1977年7月，利用RRS“发现号”上的远程（30 km）双面声纳（格洛丽亚Mk II）和安装在船体上的中程（2.5 km）声纳，通过侧扫声纳测量，研究了北纬58”至61”之间雷克雅内斯海脊中部100 km的增生和构造过程（图1）。在中部30公里处制作了一系列窄波束回声测深剖面。同时制作了地震、磁力和重力剖面图。本文是对1977年9月在达勒姆举行的IASPEI/IAVCEI会议上报告的这次航行的主要发现的初步叙述，以及对数据的一些初步解释。
The accretion and tectonic processes of the central 100 km of the Reykjanes Ridge between 58” and 61” N (Fig. 1) were studied in July 1977 by side-scan sonar survey using the long range (30 km) double sided sonar (GLORIA Mk II) and the hull mounted medium range (2.5 km) sonar on RRS “Discovery”. A series of narrow beam echo-sounding sections was made across the central 30 km. Seismic, magnetic and gravity profiles were made simultaneously. This paper is a preliminary account of the principle findings of the cruise as reported in September, 1977, at the IASPEI/IAVCEI meeting in Durham, together with some initial interpretation of the data.
