I dunno anymore, with all of the replenishment activities, sometimes it takes a hell of a lot to get down to any older conditions.
With a 15 foot surge, will create more of new rubbish layer, than uncover older layers.
Most older wrecks are discovered pretty deep, even near shore, so covering yes, uncovering, well....
A near shore wreck, uncovered with this storm, would likely have been uncovered long ago, and simply buried over again over time. Sand easily moves, but artifacts sink...That being said, a few scattered artifacts can be swept up and deposited, but I would doubt an entire shipwreck that is "new', or uncovering anything significant of a wreck that has not already been uncovered in the recent past.
