The South Pacific Superswell: Causes and Consequences

由NSF资助的初步工作确定了一个大的 南太平洋东部与东太平洋接壤的地区 上升，并在北部的马克萨斯断裂带， 海底异常浅，未能按预期沉降 深度，由于大的热点， 人口，是由一个浅区慢剪切波 速度，并显示出地球化学异常。 在这个奖项中，麦克纳特博士将检查现有的大地水准面， 水深、年龄、地震和地球化学数据， 超井起源的理论 这项研究可能会导致 详细的野外勘探计划，以获取更多的地质和地球物理数据 为Superwell研究收集。 麦克纳特医生是一位 有能力的科学家和该项目有很高的机会， 成功

Preliminary work which was funded by NSF, identifies a large area of the South Pacific bounded on the east by the East Pacific Rise and on the north by the Marquesas Fracture Zone where the seafloor is unusually shallow, fails to subside to its expected depth, is morphologically rough due to a large hot spot population, is underlain by a shallow zone of slow shear wave velocity, and shows geochemical anomaly. In this award, Dr. McNutt will examine the existing geoid, bathymetric, age, seismic and geochemical data to test various theories of the origin of the superswell. This study may lead to a detail field program for further geologic and geophysical data collection for the superswell study. Dr. McNutt is a very capable scientist and the project has a very high chance of success.
