Over the last year, Chelsea Technologies Group (CTG) has seen a number of publications appear regarding the use of the FastOcean Fast Repetition Rate fluorometer (FRRf) in the field. The FRRf is a great tool for measuring primary productivity and assessing the health of phytoplankton communities. The published papers (see below) demonstrate a wide range of uses for the instrument. These include investigating phytoplankton physiology in the Southern Ocean with regard to iron availability, comparing the effect of ocean acidification and irradiance on photophysiology in different phytoplankton groups and investigating the effect of silver nanoparticle toxicity in diatoms.
One paper has been dedicated to comparing methods of primary production monitoring and highlights the relative usefulness of FRRf with regards to spatial resolution and automation (Kromkamp et al. 2017).
These papers highlight the benefits of using FastOcean as a non-invasive method for measuring in situ primary production at a high spatial resolution and the instrument’s continued relevance in understanding global phytoplankton communities and their response to a changing environment.
