Northern Arch
深度范围指从潜点顶部到通常最大深度；"建议认证等级"是运营商通常要求的主流机构等级，并非法律规定。水流和能见度每天都会变化，请将这里的所有信息视为规划参考范围。
Northern Arch is the Poor Knights at their most vertiginous: a slot cut clean through the headland, walls sheer on both sides, the floor far enough down that clear water plays tricks on the depth gauge. In late summer short-tail stingrays assemble here, stacking in the arch in loose formations that can number dozens, with kingfish spiraling above them. Orca occasionally arrive to hunt the same rays, which empties the arch faster than any dive computer alarm. Even without the megafauna, drifting the walls among sponge and jewel-anemone color is a top-shelf dive; with them it becomes the story of the trip.
您此行的高光时刻: Stingray squadrons in summer, sheer walls through the headland, occasional hunting orca
地形地貌: A deep vertical slot through the headland, walls dropping to about 40 m
水流: Flow funnels through the arch; crossing it can mean ducking into the lee of the walls.
入水前须知
危险因素: Depth deception in clear water and funneled current; plan the dive shallower than the arch invites.
保育: No-take reserve rules apply; give aggregating rays space and never block the arch ends.
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。
