72-491: The Patuxent Range was discovered and partially photographed on January 13, 1956 in the course of a transcontinental nonstop plane flight by personnel of U.S. Navy Operation Deep Freeze I from McMurdo Sound to Weddell Sea and return. It was named by Advisory Committee on Antarctic Names (US-ACAN) for the Naval Air Station Patuxent River (at Cedar Point, Maryland) located on the south side of

144-479: A contract period of 11 + 1 ⁄ 2 years. Weather Weather is the state of the atmosphere , describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy . On Earth , most weather phenomena occur in the lowest layer of the planet's atmosphere , the troposphere , just below the stratosphere . Weather refers to day-to-day temperature, precipitation , and other atmospheric conditions, whereas climate

216-422: A few days in advance, weather forecasters are continually working to extend this limit through meteorological research and refining current methodologies in weather prediction. However, it is theoretically impossible to make useful day-to-day predictions more than about two weeks ahead, imposing an upper limit to potential for improved prediction skill. Weather is one of the fundamental processes that shape

288-401: A given day. Since outdoor activities are severely curtailed by heavy rain , snow and the wind chill , forecasts can be used to plan activities around these events and to plan ahead to survive through them. Tropical weather forecasting is different from that at higher latitudes. The sun shines more directly on the tropics than on higher latitudes (at least on average over a year), which makes

360-658: A record of earlier exploration in Antarctica. As early as 1839, Captain Charles Wilkes led the first U.S. Naval expedition into Antarctic waters. In 1929, Admiral Richard E. Byrd established a naval base at Little America I, led an expedition to explore further inland, and conducted the first flight over the South Pole. From 1934 to 1935, the second Byrd Expedition explored much further inland and also "wintered over". The third Byrd Expedition in 1940 charted

432-523: A single jet stream near the 50th parallel north latitude, and Venus has a single jet near the equator. One of the most famous landmarks in the Solar System , Jupiter's Great Red Spot , is an anticyclonic storm known to have existed for at least 300 years. On other giant planets , the lack of a surface allows the wind to reach enormous speeds: gusts of up to 600 metres per second (about 2,100 km/h or 1,300 mph) have been measured on

504-636: A year. The actual transition to Air Guard control began in March 1996. By 1999, the United States Navy had transferred military support operations for Antarctica over to the United States Air Force and its contractor Raytheon Polar Services . Operation Deep Freeze was managed by the U.S. Air Force and Air National Guard members of Air National Guard Detachment 13 , a subordinate unit which administratively reported directly to

576-478: Is due to contact with the Earth's surface while radiative losses to space are mostly constant. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. Earth's weather system is a chaotic system ; as a result, small changes to one part of the system can grow to have large effects on the system as a whole. Human attempts to control

648-643: Is the saving of Japan from invasion by the Mongol fleet of Kublai Khan by the Kamikaze winds in 1281. French claims to Florida came to an end in 1565 when a hurricane destroyed the French fleet, allowing Spain to conquer Fort Caroline . More recently, Hurricane Katrina redistributed over one million people from the central Gulf coast elsewhere across the United States, becoming the largest diaspora in

720-587: Is the study of short-lived atmospheric phenomena smaller than mesoscale , about 1 km or less. These two branches of meteorology are sometimes grouped together as "mesoscale and microscale meteorology" (MMM) and together study all phenomena smaller than synoptic scale ; that is they study features generally too small to be depicted on a weather map . These include small and generally fleeting cloud "puffs" and other small cloud features. On Earth, temperatures usually range ±40 °C (100 °F to −40 °F) annually. The range of climates and latitudes across

792-526: Is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth. Weather is driven by air pressure , temperature , and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude . The strong temperature contrast between polar and tropical air gives rise to

864-470: Is thought to have easterly winds moving at more than 9,600 kilometres per hour (6,000 mph). Weather is not limited to planetary bodies. Like all stars, the Sun's corona is constantly being lost to space, creating what is essentially a very thin atmosphere throughout the Solar System . The movement of mass ejected from the Sun is known as the solar wind . Inconsistencies in this wind and larger events on

936-678: The Air Staff , and the United States Navy. Among other issues, it was difficult at first for the Air Guard to convince the Air Staff to commit long term resources to an area of the world that had not been declared a warfighting region because of international treaties. The Air Guard had supported military operations in Greenland and the Arctic (including classified U.S. Navy operations) since

