HIRM record for CON01-603-2

We established a mastercurve “Baikal 200” of relative paleointensity, which represents a new synthetic paleomagnetic archive for Central Eurasia. The synthetic record is composed of mean values of the six records with respect to a sliding time window of 2 ka. This compilation has been restricted to the last 200 ka in order to maintain a representative population of points (between 2 and 68). However, we present this synthetic record together with individual records and the reference paleointensity curve (Fig. 11) for the following reasons: – Each relative paleointensity record has a different resolution (e.g., sedimentation rates in CON 01-605-3 are five times higher than in VER 98-1-14). During stack procedure, smoothing of the data had the effect of lowering the resolution of the paleomagnetic information. – This stack does not provide more information on timing of the geodynamo changes since the records are tuned to ODP Site 984.

本研究构建了相对古强度（relative paleointensity）主曲线“贝加尔200（Baikal 200）”，该曲线为欧亚中部地区提供了一套全新的合成古地磁档案（synthetic paleomagnetic archive）。该合成记录以6条原始记录的平均值为基础，通过2 ka的滑动时间窗（sliding time window）计算得到。为保证数据点样本具备代表性（数据点数量介于2至68个之间），本次汇编仅涵盖过去200 ka的时段。然而，本研究同时展示该合成记录、各单条原始记录以及参考古强度曲线（图11），具体原因如下：
其一，各相对古强度记录的分辨率存在差异（例如，CON 01-605-3的沉积速率是VER 98-1-14的五倍）。在堆叠流程（stack procedure）中，对数据进行平滑处理会降低古地磁信息的分辨率。
其二，由于所有原始记录均调谐至大洋钻探计划（Ocean Drilling Program，ODP）984站位，本次堆叠无法提供更多关于地球发电机（geodynamo）活动变化时间的相关信息。
