Figure 2: Monthly zonal average timeseries for the period January 1993 - December 1998 (cycles 11-232) of TOPEX-derived gas transfer velocity (k660) computed on a 2.5 x 2.5 degree grid. Values are in units of cm/h for Schmidt number Sc=660 (Sc=660 for CO2 at 20°C in seawater). The minimum value (the darkest purple) is approximately 5 cm/h.
