| description | The Ushuaia Station is located on the "Isla Grande de la Tierra del Fuego", Argentina (54° 50' S - 68° 18' W), roughly 10 km south-west of the city of Ushuaia. The station is located in a coastal cliff at an altitude of 18 m a.s.l., on a remote sub-Antarctic marine coast. Steady winds blow prevailing from the clean air sector (SW) down the Beagle Channel. Tierra del Fuego and its adjacent oceanic area are under the westerlies influence. The ground in the vicinity around the station is covered with pasture and bush. The vegetation in the surrounding area (30 Km) is consisting mainly of Nothofagus forest. The facilities at the site consist of the main building of 230 m2, which provides space for offices, meeting rooms and laboratories. Attached to this building is the Dobson spectrophotometer. On the platform at the top of the roof, the air inlet and several radiation and meteorological equipment are mounted. In addition to the main facility, a remote island sampling site with a 12 m tower called "Isla Redonda" is located on Beagle Channel (54° 51' S - 68° 28' W) and can be used for special projects. Since two years, the new Ushuaia airport has opened in the near vicinity of the station. It is located about 500 mts. north-east of the site towards the city of Ushuaia. Air traffic is estimated to 5-10 flight movements per day. As already stated in the first audit report '94 (Martini, Slemr, Mohnen) there is some concern regarding a possible influence of the measurements, in particular when the airport should further develop. |
