No marine life details available.
Deceptive Entry Openings — Openings may become restrictive inside due to angle, collapse, or corrosion.
Surge-Induced Internal Silt Shift — Internal surge can move silt and debris without direct contact.
Partial Overhead Environment — Many wrecks limit direct ascent even without full penetration.
Fine Rust Particle Silt-Out — Disturbed rust particles can rapidly reduce visibility.
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.
