Check out these lines on the seafloor. (You may need to zoom in or out to see the tracks).

These lines hold a very consistent width along their length even around curves. It looks a lot like tracks made by a man made vehicle or perhaps the track of a pillbug.
The thing is the scale would make this an enormous vehicle or animal.
I thought at first it might be lines from seafloor spreading, but there are areas where it loops over itself and places where it resembles the track a snowplow might take back and forth to clear a parking lot.
Anyone know what causes these? Speculation is also invited.
