Marine data for calibration of 14C age
Marine20.Rd
As 14C years is not equal to calendar years because atmospheric 14C concentration varies through time. Hence, data in marine_CalC14 allows a calibration for hypothetical "global" marine reservoir.
Usage
data("Marine20")
Format
A data frame with 3 variables.
CAL.BP
a numeric vector correpondig to calendar years befor present
X14C.age
a numeric vector correponding to 14C age
Error
a numeric vector correponding to error arround 14C age measurement
