Cruise period1973-08-22 — 1973-09-02
StatusCompleted
PurposeTrials
ObjectivesThe purpose of the project was threefold:
1. To assess the radiometric eel as a viable piece of offshore research equipment.
2. To ascertain the compatability of the radiometric eel with other routine geophysical equipment, namely sparker, pinger, magnetometer, gravimeter and transit sonar.
3. To survey an area where good geological control already existed (from previous work by CSU II and MGU), with the view to a geological assessment of the radiometric results.
