TL;DR: It is shown, through the analysis of long hydrographic records, that the system of overflow and entrainment that ventilates the deep Atlantic has steadily changed over the past four decades, and this changes have already led to sustained and widespread freshening of the deep ocean.

TL;DR: A comparison of salinities on a long transect through the western basins of the Atlantic Ocean between the 1950s and the 1990s is presented, suggesting shifts in the oceanic distribution of fresh and saline waters are occurring worldwide in ways that suggest links to global warming and possible changes in the hydrologic cycle of the Earth.

TL;DR: The Labrador Sea has exhibited significant temperature and salinity variations over the past five decades as discussed by the authors, and the main process responsible for the net cooling and freshening of the Labrador Sea between 1987 and 1994 was deep winter convection, which during this period progressively developed to its record depths.

TL;DR: It is suggested that the conversion of warm, salty, shallow Atlantic waters into colder, fresher, deep waters that move southward in the Irminger and Iceland basins is largely responsible for overturning and its variability in the subpolar basin.

TL;DR: In this paper, a 4-year period of exceptionally intense convection followed by 5 years of restratification was observed across the central Labrador Sea in the early summers between 1990 and 2000.
