Diver Surfacing Through Sargassum Beside Skiff

Misty gray light falls through a fine rain curtain, softening the edges of a white science skiff floating near the Shenzhen coast. A research diver breaks the water surface, their head and shoulders emerging from a thick mat of wet, brown sargassum seaweed. Droplets rest on the diver's black hood and the rubbery texture of the floating algae. The white hull of the boat sits just inches from the seaweed, its paint reflecting the flat, overcast sky. Water ripples spread outward from the diver's movement, disturbing the dense seaweed layer. A silver breathing apparatus valve glints faintly against the dark mask, while raindrops strike the water in tiny, concentric rings.
