This proposal requests funding for acquisition of a superconducting rock magnetometer system optimized for u-channel samples at the University of Greifswald. Such an instrument is vital for the research programmes of the applicant and will be a prerequisite to attract third party funding in future. The instrument will serve as a centrepiece in the Physical Geography department and will also be a key to derive paleomagnetic and environmental magnetic information in already funded projects such as the International Continental Scientific Drilling Program (ICDP) Project NamCore (The Nam Co Drilling Project, Tibet), which has an outstanding international visibility and is scheduled for 2023, in which the applicant of this proposal is the lead PI. Direct access to this system will spur international collaborations and will also give the University of Greifswald and Germany great visibility. The acquisition of this instrument is a natural extension of research being undertaken at the University of Greifswald, both at present and into the future, and will see heavy use by both the PI and the broader community.Using the magnetometer, both paleomagnetic and environmental magnetic investigations will be carried out. Paleomagnetic investigations will not only contribute to a better understanding of the earth's magnetic field in time and space, but paleomagnetic secular variations are frequently used in the applicant's working group to corroborate chronologies or even date sedimentary sequences. Environmental magnetic investigations complement chemical methods available in Greifswald in order to enhance the quality of paleoenvironmental reconstructions.

该提案要求提供资金，用于在格赖夫斯瓦尔德大学购置一个针对u通道样本进行优化的超导岩石磁力计系统。这种工具对申请人的研究方案至关重要，也是今后吸引第三方资金的先决条件。该仪器将作为自然地理系的核心设备，也将成为国际大陆科学钻探计划（ICDP）项目NamCore等已资助项目中获取古地磁和环境磁信息的关键（西藏纳木错钻探项目），该项目具有突出的国际知名度，计划于2023年完成，其中本建议书的申请人是主要研究者。直接进入该系统将促进国际合作，也将使格赖夫斯瓦尔德大学和德国的知名度。该仪器的购置是格赖夫斯瓦尔德大学目前和未来研究的自然延伸，将被PI和更广泛的社区大量使用。使用磁力计，将进行古地磁和环境磁力调查。古地磁调查不仅有助于更好地了解地球磁场的时间和空间，而且申请人的工作组经常使用古地磁长期变化来证实年表，甚至确定沉积序列的日期。环境磁性调查补充了格赖夫斯瓦尔德现有的化学方法，以提高古环境重建的质量。
