bathythermograph การใช้

• She was equipped with a deep water mechanical bathythermograph instrument.
• During her ensuing overhaul, she received a bathythermograph and a high periscope.
• These include radar, the plan position indicator radar display, and the bathythermograph.
• The bathythermograph was invented in 1937, which was soon fitted to ASW ships.
• "1975 Colborn " : climatological analysis of the entire Indian Ocean from bathythermograph and hydrocast observations
• Various hydrographic and bathythermograph winches and booms were installed, as was sonar, dead reckoning, and various electronic equipment.
• After witnessing firsthand the dangers of deploying and retrieving BTs, James M . Snodgrass began developing the expendable bathythermograph ( XBT ).
• Throughout the use of the bathythermograph various technicians, watchstanders, and oceanographers noted how dangerous the deployment and retrieval of the BT was.
• Spilhaus'bathythermograph was a tube-shaped projectile that sank fast in seawater and contained a stylus that recorded temperature changes on interior glass.
• By mid-September she had surveyed routes from Herschel Island to Shepherd Bay, taking continuous soundings and compiling bathythermograph information and gathering core samplings every 20 miles.
• During the patrol, she would also test the effectiveness of the high periscope in daytime attacks and the usefulness of the bathythermograph in locating thermal layers in which to hide.
• Quantities of uncooked rice and beans, unlike those used on the submarine, were found between the wooden deck pieces of the cigarette deck, on the bridge, and caught in the bathythermograph.
• There he started the meteorology and oceanographic department and invented the bathythermograph, which was used in World War II to correct inaccuracies in sonar readings that were allowing German submarines to elude detection and sink U . S . destroyers.
• In 1936 Spilhaus joined the Woods Hole Oceanographic Institution in Massachusetts, where he developed the bathythermograph, which made the measurement of ocean depths and temperatures from a moving vessel possible, a device which proved indispensable to submarine warfare.
• The bathythermograph was developed by Carl-Gustav Rossby and turned into a production model for Navy use by Athelstan Spilhaus working with Maurice Ewing and sound channel, a layer of minimum velocity, allowing detection of sound at very long ranges.
• Throughout the expedition, as water depths and conditions permitted, " Pioneer " made the same routine hydrographic, magnetic, gravimetric, and bathythermograph measurements and observations, plankton tows, and biological productivity hauls that she had made during her February voyage from California to Honolulu.
• After calling at Naval Station Kodiak for supplies, she departed Kodiak on 1 September 1962, ran a magnetic survey and gravimetric transect of about 1, 400 nautical miles ( 2, 493 km ) for the University of California, and resumed her North Pacific survey, making further gravimetric, magnetic field, bathythermograph, current, and meteorological observations and conducting underwater photography.
• "Pioneer " made another voyage to the North Pacific survey grounds later in the 1963 field season, calibrating her gravity meter, making gravimetric measurements, and experimenting with the design of Nansen bottles, bathythermograph collection speeds, the use of a thermoprobe at a depth of 9, 000 feet ( 2, 743 meters ) and the use of a sea sled to capture specimens.
• She completed the 1960 field season with operations off California, including the establishment of EPI and SHORAN stations on the coast to support offshore oceanographic work and involving use of a bathythermograph to make ocean surface temperature measurements for the United States Fish and Wildlife Services Bureau of Commercial Fisheries, drift measurements, the use of a towed magnetometer, oceanographic and atmospheric measurements at various locations, and the investigation by her survey launches of possible shoaling in San Francisco Bay.
