GEOGRAPHIC NAMES OF ANTARCTICA 



1947-48. Norwegian expedition. 

 Leader: Capt. Nils Larsen. Ship: Brategg. 

 Summary: Sponsored by Norske Hvalfangstsels- 

 kapers Forbund (Federation of Norwegian Whaling 

 Companies). Oceanographic research carried on 

 from Peter I Island westward to 174°31'W., north 

 of Ross Sea, following a zigzag course between the 

 edge of the pack and 62°00'S. On returning a 

 landing was made on Peter I Island for geological 

 and zoological work. Ship departed February 13, 

 1948 for Deception Island. The oceanographic 

 program was mainly planned by the Norske Geo- 

 grafiske Selskabs Havforsknings Komite (Commit- 

 tee of Oceanographic Investigation of the Nor- 

 wegian Geographic Society) . 



1947-48. Ronne Antarctic Research Expedition. 

 Leader: Cdr. Finn Ronne, USNR. Ship: Port of 

 Beaumont, Texas. 



Summary: Sponsored by American Geographical 

 Society, Office of Naval Research, Air Force, and 

 private donors, with aid of equipment borrowed 

 from government agencies. Expedition sailed with 

 three planes from Beaumont, Texas, on January 

 23, 1947, through Panama Canal, and arrived in 

 Marguerite Bay March 12. Former East Base of 

 the United States Antarctic Service on Stonington 

 Island was reoccupied and the Port of Beaumont, 

 Texas frozen in for the winter. Seismological, 

 meteorological, and geophysical observations car- 

 ried on continuously at base; cosmic rays and 

 marine tides were studied. During flying season, 

 weather stations were maintained on the plateau 

 east of the base and at Cape Keeler on east coast 

 of Palmer Peninsula. Two major sledge journeys, 

 a geological trip to George VI Sound and a joint 

 trip with the Falkland Islands Dependencies Sur- 

 vey from Stonington Island to the east coast of 

 Palmer Peninsula and south to Bowman Peninsula 

 in 74°47'S., 62°22'W., were carried out with air 

 support. Nine major exploratory flights were 

 made, resulting in 14,000 tri-metrogon aerial 

 photographs. Several landings made in the field 

 for geographical fixes and refueling. On Novem- 

 ber 7, 1947 a triangular course was flown over 

 Weddell Sea in the vicinity of Hearst Island. On 

 November 21 a flight was made south along the 

 east coast of Palmer Peninsula, landing on the ice 

 in Gardner Inlet in 74°48'S., 62°50'W. to refuel, 

 and then southwestward to Mount Hassage on 

 Joerg Plateau. The edge of Filchner Ice Shelf at 

 the head of Weddell Sea was next examined. 

 Plane was forced down by fog off Cape Knowles on 

 return to base, which was reached on November 

 22. On November 27 a flight was made northward 

 to Marin Darbel Bay, then southwestward over 

 Alexander I Island. On December 3, George VI 

 Sound was explored from the air southward to 

 Batterbee Mountains, after which a flight was made 



across central Alexander I Island. Second flight 

 to head of Weddell Sea began December 8, but 

 heavy overcast forced planes down off Cape Wheeler 

 until December 12 when the flight was continued 

 south and eastward along edge of the ice shelf to 

 78°30'S., 42°00'W. On December 22 and 23 flights 

 were made northward beyond 66°S. on both sides 

 of Palmer Peninsula. Last major flight occurred 

 on December 23, flying southward along east side 

 of George VI Sound, then west-southwest along its 

 southern shore and landing at 74°30'S., 79°00'W. 

 Plane then flew northeastward over Alexander I 

 Island, then northwest to Charcot Island where 

 another landing was made before returning to base. 

 The expedition evacuated its base on February 20, 

 1948. 



1947^8. Falkland Islands Dependencies Survey. 

 Leader: Maj. K. S. P. Butler. Ships: Fitzroy and 

 Trepassey. 



Summary: Sponsored by British Colonial Office. 

 Base A, the meteorological station at Port Lockroy, 

 was evacuated and closed for the winter April 9, 

 1947. Base B at Deception Island was rebuilt fol- 

 lowing a fire and maintained as a weather station 

 with flve men; a plane table survey was carried on. 

 Base C, Laurie Island, was evacuated March 17, 

 1947. Base D, Hope Bay, was relieved in February 

 1947. A weather station was maintained at Hope 

 Bay and a survey of Prince Gustav Channel com- 

 pleted. Depots were laid as far as Seal Nunataks 

 in support of a long sledge journey south along the 

 east coast of Palmer Peninsula which was begun 

 October 27, 1947. This group was met near Three 

 Slice Nunatak by a joint (Ronne Antarctic Re- 

 search Expedition - Falkland Islands Dependencies 

 Survey) assisting party from Stonington Jsland, 

 which guided them across the peninsula to Stoning- 

 ton Island. Base E, Stonington Island, was re- 

 lieved February 5, 1947. A staff of 11 maintained 

 a weather station there and, in cooperation with 

 the Ronne expedition, a station on the plateau 

 east of the base. They assisted Ronne's geological 

 party on first part of journey into George VI 

 Sound and from October 9, 1947 to January 16, 

 1948 participated in a joint British- American 

 sledge journey, with air support by Ronne, south- 

 ward along the east coast of Palmer Peninsula 

 from Joerg Peninsula in 68°12'S., 65°12'W. to Bow- 

 man Peninsula in 74°47'S., 62°22'W. At Base F, 

 Argentine Islands, a- new building was erected in 

 January 1947 to replace the old hut of the British 

 Graham Land Expedition which had been de- 

 stroyed along with an emergency depot by a tidal 

 wave. Four man staff at Base F operated a 

 weather station, supplied seal meat for the other 

 bases, and bred sledge dogs. Base G at Admiralty 

 Bay, King Geprge Island, was established as two 

 man weather station in January 1947. Erection
