Berkner Island
Berkner Island (also known as the Berkner Ice Rise or as Hubley Island) is an Antarctic ice rise, where bedrock below sea level has caused the surrounding ice sheet to create a dome. If the ice cap were removed, the island would be underwater. Berkner Island is completely ice-covered and is about long and wide, with an area of . It is surrounded by the Filchner-Ronne Ice Shelf. The northernmost point of the Berkner is about from the open sea. It lies in the overlapping portion of the Argentine and the British Antarctic territorial claims. The island rises to (, according to other sources) and separates the Ronne Ice Shelf from the Filchner Ice Shelf. It is characterized by two domes, ''Reinwarthhöhe'' in the north (), and ''Thyssenhöhe'' in the south ().

Hemmen Ice Rise
Hemmen Ice Rise () is an ice rise long and wide, with an estimated area of , located off the northwest corner of Berkner Island in the Ronne Ice Shelf, Antarctica. The feature appears for the first time on a chart prepared at Ellsworth Station in 1957 by Captain Finn Ronne, U.S. Navy Reserve. The ice rise was subsequently noted in U.S. Earth Resources Technology Satellite imagery. It was named by the UK Antarctic Place-Names Committee for George E. Hemmen, Executive Secretary of the Scientific Committee on Antarctic Research in 1972; he served with the Falkland Islands Dependencies Survey as a meteorological observer at Admiralty Bay, 1952–53, and as Base Leader at Deception Island Deception Island is in the South Shetland Islands close to the Antarctic Peninsula with a large and usually "safe" natural harbour, which is occasionally affected by the underlying active volcano.

Ice Core
An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires .... Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper ones, and an ice core contains ice formed over a range of years. Cores are Ice drilling, drilled with hand Auger (drill), augers (for shallow holes) or powered drills; they can reach depths of over two miles (3.2 km), and contain ice up to 800,000 years old. The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core. The proportions of different oxygen and hydrogen isotopes provide information about Paleothermometer, ancient temperatures, a ...

Byrd Antarctic Expedition
Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an United States Navy, American naval officer, and pioneering aviator, polar explorer, and organizer of polar logistics. Aircraft flights in which he served as a navigator and expedition leader crossed the Atlantic Ocean, a segment of the Arctic Ocean, and a segment of the Antarctic Plateau. He is also known for discovering Mount Sidley, the largest dormant volcano in Antarctica. Byrd claimed to be the first to reach both the North Pole, North and South Poles by air. However, there is some controversy as to whether Byrd was actually the first person to reach the North Pole. It is generally believed that the distance Byrd claimed to fly was longer than the possible fuel range of his airplane. He was a List of Medal of Honor recipients during peacetime, recipient of the Medal of Honor, the United States Armed Forces' highest military decoration, and the Navy Cross, the second highest honor for valor given by the U ...

Lloyd Berkner
Lloyd Viel Berkner (February 1, 1905 – June 4, 1967) was an American physicist and engineer. He was one of the inventors of the measuring device that since has become standard at ionospheric stations because it measures the height and electron density of the ionosphere. The data obtained in the worldwide net of such instruments were important for the developing theory of short wave radio propagation to which Berkner himself gave important contributions. Berkner was elected to the United States National Academy of Sciences in 1948. He was president of Associated Universities, Inc. from 1951 to 1960. Later he investigated the development of the Earth's atmosphere. Since he needed data from the whole world, he proposed the International Geophysical Year in 1950. At that time, the IGY was the largest cooperative study of the Earth ever undertaken. Berkner was elected a Fellow of the American Academy of Arts and Sciences and a member of the American Philosophical Society in 1956 ...
