(September 2002, dotted lines). The x axis shows the time (h) of the transect with t = 0 at the north end point 65 ° W, 55 ° S to t = 44 h at the southern point 62 ° S. On average March temperatures are 2.94° ± 0.03 ° C warmer than September temperatures ( Fig. 4 ), but the SST gradient is sharper around the Polar Front in September compared to March when the cold Antarctic surface water is capped by summer heating. Temperatures in March and September for the whole data period are presented in Fig

ocean heat gain ( Fig. 13a ). The net evaporation in this latitude band ( Fig. 13c ) acts to decrease buoyancy (increase density) ( Fig. 13e ). Between about 40° and 60°S, net heating and freshwater input act together to increase buoyancy (reduce surface density) in all of the products. The heat and freshwater flux estimates differ most south of 60°S ( Figs. 13b,d,f ) since here the estimates are mostly numerical model results owing to the sparseness of observations ( Kalnay et al. 1996 ; Röske
