Trust means being fixable. When we get a published number or claim wrong, we correct it in public and record it here — with the date and exactly what changed. To report an error or request the data behind a chart, email connect@marineradar.com, or see how the numbers are made on the methodology page.
Weekday breakdown was a normalisation artifact, not a weekly pattern
The seasonality page published a day-of-week breakdown that collapsed almost all signal onto one or two days. On launch-period data that is an artifact of how the index is scaled, not a real weekly rhythm, so the chart and the accompanying “peak weekday” figure should not have been presented as findings. Both are now withheld, with the reason shown in their place, until at least five of the seven days carry signal.
Explorer described attention figures as “AIS-driven”
Copy on the trends explorer described the figures as “AIS-driven”. They are not: they measure what people search for and open on MarineRadar, not ship positions reported over AIS. The wording has been removed and replaced with an accurate description of what the index reflects.
Growth figures floored, AIS source line removed
Extreme growth percentages produced by tiny denominators (e.g. “+40,100%”) were floored and capped. The “AIS network” source line was removed from stories, and attribution was reframed to state honestly how much of the signal is traced to a known source.
Frequently asked questions
When does MarineRadar issue a correction?
Whenever a published Trends number or claim turns out to be wrong — a misread figure, a misattributed vessel, or a conclusion the data did not support. Corrections are logged whether or not anyone reported the error.
What does each entry record?
The date of the correction, the story it applies to, and what specifically changed — the original claim and the corrected one, so the record is auditable rather than a vague note that something was updated.
Is the original story updated too?
Yes. The story is amended in place and its own revision date changes, so a reader arriving from search sees the corrected version rather than the error.
