Cruise summary report
|Ship name (ship code)||RRS Shackleton (74SF)|
|Cruise identifier||S1/74 Legs 3,4|
|Cruise period||1974-06-11 — 1974-06-29|
|Port of departure||Famagusta, Cyprus|
|Port of return||Heraklion, Greece|
A) to complete two widely-separated long profiles between Turkey and Egypt using the 160 cu.in bolt airgun, magnetometer and gravimeter. These lines were planned to cross the major east-west survery lines we completed on Shackleton in 1972 and thus to provide a means of correlating seismic reflection horizons between lines and to provide crossover checks of data from the complete survey. The lines were also planned to cross the previous tracks in regions of special geologic interest. Deployment of disposable sonobuoys was intended to provide important seismic velocity data needed for interpretation of all the seismic reflection profiling.
B) To carry out a bathymetric survey along the deep trench system south of Crete.
C) To complete seismic profiling along the lines supplementary to those of the 1972 Shackleton survey and complementary to the German earlier in 1974.
D) To complete a bottom sampling programme on the volcanic arc between Thira and Milos.
