Indeed. This is a bit puzzling but on the other Hand that doesn't necessarily mean they are searching in the totally wrong area.
If the waterfall graphs were the real deal and it wasn't accidentally generated in the measuring device itself (which I hope they are examining), I would say there is very big chance it was from MH370. It looked perfectly constant in amplitude and frequency and the duration of the Signal seemed to match as well.
Natural phenomena won't achieve that in any likelyhood.
However, some querstions remain: Is Bluefin21 working as advertised?
Would it really detect shattered debris in silt?
And more importantly: How far do these signals really travel. Looking at the on/off nature of the detections, it looked more like signals that were channeled over a longer distance, leading to relatively short detection times (in some instances only minutes). At 2kts, a detection of 15 minutes means a length of 0,5 km. Perhaps behaviour of such signals in cold water under high pressure is not really 100% understood, yet.
Anyway, they will look at the results of the scans and be able to decide if Resolution was suffcient to 100% exclude they travelled over it.
Depending on that it would be: Either different Equipment (Abyss? Remus?) or enlarged Search area.
