Mary Island

Mary Island, Mborokua on the charts, is an uninhabited volcanic cone in open water, and its points are fish traps in the best sense. Barracuda school here in genuinely huge, rotating columns; bigeye trevally form a second storm below them; and gray reef sharks thread the whole structure while dogtooth tuna make passes from the blue. The reef itself is sturdy rather than delicate, built for the current that feeds it. Dives run as slow drifts along the points, divers tucked against the slope watching traffic. Between the crowds of fish and the absence of any village, the island feels like the Solomons with the volume turned all the way up.

您此行的高光时刻: Barracuda columns in the thousands; trevally storms; steady gray reef shark traffic on the points.

地形地貌: Steep volcanic reef slopes and points dropping into deep, clear open water

水流: The points concentrate flow, and the fish concentrate with it.

入水方式: An uninhabited volcanic island between the Russells and the New Georgia group; liveaboard territory, dived on the points where current runs.

危险因素: Current on the points; open-water exposure and long liveaboard distances from help.

保育: An unpopulated island whose reefs stay rich precisely because visits are few: no anchoring on the points, no take of any kind.

高氧（Nitrox）: 在此值得使用：这些潜点的深度范围内，富氧空气（nitrox）能有效延长免减压停留时间，前提是您已接受相关培训。
