I need a list of historical or fictititious characters who died at sea and are 'buried' at sea, for example: The cast of Moby Dick,?

How long a list do you want.

The people who did not survive the sinking of Titanic (and were not picked up by the Mackay-Bennett and the other ship that was sent from Halifax to retrieve the bodies. The captains of those ships may have buried a few.)

The people who did not survive the sinking of Lusitania (and were not buried elsewhere)

Same for the crew and passengers of the Britannic (Titanic s sister ship that struck a mine and sank in the Aegean Sea).

Anyone - either Allied or Axis - that did not survive the sinkings of ships and U-boats during the two world wars. Also those in planes that were shot-down over the oceans.

You see, you are asking for much too much.

How about the USS Arizona Memorial at Pearl Harbor? There are over 1000 sailers and marines still aboard that sunken ship, part of the memorial serves as a shrine for them.
