Risk of global climate change by bp oil spill

This reads like a science fiction novel but the credentials of the laboratories involved are very credible.

I have a few questions:

How do they know this is the first time that the Gulf Stream Loop current has ever broken down anywhere along the current? How far back does their "past years data" go?

If it is not the first time, then what have been the natural forces that have restored the current?

When is their next report on this issue published?
 
Re: Risk of global climate change by bp oil spill

some very good (and current) satellite imagery here;

This picture taken on July 20 still shows the detached bud of the loop current (where the line density is highest).

There is still some flow between the bud and the loop current.

Can compare animations of loop data with previous years here;

Re: Risk of global climate change by bp oil spill

According to Wikipedia:

Part of the Gulf Stream, the Loop Current is a warm ocean current in the Gulf of Mexico that flows northward between Cuba and the Yucat?n peninsula, moves north into the Gulf of Mexico, loops west and south before exiting to the east through the Florida Straits.

A related feature is an area of warm water called an "Eddy" or "Loop Current ring" that separates from the Loop Current, somewhat randomly. These rings then drift to the west at speeds of about 5 cm/s (0.18 km/h or 0.11 mph) and bump into the coast of Texas or Mexico.

Around 1970, it was believed that the Loop Current exhibited an annual cycle in which the Loop feature extended farther to the north during the summer. Further study over the past few decades, however, has shown that the extension to the north (and the shedding of eddies) does not have a significant annual cycle.
