On 29 March 2022, the Deutsche Forschungsgemeinschaft announced the acceptance of Priority Programme 2404-- Reconstructing the Deep Dynamics of Planet Earth over Geologic Time (DeepDyn). The fundamental goal of DeepDyn is to exploit the exceptionally long paleomagnetic record, and especially changes in reversal frequency, to reconstruct the evolution of the core-mantle system. Numerical simulations indicate that the lower mantle has a manifold impact on the dynamo where the absolute value and pattern of the heat flux through the core-mantle boundary affects the field strength, field geometry and reversal rate. However, neither the long-term evolution of the lower mantle and the dynamo nor the coupling between the two are well understood, which forms the starting point of DeepDyn. Solving this puzzle will be tackled through the collaboration of five distinct scientific disciplines. (1) Paleomagnetism, to provide information about the long-term evolution of Earth’s magnetic field. (2) Dynamo models, to explore how this record can be explained, using input from material scientists and mantle dynamicists. (3) Mantle dynamics, to define the long-term evolution of the mantle and, in particular, to reconstruct the lower-mantle state based on input from material scientists and seismologists. (4) Mineral physics, to constrain the material properties relevant to the lower mantle and core. (5) Biomagnetism, to supplement the geomagnetic record by understanding the sensitivity of magnetoreceptive organisms to magnetic fields and using magnetofossils from magnetotatic bacteria as a paleofield proxy. Ensuring close integration between these five themes is a challenging task that lies at the heart of this coordination proposal. Achieving the goals of SPP2404 begins with facilitating a good communication network among the 60-70 scientists who will work individually, in small groups and in concert. Effective coordination ensures gender equality, assisting early careers scientists, and to promote the results and raise awareness of our unique endeavor within local, national, and international communities. Successful coordination of the SPP critically depends on having a Science and Administration (SA) Manager. The SA Manager will insure the cooperation and scientific exchange within and between different working groups together with the coordinator and theme leaders. The SA Manager will also coordinate the yearly colloquia, monthly seminar series and topical workshops, oversee the project budget, maintain a website, and integrate invited international experts. This proposal requests funds to hire the SA Manager and to support the activities typical of priority programs.

2022年3月29日，德意志Forschungsgemeinschaft宣布接受优先计划2404-重建地球上地球的深层动态（Deepdyn）。 Deepdyn的基本目标是利用异常长的古磁记录，尤其是逆转频率的变化，以重建核心隐身系统的演变。数值模拟表明，下地幔对发电机具有多种影响，在该发电机中，通过核心掩体边界的热通量的绝对值和模式会影响场强，场几何形状和反转速率。但是，均未熟悉下地幔和发电机的长期演变或两者之间的耦合，这构成了Deepdyn的起点。解决这个难题将通过五个不同的科学学科的合作来解决。 （1）古磁性，提供有关地球磁场长期演变的信息。 （2）发电机模型，探讨如何使用材料科学家和地幔动力学家的输入来解释该记录。 （3）地幔动力学，以根据物质科学家和地震学家的意见来定义地幔的长期演变，尤其是为了重建较低的状态。 （4）矿物质物理学，以限制与下地幔和核心相关的材料特性。 （5）生物磁场，通过了解磁场的灵敏度并将磁场的磁化物质作为古场代理来补充地磁记录。确保这五个主题之间的紧密整合是该协调建议的核心的挑战任务。实现SPP2404的目标始于支持60-70个科学家的良好沟通网络，他们将在小组和共同的情况下单独工作。有效的协调确保性别平等，协助早期职业科学家，促进结果并提高对我们在地方，国家和国际社区中独特努力的认识。 SPP的成功协调取决于拥有科学和管理（SA）经理。 SA经理将确保不同工作组和协调员和主题领导者之间和之间之间的合作与科学交流。 SA经理还将协调每年的座谈会，每月的节目系列和主题研讨会，在海外项目预算，维护网站和综合国际专家。该建议要求资金聘请SA经理并支持优先计划的典型活动。
