Sunken Island

South of Moalboal's shore reefs, a seamount climbs from serious depth to a plateau in the mid-teens, and everything about diving it feels bigger than the house reef routine: the blue descent with no wall for reference, the current pushing schools of jacks and rainbow runners over the crown, barracuda hanging upcurrent like weathervanes. Whitetips cruise the flanks, and the coral on top stays surprisingly lush for a spot with this much water movement. It is Moalboal's advanced-ticket dive, weather-dependent and occasionally humbling, the one local divemasters do on their days off.

您此行的高光时刻: Blue-water seamount descent, schooling pelagics over the crown, big-dive atmosphere minutes from town

地形地貌: Coral-capped seamount rising from deep water

水流: Exposed to open-channel flow; the dive is planned around slack windows and aborted without shame when it rips.

入水方式: A blue-water descent onto the plateau, usually via negative entry when current runs; dived from Moalboal and Badian boats in good weather.

危险因素: Strong current, no fixed reference on descent, and depths that invite overstaying; surface marker mandatory.

高氧（Nitrox）: 在此值得使用——各潜点深度落在富氧空气（nitrox）能有效延长免减压时间的区间（前提是持有相应认证）。
