What this is
Every dataset CalCOFI holds: the 20 in the integrated database, each with
its coverage, every endpoint it can be reached through and how to cite it, and the
15 holdings that are not in the database yet. One page per dataset. The
machine-readable catalog is data.json and
sitemap.xml .
Rows open to the description, what is in them and the ways in.
