Subject: Weaving across scarp crest producing overly peak-strewn SBP record

Kongsberg SBP120 Sub-Bottom Profiler [view]

Action: caution

As with Line 14 we are tracking along a uppermost slope to shelf-break scarp that is approximately 15 metres high.

This is producing a very peaky (lumpy-bumpy inverted parabolic peak) record which is not reflective of pinacles but is a consequence of the ship& 39;s weaving back and forth across the scarp crest. That is we are repetitively transitioning betwee a lower relatively flat surface and an upper flat surface
