I have been working on an ocean-based Tarot deck for a while (at first I was calling it “La Mer,” an older French term for the ocean, until a friend pointed out calling your deck “Lamer” might not work out so well). The first card in the deck is The Fool, which represents taking the first step in the path you are following. The Rider-Waite deck shows a young man, his head in the air, walking toward the brink of a cliff, while a small dog barks to get his attention to what is about to happen.
In this version, a woman takes her first step into the sea with her spirit guide, in this case a spirit shark, glides silently by her side. The kelp part as they pass through, since once you know the language of the sea it will do anything for you. Because she is new to all this she must keep her head out of the water in order to breath; until she can master her fear of the unknown and begin swimming she will not be able to go very far, which is true with all of us when encountering something as vast and supernatural as the ocean for the first time.
