Figure 1. Monthly mean values of surface AT (mmol kg1
)
for August for the world’s ocean, as estimated from the
regional AT algorithms given in Table 1 applied to monthly
mean sea surface salinity (SSS) and temperature (SST) fields
(1latitude 1longitude) from the World Ocean Atlas 2001
[Conkright et al., 2002]. White lines represent the approximate
boundaries for the five different regions with unique
relationships of AT with SSS and SST and the numerical
numbers represent the five regions listed in Table 1. Crosses
denote locations of sampling stations.
