missing submarine: No food or water, it's designed to dive, look around and return to surface

32. There are factors not being mentioned, for obvious reasons.

Take a look at this link at this article - A Geological Study of the Titanic Shipwreck Site

No matter if the submersible's hull remained structurally intact or not, the currents in that area of the ocean are quiet strong and could potentially transport it far from the dive site, even if it descended directly to the bottom. It is possible that it did not reach bottom and could be moving still, and at an unknown depth.

After the collision, the Titanic and its debris came to rest in the region of the North Atlantic Ocean where two major underwater currents converged. This region is near the continental shelf of Newfoundland called the Grand Banks.

The water moving through the area originates from the warm waters of the Gulf Stream which flows northward along the eastern seaboard of the eastern United States. The second current of cold water called the Western Boundary Undercurrent starts around Greenland and Labrador and flows southwesterly along the United States continental shelf. These currents are probably the reason why the debris from the sinking is scattered over such a large area, not to mention the remains sunk nearly 2.5 miles below the sea level.

The shipwreck is in a canyon surrounded by three low mountains on three sides, each rising approximately 2,000 feet from the ocean floor. The mountain west of the site is 30 miles away. The second one is 20 miles south of it, and the closest one is 17 miles north of the site.
