Introduction The auxiliary material provides additional analyses of ECBILT-CLIO model output, which are presented to assess the role of wind-stress changes on the Pacific tropical thermocline in response to the closure of the Central American Seaway. 1. 2008pa001645-txts01.pdf Assessment of the influence of wind-stress changes on Pacific thermocline depth.
