Human: Make a concise location description of a serene scene outside coastal area with sand, kelp, and shells. Assistant: 
The beach slopes gently down to the sea, its moonlit sand broken here and there with dark splotches created by piles of kelp washed up at high tide. A stretch pocked by broken shells marks the edge of the more closely packed sand still awash from cascading waves. The roar of the surf is a constant background melody, its song timeless and languid.
