  Re-terminated FRRF Deck Box power cable due to various power 
  problems.
    
  PRR cast :
    
    On the downcast, the light, tilt & spin sensors went "bad" at around 
    100m. Once the PRR got to the bottom, the signal recovered. Everything
    appeared OK on the upcast. We tried a second time, lowering at a 
    slower rate. It seemed to do better, but still went "bad" around 120m.
    Was this due to a dramatic density layer? I don't know.
