Adelie Coast

Antarctica, which he named the Adelie Coast (67°00 S, 139°00 E) in honor of his wife. 

The claim to Adelie Land which Dumont d Urville had discovered was not recognized until 1926 because it was not clear whether d Urville or Wilkes had actually seen it first. Finally, on January 20 of 1950, a group of scientists of the French Polar Expedition landed on the Adelie coast to set up a base which was named Dumont d Urville in honor of the famous navigator and explorer (Stonehouse 2002). 

The magnetic pole in Antarctica was eventually discovered in 1909 by T.W. Edgeworth David at 72°025 S and 115°16 E in the interior of the continent behind the mountains of Victoria Land. David was a member of the so-called Nimrod Expedition of 1907-1909 that was led by Ernest Shackleton (1874-1922). Since its discovery in 1909, the magnetic pole in Antarctica has moved 900 km to its present position at 65°S and 139°E in the Indian Ocean off the Adelie Coast of East Antarctica (Stonehouse 2002, p. 169). However, nearly 50 years elapsed before the map of the magnetic field in Antarctica was completed during the International Geophysical Year that lasted from 1957-1958 (Victor 1964). 

Fig. 17.25 The traverse by C. Lorius and L. Merlivat started from the French research station Dumont D Urville on the Adelie Coast and proceeded toward Dome C. The purpose was to relate the 5D values of firn to the elevation above sea level and to the average annual temperature of the stops along the way. The length of the traverse was close to 900 km. Dome C is located along the central ice divide of the East Antarctic ice sheet (Adapted from Figure 1 of Lorius and Merlivat 1977)...

In addition, the values of snow that can be calculated from the 5D values measured by Lorius and Merlivat (1977) rise from -48%o to -20%o with increasing average annual temperature from -60°C near Dome C and -20°C at the Adelie Coast. The resulting graph in Fig. 17.27 includes the values of ice at the Elephant and Reckling moraines (E and R) and the Allan Hills (A). These empirical relationships relate the and 5D values of the ice to the climatic conditions at the time the snow was deposited. Although the climate history that is contained in the ice is destroyed by the deformation of the ice when it flows from its source to the area adjacent to the Transantarctic... 

Fig. 17.27 The values of snow and firn, calculated from the measured 5D values in Fig. 17.26, decrease progressively with decreasing average annual temperature of the collecting sites. These values refer to the snow and firn of the collecting sites and not to the underlying ice which is not exposed along the Adelie Coast of East Antarctica. However, the crosses are the measured values of ice at the Elephant (E) and...

The first meteorite discovered in Antarctica was found by a member of Douglas Mawson s expedition from 1911 to 1914 to the Adelie Coast (67°00 S, 139°00 E) of East Antarctica. The meteorite was collected in Commonwealth Bay about 43 km west of Cape Dennison... 

Although large meteorites have certainly impacted in Antarctica, only one such crater has been tentatively identified under the ice at about 71°30 S, 140°00 E in Wilkes Land south of the Adelie coast. Another more speculative meteorite impact crater may exist at Butcher Ridge (79°12 S, 155°48 E) in the Cook Mountains of southern Victoria Land.

Fig. 1.3 Jules C. Dumont d Urville (1790-1842) was a French naval officer and navigator who led the French Naval Expedition to Antarctica from 1837 to 1840. He was an experienced explorer who had worked in the eastern Mediterranean Sea followed by two expeditions to map the coasts of Australia and New Zealand and to map variations of the magnetic field in the South Pacific euid the Southern Ocean. He used two ships (Astrolabe and Zelee) in eui attempt to find the magnetic pole in Antarctica Although he failed to achieve that objective, he named Adelie Land along the coast of East Antarctica after his wife and discovered two large islands off the coast of the Antarctic Peninsula (Photo by the Scott Polar Research Institute, University of Cambridge, used here with permission)...
