RRS Discovery D104
Cruise summary report
|Ship name (ship code)||RRS Discovery (74E3)|
|Cruise period||1979-07-27 — 1979-08-19|
|Port of departure||Suez, Egypt|
|Port of return||Barry, United Kingdom|
|Objectives||1. The main objective was to use GLORIA to improve our knowledge of tectonic trend and style on the Hellenic Outer Ridge. In addition it was intended to map the extent of features attributed to submarine salt solution, discovered by GLORIA in 1977 and looked at in detail by the Scripps Institution of Oceanography Deep Tow system in 1978.
2. If time allowed it was hoped to compare the Hellenic trench system west of Crete with that part of the system to the south of Crete surveyed by GLORIA in 1977. Parts of this area had been previously looked at C.N.E.X.O. workers with their SEABEAM equipment, thus allowing comparative evaluation of the two techniques.
3. Opportunity would be taken to cross other geological features of interest during the passage to the U.K.
4. Sediment and pore water samples were to be obtained in order to examine the phenomena of sapropel formation and salt diffusion.
