A compilation of global bio-optical in situ data for ocean-colour satellite app...
Valente, André; Sathyendranath, Shubha; Brotas, Vanda; Groom, Steve; Grant, Michael; Taberner, Malcolm; Antoine, David; Arnone, RobertA global compilation of in situ data is useful to evaluate the quality of ocean-colour satellite data records. Here we describe the data compiled for the validation of the ocean-colour products from the ESA Ocean Colour Climate Change Initiative (OC-CCI). The data were acquired from several sources (including, inter alia, MOBY, BOUSSOLE, AERONET-OC, SeaBASS, NOMAD, MERMAID, AMT, ICES, HOT and GeP&CO) and span t...
Delineation of ocean surface provinces over a complex marine domain (off SW Ibe...
Krug, Lilian; Platt, Trevor; Barbosa, Ana B.incorporating its dynamic nature. The area off Southwest Iberian Peninsula (SWIP), located between temperate and subtropical waters, includes oceanic and coastal domains affected by atmospheric and ocean circulation patterns, as well as coastal processes. The objectives of this study were to delineate a dynamic abiotic-based partition of the heterogeneous surface SWIP area into environmental provinces (EPs), ev...
Patterns and drivers of phytoplankton phenology off SW Iberia: a phenoregion ba...
Krug, Lilian; Platt, Trevor; Sathyendranath, Shubha; Barbosa, Ana B.Phytoplankton patterns, tightly linked to the dynamics of the ocean surface layer and its atmospheric forcing, have major impacts on ecosystem functioning and are valuable indicators of its response to environmental variability and change. Phytoplankton phenology and its underlying drivers are spatially variable, and the study of its patterns, particularly over heterogeneous regions, benefits from a delineation...
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...
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...
Connections between upwelling patterns and phytoplankton variability under diff...
Krug, Lilian; Silvano, Kathleen M.; Barbosa, Ana B.; Domingues, Rita B.; Galvão, Helena M.; Luis, Joaquim; Platt, Trevor; Relvas, PauloThe region off southwestern Iberia (NE Atlantic) encompasses a wide variety of oceanographic regimes, including differently (geographic) oriented coastal areas impacted by upwelling, riverine inputs and submarine groundwater discharge, submarine canyons and seamounts, and open ocean waters, thereby potentially promoting zone-specific phytoplankton dynamics. Overall, this heterogeneous region is classified as be...
