Jessie Beazley Reef

A solitary reef about 20 km north of the atolls, Jessie Beazley is the park in miniature: a crown of blinding white sand breaking the surface, ringed by coral slopes that tighten into walls. The isolation gives it the clearest water many trips see, often past 30 m, and a compact circuit that a single dive can nearly lap. Whitetips rest under table corals, grey reef sharks ride the up-current face, and pelagic wildcards, from devil rays to the odd whale shark, drift past on their own schedule. Liveaboards often stop here on the crossing home.

您此行的高光时刻: Exceptional visibility, a complete reef in one dive, pelagic surprises in open sea

地形地貌: Sand-crowned coral mound falling to walls on all sides

水流: An open-sea reef; current direction sets which face the boat works.

危险因素: Open-ocean exposure; currents wrap the reef and boats hold position rather than anchor.

保育: Part of Tubbataha Reefs Natural Park despite its distance from the atolls; identical rules and ranger patrols.

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）。
