One (speculative) suggestion I'll offer is that although each arc may have an amount of error if you assume a constant speed then that will help 'respace' them. So if the hourly arcs were notionally 420, 460 and 450 nautical miles apart you could calculate an assumed average speed of ~435knts and replot the lines to fit that assumption.
Has anyone see a 'back plot' from Ocean Shield's search position across the satellite arcs at various speeds to see if it leads back to the right origin?
Alternatively, as I think we mentioned above, I wouldn't be surprised if a submarine from some nation or other had passed by the area in the last month and detected something to help direct the surface search.
