Particulate barium was analysed in the upper 600 m of the Southern Ocean water column during repeated transects along the 6 degree W meridian in October-November 1992. The transects extended between the northern edge of the Weddell Gyre (57 degree 30'S) in the south to 47 degree S within the Polar Front Zone (PFZ) in the north. From earlier studies, it is known that the largest fraction of Ba in oceanic suspended matter occurs as barite micro-crystals. In the PFZ, an increase in the particulate Ba content in surface waters and at mesopelagic depths can be significant over the investigation period (1 month) and follows the increase of primary production during bloom development. Using an inverse one-dimensional advection-diffusion-consumption model,...
