ObjectivesM.V. Hawthorn was chartered to act as shooting ship for the project. A total of 68.5 short (2,000lbs) tons fo Geophex explosive was to be carried and 236 shots of 300, 600 or 1200 lbs fired by slow burning fuse wherever possible at the optimum depth for generation of seismic energy. The area of operations extended from The Minch to Iceland. The shooting was planned to take place between July 10th and July 28th. The ship was required to transmit information on the shooting operation to two ships engaged in recording the seismic arrivals at sea and to 20 temporary recording staitons on land in the U.K. (8 stations), the Faeroe Islands (6 stations), and Iceland (15 stations). The time of the shots was to be determined to an accuracy of better than 1/20th sec, the position to be better than 1/2n.m. and the water depth at each set to a few metres.
