Short summary
A systematic investigation of the coccolithophore ecology was performed for the first time in the NW Iberian Margin to broaden our knowledge on the use of fossil coccoliths in marine sediment records to infer environmental conditions in the past. Coccolithophores proved to be significant primary producers and their abundance and distribution was favoured by warmer and nutrient–depleted waters during the upwelling regime, seasonally controlled offshore and influenced by coastal processes onshore.
