资源简介:

AGE [ka BP] is the sediment age. #0 = modern age. Atmospheric and marine radiocarbon contents and ages are values of the calibration curve published by Stuiver et al. (1998a) or Levin et al. (1997), averaged over the sediment age span. See text for the use of a reservoir age offset Delta R of 401 years. Initial D14C values are age corrected radiocarbon contents based on the sediment ages, calculated as discussed in the text. Multiple values are from fractions split before combustion.

AGE [ka BP] 代表沉积物年代。#0 代表现代年代。大气与海洋的放射性碳含量及年代数据取自Stuiver等(1998a)或Levin等(1997)发布的校正曲线(calibration curve),并在沉积物年代跨度内取平均值。关于储层年龄偏移量ΔR(取值401年)的具体使用方法,请参见正文说明。初始D14C值为基于沉积物年代计算得到的经年代校正的放射性碳含量,其计算方式详见正文论述。多组数值来源于燃烧前分馏得到的样品组分。
