Size fractionation, chemotaxonomic groups and bio-optical properties of phytoplankton along a transect from the Mediterranean Sea to the SW Atlantic Ocean

Abstract: The relationships between the structure of the phytoplankton community and the bio-optical properties of surface waters were studied during the TransPEGASO cruise along a transect across the Atlantic Ocean that covered seven biogeographical provinces, from the Alborán Sea (SW Mediterranean) to the Patagonian Shelf. We characterized the composition of the phytoplankton community by means of high-performance liquid chromatography and CHEMTAX pigment analyses applied to whole water and two filtration size classes… Show more

“…For the gyre regions SATL, NATR, NASE, and WTRA TChla, PG Chla and PG Chla contributions to TChla from our data agree well to the other studies, except that in WTRA, SATL, and NASE the contribution by cyanobacteria in our study is higher (∼30%) than in Taylor et al (2011) and Nunes et al (2019), ∼15 and ∼10%, respectively). Within NASE in Taylor et al (2011) and Nunes et al (2019) Prochlorococcus contribute more (∼40%), while in our study the contribution of Prochlorococcus is significantly less (∼25%). It may be due to that relating the zeaxanthin concentration just to monovinyl-Chla and chlorophyllide a concentrations to obtain cyanobacteria Chla in our method is not sufficiently accounting for the contribution of Prochlorococcus to zeaxanthin.…”

“…Results for the CNRY region differ the most among the studies: While Nunes et al (2019) observe oligotrophic conditions with very low surface TChla (only ∼25% of our values), values in Barlow et al (2002) and Taylor et al (2011) are much higher (3.2 ± 1.7 mg/m 3 and 1.5-2 mg/m 3 , respectively). In Nunes et al (2019) the phytoplankton composition in CNRY is similar to NASE, except that Prochlorococcus decrease to ∼18% and diatoms increase to ∼15%. For Taylor et al (2011), the composition is similar to what we obtained for NECS, with diatoms dominating by ∼60% the biomass, followed by haptophytes and cyanobacteria (here grouped as Synechococcus) with about 10-15%.…”
