Norwegian Scientific Expedition To Tristan Da Cunha 1937-1938
The Norwegian Scientific Expedition to Tristan Da Cunha was a scientific and cultural exploration of the most remote inhabited archipelago in the world, in the south Atlantic Ocean, 2,000 kilometres (1,200 mi) from the nearest inhabited land, Saint Helena. The expedition arrived on the island in December 1937 and left in March 1938. History Captained by botanist Erling Christophersen, the thirteen man crew included three University of Oslo Ph.D. students conducting research for their dissertations, which were published shortly after their return; these included sociologist Peter A. Munch, ornithologist Yngvar Hagen, and phycologist Egil Baardseth. Also among the crew were a geologist, a marine biologist, an ichthyologist, a dentist and a doctor. A late addition to the crew was topological surveyor Allan Crawford, a British engineer who was recruited by the captain en route to Cape Town Cape Town ( af, Kaapstad; , xh, iKapa) is one of South Africa's three capital citie ...

Tristan Da Cunha
Tristan da Cunha (), colloquially Tristan, is a remote group of volcanic islands in the South Atlantic Ocean. It is the most remote inhabited archipelago in the world, lying approximately from Cape Town in South Africa, from Saint Helena and from the Falkland Islands. The territory consists of the inhabited island, Tristan da Cunha, which has a diameter of roughly and an area of ; the wildlife reserves of Gough Island and Inaccessible Island; and the smaller, uninhabited Nightingale Islands. , the main island has 250 permanent inhabitants, who all carry British Overseas Territories citizenship. The other islands are uninhabited, except for the South African personnel of a weather station on Gough Island. Tristan da Cunha is a British Overseas Territory with its own constitution. There is no airstrip on the main island; the only way of travelling in and out of Tristan is by boat, a six-day trip from South Africa. History Discovery The uninhabited islands were f ...

Phycology
Phycology () is the scientific study of algae. Also known as algology, phycology is a branch of life science. Algae are important as primary producers in aquatic ecosystems. Most algae are eukaryotic, photosynthetic organisms that live in a wet environment. They are distinguished from the higher plants by a lack of true roots, stems or leaves. They do not produce flowers. Many species are single-celled and microscopic (including phytoplankton and other microalgae); many others are multicellular to one degree or another, some of these growing to large size (for example, seaweeds such as kelp and ''Sargassum''). Phycology includes the study of prokaryotic forms known as blue-green algae or cyanobacteria. A number of microscopic algae also occur as symbionts in lichens. Phycologists typically focus on either freshwater or ocean algae, and further within those areas, either diatoms or soft algae. History of phycology While both the ancient Greeks and Romans knew of algae, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Expeditions
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek man ...

History Of Tristan Da Cunha
Tristan da Cunha is part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha and has a history going back to the beginning of the 16th century. It was settled by men from military garrisons and ships, who married native women from Saint Helena and the Cape Colony. Its people are multi-racial, descended from European male founders and mixed-race (African, Asian and European) and African women founders. Discovery The uninhabited islands of Tristan da Cunha were first sighted in May 1506 during a voyage to India by the Portuguese admiral Tristão da Cunha, although rough seas prevented a landing. He named the main island after himself, ''Ilha de Tristão da Cunha'', which was later anglicised to Tristan da Cunha Island. His discovery appeared on nautical maps from 1509 and on Mercator's world map of 1541. Some sources state that the Portuguese made the first landing on Tristan in 1520, when the ''Lás Rafael'' captained by Ruy Vaz Pereira called for wa ...

Ichthyology
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were ''hunters and gatherers'' who had learned how to obtain the most use ...
