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.
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.
