 

 Antartico and Ministry of Marine. The Patagonia 

 and Don Samuel proceeded from Ushuaia January 

 24, 1947, calling at Deception Island January 29, to 

 protest existence of Falkland Islands Dependencies 

 Survey Base B. On January 31a base was started 

 in Melchior Islands. An amphibian flight was 

 made southward from the Patagonia. Other ships 

 assisted in base construction while Garcia in the 

 Don Samuel sailed south to Marguerite Bay, call- 

 ing at Falkland Islands Dependencies Survey Base 

 E at Stonington Island. Automatic lighthouses 

 were erected at Py Point on Doumer Island, and 

 Cape Anna on Palmer Peninsula. Eight men, un- 

 der Lieutenant Nadau, remained to staff the Mel- 

 chior Islands base. A navigational beacon was 

 erected in May by the Fournier on Anvers Island. 

 The King and Murature carried on reconnaissance 

 in South Shetland Islands, South Orkney Islands, 

 and Weddell Sea. Personnel at the Argentine 



weather station on Laurie Island in South Orkney 

 Islands were relieved.

Leader: Capt. Frederico Guesalago Toro. Ships: 

 Iquique and Angamos. 



Summary: Sponsored by Chilean Navy. The ships 

 sailed from Valparaiso in January 1947. The 

 Iquique visited the South Shetland Islands, calling 

 at Deception Island, then sailed southward through 

 De Gerlache Strait to Marguerite Bay. The An- 

 gamos established a base at Discovery Bay, Green- 

 wich Island in the South Shetland Islands before 

 sailing south to Marguerite Bay in March. Five 

 men wintered on Greenwich Island under Lt. Boris 

 Kopaitic O'Neil.

 Antartico and Ministry of Marine. An ice recon- 

 naissance in Bransfield Strait was begun in No- 

 vember 1947 by the Bouchard, Granville, and King. 

 Construction of a base at Deception Island was 

 started in December. A survey flight by a navy 

 plane was made from Piedrabuena airfield in 

 Patagonia across Deception Island, Melchior Is- 

 lands, Adelaide Island and Palmer Peninsula. Ac- 

 tivities were carried on under escort of naval ves- 

 sels on maneuvers in Antarctic waters. Naviga- 

 tional lights were erected in Melchior Islands. A 

 temporary hut was erected at Admiralty Bay, King 

 George Island. A winter party under Lt. Roberto 

 A. Cabrera was left at Deception Island, and 

 another under Lt. L. Roque de Costillas at Melchior 

 Islands. 



1947-48. United States Navy Operation Windmill. 

 Leader: Cdr. Gerald L. Ketchum, USN. Ships: 

 Icebreakers Edisto and Burton Island. 

 Summary: Objective of expedition was to secure 

 ground control data for the aerial photography of 

 Operation Highjump by landing at several points 

 by means of helicopters. From Samoa the ships 

 forced their way into the ice of Davis Sea in 92°E. 

 in December 1947. Landing was made on Haswell 

 Islet. Ships then cruised eastward along the edge 

 of the pack with landings in about 105°E. and off 

 Knox Coast. McMurdo Sound, Bay of Whales, and
