在泰国安达曼海研究圆孔珊瑚的标记，用于监测珊瑚礁健康

onitoring stakes fitted with small buoy floats rise from the surface of living Porites coral (Porites sp.) heads on a shallow reef, marking individual coral colonies for ongoing condition assessment. Porites are among the most structurally important corals on Indo-Pacific reefs, growing slowly over decades to form the mound and boulder formations that underpin reef architecture and biodiversity. The tension between scientific documentation and substrate disturbance is visible in this frame. 4K, vertical frame, medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
