9814129 Merrill Variations in the geomagnetic secular variation of Earth's magnetic field come from dipole and nondipole sources. There is little agreement as to the origins of these sources. The PI plans to carry out detailed analyses of paleomagnetic secular variation data and magnetic field reversal data to help resolve the differences in viewpoints expressed by different scientists. A more coherent picture of the nature of the changes in Earth's magnetic field with time and their relationship to geodynamo theory will be developed.

9814129梅里尔地磁场长期变化的变化来自偶极子和非偶极子源。 关于这些来源的起源，人们意见不一。 PI计划对古地磁长期变化数据和磁场反转数据进行详细分析，以帮助解决不同科学家表达的观点差异。 将对地球磁场随时间变化的性质及其与地球发电机理论的关系提出一个更加连贯的看法。
