In 2023, I started a FCT young researcher contract to develop the project CHUVA, Land-Sea dynamics in East Asia: Deciphering the impact of high-latitude versus tropical forcing, aiming at providing new insights on the hydrological cycle in East Asia (#grant: 2022.03976.CEECIND). One of the main goal of CHUVA is to reconstruct vegetation-based hydroclimate variability, as well as simultaneous sea-surface changes in the East Sea across the Plio-Pleistocene (~the last 5 Ma). This land-sea reconstruction will be crucial to assess potential regional oceanic feedbacks on the frequency and amplitude of monsoonal rainfall changes. The project is mostly based on the examination of microfossils from two neighbouring deep-sea sequences collected in the East Sea, namely IODP Site U1425 and core ES14-GC01. The originality of the project relies on an innovative palynological approach, combining systematically a jointed-analysis of terrestrial (i.e. pollen grains) and marine (i.e. dinocysts) palynomorphs, which is the rare way to explore through the same analysis the interactions of the land atmosphere-ocean systems without chronological ambiguities.
