ngrip2010: NGRIP 20-year Average

Description

20-year averaged oxygen isotope data from the North Greenland Ice Core Project (GICC05 time scale).

Usage

ngrip2010

Format

A data.frame with 6114 observations and 4 variables:

age

integer: calendar age (years before 2000 AD), GICC05 time scale (or GICC05modelext when going beyond 60 ka b2k).

depth

numeric: depth (meters).

delta

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

MCE

numeric: maximum counting error (years).
