Quick answer: A full-resolution acoustic dataset is the complete, high-detail record from a scientific echosounder—stored ping-by-ping with depth samples and metadata. It matters because it enables quality assurance, calibration checks, reprocessing, and defensible reporting, even if you also transmit reduced “key indicators” during the mission.
| Element | Included in full-resolution | Why it matters |
|---|---|---|
| Ping records | Yes | Maximum detail for analysis |
| Depth samples | Yes | Enables layer interpretation and QC |
| Metadata (time/position/settings) | Yes | Traceability and correct processing |
| Reprocessing flexibility | High | Apply new thresholds or models later |
| File size | Large | Usually not suitable for continuous satcom transfer |
You typically get:
This is the dataset analysts want when they need to answer: “How sure are we?”
Live indicators are designed for speed and low bandwidth. They are excellent for:
But they are not a replacement for:
The full-resolution dataset is the “master recording.”
A common best practice is:
This gives both operational awareness and scientific defensibility.
Can we transmit the full-resolution dataset over satellite?
In most practical setups, not continuously. The volume is typically too high, which is why indicators exist.
Do we always need full-resolution for fisheries work?
If you care about traceable results, comparisons over time, or defensible reporting, full-resolution is strongly recommended.
What’s the difference between “raw” and “full-resolution”?
People often use them interchangeably. In practice, “full-resolution” emphasizes that the data hasn’t been reduced into summaries.
