Objectives | To complete a 15km grid between latitudes 56 and 57N from the Scottish coast to the median line, covering the Tay Forth, Marr Bank, Devil's Hole and Fisher sheets of the IGS 1:250 000 amp series. Secondary objectives were to survey along the track of a digital sparker line in the Fisher/Forties area which had been shot for IGS earlier in the year by Gardline Surveys Ltd to clarify earlier geophysical work in the Bosies Bank/Caithness area.
Lines 1-11 totalling 1114km were surveyed. The gravity meter operated well providing good results. Limited data aquired on this leg. |
