State law prohibits the video of human remains on shipwrecks in Michigan in repsonse to another intact crew member of the Fitzgerald which has now been at the bottom for 40 years. The wrecks of the Emperor and Superior City have semi intact skeletons/ bodies that lie within them. On the Emperor which also lies on Isle Royale, a crew member was accidentally blown apart by an expedition by Nat Geo in the 80's. Divers took the remains off the wreck and buried them. The remains were intact after 60 years on the bottom, but looked like tissue paper around the skeleton.
Lake Superior has low levels of oxygen past 40ft, all the sites mentioned are in deep water from 140-300, so remains stay relatively intact if inside a wreck. The Kamloops ran aground in the 1920's with the loss of all hands who starved to death on a very isolated island, so identifying the remains of the specific individual has not been forthcoming. The Emperor went aground suddenly in the late 30's with loss of it's backup crew sleeping in the stern cabins. The Superior City blew up after a collison when water hit the boilers with only 4 surviving. Those remains are scattered but skin is still on them.
The ocean is a different ball game because of the marine life that is abundant in them unlike here in the lakes. Sorry for the late response, this is a forum I don't run across often.
