Sample value from the publisher’s release
2023: 7,513 possible detections · 2,464 verified on site (41%) · up 58% on 2022
Detections are POSSIBLE pollution. A radar signature may come from mineral oil, but equally from an algal bloom, upwelling, sewage or garbage. Only 41% were verified on site; reading the raw detection count as a count of infringements is wrong.

Sample value from the publisher’s release
More than 10,000 incidents recorded · 24.5 large (>700 t) spills per year in the 1970s · ~5.88 million tonnes in total 1970–2022 · spills over 7 t down by more than 90% since the 1970s
Covers only accidental spills from tank vessels; operational discharges and pipeline or platform spills are outside it. A single large casualty can determine an annual total on its own. The downward trend is not normalised by fleet size.
