THROUGH TIME
Time series
Gaps are not connected and values are not interpolated. The vertical axis scales to the data range. Exact values are available in the table below.
Latest records in the selected range
Each value is labelled with its own period; publication schedules may differ.

READING GUIDE
The right scale. A fair comparison.
Ocean measures / contextual indicators
Marine protection and sea temperature are direct indicators; fisheries totals that include inland waters are labelled as context. National energy, carbon and economic series provide context; they do not measure the maritime sector’s share.
One indicator, a shared period
Each chart contains only series for one indicator in the same unit. Comparison bars use the latest period shared by all selected entities. Read geographic coverage and source notes together.
Gaps stay visible
Missing observations are never converted to zero. Monthly and annual series are not mixed. This package is a dated data snapshot, not a live feed. Read provider estimates together with the source notes.
