Antarctic meltwater is projected to slow the abyssal cell

node

Li, England, Hogg, Rintoul and Morrison published modelling work in Nature indicating that meltwater from Antarctica, by freshening the shelf water from which Antarctic Bottom Water forms, drives a substantial slowdown and warming of the abyssal overturning circulation. Observational context points the same way: Weddell Sea Bottom Water volume has fallen by around 30 per cent since 1992, with the densest classes lost fastest.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
