Paul Acosta, Pacific and Atlantic Modes of Overturning in the Miocene Climatic Optimum, Submitted to Paleoceanography and Paleoclimatology, Under Review, 2025.The dataset contains the folders:output.tar : Contains all output data presented in the manuscriptctl_dirs.tar.gz : Contains control directories for running each experiment using "payu" on the National Computational Infrastructure, Australia.input.tar.gz : Contains all input folders for running the modelrestart.tar : Contains all restart folders for running the model Data are in self-describing netcdf format. In the output.tar folder, experiment names are the same as in the manuscript. In the other folders, (ctl_dirs, input and restart), the experiment names correspond to the manuscript according to the following:a15_c1 := B21_1xa15_c2 := B21_2xa15_c3 := B21_3xa15_strm_c1 := S20_1xa15_strm_c3 := S20_3xa15_strm_c1_sal := S20_1x_Sala15_strm_c3_sal := S20_3x_Sal
