The following is a list of events that occurred in Antarctica in 2015.

Antarctica Polar continent in the Earths southern hemisphere

Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres, it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.

2015 (MMXV) was a common year starting on Thursday of the Gregorian calendar, the 2015th year of the Common Era (CE) and Anno Domini (AD) designations, the 15th year of the 3rd millennium, the 15th year of the 21st century, and the 6th year of the 2010s decade.

Events

King Baudouin Ice Shelf

The King Baudouin Ice Shelf in Dronning Maud Land, East Antarctica, is within the Norwegian part of Antarctica. It is named after King Baudouin of Belgium (1930-1993).

Queen Maud Land Norways territorial claim in Antarctica

Queen Maud Land is a c. 2.7 million square kilometre (1.04 million sq mi) region of Antarctica claimed as a dependent territory by Norway. The territory lies between 20° west and 45° east, between the claimed British Antarctic Territory to the west and the similarly claimed Australian Antarctic Territory to the east. On most maps there had been an unclaimed area between Queen Maud Land's borders of 1939 and the South Pole until 12 June 2015 when Norway formally annexed that area. Positioned in East Antarctica, the territory comprises about one-fifth of the total area of Antarctica. The claim is named after the Norwegian queen Maud of Wales (1869–1938).

The Antarctica Marathon may have been the first for-profit sporting event held in Antarctica, on January 28, 1995. The event is now held every year in late February or early March. The 42.195-kilometre (26.219 mi) race is held on King George Island, one of the largest Antarctic Islands just off the Antarctic Peninsula. There is also a half-marathon held at the same time. The start and finish is at Bellingshausen Station, and the course passes the Artigas Base (Uruguayan), the Frei Base (Chilean) and the Great Wall Base (Chinese). The course follows a gravel road that connects the bases.

Meteorite piece of solid matter from outer space that has hit the earth

A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon. When the object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate that energy. It then becomes a meteor and forms a fireball, also known as a shooting star or falling star; astronomers call the brightest examples "bolides". Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater.

Meteor Crater meteorite impact crater in the northern Arizona

Meteor Crater is a meteorite impact crater approximately 37 miles (60 km) east of Flagstaff and 18 miles (29 km) west of Winslow in the northern Arizona desert of the United States. Because the United States Board on Geographic Names commonly recognizes names of natural features derived from the nearest post office, the feature acquired the name of "Meteor Crater" from the nearby post office named Meteor. The site was formerly known as the Canyon Diablo Crater and fragments of the meteorite are officially called the Canyon Diablo Meteorite. Scientists refer to the crater as Barringer Crater in honor of Daniel Barringer, who was first to suggest that it was produced by meteorite impact. The crater is privately owned by the Barringer family through their Barringer Crater Company, which proclaims it to be the "best preserved meteorite crater on Earth". Despite its importance as a geological site, the crater is not protected as a national monument, a status that would require federal ownership. It was designated a National Natural Landmark in November 1967.

Peter I Island Norwegian territorial claim and volcanic island in the Bellingshausen Sea

Peter I Island is an uninhabited volcanic island in the Bellingshausen Sea, 450 kilometres (280 mi) from continental Antarctica. It is claimed as a dependency of Norway, and along with Bouvet Island and Queen Maud Land comprises one of the three Norwegian dependent territories in the Antarctic and Subantarctic. Peter I Island is 11 by 19 kilometres long and 156 square kilometres (60 sq mi), slightly larger than Staten Island as an example. The tallest peak is the ultra and 1,640-meter (5,380 ft) tall Lars Christensen Peak. Nearly all of the island is covered by a glacier and it is surrounded most of the year by pack ice, making it inaccessible during these times. There is little vertebrate animal life on the island apart from some seabirds and seals.

Lunar meteorite meteorite that originated from Earths Moon

A lunar meteorite is a meteorite that is known to have originated on the Moon. A meteorite hitting the Moon is normally classified as a transient lunar phenomenon.

The northernmost point is Rossøya on Svalbard, the southernmost is Pysen in Mandal, the easternmost is Kræmerpynten on Svalbard, and the westernmost is Høybergodden on Jan Mayen. The highest peak is Galdhøpiggen, standing at 2,469 m (8,100 ft) above mean sea level, while the lowest elevation is sea level at the coast.

New Swabia an area of Antarctica between 20°E and 10°W in Queen Maud Land, first explored by Nazi Germany in early 1939

New Swabia is a cartographic name sometimes given to an area of Antarctica between 20°E and 10°W in Queen Maud Land, which is claimed as a Norwegian dependent territory under the Antarctic Treaty System. New Swabia was explored by Germany in early 1939 and named after that expedition's ship, Schwabenland, itself named after the German region of Swabia.

Lars Christensen Norwegian businessman

Wilkes Land crater is an informal term that may apply to two separate cases of conjectured giant impact craters hidden beneath the ice cap of Wilkes Land, East Antarctica. These are separated below under the heading Wilkes Land anomaly and Wilkes Land mascon , based on terms used in their principal published reference sources.

Troll Airfield

Troll Airfield is an airstrip located 6.8 kilometres (4.2 mi) from the research station Troll in Princess Martha Coast in Queen Maud Land, Antarctica. Owned and operated by the Norwegian Polar Institute, it consists of a 3,300-by-100-metre runway on glacial blue ice on the Antarctic ice sheet. The airport is located at 1,232 metres (4,042 ft) above mean sea level and is 235 kilometres (146 mi) from the coast.

Tor (research station) Antarctic base in Norway

Tor research station is a Norwegian Antarctic research station in Queen Maud Land.

Dependencies of Norway

Norway has three dependent territories, all uninhabited and located in the Southern Hemisphere. Bouvetøya is a Subantarctic island in the South Atlantic Ocean. Queen Maud Land is a sector of Antarctica which spans between 20° west and 45° east. Peter I Island is a volcanic island located 450 kilometres (280 mi) off the coast of Ellsworth Land of continental Antarctica.

Sverdrup Mountains mountain range in Queen Maud Land, Antarctica

The Sverdrup Mountains are a group of mountains about 80 km (50 mi) long, standing just west of the Gjelsvik Mountains in Queen Maud Land, East Antarctica. With its summit at 2,655 metres (8,711 ft), the massive Mount Krüger forms the highest point in the Sverdrup Mountains.

The sixth Norwegian Antarctic Expedition was a scientific expedition to Queen Maud Land in Antarctica. The expedition was based at Norway Station which was located on the Fimbul Ice Shelf bordering the coast of Queen Maud Land.

Nakhlite group of Martian meteorites

Nakhlites are a group of Martian meteorites, named after the first one, Nakhla meteorite.

Hiawatha Glacier glacier in Greenland

Hiawatha Glacier is a glacier in northwest Greenland, near Inglefield Land. It was mapped in 1922 by Lauge Koch, who noted that the glacier tongue extended into Lake Alida. Hiawatha Glacier attracted attention in 2018 because of the discovery of a crater beneath the surface of the ice sheet in the area. A publication noted in 1952 that Hiawatha Glacier is retreating since 1920.
