[{"name":"hutchinson-2019-arctic-closure-1","title":"Data from a modelling study on Arctic closure as a trigger for Atlantic overturning at the Eocene-Oligocene transition","summary":"This dataset was created for a study that investigates the effect of closing the Arctic-Atlantic gateway in a coupled climate model of the Eocene-Oligocene transition (EOT), 34 million years ago. This is motivated by proxy evidence of deep waters in the Labrador Sea becoming saltier and denser in the lead-up to the EOT. We find that closure of this gateway causes a transition from North Pacific deep water formation (as seen in the Eocene) to the start-up of North Atlantic deep water. This causes a cooling of the North Pacific, and a corresponding warming of the North Atlantic. The data are presented in netcdf format and represent 50 year averages at the end of the model spinup period. Monthly and annual averages are provided.","citations":"Hutchinson, D. K., H. K.
