Scott Base
Scott Base is a New Zealand Antarctica, Antarctic research station at Pram Point on Ross Island near Mount Erebus in New Zealand's Ross Dependency territorial claim. It was named in honour of Captain Robert Falcon Scott, Royal Navy, RN, leader of two United Kingdom, British expeditions to the Ross Sea area of Antarctica. The base was set up as support to field research and the centre for research into earth sciences, and now conducts research in many fields, operated by Antarctica New Zealand. The base is from the larger U.S. McMurdo Station via Pegasus Road. History Scott Base was originally constructed in support of the UK inspired and privately managed Commonwealth Trans-Antarctic Expedition (TAE). The New Zealand government provided support for the TAE and also for the International Geophysical Year (IGY) project of 1957, five of whose members were attached to the Expedition. In February 1956, 10 months before the TAE and IGY parties were due to head to the Antarctic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macquarie Island
Macquarie Island is an island in the southwestern Pacific Ocean, about halfway between New Zealand and Antarctica. Regionally part of Oceania and politically a part of Tasmania, Australia, since 1900, it became a Tasmanian State Reserve in 1978 and was inscribed as a UNESCO World Heritage Site in 1997. It was a part of Esperance Municipality until 1993, when the municipality was merged with other municipalities to form Huon Valley Council. The island is home to the entire royal penguin population during their annual nesting season. Ecologically, the island is part of the Antipodes Subantarctic Islands tundra ecoregion. Since 1948, the Australian Antarctic Division (AAD) has maintained a permanent base, the Macquarie Island Station, on the isthmus at the northern end of the island at the foot of Wireless Hill. The population of the base, constituting the island's only human inhabitants, usually varies from 20 to 40 people over the year. A heliport is located nearby. In Septemb ...

Hope Black
Hope Black (''née'' MacPherson, 1919 – 25 January 2018) was an Australian scientist, a marine biologist and malacologist. In 1937 she started working at the National Museum of Victoria. Subsequently, she became Curator of Molluscs at the museum in 1946. One of the first four women to carry out research in the sub-Antarctic in 1959. She was the National Museum's first female curator. When she married in 1965, she was forced to leave the museum, and instead became a science teacher for thirteen years. In 2019 Lake Macpherson on Macquarie Island was named for her. Career Appointed as Curator of Mollusks in 1946, Hope MacPherson was Australia's first female curator at the National Museum of Victoria. Her tenure was brought to a close prematurely, when in 1965 she married and became Hope Black, requiring her retirement from the Victorian public service as a result of the marriage bar. Subsequently, Black worked for 13 years as a science teacher. Work in marine biology Hope Black ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isobel Bennett
Isobel Ida Bennett AO 1984 (9 July 1909 – 12 January 2008) was one of Australia's best-known marine biologists. She (with Elizabeth Pope) assisted William John Dakin with research for his final book (Australian Seashores) regarded by many as "the definitive guide on the intertidal zone, and a recommended source of information to divers". Following Dakin's death in 1950, she saw the book through to publication in 1952, and she continued to revise and reprint it with a complete revision in 1980 until 1992. In later editions, she was listed as a co-author, then first author. She also wrote nine other books, and was one of the first women (along with Susan Ingham, Mary Gillham & Hope Macpherson) to go south with the Australian National Antarctic Research Expeditions (ANARE). Life and career Isobel Ida Bennett was born in Brisbane in 1909 and educated at Somerville House leaving at the age of 16 when her family moved to Sydney. She attended business college and gained empl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Academy Of Science
The Australian Academy of Science was founded in 1954 by a group of distinguished Australians, including Australian Fellows of the Royal Society of London. The first president was Sir Mark Oliphant. The academy is modelled after the Royal Society and operates under a Royal Charter; as such, it is an independent body, but it has government endorsement. The Academy Secretariat is in Canberra, at the Shine Dome. The objectives of the academy are to promote science and science education through a wide range of activities. It has defined four major program areas: :* Recognition of outstanding contributions to science :* Education and public awareness :* Science policy :* International relations The academy also runs the 22 National Committees for Science which provide a forum to discuss issues relevant to all the scientific disciplines in Australia. Origins The Australian National Research Council (ANRC) was established in 1919 for the purpose of representing Australia on the In ...

Antarctic Specially Protected Area
An Antarctic Specially Protected Area (ASPA) is an area on the continent of Antarctica, or on nearby islands, which is protected by scientists and several different international bodies. The protected areas were established in 1961 under the Antarctic Treaty System, which governs all the land and water south of 60 latitude and protects against human development. A permit is required for entry into any ASPA site. The ASPA sites are protected by the governments of Australia, New Zealand, United States, United Kingdom, Chile, France, Argentina, Poland, Russia, Norway, Japan, India, Italy, and Republic of Korea. There are currently 72 sites. List of ASPA sites See also *Antarctic Specially Managed Area An Antarctic Specially Managed Area (ASMA) is a protected area on the continent of Antarctica, or on its adjacent islands.

Last Glacial Maximum
The Last Glacial Maximum (LGM), also referred to as the Late Glacial Maximum, was the most recent time during the Last Glacial Period that ice sheets were at their greatest extent. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing drought, desertification, and a large drop in sea levels. Based on changes in position of ice sheet margins dated via terrestrial cosmogenic nuclides and radiocarbon dating, growth of ice sheets commenced 33,000 years ago and maximum coverage was between 26,500 years and 19–20,000 years ago, when deglaciation commenced in the Northern Hemisphere, causing an abrupt rise in sea level. Decline of the West Antarctica ice sheet occurred between 14,000 and 15,000 years ago, consistent with evidence for another abrupt rise in the sea level about 14,500 years ago. Glacier fluctuations around the Strait of Magellan suggest the peak in glacial surface area was constrained to betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effects Of Climate Change
The effects of climate change impact the physical environment, ecosystems and human societies. The environmental effects of climate change are broad and far-reaching. They affect the water cycle, oceans, sea and land ice (glaciers), sea level, as well as weather and climate extreme events. The changes in climate are not uniform across the Earth. In particular, most land areas have warmed faster than most ocean areas, and the Arctic is warming faster than most other regions. The regional changes vary: at high latitudes it is the average temperature that is increasing, while for the oceans and tropics it is in particular the rainfall and the water cycle where changes are observed. The magnitude of future impacts of climate change can be reduced by climate change mitigation and adaptation. Climate change has degraded land by raising temperatures, drying soils and increasing wildfire risk. Recent warming has strongly affected natural biological systems. Species worldwide are mig ...

Palynology
Palynology is the "study of dust" (from grc-gre, παλύνω, palynō, "strew, sprinkle" and '' -logy'') or of "particles that are strewn". A classic palynologist analyses particulate samples collected from the air, from water, or from deposits including sediments of any age. The condition and identification of those particles, organic and inorganic, give the palynologist clues to the life, environment, and energetic conditions that produced them. The term is commonly used to refer to a subset of the discipline, which is defined as "the study of microscopic objects of macromolecular organic composition (i.e., compounds of carbon, hydrogen, nitrogen and oxygen), not capable of dissolution in hydrochloric or hydrofluoric acids". It is the science that studies contemporary and fossil palynomorphs (paleopalynology), including pollen, spores, orbicules, dinocysts, acritarchs, chitinozoans and scolecodonts, together with particulate organic matter (POM) and kerogen found in sedimen ...

Geomorphology
Geomorphology (from Ancient Greek: , ', "earth"; , ', "form"; and , ', "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field. Overview Earth's surface is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography. Surface processes co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
