A Regional Study: The Origin of the Hawaiian Hotspot Trail

该奖项将支持对遥远西北太平洋地质史的海洋地质和地球物理研究。实地工作将包括收集阿留申海沟和堪察加海沟交汇处以及皇帝海山链北端附近地区的地震反射、重磁数据。研究项目的主要目的是：1)描述皇帝热点轨迹的早期历史和岩石圈对火山作用的响应；2)重建该部分太平洋的板块构造史；3)确定该地区中生代沉积物的分布。了解演化和沉积物分布对于确定海洋钻探的候选地点至关重要。此外，伍兹霍尔海洋研究所的科学家将研究岩心沉积物，以确定该地区的古海洋学历史。首席调查员非常有资格进行这项研究。现场工作将在斯克里普斯研究所运营的华盛顿号房车的35天邮轮上完成。

This award will support a marine geological and geophysical study of the geological history of the far northwestern Pacific. Field work will include the collection of seismic reflection, gravity and magnetic data from the area near the confluence of the Aleutian and Kamchatka Trenches and the northern end of the Emperor Seamount chain. The main objectives of the research project are to: 1) describe the early history of the Emperor hot- spot trail and the lithospheric response to volcanism; 2) reconstruct the plate tectonic history of this part of the Pacific; and 3) to determine the distribution of Mesozoic sediments in the region. Understanding the evolution and sediment distribution will be critical in identifying candidate sites for ocean drilling. Additionally, scientists from Woods Hole Oceanographic Institution will examine cored sediments to determine the paleoceanographic history of the area. The principal investigator is highly qualified to undertake this study. Field work will be done on a 35 day cruise of the R.V. Washington operated by Scripps Institution.
