Abstract:
The Iberian Margin, located in the North Atlantic mid-latitudes at the western edge of the European continent, is a crucial area
for climate and oceanographic reconstructions. As part of the 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 - ICW3P project, this study presents multi-proxy records from three inner-shelf sediment sequences collected from sites in the northwestern region, off the Douro River mouth (POS287-06G), west of the Tagus River mouth (POS-26B and -26G), and along the Algarve coast in front of Faro (POPEI-VC2B). The Portuguese western coast marks the northernmost boundary of the Canary Current upwelling system and experiences seasonal (May to September) wind-driven coastal upwelling. The Eastern Boundary Upwelling Systems (EBUS) are among the most productive regions in the global ocean, playing a vital role in climate regulation and supporting both local and global fisheries. Sediment records from the western coast were collected using box-core and gravity coring systems during the Poseidon Cruise PO287 in 2002, while the Algarve core POPEIVC2B was obtained with a vibro-core sampler during the POPEI Cruise in 2008. As part of a multi-proxy approach to reconstructing primary productivity and phytoplankton community variability over the past 1,000 years, we analysed diatom assemblages at site POS287_06-2G, where these microfossils are best preserved. This analysis was conducted using differential phase interference microscopy at the EMSO-Gold Optical Laboratory at IPMA.
