Refimprove date June 2009 Image Romanche Trench.jpg right 300px The RomancheTrench , also called the Romanche Furrow or Romanche Gap , is the third deepest of the major oceanic trenchtrench es of the Atlantic Ocean , after the Puerto Rico Trench and the South Sandwich Trench . It bisects the Mid Atlantic Ridge just north of the equator at the narrowest part of the Atlantic between Brazil and West Africa, extending from 2 N to 2 S and from 16 W to 20 W. The trench has been formed by the actions of the Romanche Fracture Zone , a portion of which is an active transform boundary offsetting sections of the Mid Atlantic Ridge. It is situated between the Sierra Leone Basin to the north northeast, the South Atlantic Basin to the east southeast, the Northern Brazilian Basin to the south southwest, and North Atlantic Ridge to the west northwest. Geologically, it is at the seam of the South American Plate to the West and the African Plate to the East. The trench has a depth of 7,760 m, is 300 km long and has an average width of 19 km and allows for a major circulation of deep ocean basin water from the west Atlantic to the east Atlantic basins. Deep water flow through the trench is from west to east with a rate of 3.6 10 sup 6 sup m s of 1.57 C water. ref Schlitzer, Reiner, et al. 1985 A meridional sup 14 sup C and sup 39 sup Ar section in northeast Atlantic deep water Journal of Geophysical Research, Volume 90, Issue C10, p. 6945 6952 http adsabs.harvard.edu cgi bin nph bib query?bibcode 1985JGR....90.6945S& db key PHY& data type HTML& format ref References Reflist External links http channel.nationalgeographic.com episode drain the ocean 3639 Overview tab Photos 18 ixzz0S5SEyE8F Drain the Ocean Computer generated image view over airplane flying across the Romanche ... of the Atlantic Ocean marine geo stub de Romanchegraben fr Fosse Romanche hi pl Kraw d Romanche ro Groapa Romanche fi Romanchen hauta zh ... more details

unreferenced date March 2008 The Tethyan Trench was an ancient oceanic trench that existed in the northern part of the Tethys Ocean during the middle Mesozoic to early Cenozoic era s. Geology The Tethyan Trench formed when the Cimmerian Plate was subduct ing under eastern Laurasia , around 200 million years ago, in the Early Jurassic . The Tethyan Trench extended at its greatest during Late Cretaceous to Paleocene , from what is now Greece to the Western Pacific Ocean . Subduction at the Tethyan Trench probably caused the continents Africa and India to move towards Eurasia , which resulted in the opening of the Indian Ocean. When the Arabian Plate Arabian and Indian plate s continental collision collided with Eurasia, the Tethys Ocean and the trench closed. Remnants of the Tethyan Trench can still be found today in Southeastern Europe and southwest of Southeast Asia .

Unreferenced date December 2006 Trench shields are steel or aluminum structures used for protecting utility worker s while performing their duties within a trench . They are customarily constructed with sidewalls of varying thicknesses held apart by steel or aluminum spreaders. Spreaders can be interchanged to match the width of the trench. The different materials and building designs lead to a variety of depth ratings, i.e. the depth of a trench that the shield can withstand a collapse without buckling. Depth ratings are determined by registered professional engineer s. A shield should not be confused with a shore. While they may serve the same function, trench shoring is a different physical application that holds up the walls of a trench to prevent collapse.

File Sbh s600.JPG thumb File Sbh s780.JPG thumb Trench shoring is the process of bracing the walls of a trench in order to prevent collapse. The phrase can also be used as a noun to refer to the materials used in the process. Several methods can be used to shore up a trench. Hydraulic shoring is the use of hydraulic piston s that can be pumped outward until they press up against the trench walls. They are typically combined with steel plate or a special heavy plywood called Finform. Another method is called beam and plate, in which steel I beam s are driven into the ground and steel plates are slid in amongst them. A similar method that uses wood planks is called soldier boarding. Hydraulics tend to be faster and easier the other methods tend to be used for longer term applications or larger excavations. Shoring should not be confused with shielding by means of trench shield s. Shoring is designed to prevent collapse, whilst shielding is only designed to protect workers should collapse occur.
