Observed ini
One row per dataset, one cell per year, darker with more observations — the same strip the front
door draws per dataset. Each row ends with the name that dataset uses (dataset_taxon);
the accepted name is written once, in the title above. A quiet pill marks a name the authority does not accept.

Every mark is a measured length with its own source — hover one to read it.
The reference objects are _data/size_reference.csv: two of them,
the 505 µm bongo mesh and the net's ring, are CalCOFI's own sampling gear.
