Ocean Data & Trust
This section covers data integrity, provenance, and auditability for ocean operations. As operations become more autonomous and data-driven, trust in data becomes essential for regulatory compliance, incident investigation, and operational decision-making.
Scope
This section addresses:
- Data provenance & chain-of-custody — Where data came from and who handled it
- Sensor calibration traceability — How sensors were calibrated and when
- Timestamp integrity — Ensuring timestamps are accurate and tamper-resistant
- Geospatial confidence & uncertainty — Understanding position accuracy and uncertainty
- Raw vs derived data — Distinguishing measured data from calculated data
- Audit logs & immutability — Creating tamper-resistant records suitable for audit
Key Principles
- Provenance matters — Data must be traceable to its source
- Calibration is critical — Sensor data is only as good as calibration
- Timestamps must be trusted — Time synchronization and integrity are essential
- Uncertainty must be quantified — All measurements have uncertainty
- Records must be immutable — Audit logs must be tamper-resistant
