Important ocean currents in the Atlantic may collapse. Scientists are racing to understand the dangers.

In addition, the research team usually conducts longer voyages every 18 months, removing and replacing sensors from three or four moorings on the east side of the Bahamas. Their British counterparts did the same work on the east side of the ocean and along the Atlantic ridge.

Other groups have set up a series of mooring equipment in different parts of the Atlantic Ocean to better understand how different components work, how closely the system is connected, and whether changes in a certain part have rippled throughout the process.

Susan Lozier, an oceanographer at the Georgia Institute of Technology, led an international project called OSNAP, which began in 2014. It has anchored the cable in the Labrador Sea, from the southeastern edge of Greenland to the coast of Scotland.

The hope of international research work is to go to the source of deep water sinking, which is mainly responsible for driving the ocean currents in the Atlantic Ocean, “trying to better understand the mechanism that drives AMOC changes,” Lozier said.

She said that so far, the monitoring program has largely found that changes in the Atlantic circulation have been greater than previously thought.

Its intensity and speed fluctuate drastically from month to month, year to year, and from region to region.Most of the deep water sank in the North Atlantic Seems to be happening Not in the Labrador Sea that has long been considered, but in the basin east of Greenland. The branches flowing north and south are more independent than previously understood. The local wind patterns seem to be more influential than expected. Some findings are just confusing.

The Atlantic circulation is likely to have weakened.Research by Ramstorf and others at the Potsdam Institute concludes About 15% slower Probably the weakest compared to the mid-20th century More than 1000 yearsBoth of these findings are based in part on long-term reconstructions of their behavior using records such as Atlantic temperature and seafloor particle size, which can reflect changes in deep ocean currents.

and”Strongly agree“In the model, if greenhouse gas emissions continue, ocean currents will continue to weaken this century.
