Figure 4-13.— Schematic of the Argo-Jason Deep-Sea Photographic System 



The Argo-Jason system is currently under development at Woods Hole's Deep Submergence Laboratory. Argo has already 

 assisted in locating the Titanic. Jason is being designed to be launched from Argo and will handle detailed camera worl<.

and related marine data transmission needs. How- 

 ever, before fiber-optic cables can be employed, 

 problems of handling tensional stress and repeated 

 flexing of the cable must be overcome. Personnel 

 at DSL believe that when the Argo-Jason system 

 is fully developed, the need for manned submersi- 

 bles will be much reduced. 



The current subject-to-lens range limit for opti- 

 cal imaging is 30 to 50 meters in clear water. Sev- 

 eral improvements are expected in the future that 

 may enable subjects to be imaged as far as 200 

 meters from the lens under optimal viewing con- 

 ditions. For instance, work is underway to increase 

 the sensitivity of film to low light levels. A 200,000
