A new downhole magnetic susceptibility (MS) tool will provide logging data to enhance paleoclimate and sedimentological studies under IODP and will complement the existing multisensor gamma ray tool (MGT). The project will design a MS tool that has better resolution (10 cm as opposed to 1 m) than the tool previously available for some legs of the ODP program. The resulting data will prove critical for the intercorrelation of cores from multiple holes and the integration of cores and logs from single holes. The tool will be built from off-the-shelf sensor fit with the appropriate pressure housing and data acquisition/transmission system, and the proponents intend to comply with third-party downhole tool guidelines articulated by the IODP advisory structure. The MS tool could find potential application not only in the deep-sea environment, but also in lacustrine and continental settings. It is expected that the MS tool will eventually be routinely run as part of nearly every IODP program on the non-riser vessel. Field tests on the new tool are scheduled for late 2005 and 2006.

一种新的井下磁敏感性（MS）工具将提供记录数据，以增强IODP下的古气候和沉积学研究，并将补充现有的多传感器伽马射线工具（MGT）。 该项目将设计一个具有更好分辨率（10厘米而不是1 m）的MS工具，而不是以前可用于ODP程序的某些腿的工具。 最终的数据将证明对于来自多个孔的核心以及岩心和对数的集成至关重要。该工具将由现成的传感器构建，并具有适当的压力外壳和数据采集/传输系统，并且支持者打算遵守IODP咨询结构所阐明的第三方井下工具指南。 MS工具不仅可以在深海环境中找到潜在的应用程序，还可以在湖间和大陆设置中找到潜在的应用程序。 可以预期，MS工具最终将通常作为非式船只船上的所有IODP程序的一部分进行。 新工具上的现场测试计划于2005年末和2006年进行。