1008-618: The Anderson Hills . In the southwest, Snake Ridge is at the center of a scattered group of nunataks . Mackin Table is in the southeast. Geographical features that contain or are the focus of groups of lesser features include: Operation Deep Freeze Operation Deep Freeze is codename for a series of United States missions to Antarctica , beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on. (There

1080-467: The Hadley cell while a smaller scale example would be coastal breezes . The atmosphere is a chaotic system . As a result, small changes to one part of the system can accumulate and magnify to cause large effects on the system as a whole. This atmospheric instability makes weather forecasting less predictable than tidal waves or eclipses. Although it is difficult to accurately predict weather more than

1152-598: The Ross Sea . Byrd was instrumental in the Navy's Operation Highjump after World War II from 1946 to 1947, which charted most of the Antarctic coastline. In 1948, Commander Finn Ronne led an expedition that photographed over 450,000 square miles (1.1 million km ) by air. Then in 1954–55, the icebreaker USS Atka made a scouting expedition for future landing sites and bays. The impetus behind Operation Deep Freeze I

1224-727: The United States National Guard announced that the 109th Airlift Wing at Schenectady County Airport in Scotia, New York was slated to assume that entire mission from the United States Navy in 1999. The Antarctic operation would be fully funded by the National Science Foundation. The 109th expected to add approximately 235 full-time personnel to support that operation. The decision to switch from Naval leadership to National Guard

1296-696: The Virgin Islands . As of 2019, tornadoes have had the greatest impact on humans with 42 fatalities while costing crop and property damage over 3 billion dollars. The weather has played a large and sometimes direct part in human history . Aside from climatic changes that have caused the gradual drift of populations (for example the desertification of the Middle East, and the formation of land bridges during glacial periods), extreme weather events have caused smaller scale population movements and intruded directly in historical events. One such event

1368-648: The adiabatic lapse rate . In some situations, the temperature actually increases with height. This phenomenon is known as an inversion and can cause mountaintops to be warmer than the valleys below. Inversions can lead to the formation of fog and often act as a cap that suppresses thunderstorm development. On local scales, temperature differences can occur because different surfaces (such as oceans, forests, ice sheets, or human-made objects) have differing physical characteristics such as reflectivity , roughness, or moisture content. Surface temperature differences in turn cause pressure differences. A hot surface warms

1440-767: The jet stream flow (see baroclinity ). Weather systems in the tropics, such as monsoons or organized thunderstorm systems, are caused by different processes. Because the Earth's axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. In June the Northern Hemisphere is tilted towards the Sun , so at any given Northern Hemisphere latitude sunlight falls more directly on that spot than in December (see Effect of sun angle on climate ). This effect causes seasons. Over thousands to hundreds of thousands of years, changes in Earth's orbital parameters affect

1512-448: The 109th would be largely out of business because its primary mission had ended. The unit had been informally keeping tabs on Navy LC-130 operations supporting the National Science Foundation in Antarctica. Because of its aging aircraft fleet and extensive depot maintenance period, the United States Navy asked if the 109th could provide limited emergency search and rescue (SAR) capability for two years to support Operation Deep Freeze, which

SECTION 20

1584-507: The Air Guard accepted. At that time, it had no thought of taking over the mission. The 109th believed it to be an exercise in futility for its aircraft to deploy to the Antarctic to merely wait for emergency SAR missions, so it asked if the Navy could help carry cargo to the South Pole . The Navy resisted at first because its procedures and cargo configurations differed from those of the Air Guard, but eventually it agreed. The main mission of

1656-803: The Air National Guard Readiness Center (ANGRC) at Andrews Air Force Base in Maryland , and operationally reported to United States Pacific Command (USPACOM) in Honolulu, Hawaii . Upon its deactivation in 2005, the detachment consisted of a full-time officer (Commander) and four full-time non-commissioned officers (Logistics, Communications, Security Forces, and Information Management) which remained in New Zealand year-round. Operational command now belongs to Commander, Thirteenth Air Force as part of USPACOM. In 2005, through

1728-519: The Antarctic continent are overseen by the United States Antarctic Program as well as the National Science Foundation. Military support missions flown from Christchurch International Airport are conducted during the Antarctic summer (late September to early March) each year by The 109th Airlift Wing Scotia New York. The Ski equipped LC-130 Hercules is the backbone of Operation Deep Freeze. LC-130 Hercules aircraft provide

1800-440: The Earth. The process of weathering breaks down the rocks and soils into smaller fragments and then into their constituent substances. During rains precipitation, the water droplets absorb and dissolve carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic, which aids the erosive properties of water. The released sediment and chemicals are then free to take part in chemical reactions that can affect

