Figure 7. Annual mean of the surface outcrop areas [X10'! m”] represented by the gray bars for each isopycnal bin from (a) 69=275kg m” to (e) 69=27.1kg m” 
compared to the respective temperatures [°C] (blue lines), salinity (black lines) and winter (JFM) MLDs [m] (orange lines) within the outcrop area at the time when the 
ısopycnals outcrop at the surface. Purple and green bars highlight the vears used to calculate the composites 1 and 2 shown in Figure 9. 
Atlantic. Consequently, there was an increased propagation of freshwater from the western boundary into the 
eastern basin. In a more recent study, Bilö et al. (2022) referred to this freshening as the “new great salinity 
anomaly” (GSA), which arrived in the Irminger Sea between 2015 and 2020. This GSA contributed to the 
suppression of the deep convection in the Irminger Sea in the subsequent winters after 2018. Bilö et al. (2022)
