- Аннотация: Labrador Sea Water (LSW) has been very well monitored throughout the decades concerning temporal evolution of water mass properties or variability in its formation. In recent years several persistent LSW classes have been identified which result from time-varying convection in the Labrador Sea. Since the end of the 1990s the production of LSW switched from high-density to low-density classes, associated with an overall decline of the LSW formation rate. We review the formation history of these two LSW classes for the period 1987-2007 and put particular focus on spreading pathways of LSW in the interior North Atlantic. When combing hydrographic data with time series derived from moorings we find high levels of meso-scale variability related to intense eddy activity which is overlaying an interannual evolution. Cross-frontal exchange of the boundary current with the North Atlantic Current close to Flemish Cap causes the latter to be the main distributor of LSW types into the interior western subpolar North Atlantic. The results indicate a southward spreading of LSW along the Mid-Atlantic Ridge. http://www.aslo.org/orlando2008/files/2008osm-abstracts.pdf
