Scientist Holds Sediment Core Rio Morning Light

Soft, overcast daylight fills the space where a scientist stands holding a long sediment core tube. The cylindrical sample reveals distinct layers of dark earth and lighter sand, its wet surface reflecting the gray sky. Behind the figure, low-hanging clouds obscure the tops of Rio de Janeiro's lush green hills and scattered white buildings. The rain-soaked pavement glistens with puddles mirroring the muted sky. Symmetrical framing centers the researcher against the hazy urban backdrop, showing the texture of the mud and the dampness of the early morning air. A small drop of water rests on the rim of the core tube, tracing a path down the gray plastic.
