AI-Assisted Anomaly Detection in Ocean Sensor Data

What it collects
- Conductivity, temperature, and depth (CTD) readings collected from ocean sensors. These are physical measurements of the marine environment with no personal information attached.

What it is for
This system uses machine learning to automatically detect unusual patterns in conductivity, temperature, and depth (CTD) measurements collected from the ocean. It flags significant physical events in oceanographic data so that scientists can investigate them more closely. The system is used internally by Fisheries and Oceans Canada employees and does not process personal information.
What it collects and what happens to it
Data taken in
- Conductivity, temperature, and depth (CTD) readings collected from ocean sensors. These are physical measurements of the marine environment with no personal information attached.
Processing
- Machine learning models trained to identify unusual patterns or deviations in CTD time-series data, flagging significant physical ocean phenomena for scientific follow-up.
What it does
- Scores and flags CTD data records that deviate from expected oceanographic baselines, returning anomaly signals for review by scientists. Scientists decide which flagged events to investigate further.
Outputs
- Anomaly flags and scores applied to CTD data records, indicating which measurements represent significant deviations from expected oceanographic conditions. No personal information is produced.
- Highlights and prioritizes anomalous CTD records for closer investigation by scientists, effectively recommending which data points warrant further scientific attention.
Run by
- Federal department responsible for safeguarding Canada's waters and managing its fisheries and oceans resources. Deploys this system internally for use by its scientists.

How to read the colours
Can it identify you?
- Anonymized data
- Data about people with the link to who is broken. Stripped of identifiers, blurred, aggregated, or noised so this system can’t reasonably tie a record back to an individual.
- Pseudonymous data
- Each person’s data is tied to a token (hash, ID, template) that lets this system recognise the same person across events, but the token itself doesn’t reveal a name. Reidentification is possible with extra information.
- Identifiable data
- The data either contains a direct identifier (name, address, account name, recognisable face or voice, plate number) or carries a token this system uses to look up legal identity during processing.
Who completes the loop?
- Human decides
- This mode suggests; a person decides what to do next. The AI is always advisory — a human is in the loop on every decision. Example: a triage tool ranks cases for a clinician who chooses which to see first.
- Human executes
- This mode decides; a person carries out the result. Example: an optimizer plans the day’s trash-collection routes, and drivers run them.
- Autonomous
- This mode decides and acts on its own. No person reviews each decision or carries out the resulting action.
Definitions from the DTPR standard. Amber is about your data, violet about who decides. The fuller the shape and the deeper the colour, the more identifying the data or the less a person is involved.

Your rights
- Right to Algorithmic TransparencyThis system is publicly disclosed on the Government of Canada AI and Data Use Register. Citizens may consult the register entry for information about the system's purpose and scope. As it operates on non-personal oceanographic data, individual data-subject rights do not apply; however, the Government of Canada's broader open-government commitments support transparency about its AI systems.
Risks and safeguards
