In this Accomplishment.Based renewal, the P.I. will continue the analysis of data collected on two Sea.Beam and SeaMarc II mapping projects on the Easter Microplate. Accomplishments to dte include establishment of the tectonic setting; mapping of propogating ridges and transform faults that boundt the region; spreading rates are the fastest of any ridge system yet studied; beyond a certain rate, spreading ridges are not segmented by transformed faults; the microplate originated about 4.5 Ma and has been rotating as a rigid body for at least the last 0.75 Ma. This final funding will allow the PI to complete mapping of the structural lineaments observed in the SeaMarc II data.

在这次基于成就的更新中，P.I.将继续 对两个Sea.Beam和SeaMarc II收集数据的分析 复活节微盘上的绘图项目。dte的成就 包括建立构造背景;绘制 传播的山脊和转换断层界定该地区; 扩展速度是迄今为止研究过的所有山脊系统中最快的; 超过一定的速率，扩张脊就不会被 转换断层;微板块起源于约4.5 Ma， 至少在过去的0.75百万年里一直作为刚体旋转。 这笔最终资金将使PI能够完成 在SeaMarc II数据中观察到的结构线性构造。
