Pierre Jean Édouard Desor
Pierre Jean Édouard Desor (13 February 1811, Friedrichsdorf, Grand Duchy of Hesse23 February 1882) was a German-Swiss geologist and naturalist. Biography Desor studied law at Giessen and Heidelberg, was compromised in the republican movements of 1832/3 (see, for example, Hambach Festival and Frankfurter Wachensturm), and escaped to Paris. Here his attention was drawn to geology. He made excursions with Élie de Beaumont, and in 1837 met Louis Agassiz at a meeting of naturalists in Neufchâtel. With Gressli and Vogt, Desor became an active collaborator with Agassiz, studying palaeontology and glacial phenomena, and contributing the essays for vol. iii. of Agassiz's ''Monographie d'echinodermes vivants et fossiles'' (Neufchâtel, 1842). Desor also published ''Excursions et sejours dans les glaciers et les hautes régions des Alpes de M. Agassiz et de ses compagnons de voyage'' (Neufchâtel, 1844). Together with James David Forbes, Desor ascended the Jungfrau in 1841. He was in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James David Forbes
James David Forbes (1809–1868) was a Scottish physicist and glaciologist who worked extensively on the conduction of heat and seismology. Forbes was a resident of Edinburgh for most of his life, educated at its University and a professor there from 1833 until he became principal of the United College of St Andrews in 1859. He invented an inverted pendulum seismometer in 1842. Life and work Forbes was born on 20 April 1809 at 86 George Street in Edinburgh, the fourth son of Sir William Forbes, 7th Baronet, of Monymusk and Pitsligo (1773–1828) and Williamina Belches of Invermay. His brothers were the advocate and agriculturalist Sir John Stuart Hepburn Forbes of Fettercairn and Pitsligo and the banker Charles Forbes. He entered the University of Edinburgh in 1825, and soon afterwards began to contribute papers to the ''Edinburgh Philosophical Journal'' anonymously under the signature "Δ". At the age of nineteen he became a fellow of the Royal Society of Edinbu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orography
Orography is the study of the topographic relief of mountains, and can more broadly include hills, and any part of a region's elevated terrain. Orography (also known as ''oreography'', ''orology'' or ''oreology'') falls within the broader discipline of geomorphology. The term orography comes from the Greek: , hill, , to write. Uses Mountain ranges and elevated land masses have a major impact on global climate. For instance, the elevated areas of East Africa substantially determine the strength of the Indian monsoon.Srinivasan, J., Nanjundiah, Ravi S. and Chakraborty, Arindam (2005Impact of Orography on the Simulation of Monsoon Climate in a General Circulation Model''Indian Institute of Science'' In scientific models, such as general circulation models, orography defines the lower boundary of the model over land. When a river's tributaries or settlements by the river are listed in 'orographic sequence', they are in order from the highest (nearest the source of the river) to ...

Lake Superior
Lake Superior in central North America is the largest freshwater lake in the world by surface areaThe Caspian Sea is the largest lake, but is saline, not freshwater. and the third-largest by volume, holding 10% of the world's surface fresh water. The northern and westernmost of the Great Lakes of North America, it straddles the Canada–United States border with the province of Ontario to the north and east, and the states of Minnesota to the northwest and Wisconsin and Michigan to the south. It drains into Lake Huron via St. Marys River, then through the lower Great Lakes to the St. Lawrence River and the Atlantic Ocean. Name The Ojibwe name for the lake is ''gichi-gami'' (in syllabics: , pronounced ''gitchi-gami'' or ''kitchi-gami'' in different dialects), meaning "great sea". Henry Wadsworth Longfellow wrote this name as "Gitche Gumee" in the poem '' The Song of Hiawatha'', as did Gordon Lightfoot in his song " The Wreck of the ''Edmund Fitzgerald''". Accordin ...

Henry Darwin Rogers
Henry Darwin Rogers FRS FRSE LLD (1 August 1808 – 26 May 1866) was an American geologist. His book, ''The Geology of Pennsylvania: A Government Survey'' (1858), was regarded as one of the most important publications on American geology issued up to that point. Biography Rogers was born in Philadelphia, Pennsylvania on 1 August 1808, the third of four sons of Patrick Kerr Rogers and Hannah Blythe Rogers. His parents were from Ireland, near Londonderry and emigrated to the United States where they first met and became married. Patrick Rogers was a supporter of militant efforts to end British rule in Ireland and was forced to flee to avoid persecution. Henry's middle name was given him in honour of Erasmus Darwin, of whose poem "The Botanic Garden" his father was a great admirer. In 1813 the family moved to Baltimore, Maryland, where Henry was educated in the public schools, and in 1819 they moved to Williamsburg, Virginia, where his father was professor of natural philosoph ...

