ObjectivesThe vessel sailed from Dundee and conducted two days of Huntec boomer trials. Gravity transit lines 23-25 totalling 447km were completed en route from the boomer trials area. Lines 26-36 totalling 1729km were completed in the main survey area. A watergun was used in preference to the air gun due to the absence of a bubble pulse. Gravity results were good and the accuracy was enhanced by the high quality navigatation resulting in good definition of the Eotvos curves.

During this leg the CAMAC minilogger underwent its first sea trials. Gravity, magnetic and depth data were logged successfully but only for a few hours at a time.
