Description
Summary:Here we publish simulated early-middle Eocene annual mean ocean temperature, salinity, density, mixed layer depth and current velocities (at the depth of ~1500 m) with different gateways configurations in the North Atlantic region. The details of original paleogeography, compiled by GETECH, are provided in Vahlenkamp et al. [2018, doi:10.1016/j.epsl.2017.12.016]. The CO2 level is set to 840 ppm, while the obliquity to a minimum value. All data are averaged over the period of 100 years. All simulations were run with COSMOS (ECHAM5/MPIOM/OASIS3). The atmosphere component ECHAM5 was run in the resolution of T31/L19, while the ocean model MPIOM has a formal resolution of ~3.0°x1.8°. OASIS3 is a coupler between the atmosphere and ocean components.The gateway alterations with respect to original paleogeography include an opening of the Arctic and Tethyan Seaways, as well as changing the depth of the Greenland-Scotland Ridge to 50 m and 200 m [Vahlenkamp et al., 2018, doi:10.1016/j.epsl.2018.06.031]. We publish ... : In each NetCDF file there are variables:THO - ocean temperature,SAO - ocean salinity,UKO - zonal ocean currents (shown only at the depth of 1.5 km),VKE - meridional ocean currents (shown only at the depth of 1.5 km),rhopoto - ocean density.In the file cntrl840 there are also variables:THO_DJF and THO_JJA: boreal ocean winter and summer temperatures,tsurf, tsurf_DJF and tsurf_JJA: surface air temperature (annual, boreal winter and summer).All details are explained in the manuscript. ...
