0452132AbstractHeyAbstractThe Reykjanes Ridge is one of the most striking parts of the mid-ocean ridge system on global maps of gravity and bathymetry because of the V-shaped diachronos ridges pointing away from Iceland. It shows the strongest influence of a hotspot (Iceland) of any mid-ocean ridge and is the type example of an obliquely spreading ridge. This project will test two hypotheses for the origin of the V-shaped ridges; pulsing of the Iceland plume versus ridge jumps. The goal is to provide a seamless history of the plate boundary geometry both at sea and on land during the past 18 Ma. Marine geophysical data will be collected in the area from the Iceland margin to the northern boundary of the existing data at 62 degrees north.The study involves the training of a graduate student and Icelandic scientists will participate in the expedition and receive training in various aspects of data gathering. They will also provide a critical link to the land data.

雷克雅未克海脊是全球重力和测深图上洋中脊系统最引人注目的部分之一，因为V形的穿时脊指向远离冰岛。它显示了任何洋中脊的热点（冰岛）的最强影响，是斜向扩张脊的典型例子。 该项目将测试V形脊起源的两个假设;冰岛羽流脉冲与脊跳跃。 我们的目标是提供一个无缝的历史板块边界的几何形状在海上和陆地在过去的18马。 将在从冰岛边缘到北纬62度现有数据的北方边界的地区收集海洋地球物理数据。研究涉及培训一名研究生，冰岛科学家将参加考察，并接受数据收集各方面的培训。它们还将提供与土地数据的重要联系。
