    Surface transport of oil in the open ocean is governed by a multitude of physical and chemical processes (Spaulding, ; ASCE, ; Reed et al., ). Oil is advected by the surface currents associated with tides, river-ine discharge, oceanographic currents, meteorological forcing and breaking waves, and by direct wind forcing at the sea. Sea water temperature in some cities of Mexico is above 20°C/68°F and it is enough for comfortable bathing. The warmest sea temperature in Mexico today is 30°C/86°F, and the coldest sea temperature today is 15°C/59°F. The Loop Current is an extension of the western boundary current of the North Atlantic subtropical gyre. Serving as the dominant circulation feature in the Eastern Gulf of Mexico, the Loop Currents transports between 23 and 27 sverdrups and reaches maximum flow speeds of . (AMOC), leading to a subsequent slowing of Florida’s regional/local current systems (Yucatan, Loop, Florida and Gulf Stream) and eddies. While downscaled climate models suggest that slowing of the Loop Current by % during the 21 st century will moderate the increase in surface temperatures in the Gulf of Mexico to oC - oC, this.

    Surface dispersion properties in the southwestern Gulf of Mexico are studied by using a set of drifters released during a 7-yr period and tracked for 2 months on average. The drifters have a drogue below the surface Ekman layer, so they approximately follow oceanic currents. This study follows two different ap-.

The Northern Gulf of Mexico (NGOM) has been the site of several large observational programs involving measurements of ocean currents. A major goal for much of this work has been to develop a risk assessment for the NGOM involving oil spill spread by currents (Ohlmann and Niiler, ).

As a result of these programs, a rich. 4 LOOP CURRENT, RINGS AND RELATED CIRCULATION IN THE GULF OF MEXICO maps (e.g., website A. ; a good one is the seven-day compos-ite on 5 Februaryshown in Plate). These fine-scale features can dominate local circulation, especially in regions removed from direct impacts of the Loop Current and rings.

The Gulf Stream is a particularly strong current that carries warm water north from the Gulf of Mexico up the eastern coast of the United States and across the Atlantic to Western Europe. The Gulf Stream moves times more water than all the rivers on Earth combined and flows times faster than the Amazon – the world’s largest river.

In contrast to the Loop Current and rings, much less is known about deep eddies (deeper than m) of the Gulf of Mexico. In this paper, results from a high-resolution numerical model of the Gulf are analyzed to explain their origin and how they excite topographic Rossby waves (TRWs) that disperse energy to the northern slopes of the by: A parent to the Florida Current, the Loop Current is a warm ocean current that flows northward between Cuba and the Yucatán Peninsula, moves north into the Gulf of Mexico, loops east and south before exiting to the east through the Florida Straits and joining the Gulf Loop Current is an extension of the western boundary current of the North Atlantic subtropical gyre.

The Loop Current is an area of warm water that travels up from the Caribbean, past the Yucatan Peninsula, and into the Gulf of Mexico. The current is also known as the Florida current as it flows through the Florida Strait, into the Gulf Stream, and heads north up the eastern coast of the U.S.

The Gulf of Mexico (GOM) is a highly stratified basin whose dynamics largely follow those of a two-layer system. The upper layer (above – m) is characterized by surface-intensified flows, while the lower layer (> m to the bottom) shows currents that do not vary with depth (e.g., Hamilton ).The upper-layer circulation is dominated by the Loop Cited by: 4.

A detailed examination of the three-dimensional circulation associated with Loop Current rings in the Gulf of Mexico has been made using the Modular Ocean Model. About this book. In Circulation in the Gulf of Mexico, the current state of knowledge on circulation in the Gulf of Mexico is described through 22 papers at the forefront of view is selective rather than all-inclusive, with primary focus on circulation at the sea surface and at depth, including nearshore flow.

The Gulf of Mexico Loop current is an ocean current that transports warm water from the Caribbean Sea into the Gulf of Mexico. The current brings the warm water through the Florida Straits and to the west of the Bahamas, where it begins to. The Gulf of Mexico Loop Current may intrude far into the Gulf of Mexico or take a more direct entry to exit pathway.

The warm Gulf Stream originating in the tropical Caribbean, for instance, carries about times more water than the Amazon River. The current moves along the U.S. East Coast across the Atlantic Ocean towards Europe. The heat from the Gulf Stream keeps much of Northern Europe significantly warmer than other places equally as far north.

by the Gulf Stream, the currents in the Gulf of Mexico are dominated by the Loop Current. The Loop Current forms as the pre-Gulf Stream waters flow from the Caribbean Sea, through the Gulf of Mexico, and on into the Atlantic. The Loop Current is as strong as the Gulf Stream, but since the Gulf is only about one-fifth the width of the Atlantic, the.

Sea surface temperatures in the Gulf of Mexico rise due to natural summer warming. These warm surface temperatures are a contributing factor to favorable conditions that can lead to the formation of tropical storms and hurricanes in the Gulf of Mexico and off the East Coast of the United States.

In general, hurricanes tend to form over warm ocean water whose temperature. The eddy circulation over the northeastern Gulf of Mexico slope and the DeSoto canyon has been characterized using data from a 13 mooring array and 7 hydrographic surveys over a. The Gulf of Mexico is the ninth largest body of water in the world and contains over 15 percent of all known species of marine fishes.

This diverse fish fauna has been the subject of many publications, but, until now, no work has ever surveyed all known species, including the deep sea fishes and those of the southern Gulf.

In this book, we describe our current state of knowledge on circulation in the Gulf of Mexico through 22 papers at the forefront of research. The view is selective rather than all-inclusive, with primary focus on circulation at the sea surface and at depth, including nearshore flow.

The ocean circulation patterns of the Gulf of Mexico (GOM) Loop Current (LC) system and their effects on the advection of the oil discharged during the Deepwa-ter Horizon incident are described using in situ surface drifter trajectories and satellite observations from May to August These observations include.

Data from the ESA's Envisat radar satellite shows that the Gulf of Mexico Oil Spill has entered the Loop Current, a powerful conveyor belt that flows clockwise around the Gulf of Mexico towards Florida."With these images from space, we have visible proof that at least oil from the surface of the water has reached the current," said Dr Bertrand Chap.

The surface circulation of the Caribbean Sea and Gulf of Mexico is studied using 13 years of satellite altimetry data. Variability in the Caribbean Sea is evident over several time scales. At the annual scale, sea surface height (SSH) varies mainly by a seasonal steric effect. Interannually, a longer cycle affects the SSH.

Data from 17 PALACE floats set in the Gulf of Mexico sampling the intermediate-depth (∼ ∼ dbar) flow from April to February indicate a mean cyclonic circulation along the northern and western edges of the Gulf of Mexico. This flow intensified into a ∼ ∼ m/s current in the western Bay of Campeche and was deflected around.

The Gulf of Mexico (Spanish: Golfo de México) is an ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent.
