Roger Clive Searle
Roger Clive Searle (born 24 October 1944 in St Ives, Cambridgeshire, St Ives, Huntingdonshire, died 26 November 2024, Northumberland) was an English geophysicist, known for using Side-scan sonar, sonar imaging in research on the geology and geophysics of the ocean floor. In particular, he has made important contributions to understanding the Seafloor spreading, oceanic spreading system and the Seafloor spreading#Spreading center, mid-ocean spreading centres. Biography Searle graduated from the University of Cambridge with a B.A. (with a major in physics) in 1966 and an M.A. in 1970. He received a PhD in geophysics from the Newcastle University, University of Newcastle upon Tyne in 1969. He was from 1970 to 1973 an assistant professor at Haile Selassie University in Addis Ababa. At the Institute of Oceanographic Sciences in Wormsley Park, Searle was a senior science officer from 1973 to 1978; a principal science officer, Civil Service (United Kingdom)#Grading schemes, civil service ...

St Ives, Cambridgeshire
St Ives is a medieval market town and civil parishes in England, civil parish in the Huntingdonshire district of Cambridgeshire, England. It is located on the River Great Ouse, and there is St Ives Bridge, a historic stone bridge dating from 1425. The bridge has an unusual chapel incorporated into the structure. The nearby Quayside offers pleasing views of the river and the bridge. The settlement was known at first as Slepe: it was at a convenient Ford (crossing), fording point on the river, which encouraged the establishment of a route for travellers between northern and eastern districts of the country, and London and the South, enhancing its importance. A little before the year 1000 CE, a coffin was dug up during ploughing: it apparently contained the remains of a holy man named Ivo of Ramsey, and as a result the town became a destination for pilgrims, and the name Slepe was changed over time to St Ives. A royal charter authorised the holding of a fair in the town; at the ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tectonic Plates
This is a list of tectonic plates on Earth#Surface, Earth's surface. Plate tectonics, Tectonic plates are pieces of Earth's crust and uppermost mantle (geology), mantle, together referred to as the lithosphere. The plates are around thick and consist of two principal types of material: oceanic crust (also called ''Sima (geology), sima'' from silicon and magnesium) and continental crust (''sial'' from silicon and aluminium). The composition of the two types of crust differs markedly, with mafic basaltic rocks dominating oceanic crust, while continental crust consists principally of lower-density felsic granite, granitic rocks. Current plates Geologists generally agree that the following tectonic plates currently exist on Earth#Surface, Earth's surface with roughly definable boundaries. Tectonic plates are sometimes subdivided into three fairly arbitrary categories: ''major'' (or ''primary'') ''plates'', ''minor'' (or ''secondary'') ''plates'', and ''microplates'' (or ''tertiary ...

Reykjanes Ridge
The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian plate and the African plate, north and south of the Azores triple junction. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet triple junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about per year. Discovery A ridge under the northern Atlantic Ocean was first inferred by Matthew Fontaine Maury in 1853, based on soundings by the USS ''Dolphin''. The existence of the ridge and its extensio ...

Bathymetry
Bathymetry (; ) is the study of underwater depth of ocean floors ('' seabed topography''), river floors, or lake floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. The first recorded evidence of water depth measurements are from Ancient Egypt over 3000 years ago. Bathymetry has various uses including the production of bathymetric charts to guide vessels and identify underwater hazards, the study of marine life near the floor of water bodies, coastline analysis and ocean dynamics, including predicting currents and tides. Bathymetric charts (not to be confused with '' hydrographic charts''), are typically produced to support safety of surface or sub-surface navigation, and usually show seafloor relief or terrain as contour lines (called '' depth contours'' or '' isobaths'') and selected depths ('' soundings''), and typically also provide surface navigational information. Bathymetric maps (a more general term where navigational safet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Environment Research Council
The Natural Environment Research Council (NERC) is a British Research Councils UK, research council that supports research, training and knowledge transfer activities in the environmental sciences. History NERC began in 1965 when several environmental (mainly geographic) research organisations (including Nature Conservancy (UK), Nature Conservancy which became the Nature Conservancy Council in 1973 and was divided up in 1991) were brought under the one Umbrella organization, umbrella organisation. When most research councils were re-organised in 1994, it had new responsibilities – Earth observation and science-developed archaeology. Collaboration between research councils increased in 2002 when Research Councils UK was formed.

British Mid-Ocean Ridge Initiative
The British Mid-Ocean Ridge Initiative (the BRIDGE Programme) was a multidisciplinary scientific investigation of the creation of the Earth's crust in the deep oceans. It was funded by the UK's Natural Environment Research Council ( NERC) from 1993 to 1999. Mid-Ocean ridges Mid-Ocean ridges are active volcanic mountain ranges snaking through the depths of the Earth's oceans. They occur where the edges of the Earth's tectonic plates are separating, allowing mantle rock to rise to the seafloor and harden, creating new crust. The addition of this crust can cause ocean basins to widen perpendicular to the ridge. This seafloor spreading is the engine of continental drift. At intervals along the mid-ocean ridges super-heated mineral-rich fluids are vented from the seabed. These hydrothermal vents are populated by animal and bacterial species not found elsewhere on Earth. BRIDGE investigated the geological setting of the ridge, the geochemistry of vent fluids, and ways in which biol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
