Diver's Wet Slate with Reef Transect Numbers

Salt spray coats a black diving slate, leaving crystalline white speckles across its matte surface. Handwritten numbers in white chalk mark a reef transect, standing out against the dark background. The slate rests in the palm of a gloved hand, wet with seawater that reflects the bright late morning sun. Droplets rest on the edges, catching the light in tiny, sharp highlights. The background dissolves into a soft blur of turquoise and silver, suggesting the open water of Mombasa's coast. The chalk marks remain crisp despite the moisture, showing a precise, analytical record. One bead of water slides slowly down the corner of the slate, trailing a thin line of clear liquid.
