The lines seen here show the paths taken by ships using sonar to map small sections of the ocean floor in greater detail. The gridded section shown above may look like streets in a small town but is over 100 miles wide. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. The area above is one of the more frequently cited underwater city locations in online lore.

The scripps sea floor map has also been used to discover a new microplate in the indian ocean. Most of the ocean bathymetry data comes from satellite measurements of gravity. The pattern you are seeing is typical for a research vessel surveying a patch of ocean floor. The grid lines are most likely a processing artifact.

This is a list of ocean liners past and present which are passenger ships engaged in the transportation of passengers and goods in transoceanic voyages. The gravity data are cross checked against ship sonar tracks from a variety of vessels. Major lines of data tend to cross into american borders and territorial water making.

Cables located at shallow depths are buried beneath the ocean floor using high pressure water jets. I was playing around with google earth a while back and noticed something strange on the ocean floor.
