The latest satellite data establishes that the North Atlantic Current (also called the North Atlantic Drift) no longer exists and along with it the Norway Current. These two warm water currents are actually part of the same system that has several names depending on where in the Atlantic Ocean it is. The entire system is a key part of the planet's heat regulatory system; it is what keeps Ireland and the United Kingdom mostly ice free and the Scandinavia countries from being too cold; it is what keeps the entire world from another Ice Age. This Thermohaline Circulation System is now dead in places and dying in others.
This 'river' of warm water that moves through the Atlantic Ocean is called, in various places, the South Atlantic Current, the North Brazil Current, the Caribbean Current, the Yucatan Current, the Loop Current, the Florida Current, the Gulf Stream, the North Atlantic Current (or North Atlantic Drift) and the Norway Current.
The thermohaline circulation is sometimes called the ocean conveyor belt, the great ocean conveyor, or the global conveyor belt.
It is a university level physics experiment to use a tub of cool water and inject a colored stream of warm water into it. You can see the boundary layers of the warm water stream. If you add oil to the tub it breaks down the boundary layers of the warm water stream and effectively destroys the current vorticity . This is what is happening in the Gulf of Mexico and in the Atlantic Ocean.
The entire 'river of warm water' that flows from the Caribbean to the edges of Western Europe is dying due to the Corexit that the Obama Administration allowed BP to use to hide the scale of the BP Deepwater Horizon Oil Disaster. The approximately two million gallons of Corexit, plus several million gallons of other dispersants, have caused the over two hundred million gallons of crude oil, that has gushed for months from the BP wellhead and nearby sites, to mostly sink to the bottom of the ocean. This has helped to effectively hide much of the oil, with the hopes that BP can seriously reduce the mandated federal fines from the oil disaster. However, there is no current way to effectively 'clean up' the bottom of the Gulf of Mexico, which is about half covered in crude oil. Additionally, the oil has flowed up the East Coast of America and into the North Atlantic Ocean, and there is no way to effectively clean up this 'sea bottom oil'. It is likely, based on numerous reports, that the oil is still flowing in massive amounts from multiple places on the seabed floor. This effectively means, that even if we had the technology in place to somehow clean up the free flowing thick crude oil deep in the ocean, it would likely not be enough to reverse the damage to the Thermohaline Circulation System in the Atlantic Ocean.
