Short summary
The Iceland–Scotland Overflow Water is a dense water carried within the lower limb of the Atlantic Meridional Overturning Circulation. From a combination of ship-based and Deep-Argo data gathered between 2015 and 2018, our study analyzes the pathways and evolution of its properties as it flows through a main fracture of the Reykjanes Ridge, the Bight Fracture Zone (BFZ). We show that 0.8 ± 0.2 Sv of ISOW flows through the BFZ and is mainly homogenized within the rift valley of the ridge.
