Potential Role of Mid‐Latitude Seaway on Early Paleogene Atlantic Overturning Circulation
Abstract The role of the mid‐latitude seaway between the proto‐Paratethys and the North Sea on the early Paleogene ocean circulation is examined with a state‐of‐art earth system model. The early Eocene simulations here demonstrate that the open mid‐latitude seaway captures most relatively fresh surf...
