| contents | The Iberian Margin, located in the mid-latitude North Atlantic at the western edge of the European continent, is a key region for climate and oceanographic research. The Portuguese western coast marks the northernmost boundary of the Canary Current upwelling system, experiencing seasonal wind-driven coastal upwelling from May to September. Eastern Boundary Upwelling Systems (EBUS) are among the most productive regions in the global ocean. They play a vital role in climate regulation and support both local and global fisheries. As part of the ICW3P project (PTDC/CTA-CLI/2884/2021) 'Impact of climate warming in the coastal upwelling system and primary production off Portugal: a study linking classical and emerging proxies', this study presents multi-proxy records from three inner-shelf sediment sequences. The project aimed to evaluate different nutrient sources and paleoceanographic features of the Iberian Margin and to reconstruct primary productivity and phytoplankton community variability over the past 1,000 years. This dataset presents stable oxygen (d18O) and carbon (d13C) isotope values from a sediment record collected in front of Faro (POPEI-VC2B), along the Algarve coast, obtained with a vibro-core sampler during the POPEI Cruise in 2008. Isotopes were measured in foraminiferal calcite from planktonic (G. bulloides and G. inflata) and benthic (Uvigerina sp.) species, at the Marum Stable Isotope Laboratory (University of Bremen) in 2025, by gas isotope ratio mass spectrometer, Finnigan MAT 251 GC-IRMS system, coupled to a Kiel I automated carbonate preparation device. |
