The following account was recorded in the agent's log during your transmission: Umm, massive crystal shards are jutting out of the seafloor, illuminated by faint, blue-green light filtering down from above. The water's icy cold and the pressure's extreme, but somehow, like, the shards are emitting this low hum that's almost a vibration. Air bubbles are trapped inside the crystals, and they're slowly moving upward, but somehow staying within the crystal structures... a shark's skeleton is lodged inside one of the shards, its jaws wide open like it got stuck there.
