Port Lockroy
Port Lockroy is a bay forming a natural harbour on the north-western shore of Wiencke Island in the Palmer Archipelago to the west of the Antarctic Peninsula. The Antarctic base with the same name, situated on Goudier Island in this bay, includes the most southerly operational post office in the world. The base was left unstaffed from 2020 to 2022 due to the COVID-19 pandemic, though the museum house remained open to individual visits. On 4 October 2022 it was announced that a team of 4 women had been chosen to return to open the base for the summer 2022/23 season. History The bay was discovered in 1904 and named after Edouard Lockroy, a French politician and Vice President of the Chamber of Deputies, who assisted Jean-Baptiste Charcot in obtaining government funding for his French Antarctic Expedition. The harbour was used for whaling between 1911 and 1931. During World War II, the British military Operation Tabarin established the Port Lockroy Station A on tiny Goudier Is ...

Port Lockroy 1962
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhou ...

British Antarctic Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the British Admiralty, Admiralty and the Secretary of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alice Creek
Alice Creek () is a cove forming the southernmost portion of Port Lockroy, Wiencke Island, in the Palmer Archipelago of Antarctica. It was discovered by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, and named by him for the wife of Édouard Lockroy, Vice President of the French Chamber of Deputies Chamber of Deputies (french: Chambre des députés) was a parliamentary body in France in the nineteenth and twentieth centuries: * 1814–1848 during the Bourbon Restoration and the July Monarchy, the Chamber of Deputies was the lower house o ... who assisted Charcot in obtaining government support for the expedition. The most outstanding local feature is known as Knife Edge Ridge, bounding the western edge of Alice Creek, and forms the point where the glacier turns into the inner harbour region of Port Lockroy. Being composed of ice and snow, this feature changes shape and position from time to time, meaning no accurate position may be recorded. It is f ...

Historic Sites And Monuments In Antarctica
A Historic Site or Monument (HSM) is a protected location of historic interest on the continent of Antarctica, or on its adjacent islands. The list of historic sites was first drawn up in 1972,Recommendation ATCM VII-9 (Wellington, 1972) and has since expanded to cover 95 sites, with the most recent listed in 2021. Five sites have been removed from the list for various reasons. Historic Sites and Monuments are protected under the Antarctic Treaty System, as one of three classes of Antarctic Protected Areas.

International Geophysical Year
The International Geophysical Year (IGY; french: Année géophysique internationale) was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific interchange between East and West had been seriously interrupted. Sixty-seven countries participated in IGY projects, although one notable exception was the mainland People's Republic of China, which was protesting against the participation of the Republic of China ( Taiwan). East and West agreed to nominate the Belgian Marcel Nicolet as secretary general of the associated international organization. The IGY encompassed eleven Earth sciences: aurora and airglow, cosmic rays, geomagnetism, gravity, ionospheric physics, longitude and latitude determinations (precision mapping), meteorology, oceanography, seismology, and solar activity. The timing of the IGY was particularly suited for studying some of these phenomena, since it cove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auroral Chorus
An auroral chorus is a series of electromagnetic waves at frequencies which resemble chirps, whistles, and quasi-musical sounds in predominantly rising tones when played as pressure waves (sound), which are created by geomagnetic storms also responsible for the auroras. The sounds last approximately 0.1 to 1.0 seconds. Other auroral sounds includes hissing, swishing, rustling and cracking. The electromagnetic waves are a type of natural radio waves, vibrations of electric and magnetic energy occurring at the same frequency as sound. Detection Auroral chorus can be detected primarily around the magnetic equator, specifically in two distinct frequency bands, one above the equatorial half gyro-frequency and one below it. The gyro-frequency ranges from 0.6 kHz to about 1.6 kHz. Distinguishable on high resolution wideband spectrographs, the wave amplitude grows linearly then switches to non-linear. Demonstrating a peak distribution near dawn, the auroral chorus is most dete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ionosphere
The ionosphere () is the ionized part of the upper atmosphere of Earth, from about to above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on Earth. History of discovery As early as 1839, the German mathematician and physicist Carl Friedrich Gauss postulated that an electrically conducting region of the atmosphere could account for observed variations of Earth's magnetic field. Sixty years later, Guglielmo Marconi received the first trans-Atlantic radio signal on December 12, 1901, in St. John's, Newfoundland (now in Canada) using a kite-supported antenna for reception. The transmitting station in Poldhu, Cornwall, used a spark-gap transmitter to produce a signal with a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passport Stamp
A passport stamp is an inked impression in a passport typically made by rubber stamp upon entering or exiting a territory. Passport stamps may occasionally take the form of sticker stamps, such as entry stamps from Japan. Depending on nationality, a visitor may not receive a stamp at all (unless specifically requested), such as an EU or EFTA citizen travelling to an EU or EFTA country, Albania,https://www.parlament.al/wp-content/uploads/2015/10/ligj-71.pdf or North Macedonia.http://www.mvr.gov.mk/Upload/Documents/ZAKON%20ZA%20GRANI%5ENA%20KONTROLA.pdf Most countries issue exit stamps in addition to entry stamps. A few countries issue only entry stamps, including Canada, El Salvador, Ireland, New Zealand, the United Kingdom and the United States. Argentina, Australia, Hong Kong, Israel, Macau, Singapore and South Korea do not stamp passports upon entry nor exit. These countries or regions issue landing slips instead, with the exception of Australia who do not issue any form of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
