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.
