55.84kmHidden Depth Variations — Complex reef topography can conceal depth changes, leading to unintended profile variations.
Distraction from Marine Activity — High fish activity can distract divers and delay depth or gas awareness.
Rapid Surge Direction Changes — Surge near reef structures can reverse direction quickly, pushing divers sideways into unexpected areas.
Unstable Visual Ascents — Relying on wall visuals can destabilise ascents.
Gradual Depth Creep — Lack of visual bottom reference can cause unnoticed descent.
Unsignalled Downcurrents — Downcurrents can form without visible indicators.
Gradual Narcosis Onset — Narcosis may develop slowly, making self-assessment unreliable.
Task Fixation at Depth — Cognitive narrowing at depth can reduce awareness of time and ascent rate.
Increased Gas Density Breathing Load — Higher gas density at depth increases work of breathing.
Eddy Pull-Off Zones — Eddies behind structures can pull divers away from the main drift line.
Delayed Surface Pickup — Strong current can exceed surface tracking assumptions, delaying boat pickup.
Vertical Current Shear — Currents may vary by depth, causing vertical separation even when divers stay together.
