Dissolved inorganic carbon replicate 1
The registry carries no authored label for this measurement, so the name above is the canonical series' own description in metadata/measurement_type.csv (variable.csv holds the authored labels, five today).

series
dic_rep1· source columndic1· flag columndic_quality_commentreplicate
One row per series, one cell per year, darker with more values — the same strip the front door draws per dataset and a species page draws per taxon. Each row is one dataset's own measurement_type; the label is written once, in the title above.
By depth
Values per depth band at the release grain, one thin bar per series. The bands are the record's own (0-10 … 2000+ m).
By month
Values per calendar month, one row per series: CalCOFI's quarterly cruises show as peaks in the months the ships sail.
Range & quality
- bounds
- The registry declares
0 … 5000 µmol/kgfordic_rep1; a value outside it is dropped at the ingest (drop_out_of_bounds()). - observed

- Hydrographic Bottle
dic_rep1carries no quality code at the release grain (its source column isdic_quality_comment); qual_ok keeps all 1,999. - baseline
- A monthly climatology exists for this measurement (the release's climatology table: 1993–2013, dataset × grid cell × calendar month × 10 m bin), so the Explorer can draw anomalies against it rather than values.

The same quantity from another platform or another kind of sample, each its own page and never merged into this one: a dataset's own bottle samples would count that dataset twice, an underway intake is not a cast, and a replicate is not a mean. The reason is the record's (related[].why).
