==Quality control==

It is essential to have stringent but fair quality control (QC) specifications on each and every aspect of the marine seismic data acquisition system. Air guns will break. The QC specifications must address how many air guns can fail before acquisition must be terminated for repair. Things will go wrong with the streamer cable. How many channels can go bad before the cable must be repaired? Sometimes there are other seismic crews in the area. How much interference noise<ref name=pt07r36>Lynn, W., M. Doyle, K. Larner, and R.

The details of this very important subject are beyond the scope of this note, but in my opinion, it is almost as easy to keep things running at 90 to 100% capacity as it is to keep things running at 70 to 80%, so it makes sense to demand high performance.
