New discoveries in an international ocean observing network challenge the long-standing view that the greenhouse effect could delay much of the ocean’s “transport belt.” It is an overview of what regulates the power of the southern slope circulation of the Atlantic Ocean, a system of currents that redistribute heat around a large part of the western hemisphere.
The researchers believed that the power of this circulation, known as the AMOC acronym, was influenced by the sinking of fresh and cold water in the Labrador Sea, between Canada and Greenland. And climate simulations propose that the formation of deep-sea waters could slow if the world continues to heat up, which could also slow down the entire energy system of the Atlantic and eventually bring down temperatures in the northern areas comes from the United States and the United Kingdom. This concept inspired the 2004 film on the apocalypse of the climate, “The Day After Tomorrow”.
However, data collected during these 21 Months illustrate that the Labrador Sea’s power on AMOC is much lower than that of another part of the North Atlantic, east of Greenland. As the intensity of deepwater training in this region changed over time, it accounted for 88% of the variability observed throughout the AMOC, said Susan Lozier, a physical oceanographer at Duke University and his colleagues in Science.
The group has more than 55 moorings or sensor lines that are connected to the seabed along two major transects in which one is stretched from the Labrador Sea to West Greenland and the other stretched from east to Scotland.
Among one of the studies on climate change, A work presented by Thornalley stated that over the past 150 Years AMOC has been relatively feeble in contrast to last 1500 Years.
