Exploring the Sunken Sundial
A mermaid with long braided hair glides around a stone sundial positioned on the ocean floor. The carved timekeeping instrument features sculpted hour markings resting directly on the sandy seabed. Sunlight filtering down through the sea surface illuminates the ancient stone surface.
Timekeeping and Sunlight Beneath the Waves
Sundials require direct sunlight to cast shadows and measure time accurately throughout the day. While surface sundials rely on clear skies, light penetrating shallow seawater decreases rapidly with depth due to absorption and scattering. In coastal waters, sunlight usually reaches down to a depth of around two hundred meters, where underwater shadows can still form in clear conditions.
Colors of Sundials and Ocean Environments
- Carved stone sundial: sandstone beige, granite gray, and mossy green
- Mermaid braids and hair: golden blonde, auburn brown, or dark chestnut