1872-585: The Middle Ages. Finland suffered a severe famine in 1696–1697, during which about one-third of the Finnish population died. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. Human beings have attempted to predict the weather informally for millennia, and formally since at least the nineteenth century. Weather forecasts are made by collecting quantitative data about

1944-788: The South Pole. The aircraft was named Que Sera, Sera after a popular song and is now on display at the Naval Aviation Museum in Pensacola, Florida . This marked the beginning of the establishment of the first permanent base, by airlift, at the South Pole (today known as the Amundsen–Scott South Pole Station ) to support the International Geophysical Year. It was commissioned on January 1, 1957. The original station ("Old Byrd") lasted about four years before it began to collapse under

2016-468: The U.S. Navy and Air National Guard C-130s was to airlift fuel and supplies to the National Science Foundation's South Pole Station so that its personnel could survive the isolation of the long Antarctic winter, which lasted from February to October. An Air National Guard working group had been formed to study the idea in 1990. The following year, a dialog began among the Air National Guard,

2088-534: The air above it causing it to expand and lower the density and the resulting surface air pressure . The resulting horizontal pressure gradient moves the air from higher to lower pressure regions, creating a wind, and the Earth's rotation then causes deflection of this airflow due to the Coriolis effect . The simple systems thus formed can then display emergent behaviour to produce more complex systems and thus other weather phenomena. Large scale examples include

2160-527: The amount and distribution of solar energy received by the Earth and influence long-term climate. (See Milankovitch cycles ). The uneven solar heating (the formation of zones of temperature and moisture gradients, or frontogenesis ) can also be due to the weather itself in the form of cloudiness and precipitation. Higher altitudes are typically cooler than lower altitudes, which is the result of higher surface temperature and radiational heating, which produces

2232-432: The current state of the atmosphere and using scientific understanding of atmospheric processes to project how the atmosphere will evolve. Once an all-human endeavor based mainly upon changes in barometric pressure , current weather conditions, and sky condition, forecast models are now used to determine future conditions. On the other hand, human input is still required to pick the best possible forecast model to base

2304-686: The difference in current time and the time for which the forecast is being made (the range of the forecast) increases. The use of ensembles and model consensus helps to narrow the error and pick the most likely outcome. There are a variety of end users to weather forecasts. Weather warnings are important forecasts because they are used to protect life and property. Forecasts based on temperature and precipitation are important to agriculture, and therefore to commodity traders within stock markets. Temperature forecasts are used by utility companies to estimate demand over coming days. In some areas, people use weather forecasts to determine what to wear on

2376-405: The effect it has on humans in different situations, etc. Therefore, weather is something people often communicate about. The National Weather Service has an annual report for fatalities, injury, and total damage costs which include crop and property. They gather this data via National Weather Service offices located throughout the 50 states in the United States as well as Puerto Rico , Guam , and

2448-560: The expedition. Task Force 43 consisted of the following ships: The ships of the task force were supplemented by a specially trained Navy Construction Battalion , formed at the Naval Construction Battalion Center at Davisville, Rhode Island and several aircraft. On October 31, 1956, at 8:34 p.m. local time, the first aircraft ever to touch down at the South Pole skied to a halt atop the Antarctic ice sheet at 90 degrees South latitude. The U.S. Navy R4D,

2520-519: The first to stand there since Briton Robert Falcon Scott did more than 40 years before. Norwegian Roald Amundsen had beaten Scott in his race to the Pole. Amundsen's party survived the 800-mile return trip, Scott's did not. This flight was one part of the expeditions mounted for the IGY. This was not only the first aircraft to land at the South Pole, it was also the first time that Americans had ever set foot on

2592-464: The forecast upon, which involves many disciplines such as pattern recognition skills, teleconnections , knowledge of model performance, and knowledge of model biases. The chaotic nature of the atmosphere, the massive computational power required to solve the equations that describe the atmosphere, the error involved in measuring the initial conditions, and an incomplete understanding of atmospheric processes mean that forecasts become less accurate as of

2664-858: The greatest snowfall in a period of twelve months occurred in Mount Rainier , Washington, US. It was recorded as 31,102 mm (102.04 ft) of snow. Studying how the weather works on other planets has been seen as helpful in understanding how it works on Earth. Weather on other planets follows many of the same physical principles as weather on Earth , but occurs on different scales and in atmospheres having different chemical composition. The Cassini–Huygens mission to Titan discovered clouds formed from methane or ethane which deposit rain composed of liquid methane and other organic compounds . Earth's atmosphere includes six latitudinal circulation zones, three in each hemisphere. In contrast, Jupiter's banded appearance shows many such zones, Titan has

