The Carbonate System
The sections look very similar. The results at the two sections were fit to the empirical
equation (Friis et al., 2005):
TCO 2 = const. + a σ θ + b θ + c S + d SiO 2 + e PO 4
(7.137)
where a, b, c, … are empirical constants. The differences between the equations for the two
sections are shown in Figure 7.53. These methods do not work too well in the mixed layers
