Dive Site Hazards

  • 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.

  • 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.

  • 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.
