Sigsbee Deep
The Sigsbee DeepThe name "Sigsbee Deep" has sometimes been applied to Sigsbee Basin, a U. S. Board on Geographic Names approved name for a feature nominally a42° 58' 00" N 069° 13' 00" Win the Gulf of Maine. See multiple features named for Sigsbee a (Mexico basin in the U. S. Board on Geographic Names Advisory Committee on Undersea Features (ACUF) Gazetteer), is a roughly triangular basin that is the deepest part of the Gulf of Mexico named for Commander Charles Dwight Sigsbee, USN, Assistant U. S. Coast and Geodetic Survey, commanding officer of the USC&GS George S. Blake which discovered the feature during its mapping of the Gulf of Mexico. As described below there is some confusion of names that apply to the basin or a particular point in the basin with both being found in technical and popular literature applying to both basin and the coordinates. Description The basin is located in the southwestern quadrant of the Gulf, with its closest point to the U.S. coast at sou ...

Basin (geology)
In geology, a depression is a landform sunken or depressed below the surrounding area. Depressions form by various mechanisms. Types Erosion-related: * Blowout: a depression created by wind erosion typically in either a partially vegetated sand dune ecosystem or dry soils (such as a post-glacial loess environment). * Glacial valley: a depression carved by erosion by a glacier. * River valley: a depression carved by fluvial erosion by a river. * Area of subsidence caused by the collapse of an underlying structure, such as sinkholes in karst terrain. * Sink: an endorheic depression generally containing a persistent or intermittent (seasonal) lake, a salt flat (playa) or dry lake, or an ephemeral lake. * Panhole: a shallow depression or basin eroded into flat or gently sloping, cohesive rock.Twidale, C.R., and Bourne, J.A., 2018Rock basins (gnammas) revisited.''Géomorphologie: Relief, Processus, Environnement,'' Vol. 24, No. 2.

Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexico, Mexican States of Mexico, states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern United States, Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific Ocean, Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.

Charles Dwight Sigsbee
Charles Dwight Sigsbee (January 16, 1845 – July 13, 1923) was a rear admiral in the US Navy. In his earlier career, he was a pioneering oceanographer and hydrographer. He is best remembered as the captain of , which exploded in Havana Harbor, Cuba, in 1898 and set off the events that led up to the start of the Spanish–American War. Early life Sigsbee was born in Albany, New York, and educated at The Albany Academy. He was appointed acting midshipman on 16 July 1862.

Sigsbee served aboard , , and from 1863 to 1869, when he was assigned to duty at the Naval Academy. In 1871, he was assigned to the Hydrographic Office. He was first posted to the Hydrographic Office in 1873. He was assigned to the Coast Survey in 1874 and commanded the Coast Survey steamer ''Blake'' from 1875 to 1878.

USC&GS George S
The National Geodetic Survey (NGS) is a United States federal agency that defines and manages a national coordinate system, providing the foundation for transportation and communication; mapping and charting; and a large number of applications of science and engineering. Since its foundation in its present form in 1970, it has been part of the National Oceanic and Atmospheric Administration (NOAA), of the United States Department of Commerce. History The National Geodetic Surveys history and heritage are intertwined with those of other NOAA offices. It traces its history to the Survey of the Coast, which was formed in 1807 as the first scientific agency of the United States Government. It became the United States Coast Survey in 1836 and the United States Coast and Geodetic Survey in 1878, the latter name change reflecting the increasing role of geodesy in its work. Upon the creation of NOAA in 1970, the Coast and Geodetic Survey was abolished and its responsibilities were spl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Bathymetric Chart Of The Oceans
The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world’s oceans for scientists and others. Organisation GEBCO operates under the joint auspices of the International Hydrographic Organization (IHO). and the Intergovernmental Oceanographic Commission (IOC) of UNESCO. Its work is done by an international group of experts in seafloor mapping who develop a range of bathymetric data sets and data products. Data sets and products Although originally GEBCO published paper contour charts, today it has moved into the digital age and collects digital depths of the ocean from wherever they are available. GEBCO provides a range of bathymetric data sets and data products, including: *Global gridded bathymetric data sets: **GEBCO_08 G ...

Sigsbee Escarpment
The Sigsbee Escarpment is a major bathymetric feature of the Gulf of Mexico, extending for about . It separates the lower continental slope of the northern gulf from the abyssal plain of the Sigsbee Deep and has up to of relief across it. It has formed as a result of salt tectonics, due to the effects of loading of a thick layer of Jurassic halite ( Louann Salt) by Upper Jurassic to Cenozoic sedimentary rock Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation.
