FastOcean APD Profiling System for in situ estimation of Gross Primary Productivity (GPP)

FastOcean APD Profiling System for in situ estimation of Gross Primary Productivity (GPP)

Fast Repetition Rate (FRR) fluorometry provides a non-intrusive and non-destructive method for probing photosynthesis by phytoplankton. The two FRR fluorometers within the FastOcean Ambient Plus Dark(APD) profiling system generate the data required to estimate the electron flux through all photosystem II (PSII) reaction centres per unit volume of sea water, on wide spatial and temporal scales. Given that Gross Primary Productivity by phytoplankton (GPP) is generally the main sink for PSII electron flux, these data can be used to estimate GPP. When the APD system is not being used for profiling, one or both of the FastOcean sensors can quickly be removed from the frame and coupled with one or two Act2 laboratory systems (see separate brochure).

The combination of FastOcean and Act2 allows fully automated fluorescence light curves (FLCs) to be run on discrete samples collected in the field or phytoplankton cultures.
