Ice Cap
In glaciology, an ice cap is a mass of ice that covers less than of land area (usually covering a highland area). Larger ice masses covering more than are termed ice sheets. Description Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains). By contrast, ice masses of similar size that ''are'' constrained by topographical features are known as ice fields. The ''dome'' of an ice cap is usually centred on the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery. Ice caps have significant effects on the geomorphology of the area that they occupy. Plastic moulding, gouging and other glacial erosional features become present upon the glacier's retreat. Many lakes, such as the Great Lakes in North America, as well as numerous valleys have been formed by glacial action over hundreds of thousands of years. On Earth, there are about of total ice mass.

Stoneley Point
Ulu Peninsula () is that portion of James Ross Island northwest of the narrow neck of land between Rohss Bay and Croft Bay, extending from Cape Obelisk to Cape Lachman. Named descriptively by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1987. In plan view the cove is shaped like an ulu, a type of knife A knife ( : knives; from Old Norse 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced ... traditionally used by Inuit women.

James Ross Island
James Ross Island is a large island off the southeast side and near the northeastern extremity of the Antarctic Peninsula, from which it is separated by Prince Gustav Channel. Rising to , it is irregularly shaped and extends in a north–south direction. It was charted in October 1903 by the Swedish Antarctic Expedition under Otto Nordenskiöld, who named it for Sir James Clark Ross, the leader of a British expedition to this area in 1842 that discovered and roughly charted a number of points along the eastern side of the island. The style, "James" Ross Island is used to avoid confusion with the more widely known Ross Island in McMurdo Sound. It is one of several islands around the peninsula known as Graham Land, which is closer to South America than any other part of that continent. The island was connected to the Antarctic mainland by an ice shelf until 1995, when the ice shelf collapsed, making the Prince Gustav Channel passable for the first time. Mendel Polar Station, t ...

UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by Scientific Committee on Antarctic Research, SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica.

Gwion Davies
Taliesin ( , ; 6th century AD) was an early Brittonic poet of Sub-Roman Britain whose work has possibly survived in a Middle Welsh manuscript, the ''Book of Taliesin''. Taliesin was a renowned bard who is believed to have sung at the courts of at least three kings. In 1960, Ifor Williams identified eleven of the medieval poems ascribed to Taliesin as possibly originating as early as the sixth century, and so possibly being composed by a historical Taliesin. The bulk of this work praises King Urien of Rheged and his son Owain mab Urien, although several of the poems indicate that Taliesin also served as court bard to King Brochfael Ysgithrog of Powys and his successor Cynan Garwyn, either before or during his time at Urien's court. Some of the events to which the poems refer, such as the Battle of Arfderydd (c. 573), are referred to in other sources. John T. Koch argues that the description of Easter in the praise poem ''Yspeil Taliesin'' ('The Spoils of Taliesin') indicates th ...

Operation Tabarin
Operation Tabarin was the code name for a secret British expedition to the Antarctic during World War Two, operational 1943–46. Conducted by the Admiralty on behalf of the Colonial Office, its primary objective was to strengthen British claims to sovereignty of the British territory of the Falkland Islands Dependencies (FID), to which Argentina and Chile had made counter claims since the outbreak of war. This was done by establishing permanently occupied bases, carrying out administrative activities such as postal services and undertaking scientific research. The meteorological observations made aided Allied shipping in the South Atlantic Ocean. Following Cabinet approval in January 1943, there was an intensive period of planning, recruitment and procurement, before the expedition left the UK in November 1943, led by Lieutenant-Commander James Marr. Two bases were established in early 1944 – firstly, Base B, at Deception Island, South Shetland Islands, and later the main base, ...

Port Lockroy
Port Lockroy is a bay forming a natural harbour on the north-western shore of Wiencke Island in the Palmer Archipelago to the west of the Antarctic Peninsula. The Antarctic base with the same name, situated on Goudier Island in this bay, includes the most southerly operational post office in the world. The base was left unstaffed from 2020 to 2022 due to the COVID-19 pandemic, though the museum house remained open to individual visits. On 4 October 2022 it was announced that a team of 4 women had been chosen to return to open the base for the summer 2022/23 season. History The bay was discovered in 1904 and named after Edouard Lockroy, a French politician and Vice President of the Chamber of Deputies, who assisted Jean-Baptiste Charcot in obtaining government funding for his French Antarctic Expedition. The harbour was used for whaling between 1911 and 1931. During World War II, the British military Operation Tabarin established the Port Lockroy Station A on tiny Goudier ...

Hope Bay
Hope Bay (Spanish: ''Bahía Esperanza'') on Trinity Peninsula, is long and wide, indenting the tip of the Antarctic Peninsula and opening on Antarctic Sound. It is the site of the Argentinian Antarctic settlement Esperanza Base, established in 1952. Important Bird Area The bay has been identified as an Important Bird Area (IBA) by BirdLife International because it supports one of the largest Adélie penguin colonies in Antarctica with around 125,000 pairs. Other birds nesting at the site include gentoo penguins, brown skuas, Antarctic terns, Wilson's storm-petrels, kelp gulls and snowy sheathbills. History The Bay was discovered on January 15, 1902 by the Swedish Antarctic Expedition under Otto Nordenskiöld, who named it in commemoration of the winter spent there by J. Gunnar Andersson and S.A. Duse, Toralf Grunden of his expedition after his ship (the '' Antarctic'') was crushed by the ice and lost. They were eventually rescued by Argentine corvette ''Uruguay''. Hop ...

Ice Caps Of Antarctica
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
