This work will integrate magnetic anomaly, geochemical, and paleointensity data to address a variety of ridge crest processes. The working hypothesis is that coherent features in the magnetic anomaly/inversion records, especially within the Brunhes including the Central Anomaly Magnetic High, are most probably due to geomagnetic intensity variations. A magnetic study of submarine and rock core samples from the East Pacific Rise near 9 degrees north will be conducted to corroborate the geomagnetic origin of critial features in the anomaly patters with glass paleointensities, establish if there is indeed a link between the glass paleointensities and basalt magnetizations, and explore the utility of the glass paleointensities as a dating tool.

这项工作将整合磁异常，地球化学和古强度数据，以解决各种脊顶过程。 工作的假设是，磁异常/反演记录中的相干特征，特别是在Brunhes包括中央异常磁高，最有可能是由于地磁强度变化。 将对北纬9度附近东太平洋海隆的海底和岩芯样品进行磁性研究，以证实玻璃古强度异常模式中关键特征的地磁起源，确定玻璃古强度和玄武岩磁化之间是否确实存在联系，并探索玻璃古强度作为测年工具的实用性。
