In 1906, Wegener participated in the first of his four Greenland expeditions, later regarding this experience as marking a decisive turning point in his life. The Denmark expedition was led by the Dane Ludvig Mylius-Erichsen and charged with studying the last unknown portion of the northeastern coast of Greenland.
In the end this venture would claim Wegener's life during a return trip from the Eismitte station together with expedition member Rasmus Villumsen. [2] Wegener had experience as an Arctic explorer. Previously he had taken part as a meteorologist in the 1906–1908 Danmark Expedition and the 1912-1913 Danish Expedition to Queen Louise Land.
The Wegener–Bergeron–Findeisen process (after Alfred Wegener, Tor Bergeron, and Walter Findeisen []), (or "cold-rain process") is a process of ice crystal growth that occurs in mixed phase clouds (containing a mixture of supercooled water and ice) in regions where the ambient vapor pressure falls between the saturation vapor pressure over water and the lower saturation vapor pressure over ice.
But A. Wegener did not have the specialisation to correctly weight the quality of the geophysical data and the paleontologic data, and its conclusions. Wegener's main interest was meteorology, and he wanted to join the Denmark-Greenland expedition scheduled for mid 1912. So he hurried up to present his Continental Drift hypothesis. [2]
Boris Choubert or Schuberth (1906 − December 3, 1983) was a Russian-French geologist. An adept of Wegener's theory, he was the first to precisely reconstruct the layout of the continental masses of Africa, America, Europe and Greenland prior to the fragmentation of Pangaea, thirty years before the article generally credited for this discovery.
A second problem was that Wegener's estimate of the speed of continental motion, 250 cm/year (100 in/year), was implausibly high. [34] (The currently accepted rate for the separation of the Americas from Europe and Africa is about 2.5 cm/year (1 in/year).) [35] Furthermore, Wegener was treated less seriously because he was not a geologist. Even ...
According to Daly's biographer, James Natland, Daly was an early proponent of Arthur Holmes and Alfred Wegener's continental drift theory. [5] Daly summarized his ideas in his 1926 book, Our Mobile Earth, which included on the title page small print adopted from Galileo: E pur si muove. Daly's theory on continental displacement was based partly ...
Ernst Sorge was a member of Alfred Wegener's expedition. Together with Johannes Georgi he stayed in Eismitte from July 1930 to August 1931. Fritz Loewe stayed from October 1930 to May 1931. Sorge hand-dug a 15 m deep pit adjacent to his subterranean snow cave, which served as living quarters during the seven-month-long overwintering.
