Submission summary

The hydrological cycle plays an important role in the Earth´s climate and is vital for Human populations. The spatial pattern of climatological mean sea surface salinity (SSS) is highly correlated with the long-term mean Evaporation-Precipitation spatial pattern and therefore constitute a particularly sensitive marker of water cycle. In this project, we propose to reconstruct past low latitude hydrological changes by constraining past salinity changes using innovative approaches. The reconstruction of past SSS remains a challenge in paleoclimatology. We propose a combination of different approach based on bio/geochemical analyses in marine sediment cores and integration with numerical models. Results will serve to evaluate numerical climate models used to predict future climate change in the low latitude hydroclimate and its impact.
