THRESHOLD LOG 11-H8

Designation: Refrigeration Chamber R-14

Apparent timestamp: 14:02 / 02:51 / 14:02

Entry method: Horizontal hatch from service corridor

Environmental Baseline

Fluorescent tube arrays, 3500K, intensity 62 lux. Flicker rate measures 0.0 Hz.

Ambient temperature 3.1°C. Humidity 91%.

Air pressure elevated by 18 hPa relative to external baseline. Instruments register stable positive pressure.

Background sound consists of continuous low-frequency hum at 48 Hz. Source remains unlocated. Air movement is absent.

Spatial Observations

Chamber dimensions measure 8.4 m by 6.1 m by 3.2 m. Estimated volume 164 m³. Measured volume by laser scan 119 m³.

Walls: white ceramic tile with grout lines spaced at 0.15 m. Tile pattern repeats every 2.1 m in both horizontal axes.

Floor: seamless stainless steel. Condensation forms in concentric rings centered on no visible feature.

Ceiling contains six identical ventilation grilles. Airflow from grilles registers zero.

Shelving units line the longer walls. Unit height measures 2.8 m. Shelf spacing is 0.4 m. Counted shelves per unit total 8. Calculated coverage for 2.8 m requires 7.

Anomalies

Contents of shelves phase between solid and translucent states at irregular intervals of 11 to 37 seconds. Transition is silent.

Frost accumulates on surfaces at a rate of 0.3 mm per minute. Ambient temperature remains constant during accumulation. Frost sublimates without change in humidity readings.

Laser rangefinder aimed at far wall returns values alternating between 6.1 m and 9.7 m. Physical measurement with tape yields consistent 6.1 m.

Elapsed time on recording device is 28 minutes. External chronometer shows 51 minutes elapsed.

Condensation rings expand at 1.2 cm per minute. Rings remain centered on empty floor space. Center point drifts 4 cm north with each expansion cycle.

Shelving unit depth measures 0.6 m. Objects placed on shelves remain visible from both sides of the unit simultaneously.

Entity Notes

None recorded.

Exit / Continuity Status

Exit achieved through original horizontal hatch after 33 minutes subjective.

Shelf count on final observation totaled 9 per unit.

Residual effect: tactile sensation of cold persists on exposed skin for 12 minutes after exit despite measured skin temperature return to baseline.

Recording device clock runs 0.7× external reference for the duration of residual effect.
