Mg/Ca-derived temperature estimates for ODP Site 202-1236 ...
Here we use Mg/Ca temperature estimates from subsurface and thermocline dwelling foraminifera to reconstruct the meridional Plio‐Pleistocene evolution of the Southeast Pacific thermocline, in relation to atmospheric circulation changes. Our data indicate a change in the thermocline, responding to th...
