Ealey Glacier
Ealey Glacier () is a glacier, flowing northeast from the lower slopes of the Big Ben massif to the northeast side of Heard Island in the southern Indian Ocean. Its terminus is located close southeast of Cape Bidlingmaier, between Melbourne Bluff and North Barrier. The glacier terminates in ice cliffs. To the southeast of Ealey Glacier is Compton Glacier, whose terminus is located at Compton Lagoon, between Gilchrist Beach and Fairchild Beach. To the west of Ealey Glacier is Downes Glacier, whose terminus is located at Mechanics Bay, between Saddle Point and Cape Bidlingmaier. Discovery and naming Ealey Glacier is named after E. H. M. "Tim" Ealey, biologist on the 1949 ANARE Heard Island Expedition who crossed the glacier during a biological survey en route to Spit Point Spit Point () is the east tip of the long Elephant Spit, a conspicuous spit at the eastern end of Heard Island The Territory of Heard Island and McDonald Islands (HIMI) is an Australian external ter ...

Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

ANARE
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australia: Antarctic Program#Australian Antarctic program, Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in South Pole, 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.

Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tim Ealey
Eric Herbert Mitchell "Tim" Ealey, 29 March 1927 - 21 October 2020, was an Australian biologist, known for his contributions to science, the environment and conservation awareness and was the recipient of a Medal of the Order of Australia. Ealey has received international recognition for his works, and nationally acknowledged for a program that involved schools in rehabilitation of the environment. Ealey was commemorated in the specific epithet of a tiny marsupial, '' Ningaui timealeyi'', he discovered in the Pilbara region of Western Australia. Amongst his works was research on the monotreme family of Tachyglossidae, the species of echidnas. Ealey worked for the Antarctic Division in the 1950s, researching the fauna of Heard Island.

Saddle Point
In mathematics, a saddle point or minimax point is a point on the surface of the graph of a function where the slopes (derivatives) in orthogonal directions are all zero (a critical point), but which is not a local extremum of the function. An example of a saddle point is when there is a critical point with a relative minimum along one axial direction (between peaks) and at a relative maximum along the crossing axis. However, a saddle point need not be in this form. For example, the function f(x,y) = x^2 + y^3 has a critical point at (0, 0) that is a saddle point since it is neither a relative maximum nor relative minimum, but it does not have a relative maximum or relative minimum in the y-direction. The name derives from the fact that the prototypical example in two dimensions is a surface that ''curves up'' in one direction, and ''curves down'' in a different direction, resembling a riding saddle or a mountain pass between two peaks forming a landform saddle.

Downes Glacier
Downes Glacier () is a broad tidewater glacier on the north side of Heard Island in the southern Indian Ocean. It flows north on both sides of Cape Bidlingmaier to the north coast of Heard Island. To the east of Downes Glacier is Ealey Glacier, whose terminus is located close southeast of Cape Bidlingmaier.

Fairchild Beach
Fairchild Beach () is a sandy beach, wide and long, which extends north from the base of Round Hill to the south side of the terminus of Compton Glacier, on the east side of Heard Island in the southern Indian Ocean. The beach faces Compton Lagoon, and at its western edge communicates with the rocky Gilchrist Beach. To the south of Fairchild Beach is Brown Glacier, whose terminus is located at Brown Lagoon. The name "Fairchild's Beach" was in use by American sealers Sealer may refer either to a person or ship engaged in seal hunting, or to a sealant; associated terms include: Seal hunting * Sealer Hill, South Shetland Islands, Antarctica * Sealers' Oven, bread oven of mud and stone built by sealers around 180 ... as early as 1857, but the origin of the name is not known.

Gilchrist Beach
Gilchrist Beach () is a rocky beach, 1 nautical mile (1.9 km) long, lying west of Compton Glacier on the north side of Heard Island. At its eastern edge, Gilchrist Beach communicates with the sandy Fairchild Beach. Travelling eastwards from Gilchrist Beach to Fairchild Beach, one arrives at the base of Round Hill. This feature was known to American sealers as Rocky Beach as early as 1857, as shown by an unpublished sealer's map of "Hurds Island" compiled during the 1860–1870 period. The name Stoney Beach was also in use during this period. The name Gilchrist Beach, as applied by the ANARE ( Australian National Antarctic Research Expeditions) during its 1948 survey of the island An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water.
