Base Presidente Eduardo Frei Montalva is the most important Antarctic base of Chile. It is located at Fildes Peninsula, an ice-free area, in front of Fildes Bay (Maxwell Bay), west of King George Island, South Shetland Islands. Situated alongside the Escudero Station and only 200 metres from the Russian Bellingshausen Station, its geographic coordinates are 62°12′0″S 58°57′51″W / 62.20000°S 58.96417°W / -62.20000; -58.96417, with an altitude of 10 metres above sea-level. The base is located in the Chilean commune of Antártica, which is the Antarctic territory claimed by Chile[1] (Antártica Chilena Province, Magallanes y la Antártica Chilena Region).

Also nearby are the bases of Great Wall (People's Rep. of China), General Artigas Station (Uruguay), King Sejong Station (Republic of Korea), Carlini Base (Argentina), Commandante Ferraz (Brazil), Henryk Arctowski (Poland) and Machu Picchu Base (Peru). Much further away is Captain Arturo Prat Base, also Chilean, 50 km to the west.

Description[edit]

It has a 1300 meters long airstrip (Teniente Rodolfo Marsh Martin Aerodrome, ICAO Code SCRM,[2] with 50 intercontinental and 150 intracontinental flights each season, serving as a means of transport to many bases around. It also includes the Villa Las Estrellas residential area that has an hospital, a school, a bank, a small supermarket, etc. The maximum population during summer is of 150 people, and the average during winter is of about 80 people.[3]

It began to operate in 1969 as Centro Meteorológico Eduardo Frei. When the installations were expanded, it was renamed as Base Teniente Rodolfo Marsh, with the meteorology center keeping its original name. During the 1990 decade, all of the installations came to be named Base Presidente Eduardo Frei Montalva, with the airstrip retaining the name Teniente Rodolfo Marsh.[4]

Climate[edit]

Like the coastal areas of Antarctic Peninsula and the subantarctic islands south of the 60º parallel, the area has a tundra climate, that could be considerably borderline "maritime-influenced polar climate", thanks to temperatures that hardly drops below -15 degrees in winter (which is commonplace in most of Antarctica), and temperatures that could soar a few digits above freezing for most parts of the year. The base's area and its vicinity (the entire island, actually) experiences a rather heavy precipitation, with an average precipitation rate of 405 mm yearly [5], which makes it rather unique to the Antarctic continent, as the continent is significantly drier then the islands are to the north.
