Suivi de la circulation de l’eau dans l’Atlantique Nord au cours de la dernière période glaciaire à l’aide d’approches multi-proxy
Ocean circulation is a key regulator of climate that driven by both atmospheric and thermohaline processes. The Labrador Sea holds a complex mixture of water masses and plays a crucial role in North Atlantic Deep Water formation and the Atlantic Meridional Overturning Circulation, and thus for global ocean circulation. However, the mechanisms of the Labrador Sea Water formation and its interactions with upper North Atlantic Deep Water remain largely unknown. Understanding the water formation of the Labrador Sea Water and ocean circulation in the North Atlantic region in historical time by using proxy reconstruction data is crucial for benchmarking and understanding the present and future variations using model simulations. The purpose of this proposal is to provide information on the evolution of the North Atlantic intermediate water formation and the impact of changes on ocean circulation in the Labrador Sea during several cold periods including the Last Glacial Maximum, understanding of North Atlantic water inflow, the Labrador Sea deep water ventilation conditions and formation respond to the fundamentally different glacial cold events. By combining benthic foraminiferal morphology and geochemistry data, and other existing proxies, this project will discover the link between shell morphology and multiple stresses, and quantitatively evaluate the impact of changes in the ocean circulation on marine ecosystems. The project aims to apply a multiproxy approach including the application of foraminiferal morphology and geochemistry to reconstruct the seawater conditions. I will generate new high-resolution records of changes in subsurface to deep-water formation in the Labrador Sea region to evaluate the impact of changes in ocean circulation and to significantly improve the application of this multiproxy approach. Results from this project will also increase the data window of oceanic circulation for climate model validation.
