北大西洋的雷克雅内斯海脊是海底扩张理论推导过程中的一个重要例子。1967年9月，“三叉戟”号考察船（R/V Trident）进行了一项详细的疏浚计划，配备了照相机和重力核心站，覆盖了雷克雅内斯海脊顶部（北纬60°，图1）的剖面，以寻找关于扩散机制的直接信息，并测试一种建议的解释1。许多数据已经可用2 -4。沿这条导线沿着进行的连续深度、总磁场强度和地震剖面测量将新数据与旧数据（磁力、重力和地震）联系起来。在北纬61° 25′（北纬150公里）处还有一个次要的、不完整的剖面，以及K. Horai和M.马萨诸塞州理工学院的切斯曼。
THE Reykjanes Ridge in the North Atlantic Ocean has been1 an important example in derivations of the theory of sea-floor spreading. A detailed dredging programme by the R/V Trident (September 1967) with camera and gravity core stations covered a profile across the crest of the Reykjanes Ridge (at latitude 60° N, Fig. 1) to look for direct information on the mechanism of spreading and to test one suggested explanation1. Many data were already available2–4. Continuous depth, total magnetic intensity and seismic profiling measurements along this traverse correlated the new data with the old (magnetic, gravity and seismic). There was also a secondary, incomplete profile at latitude 61° 25′ N, 150 km north, as well as heat flow measurements by K. Horai and M. Chessman of the Massachusetts Institute of Technology.
