AbstractGordon 0527375 This project is an investigation of the motions of the plates relative to the hotspots and of the uncertainties in those motions. The project will build on previous results and will: incorporate more hotspot tracks, construct models of seafloor isochrons for modeling hotspot tracts that have interacted with mid-ocean ridges, simultaneously invert global hotspot tracks for five key anomalies, apply the models further back in time, test the fixity of Pacific hotspots relative to Atlantic hotspots for three ages using paleomagnetic data, and test alternative global relative plate motion circuits.Broader impacts include graduate and undergraduate education and making techniques and computer programs freely available to the community, which are fairly average.

这个项目是对板块相对于热点的运动以及这些运动中的不确定性的研究。 该项目将以以往的成果为基础，并将：纳入更多热点轨迹，构建海底等时线模型，用于模拟与洋中脊相互作用的热点区域，同时反演五个关键异常的全球热点轨迹，应用更早的模型，使用古地磁数据测试三个年龄段太平洋热点相对于大西洋热点的固定性，和测试替代的全球相对板块运动电路。更广泛的影响包括研究生和本科教育，并使技术和计算机程序免费提供给社区，这是相当平均的。
