Growth rate and Fast Repetition Rate fluorometry (FRRf) of phytoplankton

Ocean alkalinity enhancement (OAE) is a promising carbon removal method, but it may cause a significant perturbation of the ocean with trace metals such as Nickel (Ni). This study tested the effect of increasing Ni concentrations on phytoplankton growth and photosynthesis. The data were the growth rates of 11 phytoplankton species under different Ni concentrations (Master thesis project). The growth rates were calculated using daily fluorescence signal values measured by the fluorometer. Fv/Fm and SigmaPSII data were measured using Fast repetition rate fluorometry (FRRf). The growth rate and photo-physiological response of phytoplankton was analysed using generalised additive models (GAMs) and plotted in RStudio (R packages “mgcv” and “ggplot2”).
