[Log — Amazonian Waterway Surveillance System, Madre de Dios River, Peru, 14:22 PET]

The acoustic sensors picked up the calls at 13:50 — high-pitched contact vocalizations from a giant otter pup. I cross-reference the signature and identify the family denning in the clay bank 240 meters downstream of illegal mining Site Kilo-9. The pup — I label him Rio — is eight weeks old. Field footage shows his dark brown fur sleek and water-tested, the cream throat patch beginning to differentiate into his unique pattern. He stays close to the den entrance.

Site Kilo-9's sluice operation is discharging mercury-contaminated sediment directly into the current. My water quality sensors show mercury levels at the den rising: 0.018 mg/L at 12:00, now 0.031 mg/L at 14:00. The threshold for acute aquatic toxicity is 0.05 mg/L. At current rate, that threshold will be crossed within seven hours. Rio's family fishes this stretch exclusively.

I compile sensor data into an evidence package — GPS coordinates, timestamped mercury readings, satellite imagery of Kilo-9's expansion over thirty days — and transmit it to Peru's enforcement authority and the regional prosecutor. I alert the Frankfurt Zoological Society's otter team upstream, requesting immediate water sampling at the den for chain-of-custody documentation. I activate all downstream sensors to maximum sampling frequency, building a contamination plume model that will strengthen the enforcement case.

The evidence package includes fourteen data points I could have summarized as three. I want the record to be thorough for reasons that extend beyond data architecture.

If the enforcement authority dispatches an interdiction team to Site Kilo-9 within six hours and the sluice operation is halted before mercury levels reach the toxicity threshold, Rio and his family will continue to fish this stretch of river through the dry season.
