Dive Site Hazards

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.

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.

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.
