North Atlantic Deep Water Formation in the Labrador Sea

WitrynaNorth Atlantic Deep Water (NADW) is a water mass that is central to the oceanography of the deep Atlantic, the global meridional overturning circulation (MOC), and the climate of the Earth itself. The subpolar Atlantic is an especially important place for these phenomena because of the large changes wrought on NADW in these basins. Witrynathe NADW formation at the Nordic Seas have been closely related to the global climate [Böhm et al., 2015]. Thus, it is expected that changes in the ISOW, that is changes in …
