Intermediate Waters in the Irminger Sea during Deep Convection: Variability and the Role of Circulation Mechanisms

The spatial structure, interannual variability, and pathways of the Labrador Sea water (LSW) in the Irminger Sea were analyzed during period of deep convection in 2014–2017. Four regions of the LSW were distinguished, that characterized by different thermohaline properties and dissolved oxygen saturation. The regions showed synchronous variability and complied with the main circulation (the Irminger Current, Irminger Gyre, and the western boundary current system including the recirculation of the Irminger Current). The flowing-out LSW from the Irminger Sea is warmer by 0.17°C and more saline by 0.02 PSU than the flowing-in waters because of the mixing with the Irminger Current.
