The Labrador Sea of the North Atlantic is one of a handful of oceanic regions where 'deep' or 'intermediate' convection occurs - i.e. where the wintertime surface cooling results in convective mixing to depths of more than 1000 m. This results in the formation of Labrador Sea Water, a relatively fresh intermediate water which spreads at mid-depth throughout much of the N. Atlantic and that is part of the North Atlantic Deep Water.
Heat and Freshwater Through The Labrador Sea
We have used a variety of data sources and atmospheric products to investigate the transformation process and its variability. In particular, we focused on the period from 1969 to 1972 when convection in the Labrador Sea ceased due to a rapid freshening of the surface waters and, also, due to a series of mild winters.
