Cruise summary report

Cruise Info. 
Ship nameFerder
Cruise identifier9/80 Leg 1
Cruise period1980-08-13 — 1980-09-04
ObjectivesLeg 1 of the "Ferder" drilling and site investigation programme.

Bad weather and equipment problems resulted in considerable loss of drilling time. 6 boreholes were attempted but only 1 was entirely unsuccessful. Consequently, much useful geological information was obtained despite hindrances encountered. Core recoverey ranged from a few percent to >90% in the core runs and the variation is attributable to various combinations of weather, bit types, bit weight, mud volumes and the experience of the driller.
