Polar Geospatial Center
The Polar Geospatial Center is a research center at the University of Minnesota's College of Science and Engineering funded by the National Science Foundation's Office of Polar Programs. Founded in 2007, the Polar Geospatial Center "provides geospatial support, mapping, and GIS/remote sensing solutions to researchers and logistics groups in the polar science community." It is currently directed by Paul Morin. History The Polar Geospatial Center (PGC) was founded in 2007 and was originally called the Antarctic Geospatial Information Center (AGIC). In its early days, the AGIC's goal was to provide basic mapping and GIS services for the United States Antarctic Program (USAP), and was only a two-man project. As time went on, the program's credibility and size expanded. By 2010, the program had over a half dozen team members. In March 2011, the program was "classified as a National Science Foundation cooperative agreement" and adapted to take responsibility for Arctic The Ar ...

Grigore Cobălcescu
Grigore Cobălcescu (September 22, 1831 – May 21, 1892) was a Moldavian, later Romanian geologist and paleontologist who is credited with introducing both fields into his country. Born in Iași, he graduated from the local Engineering and Architecture School in 1850. From that time until 1860, he taught at the city's high schools and actively promoted practical scientific education. From 1859 to 1862, he attended the University of Paris on a state scholarship, and returned with a degree in natural sciences. In January 1864, he became a professor at the University of Iași, in the philosophy faculty's physiology and geology department; he had begun teaching a course on natural sciences there in April 1862, as a volunteer. He remained a professor at the university until his death, and was dean of the sciences faculty from 1867 to 1870. He was also involved in social and political life, and became Senator for the university in 1872. He was one of the few who protested against the ...

Emil Racoviță
Emil Gheorghe Racoviță (; 15 November 1868 – 19 November 1947) was a Romanian biologist, zoologist, speleologist, and Antarctic explorer. Together with Grigore Antipa, he was one of the most noted promoters of natural sciences in Romania. Racoviță was the first Romanian to have gone on a scientific research expedition to the Antarctic. He was an influential professor, scholar and researcher, and served as President of the Romanian Academy from 1926 to 1929. Early life Born in Iași, he grew up on a family estate, in Șurănești, Vaslui County, he started his education in Iași, where he had Ion Creangă as a teacher, and continued his secondary education at the ''Institutele Unite'', a private high school for boys in Iași, taking his baccalauréat in 1886. He then studied law at the University of Paris, obtaining a law degree in 1889. But he did not pursue a law career, instead turning to the natural sciences. His mentor was zoologist and biologist Henri de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopard Seal
The leopard seal (''Hydrurga leptonyx''), also referred to as the sea leopard, is the second largest species of seal in the Antarctic (after the southern elephant seal). It is a top order predator, feeding on a wide range of prey including cephalopods, other pinnipeds, krill, fish, and birds, particularly penguins, and its only natural predator being the orca. It is the only species in the genus ''Hydrurga''. Its closest relatives are the Ross seal, the crabeater seal and the Weddell seal, which are all Antarctic seals of the tribe Lobodontini. Research history and taxonomy Henri Marie Ducrotay de Blainville, a French zoologist, described the leopard seal in 1820 from a stuffed specimen from the collection of one M. Hauville, in Le Havre. The skin that produced this work of taxidermy was sourced from "the southern seas", that he ascertained to be from around the Falkland Islands. Blainville describes the specimen as "beautiful", 7-8 "pieds" long ( long) and elongated, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crabeater Seal
The crabeater seal (''Lobodon carcinophaga''), also known as the krill-eater seal, is a true seal with a circumpolar distribution around the coast of Antarctica. They are the only member of the genus ''Lobodon''. They are medium- to large-sized (over 2 m in length), relatively slender and pale-colored, found primarily on the free-floating pack ice that extends seasonally out from the Antarctic coast, which they use as a platform for resting, mating, social aggregation and accessing their prey. They are by far the most abundant seal species in the world. While population estimates are uncertain, there are at least 7 million and possibly as many as 75 million individuals. This success of this species is due to its specialized predation on the abundant Antarctic krill of the Southern Ocean, for which it has uniquely adapted, sieve-like tooth structure. Indeed, its scientific name, translated as "lobe-toothed (''lobodon'') crab eater (''carcinophaga'')", refers specifically ...
