“…It takes 100–250 days from 90°W to 95°W with speeds of 2.14–5.32 km d −1 . Upon arrival at the western boundary, the strength of LCR rapidly weakens by the interaction with the slope at the western boundary of the Gulf of Mexico [ Vidal et al , 1999].…”

“… Sturges [1993] showed that a local wind stress curl does drive annual variations of the western boundary current. From hydrographic data, Vidal et al [1999] showed that a western boundary current was set up by the interaction of LCR with the slope of the western gulf, and this is the main forcing mechanism in the regional circulation. Figure 14 shows 6 year average current fields at the surface (Figure 14a) and at the 2000 m depth (Figure 14b) from the model results.…”

“…In this work, marine sediments from the North Coast of the Gulf of Mexico were analyzed in the frame of Environmental Program of the Faculty of Chemistry from the National University of Mexico [1]. Mexico's economic zone in the Gulf of Mexico's basin is around 0.9 9 10 6 km 2 , totaling 55 % of its total surface [2]. Since the end of the 1970 decade, Gulf of Mexico's oil industry has been the engine of economic development, in this region [3], followed by fishing, tourism and agriculture.…”

Sediments collected from the North Coast of the Gulf of Mexico got carefully mixed, dried, and finally subjected to physical and chemical analysis. Metal concentration was determined by energy dispersive X-ray fluorescence (EDXRF). Sequential chemical analysis was performed by modified TESSIER technique. Results and statistical analysis (a = 0.05) show concentrations of most elements (excepting Mn, Ca, Ga, As and Pb) in the range of those of the earth crust's values, which set a sampling zone base line. Sequential extraction shows the potential risk of mobilization of metals sequestered in particulate phases by oxidation of anoxic sediments or intense organic matter degradation.

This study examines potential marine modification of two classes of terrestrial influence on Gulf hypoxia: (1) the flow of nutrient-rich water from the Mississippi/Atchafalaya River Basin and (2) the massive physical, hydrological, chemical and biological change associated with the Atchafalayas partial capture of the Mississippi River. The latter involves repartitioning of a total flow of about 20 000 m 3 sec 1 , equal to that of 13 Nile Rivers, and a sediment load of 210 million metric tonnes yr 1 ,nearly 20 times that delivered by all of the rivers of the East Coast of the USA. Also involved is the loss of hundreds-to-thousands of years of stored nutrients and organic matter to the Gulf from enormous coastal wetland loss. This study found that the oceanography of the Gulf minimises the impact of both classes of terrestrial influence from the Mississippi River and its nearby estuaries on Gulf hypoxia. Oceanographic conditions give events associated with the Atchafalaya River a disproportionately large influence on Gulf hypoxia. A truly holistic environmental approach which includes the full effects of this highly dynamic coastal area is recommended to better understand and control Gulf hypoxia.
