Fig. 5: Spreading of the Labrador Sea density anomaly.
From: Decadal changes in Atlantic overturning due to the excessive 1990s Labrador Sea convection
Potential density anomaly a in experiment CTRL and b in experiment SENS averaged over the period 1990–1995 at 1500 m depth (σ0; kg m−3; colour shading) with the positions of stations (white stars) for which time series are shown in Fig. 6. The positions 1, 2, 3, and 5 correspond to moorings of the observational programme OSNAP (K1, K9, M5 and M1, respectively); position 4 represents a site near the origin of the deep western boundary current in the northern Irminger Basin, about 250 km south of Denmark Strait. c Depiction of the current field responsible for the advective spreading of water from the Labrador Sea into the Irminger Sea in CTRL, with a schematic accentuation of the main pathway.
