Sampling

Method steps

1. Phytoplankton abundance at several depth strata collected in a fixed oceanograpgic station in the Northwest Iberian shelf.

   Monthly sampling at sea with regional Research Vessel. Sample acquisition using Niskin bottles with a rossette sampler equiped with CTD probe and other automatic sensors (e.g. in vivo fluorescence). Fixation and preservation of samples with Lugol. Analysis at the laboratory under the inverted microscope following Uthermol protocols.

   Scientific names according to World Register of Marine Science (WoRMS). Periodical intercalibration among expert phytoplankton taxonomists.
