Fig. 6: Evolution of Labrador Sea Water (LSW) thickness anomalies.
From: Decadal changes in Atlantic overturning due to the excessive 1990s Labrador Sea convection
a–d Layer thickness anomaly (relative to January 1983 in the filtered time series) of the dense class of LSW renewed in experiment CTRL during the intense 1990s convection period, for the five stations denoted in Fig. 5. The evolution in CTRL (continuous lines) is contrasted with experiment SENS (dash-dotted) which lacks the thickness peak in the 1990s. a The anomaly just south of the main convection area (pos. 1) is shown in comparison to the observational product of ref. 25 (dotted line). d The evolution of the LSW anomaly in the boundary current (pos. 5; black lines) is shown along with the overturning transport at FULL (grey lines) for both CTRL and SENS.
