9632858 Gordon The PIs propose an interdisciplinary study to improve paleomagnetic estimates of polar motion and their uncertainties, and to derive better models of the effects of geophysical processes on long-term rotational dynamics. The PIs will combine observational paleomagnetic data used to constrain polar wandering curves, and geodynamic modeling focused on discriminating among alternative geophysical processes that may have affected true polar wander in the past 25 Myr. ***

9632858戈登的PI提出了一个跨学科的研究，以提高古地磁的极地运动及其不确定性的估计，并得出更好的地球物理过程对长期旋转动力学的影响模型。 PI将结合联合收割机观测古地磁数据，用于约束极移曲线，地球动力学建模侧重于区分可能影响过去2500万年真实极移的替代地球物理过程。 ***