John Wells Foster
John Wells Foster (March 4, 1815 – June 29, 1873) was an American geologist and archaeologist. Biography Foster was born March 4, 1815, in Petersham, Massachusetts where his father, Festus Foster was a minister. When Festus quit the ministry in 1818, the family moved to Brimfield, Massachusetts. Wells was educated locally, spent a year at Wilbraham Academy and then entered Wesleyan University in 1831.Hyde (1879) After graduating with honors in 1834, he studied law in Zanesville, Ohio and was admitted to the bar.Chicago Daily Tribune In 1837 the Ohio legislature authorized a geological survey of the state to be led by William W. Mather. Foster had studied under Mather at Wesleyan, and accepted an invitation to join the survey. Foster was assigned to a district in the central part of the state and mapped the area's basic stratigraphy. In particular he noted the area held extensive coal reserves. He also discovered the fossilized bones of mastodons and a species of giant b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Josiah D
Josiah ( or ) or Yoshiyahu; la, Iosias was the 16th king of Judah (–609 BCE) who, according to the Hebrew Bible, instituted major religious reforms by removing official worship of gods other than Yahweh. Josiah is credited by most biblical scholars with having established or compiled important Hebrew scriptures during the "Deuteronomic reform" which probably occurred during his rule. Josiah became king of the Kingdom of Judah at the age of eight, after the assassination of his father, King Amon. Josiah reigned for 31 years, from 641/640 to 610/609 BCE. Josiah is known only from biblical texts; no reference to him exists in other surviving texts of the period from Egypt or Babylon, and no clear archaeological evidence, such as inscriptions bearing his name, has ever been found. Nevertheless, most scholars believe that he existed historically and that the absence of documents is due to few documents of any sort surviving from this period, and to Jerusalem having been occupied, ...

Paleogene
The Paleogene ( ; also spelled Palaeogene or Palæogene; informally Lower Tertiary or Early Tertiary) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago (Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The earlier term Tertiary Period was used to define the span of time now covered by the Paleogene Period and subsequent Neogene Period; despite no longer being recognised as a formal stratigraphic term, 'Tertiary' is still widely found in earth science literature and remains in informal use. Paleogene is often abbreviated "Pg" (but the United States Geological Survey uses the abbreviation PE for the Paleogene on the Survey's geologic maps). During the Paleogene, mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of the Cretaceous–Paleogene extinction event that ended the preceding C ...

Stage (stratigraphy)
In chronostratigraphy, a stage is a succession of rock strata laid down in a single age on the geologic timescale, which usually represents millions of years of deposition. A given stage of rock and the corresponding age of time will by convention have the same name, and the same boundaries. Rock series are divided into stages, just as geological epochs are divided into ages. Stages can be divided into smaller stratigraphic units called chronozones. (See chart at right for full terminology hierarchy.) Stages may also be divided into substages or indeed grouped as superstages. The term faunal stage is sometimes used, referring to the fact that the same fauna (animals) are found throughout the layer (by definition). Definition Stages are primarily defined by a consistent set of fossils (biostratigraphy) or a consistent magnetic polarity (see paleomagnetism) in the rock. Usually one or more index fossils that are common, found worldwide, easily recognized, and limited to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Danian
The Danian is the oldest age or lowest stage of the Paleocene Epoch or Series, of the Paleogene Period or System, and of the Cenozoic Era or Erathem. The beginning of the Danian (and the end of the preceding Maastrichtian) is at the Cretaceous–Paleogene extinction event . The age ended , being followed by the Selandian. Stratigraphic definitions The Danian was introduced in scientific literature by German-Swiss geologist Pierre Jean Édouard Desor in 1847 following a study of fossils found in France and Denmark.Danien He identified this stage in deposits from |
Scandinavia
Scandinavia; Sámi languages: /. ( ) is a subregion in Northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. In English usage, ''Scandinavia'' most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer more narrowly to the Scandinavian Peninsula (which excludes Denmark but includes part of Finland), or more broadly to include all of Finland, Iceland, and the Faroe Islands. The geography of the region is varied, from the Norwegian fjords in the west and Scandinavian mountains covering parts of Norway and Sweden, to the low and flat areas of Denmark in the south, as well as archipelagos and lakes in the east. Most of the population in the region live in the more temperate southern regions, with the northern parts having long, cold, winters. The region became notable during the Viking Age, when Scandinavian peoples participated in large scale raiding, conquest, colonization and trading mostly throughout Eu ...

Wetterhorn
The Wetterhorn (3,692 m) is a peak in the Swiss Alps towering above the village of Grindelwald. Formerly known as Hasle Jungfrau, it is one of three summits on a mountain named the "Wetterhörner", the highest of which is the Mittelhorn (3,704 m) and the lowest and most distant the Rosenhorn (3,689 m). The latter peaks are mostly hidden from view from Grindelwald. The Grosse Scheidegg Pass crosses the col to the north, between the Wetterhorn and the Schwarzhorn. Ascents The Wetterhorn summit was first reached on August 31, 1844, by the Grindelwald guides Hans Jaun and Melchior Bannholzer, three days after they had co-guided a large party organized by the geologist Édouard Desor to the first ascent of the Rosenhorn. The Mittelhorn was first summitted on 9 July 1845 by the same guides, this time accompanied by a third, Kaspar Abplanalp, and by British climber Stanhope Templeman Speer. The son of a Scottish physician, Speer lived in Interlaken, Switzerland. A September 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
