Short summary
The Gulf Stream plays a crucial role in the ocean stability and climate regulation of the Northern Hemisphere. By analysing the fossil microorganisms that lived in the water column and the ocean floor, as well as reconstructing the ancient ocean's biogeochemistry, we were able to trace longitudinal shifts in the Gulf Stream during the late Eocene (36 Ma). Our results provide insight into the Gulf Stream's behaviour and the NW Atlantic's palaeoceanography during the Late Eocene (ca. 36 Ma).
