IODP Expedition 359 Magnetic remanence (SRM-longcore)

Magnetic remanence was measured on section halves (and rarely on whole-round sections) using a 2G Enterprises 760R cryogenic magnetometer, first as natural remanent magnetization (NRM) and then after demagnetization steps were performed on the samples by alternating field (AF) demagnetizer coils mounted in-line within the instrument.采用2G Enterprises公司760R型低温磁力仪对岩心半段（极少数情况下使用整段岩心）开展剩余磁化强度（Magnetic remanence）测量：首先对样品进行天然剩磁（natural remanent magnetization, NRM）测定，随后借助仪器内置同轴安装的交变场（alternating field, AF）退磁线圈完成样品退磁步骤后，再次开展剩余磁化强度测量。
