Cape Robertson
Cape Robertson is a cape which marks the west side of the entrance to Jessie Bay, in the north-west part of Laurie Island, in the South Orkney Islands of Antarctica. It lies east of Route Point at the north end of Mackenzie Peninsula. On the map of Laurie Island by the Scottish National Antarctic Expedition under Bruce, 1902–04, the name Cape Robertson appears in the position of Route Point, previously named by Captain George Powell and Captain Nathaniel Palmer in 1821. The name Route Point is retained for the north-west end of Mackenzie Peninsula; Cape Robertson is the north-east extremity. It is named for Thomas Robertson, captain of the Scotia, expedition ship of the ScotNAE. Important Bird Area Some 388 ha of the site has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a large breeding colony of about 20,000 pairs of chinstrap penguins.

Cape (geography)
In geography, a cape is a headland or a promontory of large size extending into a body of water, usually the sea.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, p. 80. . A cape usually represents a marked change in trend of the Coast, coastline, often making them important landmarks in sea navigation. This also makes them prone to natural forms of erosion, mainly tidal actions, which results in them having a relatively short geological lifespan. Capes can be formed by glaciers, volcanoes, and changes in sea level. Erosion plays a large role in each of these methods of formation.

Nathaniel Palmer
Nathaniel Brown Palmer (August 8, 1799June 21, 1877) was an American seal hunter, explorer, sailing captain, and ship designer. He gave his name to Palmer Land, Antarctica, which he explored in 1820 on his sloop ''Hero''. He was born in Stonington, Connecticut, and was a descendant of Walter Palmer, one of the town's founders. Sealing career and Antarctic exploration During the 1810s the hides of Antarctic Ocean seals were highly valued as items for trade with China. Palmer served as second mate on board s first voyage, during which she became the first American vessel known to reach the South Shetland Islands. As a skilled and fearless seal hunter, Palmer achieved his first command at the early age of 21. His vessel, a diminutive sloop named , was only in length. Palmer steered southward in ''Hero'' at the beginning of the Antarctic summer of 1820–1821. Aggressively searching for new seal rookeries south of Cape Horn, on November 17, 1820, Palmer and his men became the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headlands Of The South Orkney Islands
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a Cape (geography), cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking Wave, waves, Rocky shore, rocky shores, intense erosion, and steep sea cliffs, sea cliff. Headlands and Bay, bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as Sand, sands and Clay, clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula.

Expedition Rock
Expedition Rock () is a submerged rock east-northeast of Cape Robertson, lying in the entrance to Jessie Bay on the north side of Laurie Island, in the South Orkney Islands. It was charted by Petter Sorlle, 1912–15, and called "Aagot Gr"; it was recharted by Discovery Investigations The Discovery Investigations were a series of scientific cruises and shore-based investigations into the biology of whales in the Southern Ocean. They were funded by the British Colonial Office and organised by the Discovery Committee in London, wh ... in 1933 and named Expedition Rock.

Bird Colony
A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non- neornithine birds ( Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania. Variations on colonial nesting in birds Approximately 13% of all bird species nest colonially. Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonie ...

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

George Powell (mariner)
George Powell (1794–1824) was an English sealer, explorer and amateur naturalist. He captained three sealing expeditions to the Antarctic Ocean between 1818 and 1822. Powell was born in London. During his first expedition, in 1818 and 1819, he captained the sloop ''Dove'' and visited South Georgia and Kerguelen Islands. His second expedition, captaining ''Eliza'', lasted from 1819 until 1821, during which time he visited the Falkland Islands and the South Shetland Islands. In 1821 and 1822 he took both ''Dove'', which he captained, and ''Eliza'', captained by John Wright, on another sealing expedition to the South Shetland Islands, for which he produced a very fine chartL.

Jessie Bay
Jessie Bay () is a bay wide, lying between Mackenzie Peninsula and Pirie Peninsula, on the north side of Laurie Island in the South Orkney Islands. Apparently seen in the course of the joint cruise by Captain George Powell, a British sealer, and Captain Nathaniel Palmer, an American one. In 1821, it was roughly charted by Captain James Weddell, a British sealer. It was surveyed in 1903 by the Scottish National Antarctic Expedition of William S. Bruce, who named this bay for his wife, Jessie Mackenzie Bruce. He also named a cove in the bay, Sheila Cove, for his daughter.

Scottish National Antarctic Expedition
The Scottish National Antarctic Expedition (SNAE), 1902–1904, was organised and led by William Speirs Bruce, a natural scientist and former medical student from the University of Edinburgh. Although overshadowed in terms of prestige by Robert Falcon Scott's concurrent Discovery Expedition, the SNAE completed a full programme of exploration and scientific work. Its achievements included the establishment of a staffed meteorological station, the first in Antarctic territory, and the discovery of new land to the east of the Weddell Sea. Its large collection of biological and geological specimens, together with those from Bruce's earlier travels, led to the establishment of the Scottish Oceanographical Laboratory in 1906. Bruce had spent most of the 1890s engaged on expeditions to the Antarctic and Arctic regions, and by 1899 was Britain's most experienced polar scientist. In March of that year, he applied to join the Discovery Expedition; however, his proposal to extend that e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
