20-year averaged oxygen isotope data from the North Greenland Ice Core Project (GICC05 time scale).
Format
A data.frame with 4 variables:
- age
Calendar age (years before 2000 AD), GICC05 time scale (or GICC05modelext when going beyond 60 ka b2k).
- depth
(meters).
- delta
\(\delta^{18}O\) (per mil).
- MCE
Maximum counting error (years).
