K.4 Silicate

The WQ Module allows for phytoplankton to uptake silicate to meet primary production demands, for phytoplankton groups that require silicate. Silicate uptake is calculated as per Equation (K.9).

\[\begin{equation} F_{Si-uptake}^{phy} = R_{prod\langle computed\rangle}^{phy} \times \left[PHY\right] \times X_{Si-C-con}^{phy} \tag{K.9} \end{equation}\]

\(F_{Si-uptake}^{phy}\) is the uptake of silicate, \(R_{prod\langle computed\rangle}^{phy}\) is the computed primary productivity rate, \(\left[PHY\right]\) is a computational cell’s phytoplankton concentration and \(X_{Si-C-con}^{phy}\) is the specified (or default) constant ratio of internal silicate to carbon in the phytoplankton group being considered.
