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”).

- Statement
- Phytoplankton cultures were kept in tubes and grown at 17°C. The light was provided on a 14-to-10-hour daily cycle (cool white fluorescence light) where light intensities were 58 μmol photons m-2 s-1 (14 hours) and 23 μmol photons m-2 s-1 (10 hours). The fluorescence of these cultures was measured daily using a fluorometer and values during the exponential growth phase were ln-transferred for growth rate calculation. Fv/Fm and SigmaPSII data were measured using Fast repetition rate fluorometry (FRRf). The growth rate and photo-physiological response of phytoplankton were analysed using generalised additive models (GAMs) and plotted in RStudio (R packages “mgcv” and “ggplot2”).
