Astraea Nunatak
Astraea Nunatak () is a nunatak south of Staccato Peaks in southern Alexander Island. It was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50, and named by the United Kingdom Antarctic Place-Names Committee after Astraea, one of the asteroids lying between the orbits of Mars and Jupiter. Geology According to the British Antarctic Survey's (BAS) aeromagnetic 1975 survey of Astraea Nunatak and nearby Ceres Nunataks, this geographical feature is rich in the igneous rocks Diorite and Tonalite as presumed by the rock samples which were observed by BAS during this survey. Aeromagnetic Survey of Astraea Nunatak and Ceres Nunataks In December 1975, the British Antarctic Survey (BAS) (originally known as the Falkland Islands Dependencies Survey (FIDS)) embarked on an 8-week long survey observing the proposed theory of Astraea Nunatak and Ceres Nunataks havin ...

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burn R
A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ultraviolet radiation (like sunburn). Most burns are due to heat from hot liquids (called scalding), solids, or fire. Burns occur mainly in the home or the workplace. In the home, risks are associated with domestic kitchens, including stoves, flames, and hot liquids. In the workplace, risks are associated with fire and chemical and electric burns. Alcoholism and smoking are other risk factors. Burns can also occur as a result of self-harm or violence between people (assault). Burns that affect only the superficial skin layers are known as superficial or first-degree burns. They appear red without blisters and pain typically lasts around three days. When the injury extends into some of the underlying skin layer, it is a partial-thickness or second-degree burn. Blisters are frequently present and they are often very painful. Healing can require up to eight weeks and scarri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 paying ...

Lassus Mountains
The Lassus Mountains () are a large group of mountains, long and wide, rising to and extending south from Palestrina Glacier in the northwest part of Alexander Island, Antarctica. They overlook Lazarev Bay and a few minor islands within the bay such as Dint Island and Umber Island; Haydn Inlet lies to the south while the Havre Mountains lie immediately north. The mountains were probably first seen on January 9, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen. They were photographed from the air in 1936 by the British Graham Land Expedition but mapped as part of the Havre Mountains. They were first mapped in detail, from air photos taken by the Ronne Antarctic Research Expedition (1947–48), by D. Searle of the Falkland Islands Dependencies Survey in 1960, and were named by the UK Antarctic Place-Names Committee after Orlandus Lassus, a Belgian composer of the 16th century.
