It matters because it enables **quality assurance, calibration checks, reprocessing, and defensible reporting**, even if you also transmit reduced “key indicators” during the mission. ## Key facts | 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 | --- ## What you “get” in a full-resolution dataset You typically get: - The complete acoustic record (not averaged down) - The ability to regenerate echograms and derived products - The full context required for QA (dropouts, changes in settings, artifacts) This is the dataset analysts want when they need to answer: “How sure are we?” --- ## Why it matters (even if you have live indicators) Live indicators are designed for speed and low bandwidth. They are excellent for: - Steering missions - Detecting changes in distribution patterns - Reporting quick operational updates But they are not a replacement for: - Calibration checks - Detailed noise handling - Auditability and reprocessing - Robust comparisons across campaigns The full-resolution dataset is the “master recording.” --- ## How it connects to “transmitting key indicators” A common best practice is: - **Transmit indicators** during the mission (compact summaries) - **Recover full-resolution** after the mission (deep analysis) This gives both operational awareness and scientific defensibility. --- ## Practical checklist for using full-resolution data well - Keep settings consistent across transects when possible - Log navigation metadata continuously - Record changes (maintenance, configuration) - Run systematic QC before producing final maps and trends - Archive with clear versioning and mission notes --- ## FAQ **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. ### Related Articles ##### [![Explained by Offshore Sensing: Autonomous platform emissions and sustainability in marine research](https://sailbuoy.no/hs-fs/hubfs/Hubspot%20blog%20feature%20image%20explained%20by%20offshore%20sensing%20(1).png?width=520&height=294&name=Hubspot%20blog%20feature%20image%20explained%20by%20offshore%20sensing%20(1).png) Explained • June 2, 2026 Explained by Offshore Sensing: Autonomous platform emissions and sustainability in marine research](https://sailbuoy.no/news/explained-by-offshore-sensing-autonomous-platform-emissions-and-sustainability-in-marine-research) ##### [![Explained by Offshore Sensing: Arctic and polar ocean monitoring with autonomous platforms](https://sailbuoy.no/hs-fs/hubfs/Hubspot%20blog%20feature%20image%20explained%20by%20offshore%20sensing%20(1).png?width=520&height=294&name=Hubspot%20blog%20feature%20image%20explained%20by%20offshore%20sensing%20(1).png) Explained • June 2, 2026 Explained by Offshore Sensing: Arctic and polar ocean monitoring with autonomous platforms](https://sailbuoy.no/news/explained-by-offshore-sensing-arctic-and-polar-ocean-monitoring-with-autonomous-platforms) ##### [![Explained by Offshore Sensing: Continuous ocean time-series data: why gaps in observation cost science](https://sailbuoy.no/hs-fs/hubfs/Hubspot%20blog%20feature%20image%20explained%20by%20offshore%20sensing%20(1).png?width=520&height=294&name=Hubspot%20blog%20feature%20image%20explained%20by%20offshore%20sensing%20(1).png) Explained • June 2, 2026 Explained by Offshore Sensing: Continuous ocean time-series data: why gaps in observation cost science](https://sailbuoy.no/news/explained-by-offshore-sensing-continuous-ocean-time-series-data-why-gaps-in-observation-cost-science) [![Offshore Sensing_original_logo_fixed](https://sailbuoy.no/hubfs/Logo%20and%20Icons/Offshore%20Sensing_original_logo_fixed.svg)](https://sailbuoy.no) - [Book meeting](https://sailbuoy.no/contact) - [Build your Sailbuoy](https://sailbuoy.no/unmanned-surface-vessels) - [Explained by Offshore Sensing](https://sailbuoy.no/explained-by-offshore-sensing) - [Resources](https://sailbuoy.no/resources) Offshore Sensing AS Sandslimarken 31 5254 Sandsli, Norway   [Crowdworks Company Profile](https://app.crowdworks.it/companies/offshore-sensing/update) ©2026 Offshore Sensing AS.
