Deep water originating in the North Atlantic is transported across theAntarctic Circumpolar Current by eddies and enters the Weddell Gyresouth of Africa. As it does so it rises up from mid depth towards thesurface. The separate temperature and salinity maxima, the Upperand Lower Deep Waters, converge to form the Warm Deep Water.cores of this water mass on the southern flank of the Weddell Gyreshow a change in characteristic as they flow westward in the LazarevSea. Observations have been made along four meridional sections at3°E, 0°, 3°W and 6°W between 60 and 70°S during the PolarsternLAKRIS Cruise ANTXXIII/2 in December 2005.
