Dive Site Hazards

Bubble 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.

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.
