Still waiting to resolve our camera problems we are bashing it big time with sidescan sonar right now. Scouring the seabed this year for aeroplanes and not knowing what we are going to find be it large or small is all consuming. The data is gone through time and again just in case we missed something first time around. We view it from different angles, use different colours, look at it close up and stand back and look from a distance trying to spot anything that may have come from an aircraft or at the very least is man made. When a nice 90 metre long shipwreck comes into view it does make a pleasant change! No point in wondering what this is? Job done tis a big ship.
