A global Pliocene-Pleistocene benthic \(\delta^{18}O\) stack.

Usage

lisiecki2005

Format

A data frame with 3 variables:

age

Calendar (calibrated) age (kilo year).

delta

Benthic \(\delta^{18}O\) (per mil).

error

Standard error (per mil).

Details

The LR04 stack spans 5.3 Myr and is an average of 57 globally distributed benthic \(\delta^{18}O\) records (which measure global ice volume and deep ocean temperature) collected from the scientific literature.
