Alec Trendall
Alec Trendall (8 December 1928 – 4 April 2013) was an English geologist, poet, and explorer. He is known for his work in mapping the island of South Georgia and for surveying the geology of Western Australia. Early life Alec Trendall was born in 1928 at Enfield, Middlesex, and in 1949 graduated in geology at London University. He has a PhD degree from Liverpool University. Exploration Trendall was the geologist on the 1951–52 and 1953-54 South Georgia Survey expeditions led by Duncan Carse. Trendall Crag, 1,005 m, overlooking the north side of Drygalski Fjord at the southeast end of South Georgia, was named to commemorate Alec Trendall's contribution. In 2011 he published a full account of the survey expeditions, entitled ''Putting South Georgia on the Map''. The Scott Polar Research Institute's digitised archive includes 305 images of Trendall including images of a bergschrund - a hole in an ice sheet - which Trendall fell down before being carried on an improvised sl ...

South Georgia Island
South Georgia ( es, Isla San Pedro) is an island in the South Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. It lies around east of the Falkland Islands. Stretching in the east–west direction, South Georgia is around long and has a maximum width of . The terrain is mountainous, with the central ridge rising to at Mount Paget. The northern coast is indented with numerous bays and fjords, serving as good harbours. Discovered by Europeans in 1675, South Georgia had no indigenous population due to its harsh climate and remoteness. Captain James Cook in made the first landing, survey and mapping of the island, and on 17 January 1775 he claimed it a British possession, naming it "Isle of Georgia" after King George III. Through its history, it served as a whaling and seal hunting base, with intermittent population scattered in several whaling bases, the most important historically being Grytviken.

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

South Georgia Survey
The South Georgia Survey was a series of expeditions to survey and map the island of South Georgia, led by Duncan Carse between 1951 and 1957. Although South Georgia had been commercially exploited as a whaling station during the first half of the 20th century, its interior was generally unknown, and maps were largely based on the original survey by James Cook, who first landed on the island in 1775. The South Georgia Survey was intended to make high-quality modern maps covering the entire island, and took place in four austral summer seasons: 1951–52, 1953–54, 1955–56, and 1956–57. The survey was funded by the Royal Geographical Society, the Falkland Islands Dependencies, Odhams Press, and other private supporters. The War Office and Ministry of Supply provided 250 man-days of cold-weather rations, along with a loan of clothing and sledging equipment. Transportation to and from South Georgia was provided on the ships used to supply the whaling stations and ferry whale o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duncan Carse
Verner Duncan Carse (28 July 1913 – 2 May 2004) was an English explorer and actor known for surveying South Georgia and for the portrayal of Special Agent Dick Barton on BBC Radio. Early life Carse was born on 28 July 1913 in Fulham, London, the son of the artist A. Duncan Carse. He attended school at Sherborne School in Dorset, England and in Lausanne, Switzerland. Carse married Bertha Sylvia Hadfield in 1938, with whom he had two daughters. He had a son with his second wife Elizabeth Wilen - Peter Carse. Carse married Venetia Kempe, his third wife, in December 1962. They lived in Fittleworth, West Sussex, and the marriage lasted until Carse's death on 2 May 2004, aged 90. Exploration Carse joined the Merchant Navy and sailed for the Southern Ocean aboard the RRS ''Discovery II'' in 1933. While in Port Stanley, Falkland Islands, Carse encountered the British Graham Land Expedition, which was on its way to Antarctica on the yacht Penola. Carse secured permission to trans ...

Drygalski Fjord
Drygalski Fjord is a bay wide which recedes northwestwards , entered immediately north of Nattriss Head along the southeast coast of South Georgia. It was charted by the Second German Antarctic Expedition, 1911–12, under Wilhelm Filchner, and named for Professor Erich von Drygalski, the leader of the First German Antarctica Expedition, 1901–03. According to L. Harrison Matthews, Drygalski Fjord might have been the place where Anthony de la Roché spent two weeks during his stay in the island in April 1675. Named locations Nattriss Head, a small but prominent rock headland, marks the south side of the entrance to Drygalski Fjord. Like the fjord, it was charted by Filchner's expedition. It was originally named Nattriss Point for E.A. Nattriss, shipping officer to the Discovery Committee, following survey by Discovery Investigations personnel in 1927. It was later renamed Nattriss Head to avoid confusion with Nattriss Point on Saunders Island in the South Sandwich Islands. ...

Bergschrund
A bergschrund (from the German for ''mountain cleft'') or rimaye (from French; ) is a crevasse that forms where moving glacier ice separates from the stagnant ice or firn above. It is often a serious obstacle for mountaineers, who sometimes abbreviate "bergschrund" to "schrund". Bergschrunds extend to the bedrock and can have a depth of well over . The bergschrund is distinct from the randkluft (also called ''rimaye''), which is the crevasse of which one face is the rock, back wall of the corrie. The randkluft arises in part from the melting of the ice due to the presence of the warmer rock face. However, the randkluft is sometimes called a bergschrund. The French word ''rimaye'' covers both notions of randkluft and bergschrund. In a corrie or cirque, the bergschrund is positioned at the rear, parallel to the back wall of the corrie. It is caused by the rotational movement of the glacier. In a longitudinal glacier, the bergschrund is at the top end of the glacier at a right angl ...

Stromatolites
Stromatolites () or stromatoliths () are layered sedimentary formations (microbialite) that are created mainly by photosynthetic microorganisms such as cyanobacteria, sulfate-reducing bacteria, and Pseudomonadota (formerly proteobacteria). These microorganisms produce adhesive compounds that cement sand and other rocky materials to form mineral "microbial mats". In turn, these mats build up layer by layer, growing gradually over time. A stromatolite may grow to a meter or more. Although they are rare today, fossilized stromatolites provide records of ancient life on Earth. Morphology Stromatolites are layered, biochemical, accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains in biofilms (specifically microbial mats), through the action of certain microbial lifeforms, especially cyanobacteria. They exhibit a variety of forms and structures, or morphologies, including conical, stratiform, domal, columnar, and branching ...

History Of South Georgia
The history of South Georgia and the South Sandwich Islands is relatively recent. When European explorers discovered the islands, they were uninhabited, and their hostile climate, mountainous terrain, and remoteness made subsequent settlement difficult. Due to these conditions, human activity in the islands has largely consisted of sealing, whaling, and scientific surveys and research, interrupted by World War II and the Falklands War. 17th to 19th century The South Atlantic island of South Georgia, situated south of the Antarctic Convergence, was the first Antarctic territory to be discovered.A concise 1982 version of the book It was first visited in 1675 by Antoine de la Roché, an English merchant born in London to a French father.L. Ivanov and N. Ivanova. Roché Island / South Georgia. In''The World of Antarctica''.Generis Publishing, 2022. pp. 68–70. He left Hamburg in 1674 as a passenger on a 350-ton vessel bound for Peru.
