Trying to find submarine sphere?

Hi,

I found the underground puzzle with the mark I armor pants and the key to the "submarine sphere".  I found a submarine wreck but no spehere.  Anyone have any idea about how many sub wrecks are in the game and any tips for finding them? 

Please help.

I didn't find the right solution from the Internet.
