Metadata: Predicting marine phytoplankton community size structure from empirical relationships with remotely sensed variables
Abstract:
Abundance and species composition were determined for phytoplankton in 361 water samples collected at 12 sites: five transects from 488N to 508S in the Atlantic Ocean, the Benguela upwelling, the Bergen fjord, the Irminger Sea, Long Island Sound, the North Sea, the Norwegian Sea and the Oregon upwelling.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The size composition of primary producers has a potential influence on the length of marine food chains and carbon sinking rates, thus on the proportion of primary production (PP) that is removed from the upper layers and available to higher trophic levels. While total rates of PP are widely reported, it is also necessary to account for the size composition of primary producers when developing food web models that predict consumer biomass and production. Empirical measurement of size composition over large space and time scales is not feasible, so one approach is to predict size composition from environmental variables that are measured and reported on relevant scales. Here, we describe relationships between the environment and the size composition of phytoplankton communities, using a collation of empirical measurements of size composition from sites that include polar, tropical and upwelling environments. The size composition of the phytoplankton communities can be predicted using two remotely sensed variables, chlorophyll-a concentration and sea surface temperature. Applying such relationships in combination allows prediction of the slope and location of phytoplankton size spectra and estimation of the percentage of different sized phytoplankton groups in communities.Subsamples (100 mL) were settled [Uterm?hl technique (Lund et al., 1958)] and individuals counted at the species level with an inverted microscope. Heterotrophic species were excluded from the analysis. Picoplankton was measured using flow cytometry. |
