Your photo taking was of objects not at all far from lens. An underwater camera, with a long distance between subject and lens there is much more suspended matter in the water to block/attenuate the quality of the image captured by the camera.
In my navy diving days I was the go-to guy with the Nikon's and video gear. In awful harbor water (with the opacity and purity of an unflushed bus-station toilet) I got good shots (prairie-masker belts, and dinged propeller blades), but only by careful lens selection, off-set flash, and getting the lens right on top of the work. And burning up a lot of film by bracketing each shot.
The longer the distance between camera and the work, the more ****ty the resolution.
And that's another reason combatant submarines don't have windows.
