Report: Armstrong, EJ. 1979. Cruise Report for Project 79/02 and Project 79/16. (IGS Report No 100).
Project 79/16 was run with the aim of providing shallow seismic control over a number of sites due to be drilled later in 1979. The sparker and deep tow boomer gave good resolution and penetration down to 100msec and 25msec respectively.
