Kirkby Shoal
Kirkby Shoal is a small shoal area with depths of less than extending about westwards and south-southwestwards, about from the summit of Shirley Island, Windmill Islands, and northwest of Stonehocker Point, Clark Peninsula. Discovery and naming Kirkby Shoal was discovered and charted in 1962 during a hydrographic survey of Newcomb Bay and approaches by d'A.T. Gale, hydrographic surveyor with the Australian National Antarctic Research Expedition (ANARE) on the ''Thala Dan'', led by Phillip Law. It was named by the Antarctic Names Committee of Australia after Sydney L. Kirkby, a surveyor at Mawson Station in 1956 and 1960.

Submerged Bank
An ocean bank, sometimes referred to as a fishing bank or simply bank, is a part of the seabed that is shallow compared to its surrounding area, such as a shoal or the top of an underwater hill. Somewhat like continental slopes, ocean bank slopes can upwell as tidal and other flows intercept them, sometimes resulting in nutrient-rich currents. Because of this, some large banks, such as Dogger Bank and the Grand Banks of Newfoundland, are among the richest fishing grounds in the world. There are some banks that were reported in the 19th century by navigators, such as Wachusett Reef, whose existence is doubtful. Types Ocean banks may be of volcanic nature. Banks may be carbonate or terrigenous. In tropical areas some banks are submerged atolls. As they are not associated with any landmass, banks have no outside source of sediments. Carbonate banks are typically platforms, rising from the ocean depths, whereas terrigenous banks are elevated sedimentary deposits. Seamounts, by ...

Phillip Law
Phillip Garth Law, AC, CBE, FAA, FTSE (21 April 1912 – 28 February 2010) was an Australian scientist and explorer who served as director of Australian National Antarctic Research Expeditions (ANARE) from 1949 to 1966. Early life Law was born in Tallangatta, Victoria, the second of six children of Arthur and Lily Law. One of his younger sisters was the traveller and writer Wendy Law Suart. After attending Hamilton High School, he taught in secondary schools, including Melbourne High School where he taught physics and boxing, while studying part-time at the University of Melbourne, earning an MSc in 1941. He was the Melbourne University lightweight boxing champion and also lectured in physics there from 1943 to 1948. During the Second World War he enlisted in the RAAF, though the university physics department, which was involved in weapons research, insisted that he continue his work there. He did however manage to visit the battle areas of New Guinea on a four-month scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of The Southern Ocean
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 the fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoals Of Antarctica
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar or quite different from how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, this term refers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Antarctica
The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term ''Antarctic'', referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD. The rounding of the Cape of Good Hope and Cape Horn in the 15th and 16th centuries proved that ''Terra Australis Incognita'' ("Unknown Southern Land"), if it existed, was a continent in its own right. In 1773, James Cook and his crew crossed the Antarctic Circle for the first time; however, although they discovered nearby islands, they did not catch sight of Antarctica itself. It is believed he was as close as from the mainland. On 27 January 1820, a Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev discovered an ice shelf at Princess Martha Coast that later became known as the Fimbul Ice Shelf. Bellingshausen and Lazarev became the first explorers to see and officially d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mawson Station
The Mawson Station, commonly called Mawson, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Mawson lies in Holme Bay in Mac. Robertson Land, East Antarctica in the Australian Antarctic Territory, a territory claimed by Australia. Established in 1954, Mawson is Australia's oldest Antarctic station and the oldest continuously inhabited Antarctic station south of the Antarctic Circle. Mawson was named in honour of the Australian Antarctic explorer Sir Douglas Mawson. Mawson was listed on the Register of the National Estate in 2001 and listed on the Commonwealth Heritage List on 22 June 2004, reflecting the post-World War Two revival of Australia's scientific research and territorial interests in Antarctica. Purpose Mawson Station is a base for scientific research programs including an underground cosmic ray detector, various long-term meteorological aeronomy and geomagnetic studies, as well as ongoing cons ...

Southern Ocean
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of , it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean. Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Ocean's northern boundary or even existence, considering the waters as various parts of the Pacific, Atlantic, and Indian oceans, instead. However, according to Commodore John Leech of the International Hydrographic Organization (IHO), recent oceanographic research has discovered the importance of Southern ...

Australian National Antarctic Research Expedition
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in south polar regions since as early as Douglas Mawson's Australasian Antarctic Expedition in 1911. Further Australian exploration of the Antarctic continent was conducted during the British Australian and New Zealand Antarctic Research Expedition (BANZARE), which was conducted over the years 1929–1931. The Australian National Antarctic Research Expeditions were established in 1947 with expeditions to Macquarie Island and Heard Island. In 1948 the Australian Antarctic Division (AAD) was established to administer the expedition program. ANARE Name The name ANARE fell out of official use in the early 2000s. However current and former Australian Antarctic expeditioners continue to use the term informally as a means of identifica ...
