The Hollow Earth is an obsolete concept proposing that the planet Earth is entirely hollow or contains a substantial interior space. Notably suggested by Edmond Halley in the late 17th century, the notion was disproven, first tentatively by Pierre Bouguer in 1740, then definitively by Charles Hutton in his Schiehallion experiment around 1774.
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole.
The Arctic is a polar region located at the northernmost part of Earth. The Arctic region, from the IERS Reference Meridian travelling east, consists of parts of northern Norway, northernmost Sweden, northern Finland, Russia, the United States (Alaska), Canada, Danish Realm (Greenland), and northern Iceland, along with the Arctic Ocean and adjacent seas. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost under the tundra. Arctic seas contain seasonal sea ice in many places.
Robert Edwin Peary Sr. was an American explorer and officer in the United States Navy who made several expeditions to the Arctic in the late 19th and early 20th centuries. He was long credited as being the discoverer of the geographic North Pole in April 1909, having led the first expedition to have claimed this achievement, although it is now considered unlikely that he actually reached the Pole.
The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles, lying within the polar circles. These high latitudes are dominated by floating sea ice covering much of the Arctic Ocean in the north, and by the Antarctic ice sheet on the continent of Antarctica and the Southern Ocean in the south.
In geography, a pole of inaccessibility is the farthest location in a given landmass, sea, or other topographical feature, starting from a given boundary, relative to a given criterion. A geographical criterion of inaccessibility marks a location that is the most challenging to reach according to that criterion. Often it refers to the most distant point from the coastline, implying the farthest point into a landmass from the shore, or the farthest point into a body of water from the shore. In these cases, a pole of inaccessibility is the center of a maximally large circle that can be drawn within an area of interest only touching but not crossing a coastline. Where a coast is imprecisely defined, the pole will be similarly imprecise.
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner. Tropical cyclones which cross the subtropical ridge axis into the westerlies recurve due to the increased westerly flow. The winds are predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere.
Frederick Albert Cook was an American explorer, physician and ethnographer, who is most known for allegedly being the first to reach the North Pole on April 21, 1908. A competing claim was made a year later by Robert Peary, though both men's accounts have since been fiercely disputed; in December 1909, after reviewing Cook's limited records, a commission of the University of Copenhagen ruled his claim unproven. Nonetheless, in 1911, Cook published a memoir of the expedition in which he maintained the veracity of his assertions. In addition, he also claimed to have been the first person to reach the summit of Denali, the highest mountain in North America, a claim which has since been similarly discredited. Though he may not have achieved either Denali or the North Pole, his was the first and only expedition where a United States national discovered an Arctic island, Meighen Island.
A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice.
The Norge was a semi-rigid Italian-built airship that carried out the first verified trip of any kind to the North Pole, an overflight on 12 May 1926. It was also the first aircraft to fly over the polar ice cap between Europe and America. The expedition was the brainchild of polar explorer and expedition leader Roald Amundsen, the airship's designer and pilot Umberto Nobile and the wealthy American adventurer and explorer Lincoln Ellsworth who, along with the Norwegian Aviation Society, financed the trip, which was known as the Amundsen-Ellsworth 1926 Transpolar Flight.
A Fata Morgana is a complex form of superior mirage visible in a narrow band right above the horizon. The term Fata Morgana is the Italian translation of "Morgan the Fairy". These mirages are often seen in the Italian Strait of Messina, and were described as fairy castles in the air or false land conjured by her magic.
Peary Land is a peninsula in northern Greenland, extending into the Arctic Ocean. It reaches from Victoria Fjord in the west to Independence Fjord in the south and southeast, and to the Arctic Ocean in the north, with Cape Morris Jesup, the northernmost point of Greenland's mainland, and Cape Bridgman in the northeast.
Sir Walter William Herbert was a British polar explorer, writer and artist. In 1969 he became the first man fully recognized for walking to the North Pole, on the 60th anniversary of Robert Peary's disputed expedition. He was described by Sir Ranulph Fiennes as "the greatest polar explorer of our time".
Cape Columbia is the northernmost point of land of Canada, located on Ellesmere Island in the Qikiqtaaluk Region of Nunavut. It marks the westernmost coastal point of Lincoln Sea in the Arctic Ocean. It is the world's northernmost point of land outside Greenland. The distance to the North Pole is 769 km (478 mi).
Arktika 2007 was a 2007 expedition in which Russia performed the first ever crewed descent to the ocean bottom at the North Pole, as part of research related to the 2001 Russian territorial claim, one of many territorial claims in the Arctic, made possible, in part, because of Arctic shrinkage. As well as dropping a titanium tube containing the Russian flag, the submersibles collected specimens of Arctic flora and fauna and apparently recorded video of the dives. The "North Pole-35" manned drifting ice station was established.
The first ever expedition to reach the Geographic South Pole was led by the Norwegian explorer Roald Amundsen. He and four other crew members made it to the geographical south pole on 14 December 1911, which would prove to be five weeks ahead of the competitive British party led by Robert Falcon Scott as part of the Terra Nova Expedition. Amundsen and his team returned safely to their base, and about a year later heard that Scott and his four companions had perished on their return journey.
The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. It spans an area of approximately 14,060,000 km2 (5,430,000 sq mi) and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has also been described as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing world ocean.
Arctic exploration is the physical exploration of the Arctic region of the Earth. It refers to the historical period during which mankind has explored the region north of the Arctic Circle. Historical records suggest that humankind have explored the northern extremes since 325 BC, when the ancient Greek sailor Pytheas reached a frozen sea while attempting to find a source of the metal tin. Dangerous oceans and poor weather conditions often fetter explorers attempting to reach polar regions, and journeying through these perils by sight, boat, and foot has proven difficult.
Polar exploration is the process of exploration of the polar regions of Earth – the Arctic region and Antarctica – particularly with the goal of reaching the North Pole and South Pole, respectively. Historically, this was accomplished by explorers making often arduous travels on foot or by sled in these regions, known as a polar expedition. More recently, exploration has been accomplished with technology, particularly with satellite imagery.
