Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antarctic Place-names Commission
The Antarctic Place-names Commission was established by the Bulgarian Antarctic Institute in 1994, and since 2001 has been a body affiliated with the Ministry of Foreign Affairs of Bulgaria. The Commission approves Bulgarian place names in Antarctica, which are formally given by the President of the Republic according to the Bulgarian Constitution (Art. 98) and the established international practice. Bulgarian names in Antarctica Geographical names in Antarctica reflect the history and practice of Antarctic exploration. The nations involved in Antarctic research give new names to nameless geographical features for the purposes of orientation, logistics, and international scientific cooperation. As of 2021, there are some 20,091 named Antarctic geographical features, including 1,601 features with names given by Bulgaria.Bulgarian Antarctic Gazett ...

Desolation Island (South Shetland Islands)
Desolation Island is one of the minor islands in the South Shetlands archipelago, Antarctica situated at the entrance to Hero Bay, Livingston Island. The island is V-shaped with its northern coast indented by Kozma Cove. Surface area .L.L. Ivanov. Antarctica: Livingston Island and Greenwich, Robert, Snow and Smith Islands. Scale 1:120000 topographic map. Troyan: Manfred Wörner Foundation, 2010. (First edition 2009. ) The island was discovered on 15 October 1819 by Captain William Smith in the English merchant brig ''Williams'' during his second visit to the islands. The anchorage Blythe Bay at the southeast side of Desolation Island was frequented by the early Nineteenth century English and American sealers. Location The island's midpoint is located at , with the island lying northwest of Kotis Point, west of Williams Point and north-northeast of Siddins Point.

Avitohol Point
Avitohol Point ( bg, нос Авитохол, nos Avitohol, ) is a point on the north coast of Livingston Island, Antarctica projecting into Hero Bay to form the west side of the entrance to Skravena Cove and the southeast side of the entrance to Prisoe Cove. It is surmounted by Fletcher Nunatak and Belev Nunatak. The point is named after the legendary Khan Avitohol listed in the 8th Century '' Nominalia of the Bulgarian Khans'', who laid the foundations of the Bulgarian statehood in Europe in 165 AD. Location The point is located at which is northeast of Snow Peak, west-southwest of Siddins Point, south-southeast of Black Point and southeast of Cape Shirreff.

Hero Bay
A hero (feminine: heroine) is a real person or a main fictional character who, in the face of danger, combats adversity through feats of ingenuity, courage, or strength. Like other formerly gender-specific terms (like ''actor''), ''hero'' is often used to refer to any gender, though ''heroine'' only refers to women. The original hero type of classical epics did such things for the sake of glory and honor. Post-classical and modern heroes, on the other hand, perform great deeds or selfless acts for the common good instead of the classical goal of wealth, pride, and fame. The antonym of ''hero'' is ''villain''. Other terms associated with the concept of ''hero'' may include ''good guy'' or ''white hat''. In classical literature, the hero is the main or revered character in heroic epic poetry celebrated through ancient legends of a people, often striving for military conquest and living by a continually flawed personal honor code. The definition of a hero has changed th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Shetland Islands
The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province) and Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province). Several countries maintain research stations on the islands. Most of them are situated on King George Island, benefitting from the airfield of the Chilean base Eduardo Frei. There are sixteen research stations in different parts of the islands, with Chilean stations being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geodesy
Geodesy ( ) is the Earth science of accurately measuring and understanding Earth's figure (geometric shape and size), orientation in space, and gravity. The field also incorporates studies of how these properties change over time and equivalent measurements for other planets (known as '' planetary geodesy''). Geodynamical phenomena, including crustal motion, tides and polar motion, can be studied by designing global and national control networks, applying space geodesy and terrestrial geodetic techniques and relying on datums and coordinate systems. The job title is geodesist or geodetic surveyor. History Definition The word geodesy comes from the Ancient Greek word ''geodaisia'' (literally, "division of Earth"). It is primarily concerned with positioning within the temporally varying gravitational field. Geodesy in the German-speaking world is divided into "higher geodesy" ( or ), which is concerned with measuring Earth on the global scale, and "practical geodes ...

Theodolite
A theodolite () is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but it is also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching. It consists of a moveable telescope mounted so it can rotate around horizontal and vertical axes and provide angular readouts. These indicate the orientation of the telescope, and are used to relate the first point sighted through the telescope to subsequent sightings of other points from the same theodolite position. These angles can be measured with accuracies down to microradians or seconds of arc. From these readings a plan can be drawn, or objects can be positioned in accordance with an existing plan. The modern theodolite has evolved into what is known as a total station where angles and distances are measured electronically, and ...
