Wrigley Gulf
Wrigley Gulf is an embayment about 115 miles wide along the coastline of Antarctica, lying seaward of the Getz Ice Shelf. Nearly a right angle in plan, its limits are described by Grant Island, Dean Island, and Siple Island, which are partially or wholly embedded in the ice shelf. Wrigley Gulf was discovered in December 1940 by the US Antarctic Service (USAS), and named for Philip Wrigley, a Chicago manufacturer who helped support the expedition. Further reading * Andrew J.

Embayment
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129. Bays were sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Getz Ice Shelf
The Getz Ice Shelf is the largest Antarctic ice shelf along the SE Pacific-Antarctic coastline, over long and from wide, bordering the Hobbs and Bakutis Coasts of Marie Byrd Land between the McDonald Heights and Martin Peninsula. Several large islands are partially or wholly embedded in the ice shelf, pinning the calving front. Summer temperature and salinity measurements from 1994 to 2010 show the shelf is subject to more changeable oceanic forcing than other Antarctic shelves. Beneath cold surface waters, the thermocline was ~200 m shallower in 2007 than in 2000, indicative of shifting access of deep water to the continental shelf and ice shelf base. The calculated area-average basal melt rates was between 1.1 and 4.1 m of ice per year, making Getz the largest source of meltwater to the Southern Ocean. The ice shelf westward of Siple Island was discovered by the United States Antarctic Service (USAS) in December 1940. The portion eastward of Siple Island was first delineat ...

Siple Island
Siple Island is a long snow-covered island lying east of Wrigley Gulf along the Getz Ice Shelf off Bakutis Coast of Marie Byrd Land, Antarctica. Its centre is located at . Its area is and it is dominated by the dormant shield volcano Mount Siple, rising to — making this the List of islands by highest point, 15th ranking island in the world by maximum elevation. The feature was first indicated as an island on U.S. Geological Survey (USGS) maps compiled from ground surveys and U.S. Navy air photos, 1959–65. Island and mountain were named by the United States Advisory Committee on Antarctic Names (US-ACAN) in 1967 in honour of the American Antarctic explorer Paul A. Siple (1909–1968), member of Richard E. Byrd, Admiral Byrd's expeditions.

Philip Wrigley
Philip Knight Wrigley (December 5, 1894 – April 12, 1977), often called P. K. Wrigley, was an American chewing gum manufacturer and a Major League Baseball executive, inheriting both of those roles as the quiet son of his much more flamboyant father, William Wrigley Jr. Biography Wrigley was born in Chicago in 1894. He graduated from Phillips Academy in Andover, Massachusetts, in 1914, and briefly attended the University of Chicago. His father, William Wrigley Jr., died in 1932, elevating Philip's role in the family business. He presided over the Wm. Wrigley Jr. Company, and also the family hobby, the Chicago Cubs, as owner until his death. He turned over the presidency of his chewing gum company to his son William Wrigley III in 1961, while retaining the presidency of the Cubs. While the gum industry prospered, the Cubs grew less competitive over the decades. After an appearance in the 1945 World Series, they only had seven winning seasons in the next 32 years, including 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
