Signal Intercept
Hydrophone nine recorded a repeating envelope below civilian shipping noise. Pattern confidence is insufficient for classification, but sufficient to keep the log unsealed.
ACCESS // DECOMMISSIONED ARRAY
Operational Status
OP9 monitoring station was sealed after final naval review. The archive remains intact: coordinates, pressure tables, hydrophone logs, and the last intercept from beneath the shelf.

All lamps extinguished. Only the instrument face remains.
4000 M // ABYSS
The return ping never arrives.
OPERATIONAL LOG // FINAL ENTRY
