Hi Tom
It has been a while, am not aware of any software you could use which can give u a better idea of what were seeing in sonar image obviously we know were 2012 debris field is, I think more needs to be done to a certain were exactly the 2010 wire/rope video was filmed allot of people including Ric and Jeff don't see anything I do an I bet the video was taking some were along that gouge that leads to anomaly,
The be all an end all though is untill we go back we don't know what it is for certain.
Just hope we don't have to wait till 2014 to find out i could get struck by lightning or knocked over by a plane before then haha
