The project will repeat a field campaign that was previously funded but could not be completed due to technical problems with the AUV Sentry. The objective is to establish a geomagnetic record for the Hawaiian Jurassic Basin by collecting high-resolution near-bottom magnetic data. Using this record, along with pre-existing data from the Japanese lineation set, the proposed work will determine whether geomagnetic field behavior was globally coherent during the Mid-Jurassic, enabling construction of a more robust geomagnetic polarity time scale for this period. Upgrades to the AUV Sentry are planned to ensure that the project does not experience the same problems that confounded the original expedition. The project will support a female early career investigator. Following on the success of outreach and education efforts on the original cruise, the investigators will recruit and mentor graduate and undergraduate student watchstanders. Data and results will be made available to scientists and the public via papers and presentations, WHOI outreach facilities, the lab groups website, and the Marine Geoscience Data System

该项目将重复先前资助的一项实地活动，但由于AUV哨兵的技术问题而无法完成。目的是通过收集高分辨率的近底磁数据，建立夏威夷侏罗纪盆地的地磁记录。利用这一记录，连同来自日本线理集的现有数据，拟议的工作将确定中侏罗世的地磁场行为是否在全球范围内一致，从而能够为这一时期构建一个更强大的地磁极性时间尺度。计划对AUV哨兵进行升级，以确保该项目不会遇到困扰最初探险的同样问题。该项目将支持一名女性早期职业研究者。在第一次巡游的推广和教育工作取得成功之后，调查人员将招募并指导研究生和本科生看守。数据和结果将通过论文和报告、WHOI外联设施、实验室小组网站和海洋地球科学数据系统向科学家和公众提供
