Abstract:
The equatorial Pacific thermocline is a critical component in determining the ocean-atmosphere interactions of the tropics. During the Pliocene warm period, the tropical thermocline was warm and/or deep and shoaled toward present day. Here we use Mg/Ca values of subsurface-dwelling Globorotalia tumida to reconstruct subsurface temperatures at Integrated Ocean Drilling Program, JOIDES Resolution, Expedition 320/321, Pacific Equatorial Age Transect, Site U1338.
