Landmark Misidentification — Familiar sites can become unrecognisable at night.
Light-Induced Tunnel Vision — Focused light beams reduce peripheral awareness.
Depth Perception Errors — Reduced ambient light increases depth perception mistakes.
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.
