Mount Demaria
Mount Demaria () is a mountain with precipitous sides, high, rising immediately southeast of Cape Tuxen on the west coast of Kyiv Peninsula in Graham Land. It was probably first sighted by the Belgian Antarctic Expedition of 1897–99. It was charted by the French Antarctic Expedition of 1903–05 and was named by Jean-Baptiste Charcot Jean-Baptiste-Étienne-Auguste Charcot (15 July 1867 – 16 September 1936), born in Neuilly-sur-Seine, was a French scientist, medical doctor and polar scientist.

Kyiv Peninsula
Kyiv Peninsula (, ) is the predominantly ice-covered, oval shaped peninsula projecting 35 km in northwest direction from the west side of Graham Land, Antarctic Peninsula. It is bounded by Flandres Bay to the northeast and Beascochea Bay to the southwest, and separated from Wilhelm Archipelago to the northwest by Lemaire Channel and Penola Strait. The peninsula's north extremity Cape Renard divides Graham Coast to the southwest from Danco Coast to the northeast. Mount Demaria is found on the west coast of the peninsula. Etymology The feature was first described and named in 2010 by the Antarctic Place-names Commission of Bulgaria after the capital city of Ukraine, in connection with the Ukrainian Antarctic base Vernadsky situated on nearby Galindez Island. The original naming was done in Bulgarian ( bg, полуостров Киев, poluostrov Kiev, ). Later, the name was adopted also by Ukraine in 2020 and translated ''Kyiv Peninsula''.

Graham Land
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking pay ...

Belgian Antarctic Expedition
The Belgian Antarctic Expedition of 1897–1899 was the first expedition to winter in the Antarctic region. Led by Adrien de Gerlache de Gomery aboard the RV ''Belgica'', it was the first Belgian Antarctic expedition and is considered the first expedition of the Heroic Age of Antarctic Exploration. Among its members were Frederick Cook and Roald Amundsen, explorers who would later attempt the respective conquests of the North and South Poles. Preparation and surveying In 1896, after a period of intensive lobbying, Adrien Victor Joseph de Gerlache de Gomery purchased the Norwegian-built whaling ship ''Patria'', which, following an extensive refit, he renamed . Gerlache had worked together with the Geographical Society of Brussels to organize a national subscription, but was able to outfit his expedition only after the Belgian government voted in favor of two large subsidies, making it a state-supported undertaking. With a multinational crew that included Roald Amundsen from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Antarctic Expedition, 1903–05
The French Antarctic Expedition is any of several French expeditions in Antarctica. First expedition In 1772, Yves-Joseph de Kerguelen-Trémarec and the naturalist Jean Guillaume Bruguière sailed to the Antarctic region in search of the fabled Terra Australis. Kerguelen-Trémarec took possession of various Antarctic territories for France, including what would later be called the Kerguelen Islands. In Kerguelen-Trémarec's report to King Louis XV, he greatly overestimated the value of the Kerguelen Islands. The King sent him on a second expedition to Kerguelen in late 1773. When it became clear that these islands were desolate, useless, and not the Terra Australis, he was sent to prison. Second expedition In 1837, during an 1837–1840 expedition across the deep southern hemisphere, Captain Jules Dumont d'Urville sailed his ship ''Astrolabe'' along a coastal area of Antarctica which he later named Adélie Land, in honor of his wife. During the Antarctic part of this exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Charcot
Jean-Baptiste-Étienne-Auguste Charcot (15 July 1867 – 16 September 1936), born in Neuilly-sur-Seine, was a French scientist, medical doctor and polar scientist. His father was the neurologist Jean-Martin Charcot (1825–1893). Life Jean-Baptiste Charcot was appointed leader of the French Antarctic Expedition with the ship ''Français'' exploring the west coast of Graham Land from 1904 until 1907. The expedition reached Adelaide Island in 1905 and took pictures of the Palmer Archipelago and Loubet Coast. From 1908 until 1910, another expedition followed with the ship '' Pourquoi Pas ?'', exploring the Bellingshausen Sea and the Amundsen Sea and discovering Loubet Land, Marguerite Bay, Mount Boland and Charcot Island, which was named after his father, Jean-Martin Charcot. anhere./ref> He named Hugo Island after Victor Hugo, the grandfather of his wife, Jeanne Hugo.

Anastigmat
An anastigmat or anastigmatic lens is a photographic lens completely corrected for the three main optical aberrations: spherical aberration, coma, and astigmatism. Early lenses often included the word ''Anastigmat'' in their name to advertise this new feature (''Doppel-Anastigmat'', ''Voigtländer Anastigmat Skopar'', etc.). The first Anastigmat was designed by Paul Rudolph for the German firm Carl Zeiss AG in 1890. All modern photographic lenses are close to being anastigmatic, meaning that they can create extremely sharp images for all objects across their field of view; the underlying limitation is that the lens can deliver the anastigmatic performance only up to a maximum aperture (i.e., it has a minimum F-number) and only within a given working distance (focusing range). Note that all optical aberrations (except spherical aberration) become more pronounced towards the edges of the field of view, even with high-grade anastigmatic lenses. Anastigmatic performance is accomplis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Graham Land
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...
