Over the course of 30 days or so, possibly less, about 93,000
cubic kilometers of water — almost 80 % of the volume of all free - flowing fresh water on Earth today — carved the 15 - km - wide, 2.5 - km -
deep Aram Valley.
In a further experiment, Böning and co-workers showed that a cumulative freshwater volume of ~ 20,000
cubic kilometers leads to a breakdown of
deep convection and a slowdown of the AMOC by 5 Sv within a few years.
