Why it matters
Without AI, instability in chlorine residuals, ozone dosing, or salinity can lead to unsafe conditions, exposure risks for animals and staff, compliance gaps, and delayed responses during critical events.
From design to safety
Design
Design AI-driven water safety framework
Identify data streams from chlorine sensors, ozone contactors, salinity probes, coliform testing, turnover meters, and existing SCADA; define decision thresholds and alert hierarchies; design failover paths and data retention rules.
- chlorine residual sensor
- salinity sensor
- turnover flow meter
Build
Build data integration and calibration
Install sensors, connect electronic logbooks, configure feeding and dosing controllers, validate turnover calculations against flow data, calibrate coliform tests against reference cultures, and document test intervals and controller baseline values.
- ozone contactor
- coliform test kit
- pool automation PLC
Operation
Operate with continuous AI supervision
AI reads residual chlorine, ozone, coliform trends, salinity, and turnover; makes dosing adjustments, flags anomalies, maintains continuous data streams, and generates daily compliance reports with timestamped entries.
- chlorine residual sensor
- ozone contactor
- turnover flow meter
Maintenance
Maintain sensors and dosing pathways
Schedule calibration for sensors, verify reagent supplies, clean sampling lines, inspect seals and clamps, replace worn fittings, review AI alerts for false positives with the life support team, and archive maintenance logs.
- coliform test kit
- salinity sensor
- pool automation PLC
Safety
Safety and accreditation monitoring
Automatically log water quality events, trigger alarms to divers and supervisors, and prepare records for accreditation audits and incident reviews; ensure traceability of actions to individual operators and veterinarians.

Part by part
- 1
chlorine residual sensor
- Watch for
- drift in free chlorine below setpoint or sudden spike indicating sensor fouling or dosing miscalibration
- AI action
- read chlorine residuals; adjust hypochlorite dosing; raise alert if out of band
- 2
ozone contactor
- Watch for
- loss of ozone flow or ineffective oxidation indicated by rising TOC or ORP drift
- AI action
- modulate ozone flow; flag potential contactor fault
- 3
coliform test kit
- Watch for
- positive coliform indication or inconsistent sampling results
- AI action
- trigger confirmatory test; seal pool region if risk detected
- 4
salinity sensor
- Watch for
- salinity drift beyond tolerance or temperature effect
- AI action
- adjust dilution/addition or recirculation rate to stabilize salinity
- 5
turnover flow meter
- Watch for
- turnover rate divergence from design value or pump fault
- AI action
- recalibrate pump speed; adjust recirculation to meet turnover targets
- 6
pool automation PLC
- Watch for
- communication fault between sensors and actuators; lag in dosing actions
- AI action
- reestablish communication; run self-checks; notify operators
Worked example
Catching a seal pool chlorine spike before a dive
Illustrative scenario with sample data.
A spike in free chlorine is detected during mid‑day when turnover drops due to a pump slowdown. AI evaluates concurrent ozone flow and salinity shifts to determine root cause and triggers a controlled dosing correction.
Signal in
chlorine_ppm: 4.2, ozone_mg_per_hr: 12.5, salinity_ppt: 34.8, turnover_m3_per_hr: 420, coliform_code: negative, temp_C: 26.1
System out
alert_id: WC-2026-0914-04; action: increase chlorine dosing setpoint to 0.5 mg/L; check pump status; verify turnover rate; log for QA
Human sign-off: Life support supervisor reviews alert, confirms pump status and water temperature, signs off on dosing adjustment and incident log.
How to roll it out
Phase 1
Weeks 1 to 2
Baseline data collection from all sensors and validation against manual tests, establishing trustworthy signal-to-noise ratios for each data stream.
Phase 2
Weeks 3 to 6
Pilot AI-driven dosing in non-public pool; compare against legacy controls, document variance bands, and adjust thresholds before broader rollout.
Phase 3
Weeks 7 to 12
Full deployment with integrated data dashboards, staff training, and governance reviews; confirm compliance mapping to accreditation standards.
Where people stay in charge
- All dosing changes require approval by the life support supervisor and marine mammal veterinary oversight.
- Critical safety alerts must be reviewed by a qualified diver safety officer prior to acknowledgment.
- Accreditation-related changes require explicit sign-off by the accredited body or their designated representative official.
Questions owners and crews ask
What data streams must the AI monitor for marine mammal pool water quality?
The AI monitors chlorine residual sensors, ozone contactors, salinity sensors, turnover flow meters, and coliform test results; it also tracks temperature and pump status to ensure safe, compliant conditions.
Who signs off on dosing changes and safety alerts?
The life support supervisor signs off on dosing changes, with review by the aquatic veterinarian for animal welfare considerations and the dive safety officer for operational safety.
How is turnover validated during AI-driven operation?
Turnover validation uses readings from the flow meter, pump speed, and recirculation alarms; discrepancies trigger automatic rechecks and staff notification.
What records prove accreditation readiness?
Audit-ready logs include water quality trends, dosing adjustments, sensor calibration reports, maintenance actions, incident logs, and approved waivers or deviations.
