Zeroninesevenone,
All the contour lines in the blurred area are in line and linear with the rest of the contour. It is just darker, so I'd say that the blurring is because there is sand/mud flying over the central area, perhaps because the ROV has moved the box a bit to see if the CSMU is there or not. Definitely not because of any alteration.
Maybe you´re right. Anyway, thank you for demonstrating to some uneducated fellas here that THERE IS a blurr after all, and it is not a figment of my imagination!
