The dense waters formed by wintertime convection in the Labrador Sea play a key role in
setting the properties of the deep Atlantic Ocean. To understand how variability in their
production might affect the Atlantic Meridional Overturning Circulation (AMOC) variability, it
is essential to determine pathways and associated timescales of their export. In this study,
we analyze the trajectories of Argo floats and of Lagrangian particles launched at 53° N in
the boundary current and traced backward in time in a high‐resolution model, to identify and …
