Helm Point
Helm Point () is a point which marks the southeast tip of Honeycomb Ridge on the west side of Moubray Bay, Antarctica. It consists of brown granodiorite and supports a relatively luxuriant vegetation of lichens and mosses, along with nests of snow petrels and Wilson's petrels. Two Japanese whale-chasers, apparently familiar with the site, dropped anchor there for two nights early in February 1958. It was named by the New Zealand Geological Survey Antarctic Expedition, 1957–58, for Arthur S. Helm, secretary of the Ross Sea Committee, who gave much assistance to the expedition. Helm was also secretary of the New Zealand Antarctic Place-Names Committee New Zealand Antarctic Place-Names Committee (NZ-APC) is an adjudicating committee established to authorize the naming of features in the Ross Dependency on the Antarctic continent.

Granodiorite
Granodiorite () is a coarse-grained (phaneritic) intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar. The term banatite is sometimes used informally for various rocks ranging from granite to diorite, including granodiorite. Composition According to the QAPF diagram, granodiorite has a greater than 20% quartz by volume, and between 65% and 90% of the feldspar is plagioclase. A greater amount of plagioclase would designate the rock as tonalite. Granodiorite is felsic to intermediate in composition. It is the intrusive igneous equivalent of the extrusive igneous dacite. It contains a large amount of sodium (Na) and calcium (Ca) rich plagioclase, potassium feldspar, quartz, and minor amounts of muscovite mica as the lighter colored mineral components. Biotite and amphiboles often in the form of hornblende are more abundant in granodiorite than in granite, giving it a more distinct two-toned or overall darker appearan ...

Snow Petrel
The snow petrel (''Pagodroma nivea'') is the only member of the genus ''Pagodroma.'' It is one of only three birds that has been seen at the Geographic South Pole, along with the Antarctic petrel and the south polar skua, which have the most southerly breeding sites of any bird, inland in Antarctica. Taxonomy The snow petrel was described in 1777 by the German naturalist Georg Forster in his book ''A Voyage Round the World''. He had accompanied James Cook on Cook's second voyage to the Pacific. We particularly observed a petrel, about the size of a pigeon, entirely white, with a black bill and blueish feet; it constantly appeared about the icy masses, and may be looked upon as a sure fore-runner of ice. Forster placed the snow petrel in the genus ''Procellaria'' that had been erected for the petrels by Carl Linnaeus in 1758 and coined the binomial name ''Procellaria nivea''. The snow petrel is now the only species placed in the genus ''Pagodroma'' that was introduced for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilson's Petrel
Wilson's storm petrel (''Oceanites oceanicus''), also known as Wilson's petrel, is a small seabird of the austral storm petrel family Oceanitidae. It is one of the most abundant bird species in the world and has a circumpolar distribution mainly in the seas of the southern hemisphere but extending northwards during the summer of the northern hemisphere. The world population was estimated in 2022 as stable at 8 to 20 million birds. In 2010 it had been estimated at 12-30 million. A 1998 book had estimated more than 50 million pairs. The name commemorates the Scottish-American ornithologist Alexander Wilson. The genus name ''Oceanites'' refers to the mythical Oceanids, the three thousand daughters of Tethys. The species name is from Latin ''oceanus'', "ocean". Taxonomy Originally described in the genus ''Procellaria'' it has been placed under the genus ''Oceanites''. Two or three subspecies are recognized and one population ''maorianus'' from New Zealand may be extinct. The nomin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arthur S
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ma ...

New Zealand Antarctic Place-Names Committee
New Zealand Antarctic Place-Names Committee (NZ-APC) is an adjudicating committee established to authorize the naming of features in the Ross Dependency on the Antarctic continent. It is composed of the members of the New Zealand Geographic Board plus selected specialists on Antarctica. This committee works in collaboration with similar place-naming authorities in Australia, Great Britain and the United States to reach concurrence on each decision. The NZ-APC committee was established in 1956.

Headlands Of Victoria Land
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
