Ross Island
Ross Island is an island formed by four volcanoes in the Ross Sea near the continent of Antarctica, off the coast of Victoria Land in McMurdo Sound. Ross Island lies within the boundaries of Ross Dependency, an area of Antarctica claimed by New Zealand. History Discovery Sir James Ross discovered it in 1840, and it was later named in honour of him by Robert F. Scott. Ross Island was the base for many of the early expeditions to Antarctica. It is the southernmost island reachable by sea. Huts built by Scott's and Shackleton's expeditions are still standing on the island, preserved as historical sites. Today Ross Island is home to New Zealand's Scott Base, and the largest Antarctic settlement, the U.S. Antarctic Program's McMurdo Station. Greenpeace established World Park Base on the island and ran it for five years, from 1987 to 1992. Geography Because of the persistent presence of the ice sheet, the island is sometimes taken to be part of the Antarctic mainland. I ...

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hill ...

Post Office Hill
Post Office Hill () is a prominent hill in Antarctica, 430 m, standing 4 nautical miles (7 km) northwest of The Knoll and overlooking the Adelie penguin rookery of Cape Crozier, Ross Island. Mapped and so named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, because the ship ''Discovery Discovery may refer to: * Discovery (observation), observing or finding something unknown * Discovery (fiction), a character's learning something unknown * Discovery (law), a process in courts of law relating to evidence Discovery, The Discover ...'', in January 1902, left messages attached to a pole in a cairn of rocks in the rookery for the relief ship ''Morning''.

Stinson Beach, California
Stinson Beach is an unincorporated community and census-designated place (CDP) in Marin County, California, on the west coast of the United States. Stinson Beach is located east-southeast of Bolinas, at an elevation of . The population of the Stinson Beach CDP was 541 at the 2020 census. Stinson Beach is about a 35-minute drive from the Golden Gate Bridge on California's Highway 1. It is near important attractions such as Muir Woods National Monument, Muir Beach, and Mount Tamalpais. It has a long beach, and the cold water produces fog throughout the year. Stinson Beach is a popular day trip for people in the San Francisco Bay Area and for tourists visiting Northern California. Although most visitors arrive by private car, Stinson Beach is linked to Marin City by a daily bus service, and the network of hiking trails around Mount Tamalpais also reaches the town. The beach is one of the cleanest in the state, and sandy, unlike the rockier neighboring beach in Bolinas. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Antarctic Program
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, and works with other federal agencies, the U.S. military, an ...

Penguin
Penguins ( order Sphenisciformes , family Spheniscidae ) are a group of aquatic flightless birds. They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow it whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend roughly half of their lives on land and the other half in the sea. The largest living species is the emperor penguin (''Aptenodytes forsteri''): on average, adults are about tall and weigh . The smallest penguin species is the little blue penguin (''Eudyptula minor''), also known as the fairy penguin, which stands around tall and weighs . Today, larger penguins generally inhabit colder regions, and smaller penguins in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skua
The skuas are a group of predatory seabirds with seven species forming the genus ''Stercorarius'', the only genus in the family Stercorariidae. The three smaller skuas, the long-tailed skua, the Arctic skua, and the pomarine skua are called jaegers in North American English. The English word "skua" comes from the Faroese name for the great skua, , with the island of Skúvoy renowned for its colony of that bird. The general Faroese term for skuas is . The word "jaeger" is derived from the German word , meaning "hunter". The genus name ''Stercorarius'' is Latin and means "of dung"; because the food disgorged by other birds when pursued by skuas was once thought to be excrement. Skuas nest on the ground in temperate and Arctic regions, and are long-distance migrants. They have even been sighted at the South Pole. Biology and habits Outside the breeding season, skuas take fish, offal, and carrion. Many practice kleptoparasitism, which comprises up to 95% of the feeding ...

Cape Crozier
Cape Crozier is the most easterly point of Ross Island in Antarctica. It was discovered in 1841 during James Clark Ross's expedition of 1839 to 1843 with HMS ''Erebus'' and HMS ''Terror'', and was named after Francis Crozier, captain of HMS ''Terror''. The extinct volcano Mount Terror, also named during the Ross expedition, rises sharply from the Cape to a height of , and the edge of the Ross Ice Shelf (formerly known as the Barrier or Great Ice Barrier) stretches away to its east. History First landing, 1902 The first landing at Cape Crozier was on 22 January 1902, during Captain Scott's ''Discovery'' Expedition. A party from RRS ''Discovery'' landed by small boat on a stony beach area a little to the west of the Cape. Scott, Edward Wilson and Charles Royds climbed the slope to a vantage point from which they could view the Barrier surface, and they were also able to observe the large Adelie penguin colony which inhabited the surrounding ice-free terrain. ;Historic s ...

McMurdo Sound
McMurdo Sound is a sound in Antarctica. It is the southernmost navigable body of water in the world, and is about from the South Pole. Captain James Clark Ross discovered the sound in February 1841, and named it after Lt. Archibald McMurdo of HMS ''Terror''. The sound today serves as a resupply route for cargo ships and for airplanes that land on the floating ice airstrips near McMurdo Station. Physical characteristics Wildlife in the sound include killer whales, seals, Adélie penguins, and emperor penguins. Boundary and Extents The sound extends approximately 55 kilometers (34 mi) in length and width, and opens into the larger Ross Sea to the north. To the south, the sound is bounded by the Ross Ice Shelf cavity, to the west lies the Royal Society Range, and to the east is Ross Island. McMurdo Sound is separated from the McMurdo Ice Shelf (itself part of the Ross Ice Shelf) by the Haskell Strait. Winter Quarters Bay lies at the south end of the Sound, and i ...