2736-675: The history of the United States. The Little Ice Age caused crop failures and famines in Europe. During the period known as the Grindelwald Fluctuation (1560–1630), volcanic forcing events seem to have led to more extreme weather events. These included droughts, storms and unseasonal blizzards, as well as causing the Swiss Grindelwald Glacier to expand. The 1690s saw the worst famine in France since

2808-461: The largest scale atmospheric circulations : the Hadley cell , the Ferrel cell , the polar cell , and the jet stream . Weather systems in the middle latitudes , such as extratropical cyclones , are caused by instabilities of the jet streamflow. Because Earth's axis is tilted relative to its orbital plane (called the ecliptic ), sunlight is incident at different angles at different times of

2880-709: The logistical movement of cargo to remote operating locations on the continent. These aircraft are augmented by the United States Coast Guard icebreaker USCGC Polar Star , the Air Force Materiel Command , and the Military Sealift Command . The United States Air Force 13th Air Expeditionary Group deploys to Christchurch, New Zealand during the operational season. A documentary on the early missions, Ice Eagles: An Account of American Aviation in Antarctica ,

2952-464: The mid-1970s with the ski-equipped C-130s of the 109th Airlift Wing . It convinced Headquarters, United States Air Force that it was not in the nation's best interest to abandon the capability to achieve quick and reliable air access to both polar regions. In March 1993, the U.S. Navy hosted a two-day workshop with representatives of the National Science Foundation, Air National Guard, and other interested parties to explore logistics support options for

3024-452: The mission. The Navy's Antarctic Development Squadron Six had been flying scientific and military missions to Greenland and the arctic compound's Williams Field since 1975. The 109th operated ski-equipped LC-130s had been flying National Science Foundation support missions to Antarctica since 1988. The official name for the Navy's command in Antarctica was US Naval Support Force Antarctica, (NSFA) Terminal Operations. In early 1996,

3096-461: The mission. When fully transitioned to the Air National Guard, the 109th Airlift Wing would have ten LC-130s in its inventory. These would include upgrades of four LC-130 aircraft in-service with the unit plus three new aircraft and three that would be transferred from the U.S. Navy. Air National Guard estimates of the savings to be realized by consolidating the operation in the hands of the 109th Airlift Wing ranged from US $ 5 million to US$ 15 million

3168-772: The mouth of the Patuxent River . The range was mapped in detail by USGS from surveys and U.S. Navy air photos, 1956-66. Download coordinates as: The Putuxent Range lies to the south of the Foundation Ice Stream, west of the Academy Glacier and northeast of the Patuxent Ice Stream. In the north, the Thomas Hills run along the south side of the Foundation Ice Stream. The MacNamara Glacier to their south separates them from

3240-697: The office of the Secretary of Defense, the commander of U.S. Pacific Command was designated to support the Joint Task Force Support Forces Antarctica, Operation Deep Freeze. CDRUSPACOM delegated this joint operation to the Commander, Pacific Air Forces , who then delegated primary responsibility for execution of the JTF SFA operation to the Commander, 13th Air Force . United States civilian and scientific operations on

3312-656: The operation. A draft concept of operations had been prepared by the Air Directorate of the National Guard Bureau in 1993. In February 1996, a commitment was made to transfer the Operation Deep Freeze mission and all LC-130H aircraft operating within the U.S. Department of Defense to the Air National Guard. In September 1996, senior officers from the 109th Airlift Wing briefed the National Guard Bureau on their concept of operations and

3384-417: The planet Neptune . This has created a puzzle for planetary scientists . The weather is ultimately created by solar energy and the amount of energy received by Neptune is only about 1 ⁄ 900 of that received by Earth, yet the intensity of weather phenomena on Neptune is far greater than on Earth. As of 2007 , the strongest planetary winds discovered are on the extrasolar planet HD 189733 b , which

3456-502: The planet can offer extremes of temperature outside this range. The coldest air temperature ever recorded on Earth is −89.2 °C (−128.6 °F), at Vostok Station , Antarctica on 21 July 1983. The hottest air temperature ever recorded was 57.7 °C (135.9 °F) at 'Aziziya , Libya, on 13 September 1922, but that reading is queried . The highest recorded average annual temperature was 34.4 °C (93.9 °F) at Dallol , Ethiopia. The coldest recorded average annual temperature

