Hidden 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.
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.
Situational Awareness Loss — Divers may fixate on sharks and lose depth or position awareness.
Subtle Behavioural Shifts — Changes in shark behaviour may be missed without active observation.
Blue-Water Reference Loss — Lack of visual references increases ascent and descent instability.
