Trichaltica xantholimbia is a species of coleoptera insect of the family Chrysomelidae.
Trichaltica xantholimbia was described scientifically for the first time in 1997 by Bechyne. e domes of the Antarctic shell. Dome C is located in the Antarctic plateau at 1100 km inside the frigid white continent from the Dumont d'Urville Base in France, 1100 km from the Casey Base of Australia, and 1200 km from the Mario Zucchelli Base in Italy. the Terra Nova bay. The Russian Vostok Base is 560 km away. away. Dome C is the site where the Concordia Base is located, operated jointly by France and Italy.
HistoryIn the 1970s dome C was the site of drilling of the ice field by several nations. It was called in English Dome Charlie (code of the letter C in the radiophonic alphabet) by the U.S. Naval Support Force and its VXE-6 squadron, which provided logistical support to the field teams. In January and November of 1975, three LC-130 Hercules aircraft suffered severe damage during an attempt to land on the Charlie dome. In November of 1975 and November of 1976 the U.S. Navy established a camp in the Charlie dome to recover the planes. After major structural repairs and the replacement of engines in the camp, the three LC-130s flew to McMurdo Base on December 26, 1975, January 14, 1976 and Christmas Day 1976.
From November 1977 to March 1978 a French team of 13 people was installed in the existing camp left by the rescue teams of the aircraft. They took several tons of equipment, thanks to the VXE-6 aircraft and managed to drill up to 980 m by extracting columns of ice, which they later analyzed in their laboratories. The ice samples corresponded to between 45,000 and 50,000 years old.
During the austral summer of 1979-80, the camp was again occupied by Americans and French, under the auspices of the US Antarctic Research Program, sponsored by the National Science Foundation. Studies were carried out on the deep drilling of the ice core, meteorology and seismic. The camp, with a maximum population in summer of 18 people, was operated and maintained by four employees of ITT Antarctic Services and a member of the medical corps of the US Navy. When the camp was closed in January 1980, a remote station powered by nuclear power was left behind.
In 1992 France decided to build a new station on the Antarctic plateau; The program was later joined by Italy. In 1996 a Franco-Italian team established a summer camp in Dome C. The two main objectives of the camp were the provision of logistical support to the EPICA and the construction of a permanent research station. The new facility, the Concordia Base, came into operation in 2005. Subsequently, it was called the Concordia dome in honor of the aforementioned Franco-Italian scientific base. Environmental environment View of the high, flat, and cold environment of the Antarctic plateau in the dome C.
Dome C is one of the coldest places on Earth. Temperatures barely rise above -25 ° C in the summer and may fall below -80 ° C in the winter. The average annual air temperature is -54.5 ° C. The humidity is low and it is also very dry, with very little precipitation throughout the year.
Dome C does not experience the catabatic winds typical of the coastal regions of Antarctica due to its high location and relative distance from the edges of the Antarctic plateau. The typical wind speed in winter is 2.8 m / s.
Dome C is located at the top of the Antarctic plateau, the largest frozen desert in the world. No animal and / or any plant lives more than ten kilometers from the coasts of the Southern Ocean. However, they have been seen pá
