A. G. Nathorst
Alfred Gabriel Nathorst (7 November 1850 – 20 January 1921) was a Swedish Arctic explorer, geologist, and palaeobotanist. He travelled to Spitzbergen, Svalbard and Greenland where he took an interest in the Arctic floras from the Paleozoic and Mesozoic periods. Life Nathorst was born in Väderbrunn in Sweden to Hjalmar Otto and Maria Charlotta born Georgii, who had moved to Alnarp where Hjalmar served as a professor at the institute of agriculture. Nathorst studied at Malmö before joining the University of Lund in 1868. He spent some time in the University of Uppsala and returned to Lund for his doctorate in 1874. His interest in botany were influenced by N. P. Angelin. Nathorst's interest in geology was awakened by Charles Lyell's ''Principles of Geology'' and, at the age of 21, Nathorst visited Lyell in England in 1872. Nathorst was employed at the Geological Survey of Sweden in 1873–84. He was then appointed professor, by royal decree on the 5 December 1884, and was ...

Antarctic Sound, Greenland
The Antarctic Sound () is a sound in King Christian X Land, Northeast Greenland. Administratively it is part of the Northeast Greenland National Park zone. History The sound was named by Alfred Gabriel Nathorst after his ship ''Antarctic'',''Catalogue of place names in northern East Greenland'', Geological Survey of Denmark and Greenland on which he found and first mapped this fjord branch in 1899 during the Swedish Greenland Expedition in search of survivors of S. A. Andrée's Arctic balloon expedition of 1897.Spencer Apollonio, ''Lands That Hold One Spellbound: A Story of East Greenland,'' 2008, p. 81 Geography It is a fjord forming a channel that runs roughly from northwest to southeast between the southern shore of mid Kaiser Franz Joseph Fjord to the north and the head of King Oscar Fjord to the south. Its minimum width is 3 km. The Antarctic Sound separates the northeastern shore of Suess Land —part of the Greenland mainland— from the southwestern shore of Ymer ...

Eugen Warming
Johannes Eugenius Bülow Warming (3 November 1841 – 2 April 1924), known as Eugen Warming, was a Danish botanist and a main founding figure of the scientific discipline of ecology. Warming wrote the first textbook (1895) on plant ecology, taught the first university course in ecology and gave the concept its meaning and content. Scholar R. J. Goodland wrote in 1975: “''If one individual can be singled out to be honoured as the founder of ecology, Warming should gain precedence''”. Warming wrote a number of textbooks on botany, plant geography and ecology, which were translated to several languages and were immensely influential at their time and later. Most important were '' Plantesamfund'' and ''Haandbog i den systematiske Botanik''. Early life and family life Warming was born on the small Wadden Sea island of Mandø as the only child of Jens Warming (1797–1844), parish minister, and Anna Marie von Bülow af Plüskow (1801–1863). After the early death of his fathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeobotany
Paleobotany or palaeobotany, also known as paleophytology, is the branch of botany dealing with the recovery and identification of plant fossils from geology, geological contexts, and their use for the biological reconstruction of past environments (palaeogeography, paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general. It is a component of paleontology and paleobiology. The prefix ''palaeo-'' or ''paleo-'' means "ancient, old", and is derived from the Ancient Greek, Greek adjective , . Paleobotany includes the study of embryophyte, land plants, as well as the study of Prehistory, prehistoric marine photoautotrophs such as photosynthetic algae, seaweeds or kelp. A closely related field is palynology, which is the study of fossilized and extant taxon, extant spores and pollen. Paleobotany is important in the reconstruction of ancient ecological and climate systems, known as paleoecology and paleoclimatology respectively. It ...

Tertiary Period
The Tertiary ( ) is an obsolete Period (geology), geologic period spanning 66 million to 2.6 or 1.8 million years ago. The period began with the extinction of the non-bird, avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic, Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene, Pliocene Epoch. The Tertiary has not been recognised by the International Commission on Stratigraphy (ICS) since the late 1980s, with the timespan of the Tertiary now being split in to the earlier Paleogene and the more recent Neogene periods, though the Tertiary continues to be used in some scientific publications. Historical use of the term The term Tertiary was first used by Giovanni Arduino (geologist), Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, t ...

Arctic
The Arctic (; . ) is the polar regions of Earth, polar region of Earth that surrounds the North Pole, lying within the Arctic Circle. The Arctic region, from the IERS Reference Meridian travelling east, consists of parts of northern Norway (Nordland, Troms, Finnmark, Svalbard and Jan Mayen), northernmost Sweden (Västerbotten, Norrbotten and Lapland (Sweden), Lappland), northern Finland (North Ostrobothnia, Kainuu and Lapland (Finland), Lappi), Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), the United States (Alaska), Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), and northern Iceland (Grímsey and Kolbeinsey), along with the Arctic Ocean and adjacent seas. Land within the Arctic region has seasonally varying cryosphere, snow and ice cover, with predominantly treeless permafrost under the tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesozoic
The Mesozoic Era is the Era (geology), era of Earth's Geologic time scale, geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Period (geology), Periods. It is characterized by the dominance of archosaurian reptiles such as the dinosaurs, and of Gymnosperm, gymnosperms such as cycads, ginkgoaceae and Araucariaceae, araucarian conifers; a hot Greenhouse and icehouse earth, greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, plesiosaurs. The Mesozoic was a time of significant tectonic, climatic, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeozoic
The Paleozoic ( , , ; or Palaeozoic) Era is the first of three geological eras of the Phanerozoic Eon. Beginning 538.8 million years ago (Ma), it succeeds the Neoproterozoic (the last era of the Proterozoic Eon) and ends 251.9 Ma at the start of the Mesozoic Era. The Paleozoic is subdivided into six geologic periods (from oldest to youngest), Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian. Some geological timescales divide the Paleozoic informally into early and late sub-eras: the Early Paleozoic consisting of the Cambrian, Ordovician and Silurian; the Late Paleozoic consisting of the Devonian, Carboniferous and Permian. The name ''Paleozoic'' was first used by Adam Sedgwick (1785–1873) in 1838 to describe the Cambrian and Ordovician periods. It was redefined by John Phillips (1800–1874) in 1840 to cover the Cambrian to Permian periods. It is derived from the Greek ''palaiós'' (παλαιός, "old") and ''zōḗ'' (ζωή, "life") meaning "ancient l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Era
The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardised international units of geological time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define ...

Scania
Scania ( ), also known by its native name of Skåne (), is the southernmost of the historical provinces of Sweden, provinces () of Sweden. Located in the south tip of the geographical region of Götaland, the province is roughly conterminous with Skåne County, created in 1997. Like the other historical provinces of Sweden, Scania still features in colloquial speech and in cultural references, and can therefore not be regarded as an archaic concept. Within Scania there are 33 municipalities of Sweden, municipalities that are autonomous within the Skåne Regional Council. Scania's largest urban areas of Sweden, city, Malmö, is the third-largest city in Sweden, as well as the fifth-largest in Scandinavia. To the north, Scania borders the historical provinces of Halland and Småland, to the northeast Blekinge, to the east and south the Baltic Sea, and to the west Öresund. Since 2000, a road and railway bridge, the Öresund Bridge, bridges the Öresund, Sound and connects Scania ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
