#' The Marine20 calibration curve
#'
#' A [tibble][tibble::tibble()] containing the Marine20 marine radiocarbon calibration curve.
#'
#' `marine20` is a [tibble::tbl_df-class] object with the following fields:
#'
#' * **CAL BP** --- The calibrated year before present
#' * **14C age** --- The un-calibrated 14C age of the sample, in years before present
#' * **Error** --- The measurement error of the 14C age, in years before present
#' * **Delta 14C** --- The normalized delta 14C (Δ14C) measurement for the sample, in per mil (‰)
#' * **Sigma** --- The standard deviation (σ) of the Δ14C measurement, in per mil (‰)
