Characterizing the Interannual Variability of North Atlantic Subpolar Overturning Open
Variability of the Atlantic Meridional Overturning Circulation (MOC) has drawn extensive attention due to its impact on the global redistribution of heat and freshwater. Here we present the latest time series (2014–2022) of the Overturning…

Can the Irminger Current impact restratification in the Irminger Sea?A Lagrangian model study on the fate of the Irminger Current water Open
The Irminger Sea is one of the few places in the North Atlantic where dense water masses are formed through deep convection. Next to atmospheric forcing, wintertime convection in the Irminger Sea interior can be impacted by the extent of r…

Recent Freshening of the Subpolar North Atlantic Increased the Transport of Lighter Waters of the Irminger Current From 2014 to 2022 Open
Starting in 2012, the eastern subpolar North Atlantic experienced the strongest surface freshening in the past 120 years. It is yet unknown whether this salinity anomaly propagated downward into the water column and affected the properties…

Where do the Two Cores of the Irminger Current Come From? A Lagrangian Study Using a 1/10° Ocean Model Simulation Open
The Irminger Current (IC) brings relatively warm and saline waters northward in the North Atlantic subpolar gyre, contributing to the upper limb of the Atlantic Meridional Overturning Circulation. The IC is a two‐core current with surface‐…

The Irminger Gyre as a Key Driver of the Subpolar North Atlantic Overturning Open
The lower limb of the Atlantic meridional overturning circulation (AMOC) is the equatorward flow of dense waters formed through the cooling and freshening of the poleward‐flowing upper limb. In the subpolar North Atlantic (SPNA), upper lim…

Freshening over the whole water column as a result of the 2012 subpolar freshwater anomaly increased the transport of lighter waters of the Irminger Current between 2014 - 2022 Open
The North Atlantic subpolar gyre experienced strong freshening in recent years starting around 2012. Here, we investigate the imprint of this freshwater anomaly on the water column hydrography and transport variability of the Irminger Curr…

Summer fresh layers and winter mixed layers in the western Subpolar Gyre Open
The strength of the Atlantic Meridional Overturning Circulation has been tied to deep convection in the subpolar North Atlantic. The depth of convection in winter, and the density of its product, depends on the balance between the water co…
