Dr. Gavin Tilstone is an oceanographer in the field of NERC sensor scientific officer and Bio-optical Oceanographer in Plymouth Marine Laboratory, UK. His main research interestes focus on the optics, photosynthesis, phytoplankton, primary production, remote sensing.


Coastal waters are optically more complex, and the use of chlorophyll a (chi a) as a first-order predictor of primary production may lead to substantial errors due to significant quantities of coloured dissolved organic matter (CDOM) and total suspended material (TSM) within the first optical depth. In the second report, I will represent a model that use of phytoplankton absorption as a proxy to estimate primary production in the coastal waters of the North Sea and Western English Channel for both total, micro- and nano+pico-phytoplankton production. The model had >250% accuracy of similar chl a based production model.
