The delta18O values of planktonic foraminifera increased in the Caribbean by about 0.5‰ relative to the equatorial East Pacific values between 4.6 and 4.2 Ma as a consequence of the closure of the Central American Gateway (CAG). This increase in delta18O can be interpreted either as an increase in C...
