Coordination Funds

2022年3月29日，德国财政部宣布接受优先计划2404--重建地球地质时期的深部动力学(DeepDyn)。DeepDyn的基本目标是利用超长的古地磁记录，特别是反转频率的变化，重建核幔系统的演化。数值模拟表明，下地幔对发电机的影响是多方面的，其中通过核幔边界的热通量的绝对值和模式影响场强、场几何形状和反转率。然而，无论是下地幔和发电机的长期演化，还是两者之间的耦合，都没有得到很好的理解，这构成了DeepDyn的起点。解决这一难题将通过五个不同的科学学科的合作来解决。(1)古地磁，提供有关地球磁场长期演变的信息。(2)发电机模型，利用材料科学家和地幔动力学家的意见，探索如何解释这一记录。(3)地幔动力学，以确定地幔的长期演化，特别是根据材料科学家和地震学家的输入重建下地幔状态。(4)矿物物理，以约束与下地幔和核相关的材料性质。(5)生物磁学，通过了解感磁生物对磁场的敏感性和利用来自磁性细菌的磁化石作为古磁场的替代物来补充地磁记录。确保这五个主题之间的紧密结合是一项具有挑战性的任务，它是这项协调提案的核心。实现SPP2404的目标首先是促进60-70名科学家之间良好的沟通网络，这些科学家将单独、以小组形式和协同工作。有效的协调确保性别平等，帮助早期职业科学家，并促进成果并提高人们对我们在地方、国家和国际社会中独特努力的认识。SPP的成功协调至关重要地依赖于拥有一名科学和行政(SA)经理。SA经理将与协调员和主题负责人一起确保不同工作组内部和之间的合作和科学交流。SA经理还将协调年度研讨会、每月研讨会系列和专题研讨会，监督项目预算，维护网站，并整合受邀的国际专家。该提案要求提供资金来聘用SA经理，并支持优先计划的典型活动。

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.
