Table 1 Fit coefficients (k₁, k₂, k₃, k₄, k₅, k₆), R², p-values, F-values and degrees of freedom obtained from fit equation (2) for calcification (pg C cell⁻¹ d⁻¹), photosynthetic carbon fixation (pg C cell⁻¹ d⁻¹) and growth rate (d⁻¹) fits to all data. Note that for calcification and photosynthetic carbon fixation rates the unit of k₁ is pg C cell⁻¹ day⁻¹ and for growth rates day⁻¹.
