The terms international waters or transboundary waters apply where any of the following types of bodies of water (or their drainage basins) transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed regional seas and estuaries, rivers, lakes, groundwater systems (), and wetlands. Second, as rifting progressed through Early and Middle Jurassic times, the continental crust was stretched and thinned. The moving salt fractured and faulted the overlying brittle sediments, in turn creating natural pathways for deep oil and gas to seep upward through the cracks and form reservoirs within shallower geologic layers [Buffler and Sawyer, 1985; Hudec et al., 2013]. The Gulf of Mexico consists of several ecological and geologic provinces, chief of which are the coastal zone, the continental shelf, the continental slope, and the abyssal plain. Oyster shells obtained from the shallow waters are used in the chemical industry as a source of calcium carbonate and also provide material for building roads. [27] River drainage and atmospheric fallout from industrial coastal cities also provide nutrients to the coastal zone. Offshore spreading of Mississippi waters: pathways and vertical structure under eddy influence. Which Waters Do You Pass Through When You Sail the Seven Seas? On July 30, 1942, the Robert E.

[19] Seven main areas are given as:[citation needed]. [20] The first alleged European exploration of the Gulf of Mexico was by Amerigo Vespucci in 1497.
