Melchior Base
Melchior Base (Spanish: Base Melchior or, seldom, Estación Melchior) is an Argentine Antarctic base and scientific research station. It is located on Gamma Island (which the Argentines call Isla Observatorio), Melchior Islands, Dallmann Bay, in Palmer Archipelago on Bellingshausen Sea, Antarctic Peninsula.
It is Argentina's second historical Antarctic base, after the 1904 establishment of the Orcadas Naval Detachment, the world's first—and oldest—permanent settlement in Antarctica.
As of 2014[update] Melchior is one of 13 research bases in Antarctica operated by Argentina. From 1947 to 1961 it served as a permanent base; since then it is open during the summer season only.
In January 1942 the Argentine Navy transport ARA Primero de Mayo, commanded by then Frigate Captain Alberto J. Oddera, departed from Buenos Aires with the mission of studying the western coast of the Antarctic Peninsula, especially the area of the Melchior and Argentine Islands. In the former the expedition built a lighthouse and daybeacon.
The archipelago was visited again the following year to continue with the cartographic work and to do maintenance duties on the lighthouse. Three years later, in 1946, the National Antarctic Commission sponsored a new exploration trip.
This new expedition sailed away from the continent in January 1947, led by then Frigate Captain Luis M. García. It was made up of the light transports Patagonia and Chaco, the patrol ships ARA King and ARA Murature, the tanker Ministro Ezcurra and the whaler Don Samuel. The expedition arrived in Observatorio Island on the last day of 1947, and set up a hydrographic camp and basic astronomical observatory at Punta Gallows.
It took 47 days of labor to dynamite the rock, lay down the groundwork for the radio antennae and build the main house: a semi-prefabricated building 27 m (89 ft) long and 7.50 m (24.6 ft) wide, with thermally insulated double walls and ceilings. It had a water boiler, two power generators, batteries and several radio transmitters.
Two 25 m (82 ft) high antennae made possible to communicate with Buenos Aires through radio telegraphy. They also erected four 18 m (59 ft) towers for the 100 m (330 ft) per side rhombic antenna.
