FAMOSO (Fate of the northwestern Mediterranean open sea spring bloom), an investigation project on oceanic plankton and biogeochemical dynamics north of the IDEADOS area. During The 3 cruises sampled different oceanographic conditions, starting with early stages of the late winter-early spring bloom, followed by the late stage of the bloom, and finally summer stratification .Starting with the late winter-early spring phytoplankton bloom in FAMOSO-1: (14 to 22 March) the post-bloom in FAMOSO-2 ( 30 April to 13 May) and the late stratification in FAMOSO-3 ( 17 to 19 September). During these cruises, conductivity-temperature-depth (CTD) profiles were conducted with a SBE911plus probe (SeaBird Electronics) attached to a rosette equipped with Niskin bottles. Samples were collected from 19 CTD casts for the determination of dissolved inorganic nitrogen and phosphate, as well as picoplankton abundance and cell properties. Wind speed data were collected by the onboard meteorological station
