Impact of climate warming in the coastal upwelling system and primary production off Portugal: a study linking classical and emergent proxies
Sobre o projeto
ICW3P aims to assess primary production variability on the Portuguese continental margin over the last millennium (Little Ice Age to present climate warming), through a high-resolution reconstruction combining biological, biogeochemical and genomic proxies.
ICW3P will reconstruct the microplankton community structure through assemblages, biogeochemical compounds and 18S metabarcoding of sedimentary ancient DNA (SedaDNA) to reconstruct primary production (PP) variations and disentangle their main drivers.
Sediment records offshore Porto, Lisbon and Faro will be studied by a multidisciplinary international team eager to contribute to UN 2030 Agenda SDG goals; to the education of young researchers; to the ocean literacy of the society at large; and to provide reliable data to advance numerical modelling of PP evolution in a warming world.
