Surprise Spur
Surprise Spur () is a prominent spur, the northernmost of three spurs on the southwest side of Ackerman Ridge in the La Gorce Mountains of Antarctica. First mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1960–64. So named by New Zealand Geological Survey Antarctic Expedition The New Zealand Geological Survey Antarctic Expedition (NZGSAE) describes a series of scientific explorations of the continent Antarctica. The expeditions were notably active throughout the 1950s and 1960s. Features named by the expeditions 1957 ...

Ackerman Ridge
Ackerman Ridge () is a prominent rock ridge forming the northwest extremity of the La Gorce Mountains of the Queen Maud Mountains. Discovered and roughly mapped in December 1934 by the Byrd Antarctic Expedition geological party under Quin Blackburn. Named by Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Ronnie J. Ackerman, navigator of U.S. Navy Squadron VX-6 during Operation Deep Freeze 1965 and 1966.

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] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...
