Palmer Station
Palmer Station is a United States research station in Antarctica located on Anvers island (aka Antwerp Island), the only U.S. station on the continent located north of the Antarctic Circle. The first Palmer was built in 1965, but the current site, near to the older one, had its initial construction of the station finished in 1968. The station, like the other U.S. Antarctic stations, is operated by the United States Antarctic Program (USAP) of the National Science Foundation. The base is much smaller than McMurdo, with about 40 staff, and is focused on marine and biology research such as seabirds and plankton. It also supports the RN73 site for atmospheric monitoring for radionuclides. The base is about as distant from the equator as Fairbanks, Alaska in the northern hemisphere, whereas Palmer is in the southern hemisphere. Under the Antarctica Treaty System established in 1958, the base is neither a claim nor a forfeiture of the right to do so. There are several old claims in t ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual Climate of Antarctica#Precipitation, precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the Lowest temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Torgersen Island
Torgersen Island is a small rocky island lying just east of Litchfield Island in the entrance to Arthur Harbour, off the south-west coast of Anvers Island Anvers Island or Antwerp Island or Antwerpen Island or Isla Amberes is a high, mountainous island long, the largest in the Palmer Archipelago of Antarctica. It was discovered by John Biscoe in 1832 and named in 1898 by the Belgian Antarctic Expe ... in the Palmer Archipelago of Antarctica. It was surveyed by the Falkland Islands Dependencies Survey in 1955 and named by the UK-APC for Torstein Torgersen, first mate of the ''Harbor'' in late February 1955, preceding the vessel in one of the ship's boats and making soundings. Birds The island formed part of the Northern Arthur Harbour Important Bird Area (IBA) number 013, identified as such by BirdLife International because it supports significant seabird bird colony, breeding colonies. The Arthur Harbour IBA was delisted in 2015. See also * List of Antarctic and subantar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lightning
Lightning is a natural phenomenon consisting of electrostatic discharges occurring through the atmosphere between two electrically charged regions. One or both regions are within the atmosphere, with the second region sometimes occurring on the land, ground. Following the lightning, the regions become partially or wholly electrically neutralized. Lightning involves a near-instantaneous release of energy on a scale averaging between 200 megajoules and 7 gigajoules. The air around the lightning flash rapidly heats to temperatures of about . There is an emission of electromagnetic radiation across a wide range of wavelengths, some visible as a bright flash. Lightning also causes thunder, a sound from the shock wave which develops as heated gases in the vicinity of the discharge experience a sudden increase in pressure. The most common occurrence of a lightning event is known as a thunderstorm, though they can also commonly occur in other types of energetic weather systems, such ...

Radio Receiver
In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves of radio frequency) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation. Radio receivers are essential components of all systems based on radio technology. The information produced by the receiver may be in the form of sound, video (television), or digital data. A radio receiver may be a separate piece of electronic equ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heliophysics
Heliophysics (from the prefix "wikt:helio-, helio", from Attic Greek ''hḗlios'', meaning Sun, and the noun "physics": the science of matter and energy and their interactions) is the physics of the Sun and its connection with the Solar System. NASA defines heliophysics as "(1) the comprehensive new term for the science of the Sun - Solar System Connection, (2) the exploration, discovery, and understanding of Earth's space environment, and (3) the system science that unites all of the linked phenomena in the region of the cosmos influenced by a star like Sun, our Sun." Heliophysics is broader than Solar physics, that studies the Sun itself, including its interior, atmosphere, and magnetic fields. It concentrates on the Sun's effects on Earth and other bodies within the Solar System, as well as the changing conditions in space. It is primarily concerned with the magnetosphere, ionosphere, thermosphere, mesosphere, and upper atmosphere of the Earth and other planets. Heliophysics ...

Seismic
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies. It also includes studies of the environmental effects of earthquakes such as tsunamis; other seismic sources such as volcanoes, plate tectonics, glaciers, rivers, oceanic microseisms, and the atmosphere; and artificial processes such as explosions. Paleoseismology is a related field that uses geology to infer information regarding past earthquakes. A recording of Earth's motion as a function of time, created by a seismograph is called a seismogram. A seismologist is a scientist who works in basic or applied seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus () ...

Marine Biology
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many scientific classification, phyla, family (biology), families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment (biophysical), environment rather than on taxonomy (biology), taxonomy. A large proportion of all life, life on Earth lives in the ocean. The exact size of this "large proportion" is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world, covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean.

Quotation marks are punctuation marks used in pairs in various writing systems to identify direct speech, a quotation, or a phrase. The pair consists of an opening quotation mark and a closing quotation mark, which may or may not be the same glyph. Quotation marks have a variety of forms in different languages and in different media. History The single quotation mark is traced to Ancient Greek practice, adopted and adapted by monastic copyists. Isidore of Seville, in his seventh century encyclopedia, , described their use of the Greek ''diplé'' (a chevron): The double quotation mark derives from a marginal notation used in fifteenth-century manuscript annotations to indicate a passage of particular importance (not necessarily a quotation); the notation was placed in the outside margin of the page and was repeated alongside each line of the passage. In his edition of the works of Aristotle, which appeared in 1483 or 1484, the Milanese Renaissance humanist Francesco Fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drake Passage
The Drake Passage is the body of water between South America's Cape Horn, Chile, Argentina, and the South Shetland Islands of Antarctica. It connects the southwestern part of the Atlantic Ocean (Scotia Sea) with the southeastern part of the Pacific Ocean and extends into the Southern Ocean. The passage is named after the 16th-century English explorer and privateer Sir Francis Drake. The Drake Passage is considered one of the most treacherous voyages for ships to make. The Antarctic Circumpolar Current, which runs through it, meets no resistance from any landmass, and waves top , giving it a reputation for being "the most powerful convergence of seas". As the Drake Passage is the narrowest passage (choke point) around Antarctica, its existence and shape strongly influence the circulation of water around Antarctica and the global oceanic circulation, as well as the global climate. The bathymetry of the Drake Passage plays an important role in the global mixing of oceanic water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orange, California
Orange is a city located in northern Orange County, California, United States. It is approximately north of the county seat, Santa Ana, California, Santa Ana. Orange is unusual in this region because many of the homes in its Old Town District were built before 1920. While many other cities in the region demolished such houses in the 1960s, Orange decided to preserve them. The small city of Villa Park, California, Villa Park is surrounded by the city of Orange. The population of Orange was 139,911 as of 2020 United States census, 2020. History Members of the Tongva and Juaneño/Luiseño ethnic group long inhabited this area. After the 1769 expedition of Gaspar de Portolá, an expedition out of San Blas, Nayarit, Mexico, led by Father Junípero Serra, named the area Vallejo de Santa Ana (Valley of Saint Anne). On November 1, 1776, Mission San Juan Capistrano became the area's first permanent European settlement in Alta California, New Spain. In 1801, the Spanish Empire grante ...
