Louisville Ridge
The Louisville Ridge, also known as the Louisville Seamount Chain, is an underwater chain of over 70 seamounts located in the Southwest portion of the Pacific Ocean.

Louisville Seamount Chain - Bathymetry
Louisville ( , , ) is the largest city in the Commonwealth of Kentucky and the 28th most-populous city in the United States. Louisville is the historical seat and, since 2003, the nominal seat of Jefferson County, on the Indiana border. Named after King Louis XVI of France, Louisville was founded in 1778 by George Rogers Clark, making it one of the oldest cities west of the Appalachians. With nearby Falls of the Ohio as the only major obstruction to river traffic between the upper Ohio River and the Gulf of Mexico, the settlement first grew as a portage site. It was the founding city of the Louisville and Nashville Railroad, which grew into a system across 13 states. Today, the city is known as the home of boxer Muhammad Ali, the Kentucky Derby, Kentucky Fried Chicken, the University of Louisville and its Cardinals, Louisville Slugger baseball bats, and three of Kentucky's six ''Fortune'' 500 companies: Humana, Kindred Healthcare, and Yum! Brands. Muhammad Ali Internat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seamounts Of The Pacific Ocean
A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RV Sonne
The RV'' Sonne'' (German for 'Sun') was a former German fishing trawler converted into a research vessel by Schichau Unterweser AG, doing mostly geoscience-related work for a variety of commercial and scientific clients. She was registered in Bremen. In 2015 she was sold to the Argentine institute CONICET and was renamed ARA ''Austral'' (Q-21). A new geoscientific research ship, also called RV ''Sonne'', replaced her role in Germany that same year. Career Rickmers Werft built ''Sonne'' in 1969 as a stern trawler and delivered her to ''Hochseefischerei Nordstern''. From her homeport of Bremerhaven she operated mainly in the waters around Iceland, Greenland and Labrador. ''Sonne'' was converted for use in a scientific exploration role by Schichau Unterweser AG in 1977 and by Rickmers Werft in 1978. In 1991 Schichau-Seebeck-Werft lengthened and modernized her. An order worth €124.4 million for a new geoscientific research ship was placed by the German federal ministry for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Ocean Drilling Program
The Integrated Ocean Drilling Program (IODP) was an international marine research program. The program used heavy drilling equipment mounted aboard ships to monitor and sample sub-seafloor environments. With this research, the IODP documented environmental change, Earth processes and effects, the biosphere, solid earth cycles, and geodynamics. The program began a new 10-year phase with the International Ocean Discovery Program, from the end of 2013. Navigating the route to discovery Scientific ocean drilling represented the longest running and most successful international collaboration among the Earth sciences. Scientific ocean drilling began in 1961 with the first sample of oceanic crust recovered aboard the ''CUSS 1'', a modified U.S. Navy barge. American author John Steinbeck, also an amateur oceanographer, documented Project Mohole for LIFE Magazine. Legacy programs The Deep Sea Drilling Project (DSDP), established in June 1966, operated the ''Glomar Challenger'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hotspot (geology)
In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. Examples include the Hawaii, Iceland, and Yellowstone hotspots. A hotspot's position on the Earth's surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them. There are two hypotheses that attempt to explain their origins. One suggests that hotspots are due to mantle plumes that rise as thermal diapirs from the core–mantle boundary. The alternative plate theory is that the mantle source beneath a hotspot is not anomalously hot, rather the crust above is unusually weak or thin, so that lithospheric extension permits the passive rising of melt from shallow depths. Origin The origins of the concept of hotspots lie in the work of J. Tuzo Wilson, who postulated in 1963 that the formation of the Hawaiian Islands resulted from the slow movement of a tecton ...

Hollister Ridge
Hollister Ridge is a group of seamounts in the Pacific Ocean. They lie west from the Pacific-Antarctic Ridge and form three ridges that form a line; one of the ridges rises to a depth of and in the past formed an island. The seamounts are composed out of basaltic and other rocks and their ages range from about 2.5 million years ago to latest Pleistocene; an acoustic swarm recorded in the southern Pacific Ocean in 1991-1992 is considered to be the manifestation of a historical eruption of the Hollister Ridge. The origin of the Hollister Ridge is unclear, with various proposed mechanisms involving the neighbouring Pacific-Antarctic Ridge, crustal weaknesses and the Louisville hotspot. History The ridge was discovered either by gravimetry from satellites or by the research ship '' Eltanin'' in 1965 and first named "Hollister Ridge" in a 1995 publication. Rock samples were taken at the ridge in 1996. Geography and geomorphology The Hollister Ridge is an aseismic ridge in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seafox Seamount
The Fairey Seafox was a 1930s British reconnaissance floatplane designed and built by Fairey for the Fleet Air Arm. It was designed to be catapulted from the deck of a light cruiser and served in the Second World War. Sixty-six were built, with two finished without floats and used as landplanes. Design and development The Fairey Seafox was built to satisfy Air Ministry Specification S.11/32 for a two-seat spotter-reconnaissance floatplane. The first of two prototypes appeared in 1936, first flying on 27 May 1936,Taylor 1974, p.285. and the first of the 64 production aircraft were delivered in 1937.Taylor 1974, p.287. The flights were organised as 700 Naval Air Squadron of the Fleet Air Arm. The fuselage was of all-metal monocoque construction, the wings being covered with metal on the leading edge, otherwise fabric. It was powered by a 16-cylinder 395 hp (295 kW) air-cooled Napier Rapier H engine. It cruised at 106 mph (171 km/h), and had a range of 4 ...
