已构建并批准了新的放射性碳校准曲线INTCAL04和MARINAL04，以取代Intcal98的陆地和海洋成分。新的校准数据集从0-26 Cal Kyr BP（在现场之前为0Cal。BP= AD 1950）额外扩展了2000年，并提供了比Intcal98更高的分辨率，更高的精度和更详细的结构。对于Marine04曲线，用盒子扩散模型转换为海洋混合层年龄，覆盖0-10.5呼叫Kyr BR超过10.5 cal Kyr BP，高分辨率海洋数据可从0-10.5 Call Kyr BR覆盖，从有孔虫中的有孔虫中的沉积物和U/THETED珊瑚。使用特定地点的C-14储层年龄信息对海洋记录进行校正说明日历年龄和C-14年龄的不确定性，以计算潜在的校准曲线（Buck和Blackwell，此问题）。这里讨论了来自表面混合层的海洋样品的海洋数据集和校准曲线（Marine04）。 Reimer等人在同伴论文中详细介绍了树环数据集，不确定性来源和区域偏移。 （这个问题）。
New radiocarbon calibration curves, IntCal04 and Marine04, have been constructed and internationally ratified to replace the terrestrial and marine components of IntCal98. The new calibration data sets extend an additional 2000 yr, from 0-26 cal kyr BP (Before Present, 0 cal. BP = AD 1950), and provide much higher resolution, greater precision, and more detailed structure than IntCal98. For the Marine04 curve, dendrochronologically-dated tree-ring samples, converted with a box diffusion model to marine mixed-layer ages, cover the period from 0-10.5 call kyr BR Beyond 10.5 cal kyr BP, high-resolution marine data become available from foraminifera in varved sediments and U/Th-dated corals. The marine records are corrected with site-specific C-14 reservoir age information to provide a single global marine mixed-layer calibration from 10.5-26.0 cal kyr BR A substantial enhancement relative to IntCal98 is the introduction of a random walk model, which takes into account the uncertainty in both the calendar age and the C-14 age to calculate the underlying calibration curve (Buck and Blackwell, this issue). The marine data sets and calibration curve for marine samples from the surface mixed layer (Marine04) are discussed here. The tree-ring data sets, sources of uncertainty, and regional offsets are presented in detail in a companion paper by Reimer et al. (this issue).
