This leg is a "fill-in" transect. It starts off in a north eastward direction for about 50 km (see the cruise track). At that point it became clear that it would take days to tow the Seasoar into a region of surface temperatures above 13° - 14°C. We decided to turn south eastward instead and look for the cold side of the STF. Satellite information suggested more pronounced SST gradients east of 130°E.
The leg remains entirely on the cold (subpolar) side of the STF. Its most notable feature is again the presence of inversions in the depth range 120 - 220 m which are fully density compensated.
