Effect of phytoplankton size classes on bio-optical properties of phytoplankton...
Brito, Ana C.; Sá, Carolina; Brotas, Vanda; Brewin, Robert J.W.; Silva, Teresa; Vitorino, João; Platt, Trevor; Sathyendranath, ShubhaChlorophyll-a satellite products are routinely used in oceanography, providing a synoptic and global view of phytoplankton abundance. However, these products lack information on the community structure of the phytoplankton, which is crucial for ecological modelling and ecosystem studies. To assess the usefulness of existing methods to differentiate phytoplankton functional types (PFT) or phytoplankton size clas...
Influence of light in the mixed-layer on the parameters of a three-component mo...
Brewin, Robert J.W.; Sathyendranath, Shubha; Jackson, Thomas; Barlow, Ray; Brotas, Vanda; Airs, Ruth; Lamont, TarronPhytoplankton size structure is an important indicator of the state of the pelagic ecosystem. Stimulated by the paucity of in situ observations on size structure, and by the sampling advantages of autonomous remote platforms, new efforts are being made to infer the size-structure of the phytoplankton from oceanographic variables that may be measured at high temporal and spatial resolution, such as total chlorop...
Deriving phytoplankton size classes from satellite data: validation along a tro...
Brotas, Vanda; Brewin, Robert J.W.; Sá, Carolina; Brito, Ana C.; Silva, Alexandra; Mendes, Carlos Rafael; Diniz, Tânia; Kaufmann, Manfred; Tarran, GlenIn recent years, the global distribution of phytoplankton functional types (PFT) and phytoplankton size classes (PSC) has been determined by remote sensing. Many of these methods rely on interpretation of phytoplankton size or type from pigment data, but independent validation has been difficult due to lack of appropriate in situ data on cell size. This work uses in situ data (photosynthetic pigments concentrat...
