Dive Site Hazards

Thermocline Buoyancy Shift — Sharp thermoclines can cause sudden buoyancy changes.
Instant Visibility Collapse — Sediment disturbance can eliminate visibility immediately.
Late Detection of Structures — Submerged structures may only appear at very close range.

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.

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.
