On a recent scuba trip, I was loaned a Nikonos camera. Can anyone tell me whether the distance markings on the lens focus adjustment are for above surface or underwater measured camera-to-subject distance? (The owner didn't know and there was no manual.)

Unless I am misreading it the NIKONOS lenses are marked for measured underwater distances. For example setting the lens at 4ft is the same as 3 apparent feet underwater. It makes little difference since you will almost always use a strobe and rely on the depth of field to be sure the subject is in this depth of field range.
