...Bolshoi Teleskop Azimutalnyi. This is the famous Soviet (now Russian) 6-meter telescope, in operation since 1976. The first really large optical telescope to incorporate an altazimuth mount (and thus requiring constant computer control to operate), it is located on the slopes of Mount Pastukhov on the northern side of the Caucasus range, between the Black and Caspian Seas. The telescope uses an f/4 primary mirror (giving a 26-meter tube housed in a dome 58 meters high), with instruments located in an expansive prime-focus housing or at one of the Nasmyth foci on either side of the fork mount (one of the spectrographs has a collimator 2 meters across). ...

...Radiocarbon Dating Virtual Course... The radiocarbon dating method was developed in the 1940's by Willard F. Libby and a team of scientists at the University of Chicago. It subsequently evolved into the most powerful method of dating late Pleistocene and Holocene artifacts and geologic events up to about 50,000 years in age. The radiocarbon method is applied in many different scientific fields, including archeology, geology, oceanography, hydrology, atmospheric science, and paleoclimatology. For his leadership, Libby received the Nobel Prize in Chemistry in 1960. ...

United StatesSubmarine Mountains   http://www.ucmp.berkeley.edu/fosrec/Metzger2.html  [ Edit ]  Site Reviews(0)
...The first use of sonar (Sound Navigational Ranging) to locate underwater features was aboard the German research ship Meteor. Sonar devices use echoes from the ocean floor (or other underwater sound emitters such as a ship's hull) to measure ocean depth.The Meteor made 13 Atlantic crossings between 1925 and 1927, mapping the ocean bottom continuously. Sonar systems became highly accurate during World War II, when submarine warfare raged in both the Atlantic and Pacific oceans. Deep-ocean trenches in the western Pacific provided havens for Japanese submarines because they were too deep for sonar to penetrate. The use of sonar to map the sea floor following World War II dispelled any lingering notions that the Earth's ocean floors were featureless plains. Scientists mapped oceanic ridges, submerged islands, plateaus, and trenches — discoveries which helped with the understanding of plate tectonics. In the late 1960's the National Geographic Society published maps showing the topography of the ocean floors, allowing the general public to see the underwater part of the planet for the first time. ...
