This thought just hit me.

With the great leaps in technology I would have to imagine the crews could produce quality charts of the substrata, to reasonable depths (not 40K feet) using much smaller charges of gel and det cord. For the crews using air guns, well they could probably get great results out of single gun arrays rather than the triple gun arrays we developed.

We ran four triple arrays, which would literally shake the boat apart. The air blast would incapacitate fish (but not kill them) and really churned the sea bed in the shallows.

With so many traces and being able to chart so deep it appears to me that doodlebugging can be ecofriendly in the very near future.
