Consisting of smooth and gently sloping surfaces, prominent escarpments, knolls, intraslope basins, and submarine canyons and channels, it is an area of extremely diverse topographic and sedimentologic by: 4.

The Gulf of Mexico covers an area of more than 1,sq km, has a maximum depth of about 3,m, and includes many of the geomorphic features of large continental shelf, slope, rise, and abyssal plain comprise the major physiographic provinces of the guldf and contain avariety of subprovinces distinguished by topographic character and geomorphic history.

The hummocky continental slope in the northwestern Gulf of Mexico is the result of active salt tectonism and accompanying faulting. Fluid and gassy hydrocarbons rise through the sediment column and along faults causing the formation of gas hydrates, gassy sediments, mud volcanoes and mounds, chemosynthetic communities and authigenic carbonates, reefs, and by: Geochemical environments were characterized for 14 sites along the northern Gulf of Mexico continental shelf and upper slope, in an effort to examine the relationship between sediment geochemistry and carbonate shell taphonomy in a long-term study—Shelf and Cited by: 6.

The continental slope of the northern Gulf of Mexico margin (Texas–Louisiana slope) displays a bathymetrically complex morphology that terminates abruptly in the Sigsbee escarpment in the central Gulf, and is filled in by the head of the Mississippi fan to the east (Steffens et al., ).

The hallmark of the central Gulf continental slope is. The Orca Basin is a mid-slope, silled, mini-basin in the northern Gulf of Mexico some km southwest of the Mississippi River mouth on the Louisiana continental slope. It is unique amongst the mini-basins in this area, in containing a large brine pool of anoxic salt pool is approximately km 2 (47 sq mi) in area and up to m ( ft) deep under 2, m (7, ft) depth of.

The continental slope in the northern Gulf of Mexico has a very distinct appearance. Note the pock-marked nature in the water depths colored red in this bathymetric image below. The coastal area. At the same time, LGL Ecological Research Associates was conducting a research cruise as part of the multiyear MMS Northern Gulf of Mexico Continental Slope Study (Gallaway et al., ).

Clymene dolphins were seen in the winter, spring and summer during recent seasonal GulfCet aerial surveys of the northern Gulf of Mexico during (Davis et al.

Hydrocarbon-derived and microbially mediated authigenic carbonates occur over the entire depth range of the northern Gulf of Mexico slope. These carbonates consist of nodules and incipient nodules in surface sediments, hardgrounds and isolated slabs, and moundlike buildups of up to 10–20 m relief above the surrounding by: The Atlantic spotted dolphin is endemic to the Atlantic Ocean in warm temperate to tropical waters (Perrin et al.

Earle A continuation of the landmark scientific reference series from the Harte Research Institute for Gulf Of Mexico Studies, this volume provides the most up-to-date systematic, cohesive, and comprehensive description of the geology of the Gulf of Mexico basin.

Initial scientific investigations were slow to develop because the study of natural gas hydrates is unusually challenging. Gas hydrate exists in nature in conditions of temperature and pressure where human beings cannot survive, and if gas hydrate is transported from its region of stability to normal Earth-surface conditions, it dissociates.
