45.36kmBubble Trapping Under Overhangs — Rock overhangs can trap exhaled bubbles, reducing visibility and causing disorientation.
Reflected Surge Patterns — Surge reflecting off rock faces can create irregular and unpredictable water movement.
Current Funnel Effect — Narrow gaps between rocks can accelerate water flow unexpectedly.
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.
Edge-Accelerated Currents — Currents often strengthen along drop-off edges.
Depth Perception Distortion — Visual contrast can distort perceived depth.
Terrain-Induced Descent — Divers may unintentionally follow terrain downward.
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.
Landmark Misidentification — Familiar sites can become unrecognisable at night.
Light-Induced Tunnel Vision — Focused light beams reduce peripheral awareness.
Depth Perception Errors — Reduced ambient light increases depth perception mistakes.
Remote Silt Disturbance — Silt can be disturbed metres away from the source.
Rapid Stress Escalation — Stress can increase sharply when visibility or navigation degrades.
High Cognitive Load Navigation — Complex passages increase mental workload even on a line.
