Walgreen Coast
The Walgreen Coast () is a portion of the coast of Antarctica between Cape Herlacher and Cape Waite, or between Eights Coast on the east and Bakutis Coast in the west. It is part of Marie Byrd Land. It extends from 103°24'W to 114°12'W. It was discovered by Richard E. Byrd and members of the US Antarctic Service (USAS) by flights from the USS Bear, USS ''Bear'' during February 1940. The Walgreen Coast was named by Byrd after Charles R. Walgreen, president of the retail company Walgreens at the time, who was a funder of the Byrd Antarctic Expedition, 1933–1935, and assisted in equipping the ''Bear'' for the USAS, 1939–1941. This coast was mapped in detail by the United States Geological Survey from ground surveys and U.S. Navy air photographs, 1959–66. It contains Thwaites Glacier, also known as the "Doomsday Glacier", for its major contributions to sea level rise as a result of climate change.

Charles R
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depr ...

Wright Pass
Wright Pass () is a snow pass to the west of Jones Bluffs, running north–south for 3 nautical miles (6 km) between the terminus of Holt Glacier and the vicinity of Mayo Peak, Bear Peninsula on the Walgreen Coast, Marie Byrd Land. Mapped by United States Geological Survey (USGS) from U.S. Navy aerial photographs taken 1966. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1977 after Chief Petty Officer William L. Wright, U.S. Navy, who completed six Operation Deepfreeze deployments up to 1977. As Leading Petty Officer (Transportation Operations), he conducted cargo traverses across the ice of McMurdo Sound to the McMurdo Dry Valleys The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby .... References Mountain passes of Antarctica Landforms of Marie Byrd L ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Sea Level Rise
Globally, sea levels are rising due to human-caused climate change. Between 1901 and 2018, the globally averaged sea level rose by , or 1–2 mm per year on average.IPCC, 2019Summary for Policymakers InIPCC Special Report on the Ocean and Cryosphere in a Changing Climate .-O. Pörtner, D.C. Roberts, V. Masson-Delmotte, P. Zhai, M. Tignor, E. Poloczanska, K. Mintenbeck, A. Alegría, M. Nicolai, A. Okem, J. Petzold, B. Rama, N.M. Weyer (eds.) Cambridge University Press, Cambridge, UK and New York, NY, USA. https://doi.org/10.1017/9781009157964.001. This rate is accelerating, with sea levels now rising by 3.7 mm per year. Climate scientists expect further acceleration during the 21st century. Climate change heats (and therefore expands) the ocean and melts land-based ice sheets and glaciers. Between 1993 and 2018, the thermal expansion of water contributed 42% to sea level rise; melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Over the next 2 ...

Thwaites Glacier
Thwaites Glacier, nicknamed the Doomsday Glacier, is an unusually broad and vast Antarctic glacier flowing into Pine Island Bay, part of the Amundsen Sea, east of Mount Murphy, on the Walgreen Coast of Marie Byrd Land. Its surface speeds exceed per year near its grounding line. Its fastest-flowing grounded ice is centered between east of Mount Murphy. In 1967, the Advisory Committee on Antarctic Names named the glacier after Fredrik T. Thwaites (1883–1961), a glacial geologist, geomorphologist and professor emeritus at the University of Wisconsin–Madison. Thwaites Glacier is closely monitored for its potential to raise sea levels. Along with the Pine Island Glacier, it has been described as part of the "weak underbelly" of the West Antarctic Ice Sheet, because of its apparent vulnerability to significant retreat. This hypothesis is based on both theoretical studies of the stability of marine ice sheets and observations of large changes on these two glaciers. In recent ...

Byrd Antarctic Expedition
Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an American naval officer and explorer. He was a recipient of the Medal of Honor, the highest honor for valor given by the United States, and was a pioneering American 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. Byrd said that his expeditions had been the first to reach both the North Pole and the South Pole by air. His belief to have reached the North Pole is disputed. He is also known for discovering Mount Sidley, the largest dormant volcano in Antarctica. Family Ancestry Byrd was born in Winchester, Virginia, the son of Esther Bolling (Flood) and Richard Evelyn Byrd Sr. He was a descendant of one of the First Families of Virginia. His ancestors include planter John Rolfe and his wife Pocahontas, William Byrd II of Westover Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

USS Bear
USS ''Bear'' was a dual steam-powered and sailing ship built with -thick sides which had a long life in various cold-water and ice-filled environs. She was a forerunner of modern icebreakers and had a diverse service life. According to the United States Coast Guard official website, ''Bear'' is described as "probably the most famous ship in the history of the Coast Guard." Built in Scotland in 1874 as a steamer for sealing, she was owned and operated from Newfoundland for ten years. In the mid-1880s, she took part in the search for the Greely Expedition. Captained by Michael Healy of the United States Revenue Cutter Service (later part of the U.S. Coast Guard), she worked the coastline of Alaska. She later assisted with relief efforts after the 1906 San Francisco earthquake. Her services also included the second expedition of Admiral Richard E. Byrd to Antarctica, and again to the southernmost continent in 1941 to evacuate Americans at the beginning of World War II. She lat ...