3528-629: The snow. Construction of a second underground station in a nearby location began in 1960, and it was used until 1972. The station was then converted into a summer-only field camp until it was abandoned in 2004–05. The mission's second base, Byrd Station , was a (former) research station in West Antarctica established by the US Navy for Operation Deep Freeze II during the International Geophysical Year. The United States Antarctic Program airfield, built to service Operation Deep Freeze (first mission)

3600-537: The southwest and Beijing's Fangshan District recording a rainfall of 25 millimeters. Whereas there is inconclusive evidence for these techniques' efficacy, there is extensive evidence that human activity such as agriculture and industry results in inadvertent weather modification: The effects of inadvertent weather modification may pose serious threats to many aspects of civilization, including ecosystems , natural resources , food and fiber production, economic development , and human health. Microscale meteorology

3672-465: The status of their preparations to implement Operation Deep Freeze. Under the transition plan which they had developed, the Air National Guard would continue to augment the United States Navy during the October 1996 – March 1997 operating season for the United States Antarctic Program . At the end of the October 1997 – March 1998 season, the Air National Guard would assume command of the program. During

3744-536: The surface further (such as acid rain ), and sodium and chloride ions ( salt ) deposited in the seas/oceans. The sediment may reform in time and by geological forces into other rocks and soils. In this way, weather plays a major role in erosion of the surface. Weather, seen from an anthropological perspective, is something all humans in the world constantly experience through their senses, at least while being outside. There are socially and scientifically constructed understandings of what weather is, what makes it change,

3816-400: The surface of the star, such as coronal mass ejections , form a system that has features analogous to conventional weather systems (such as pressure and wind) and is generally known as space weather . Coronal mass ejections have been tracked as far out in the Solar System as Saturn . The activity of this system can affect planetary atmospheres and occasionally surfaces. The interaction of

3888-615: The third year of the transition program (October 1998 to March 1999), the U.S. Navy would augment the ANG before the latter took over the entire program the following year. There would be seven LC-130s in theater. They would stage from Christchurch International Airport in Christchurch , New Zealand, to McMurdo Station , Antarctica. Traditional Guardsmen, technicians, and the cadre of Active Guard Reservists specifically brought on board to support Operation Deep Freeze would all be involved in

3960-411: The tropics can occur more spontaneously compared to those at higher latitudes, where they are more tightly controlled by larger-scale forces in the atmosphere. Because of these differences, clouds and rain are more difficult to forecast in the tropics than at higher latitudes. On the other hand, the temperature is easily forecast in the tropics, because it does not change much. The aspiration to control

4032-419: The tropics warm (Stevens 2011). And, the vertical direction (up, as one stands on the Earth's surface) is perpendicular to the Earth's axis of rotation at the equator, while the axis of rotation and the vertical are the same at the pole; this causes the Earth's rotation to influence the atmospheric circulation more strongly at high latitudes than low latitudes. Because of these two factors, clouds and rainstorms in

4104-453: The tropics. In other words, the farther from the tropics one lies, the lower the sun angle is, which causes those locations to be cooler due to the spread of the sunlight over a greater surface. The strong temperature contrast between polar and tropical air gives rise to the large scale atmospheric circulation cells and the jet stream . Weather systems in the mid-latitudes, such as extratropical cyclones , are caused by instabilities of

4176-411: The troposphere (the lower part of the atmosphere). Weather does occur in the stratosphere and can affect weather lower down in the troposphere, but the exact mechanisms are poorly understood. Weather occurs primarily due to air pressure, temperature and moisture differences from one place to another. These differences can occur due to the sun angle at any particular spot, which varies by latitude in

4248-420: The weather have occurred throughout history, and there is evidence that human activities such as agriculture and industry have modified weather patterns. Studying how the weather works on other planets has been helpful in understanding how weather works on Earth. A famous landmark in the Solar System , Jupiter's Great Red Spot , is an anticyclonic storm known to have existed for at least 300 years. However,

4320-603: The weather is evident throughout human history: from ancient rituals intended to bring rain for crops to the U.S. Military Operation Popeye , an attempt to disrupt supply lines by lengthening the North Vietnamese monsoon . The most successful attempts at influencing weather involve cloud seeding ; they include the fog - and low stratus dispersion techniques employed by major airports, techniques used to increase winter precipitation over mountains, and techniques to suppress hail . A recent example of weather control

