Shark Airport

The name is literal: a broad runway of pale sand at around 18-20 m on North Atoll where whitetip reef sharks park in rows, ruffling off only when divers drift too close. The shelf tips over into a wall streaked with sea fans and anemones, and the transition line is where the action stacks up, with grey reef sharks holding in the blue and eagle rays or a lone manta passing at the edge of visibility. It is an easy, readable dive by Tubbataha standards, which makes it a common season opener before the wilder corners.

您此行的高光时刻: Rows of resting whitetips on sand, grey reef sharks off the wall, chance of rays cruising the drop

地形地貌: White-sand shelf over a sheer wall

水流: Usually a relaxed drift along the wall; the corner can accelerate without much warning.

危险因素: Current picks up at the corner; the wall drops well past recreational depth.

保育: Inside Tubbataha Reefs Natural Park; strict no-touch, no-take rules under ranger watch.

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）。
