Dome F, also known as Dome Fuji ( Fujiドーム 富士domU ) or Valkyrjedomen, located in the eastern Queen Maud Land. With a height of 3,810 m above sea Dome F is the second highest peak or "dome" of the Antarctic ice sheet and thus forms an ice divide. There is a Japanese research station.

Climate

Due to the location on the high plateau of East Antarctica and the high altitude Dome F is one of the coldest places on earth. The temperature rises in the summer rarely above -30 ° C and can fall in winter down to -80 ° C. The annual mean of -54.3 ° C. The climate is that of a cold desert, water equivalent with very dry conditions and an annual rainfall of about 25 millimeters, which falls exclusively as snow.

Dome Fuji Station

The Dome Fuji Station (ドーム 富士 基地, Domu Fuji Kichi ) was (ドーム 富士 観測 拠点, Domu Fuji Kansoku Kyoten ) established in January 1995 as the "Dome -Fuji - observation basis." The name was changed on 1 April 2004 in " Dome Fuji Station". The distance to the Showa Station is about 1000 km.

Glaciology

A deep ice drilling was started in August 1995 at Dome F, and in December 1996 a depth of 2503 m was reached. This first dome F- core contains up to 340,000 year old ice.

The second deep core was started in 2003. It was drilled over four consecutive austral summer of 2003/2004 bis 2006/2007, with a depth of 3035.22 m was achieved. The bedrock was not reached, but there were found pieces of rock and re- frozen water ice in the bottom, indicating that the well has at least come very close to the rock bed. This core extends the climate archive of the first core sample considerably and ranges according to a first, preliminary dating back about 720,000 years in the past. Thus, the ice of the second dome F- drill core is the second oldest ever brought to light ice, only surpassed by that of the Dome C core sample.