4392-575: The weather is not limited to planetary bodies. A star's corona is constantly being lost to space, creating what is essentially a very thin atmosphere throughout the Solar System. The movement of mass ejected from the Sun is known as the solar wind . On Earth , common weather phenomena include wind, cloud , rain, snow, fog and dust storms . Less common events include natural disasters such as tornadoes , hurricanes , typhoons and ice storms . Almost all familiar weather phenomena occur in

4464-447: The year. On Earth's surface, temperatures usually range ±40 °C (−40 °F to 104 °F) annually. Over thousands of years, changes in Earth's orbit can affect the amount and distribution of solar energy received by Earth, thus influencing long-term climate and global climate change . Surface temperature differences in turn cause pressure differences. Higher altitudes are cooler than lower altitudes, as most atmospheric heating

4536-561: Was China's preparation for the 2008 Summer Olympic Games . China shot 1,104 rain dispersal rockets from 21 sites in the city of Beijing in an effort to keep rain away from the opening ceremony of the games on 8 August 2008. Guo Hu, head of the Beijing Municipal Meteorological Bureau (BMB), confirmed the success of the operation with 100 millimeters falling in Baoding City of Hebei Province , to

4608-496: Was an initial operation before Admiral Richard Byrd proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the United States military . Task Force 199 was involved. The U.S. Navy already had

4680-442: Was formed to provide logistical support for the expedition. Operation Deep Freeze I prepared a permanent research station and paved the way for more exhaustive research in later Deep Freeze operations. The expedition transpired over the Antarctic summer of November 1955 to April 1956, and was filmed by the U.S. Navy and Walt Disney Studios . For having designed the emblem of Task Force 43, Walt Disney became an honorary member of

4752-601: Was later named Williams Field or Willy Field. The Operation Deep Freeze activities were succeeded by "Operation Deep Freeze II", and so on. In 1960, the year of the fifth mission, codenames began to be based on the year (e.g., "Operation Deep Freeze 60"). The Coast Guard sometimes participated; among others, the USCGC Northwind , the USCGC Polar Sea and the USCGC Glacier occasionally supported

4824-608: Was one of a cost-saving measure due to post cold war budget cuts. The possibility of the Air National Guard assuming operational control of the mission had first emerged in 1988. The 109th Airlift Wing had been notified that, almost overnight, one of the Distant Early Warning Line (DEW) radar sites that it supported in Greenland was going to be shut down. The other sites would soon follow, and

4896-411: Was piloted by Lieutenant Commander (LCDR) Conrad C. "Gus" Shinn USN and included officer Frederick Ferrara. Immediately after the plane halted--with engines running to avoid a freeze-up (a practice still followed to this day)--U.S. Navy Adm. George J. Dufek., commander of Operation Deep Freeze, stepped out onto the ice, along with pilot Douglas Cordiner, to plant the stars and stripes at the Pole. They were

4968-416: Was scheduled to be released in 2016. Lockheed Martin is currently the prime contractor for the National Science Foundation's United States Antarctic Program. The contract award was announced via a NSF press release on 28 December 2011 after a bid solicitation process of almost four years. Support operations began on 1 April 2012. The original contract synopsis indicated that the government was contemplating

5040-639: Was the International Geophysical Year 1957–58. IGY as it was known was a collaborative effort among forty nations to carry out earth science studies from the North Pole to the South Pole and at points in between. The United States along with New Zealand , the United Kingdom , France , Japan , Norway , Chile , Argentina , and the U.S.S.R. agreed to go to the South Pole, the least explored area on Earth. Their goal

5112-432: Was to advance world knowledge of Antarctic hydrography and weather systems , glacial movements , and marine life . The U.S. Navy was charged with supporting the U.S. scientists for their portion of the IGY studies. Rear Admiral Richard E. Byrd , a veteran of four previous Antarctic Expeditions, was appointed as officer in charge of the expedition. In 1955, Task Force 43, commanded by Rear Admiral George J. Dufek ,

5184-461: Was −55.1 °C (−67.2 °F) at Vostok Station , Antarctica. The coldest average annual temperature in a permanently inhabited location is at Eureka, Nunavut , in Canada, where the annual average temperature is −19.7 °C (−3.5 °F). The windiest place ever recorded is in Antarctica, Commonwealth Bay (George V Coast). Here the gales reach 199 mph (320  km/h ). Furthermore,
