Multiple container shipping incidents and market reports
A spike in social media attention to container ships driven by multiple unrelated events: Iran's seizure of a container ship in the Persian Gulf, reports of a Russian missile attack on a container ship in Odesa, a trade union strike affecting container ships at Hamburg port, and routine market reports on container ship oversupply and charter rates.
Peak 49.4 on Monday 3 March 2025. The shaded band is the incident window.
Where the attention came from
Social-led, both over the window and on the peak day.
Bar = share of the extra attention over the whole window; the tick marks the share on the peak day alone, where the two differ.
How unusual it was
This was above 21% of all days since 2020, and the highest since Friday 14 February 2025.
How far it spread
No vessel type moved — 0 of 6 vessel-type groups drew clearly more readers than usual.
Readers here means readers of the Wikipedia article on each vessel type — the same source as the Research signal, not news coverage — so an incident can dominate the news without moving this panel. Bars start at 1× — normal readership for that vessel type, the weeks before the incident. Grey = no clear lift. "Over time" shows each group's daily readers through the window; "All 12 articles" breaks the six groups back into their members.
How it was framed the frame glossary →
Lead frame: engine of trade. Trade press was 0% of in-scope coverage — the story had left the trade press and gone mainstream. (Historical coverage is scored on headlines only.)
Acting, or acted upon
In 36% of coverage shipping was the thing acted upon rather than the actor.
How the coverage sounded
Coverage ran 55% negative overall; 27% strongly so.
Each article is scored on a five-step scale from strongly negative to strongly positive; the bar is the share of coverage at each step.
