British Geological Survey (BGS) Geophysical Survey 1978/4: SW Approaches (24/05/1978 to 12/07/1978)

Report: Armstrong, EJ. 1978. Cruise Report for Project 78/04. SW Approaches Regional Survey. (IGS Report No 92). The four legs comprising this project were designed to extendthe regional survey of the SW Approaches to the south and west of the Scilly Isles out to the Continental Shelf edge. The survey was to be carried out using shallow seismic, gravity and megnetic techniques on a skewed 7km by 12.5km grid. Due to lack of time, this program was slightly modified.报告：阿姆斯特朗（Armstrong, EJ），1978年。《78/04项目航次报告：西南近海（SW Approaches）区域勘测》（IGS第92号报告）。本项目下设四个航次段，旨在将锡利群岛（Scilly Isles）西南及南侧海域的SW Approaches区域勘测范围延伸至大陆架（Continental Shelf）边缘。原计划采用浅层地震（shallow seismic）、重力（gravity）与磁法（magnetic）勘探技术，基于倾斜7km×12.5km的测网开展本次勘测作业。后因时间不足，该勘测方案作出小幅调整。
