In the Abyss

In the 1989 science fiction thriller film The Abyss, a search and rescue team descends thousands of feet into the depths of the ocean after a U.S. nuclear submarine mysteriously sinks in the Caribbean Sea. The word abyss could refer to both the oceanic zone that lies in perpetual darkness and to the more general space of mystery, fear, and awe in the face of the seemingly infinite expanse that the crew encounters, including an encounter with an alien being. Write a story that revolves around characters who find themselves in conflict with something deeply unknown and unfathomable. How might feelings of isolation surface or be exacerbated in such a situation? Play around with the pacing and order and quantity of revealed information to create a feeling of suspense.
