Bad weather hampered the planned survey work, during this time routine IGS work or equipment testing was carried our near the lea shore.

The survey objectives were hampered by bad weather. These data are archived by BGS. Technical details of the cruise are contained in BGS report WB/75/3C. BGS Geotechnical report WN/EG/76/12.
