Dome C age scale EDC2 for ice core EDC@en

EDC2 timescale, adopted by SC December 2003. EDC2 was recommended for all EPICA papers below 800 m until EDC3 was adopted. Matches EDC1 (doi:10.1594/PANGAEA.198748) at 800 m in ice scale. EDC1 was recommended above 800 m. However, the new timescale EDC3 (doi:10.1594/PANGAEA.671367) has been recommended since mid 2007, and supersedes both EDC1 and EDC2 which are now only shown for reference, to enable those using older papers to understand what was used.EDC2时间标尺于2003年12月由SC通过。在EDC3被采用之前，EDC2被推荐用于所有800米深度以下的EPICA（欧洲南极冰芯钻探计划，European Project for Ice Coring in Antarctica）研究论文。该标尺在冰芯深度800米处与EDC1（doi:10.1594/PANGAEA.198748）标尺匹配。800米深度以上的冰芯则推荐使用EDC1标尺。不过，自2007年中期起，新的时间标尺EDC3（doi:10.1594/PANGAEA.671367）被正式推荐，并取代了EDC1与EDC2；目前仅将后两者作为参考资料展示，以便使用过往研究论文的用户明晰当时所采用的标尺。
