Mount Hercules
Mount Hercules () is a large, flat-topped, elevated feature between Mount Aeolus and Mount Jason in the Olympus Range of Victoria Land, Antarctica. It was named by the Victoria University of Wellington Antarctic Expedition (1958–59) for Hercules, a figure in Greek mythology. Marsh Cirque is a cirque on the southern slopes of Mount Hercules. The cirque is wide and in part occupied by a glacier. It was named by the Advisory Committee on Antarctic Names in 2004 after geologist Bruce D. Marsh, of the Department of Earth and Planetary Sciences, Johns Hopkins University, Baltimore, Maryland. Marsh investigated basement sill at McMurdo Dry Valleys sites in seven field seasons, 1995–2005, for the United States Antarctic Program.

Olympus Range () is a primarily ice-free mountain range of Victoria Land, Antarctica, with peaks over , between Victoria and McKelvey Valleys on the north and Wright Valley on the south. It was mapped by the Victoria University of Wellington Antarctic Expedition, 1958–59, and named for the mythological home of the Greek gods. Peaks in the range are named for figures in Greek mythology. Further reading * I.B. Campbell, G.G.C.

McMurdo Dry Valleys
The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape, with loose gravel covering the ground. It is one of the driest places on Earth and has not seen rain for nearly two million years. The region is one of the world's most extreme deserts, and includes many features including Lake Vida, a saline lake, and the Onyx River, a meltwater stream and Antarctica's longest river. Although no living organisms have been found in the permafrost here, endolithic photosynthetic bacteria have been found living in the relatively moist interior of rocks, and anaerobic bacteria, with a metabolism based on iron and sulfur, live under the Taylor Glacier. The valleys are located within the McMurdo Valleys Antarc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earth Sciences
Earth science or geoscience includes all fields of natural science related to the planet Earth. This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres, namely biosphere, hydrosphere, atmosphere, and geosphere. Earth science can be considered to be a branch of planetary science, but with a much older history. Earth science encompasses four main branches of study, the lithosphere, the hydrosphere, the atmosphere, and the biosphere, each of which is further broken down into more specialized fields. There are both reductionist and holistic approaches to Earth sciences. It is also the study of Earth and its neighbors in space. Some Earth scientists use their knowledge of the planet to locate and develop energy and mineral resources. Others study the impact of human activity on Earth's environment, and design methods to protect the planet. Some use their knowledge about Earth processes ...

Nagoya University
, abbreviated to or NU, is a Japanese national research university located in Chikusa-ku, Nagoya. It was the seventh Imperial University in Japan, one of the first five Designated National University and selected as a Top Type university of Top Global University Project by the Japanese government.

McMurdo Dry Valleys Drilling Project
Vice-Admiral Archibald McMurdo (24 September 1812 – 11 December 1875) was a Scottish naval officer and polar explorer after whom Antarctica's McMurdo Sound, McMurdo Station, McMurdo Ice Shelf, McMurdo Dry Valleys and McMurdo–South Pole Highway are named. Early life Archibald William McMurdo was born on September 24, 1812 in Scotland. He was the son of Lieutenant Colonel Archibald McMurdo and grandson of John McMurdo, a chamberlain at Drumlanrig Castle. Career McMurdo joined the Royal Navy on 6 October 1824, at the age of 12. He was promoted to Lieutenant in 1836 for his skill and courage in saving the crew of a shipwrecked whaler from hostile New Zealand natives. He achieved the rank of Commander in 1843 and Captain in 1851. His career included two discovery expeditions aboard HMS ''Terror'', the first to Hudson Bay (1836-1837), the second to Antarctica (1839-1842).

Landforms Of Victoria Land
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Fields Of The Ross Dependency
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or Sublimation (phase transition), sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes Nucleation, nucleate around particles in the atmosphere by attracting supercooling, supercooled water droplets, which Freezing, freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and Hard rime, rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
