You could find the cities that were in Numenor and Beleriand underwater and you can find chests inside with books of lore and artifacts and loot. You can sometimes stumble upon a sealed underwater orc dungeon in underwater Beleriand and underwater parts of Angband that survived the last of the Wars of the Beleriand.
