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.
Misleading Line Tension — Line tension changes can give false cues about exit direction.
Cold-Induced Gas Consumption — Cold stress increases breathing rate and gas usage.
Reduced Failure Tolerance — Minor equipment issues escalate rapidly due to cold and dexterity loss.
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.
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.
Navigation Ambiguity — Lack of reference points makes exits harder to relocate.
Unnoticed Depth Drift — Featureless terrain can cause slow, unnoticed depth changes.
Camouflaged Hazardous Species — Hazardous marine life may remain unnoticed until very close.
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.
