Access
Every endpoint this dataset can be reached through, grouped by how you would use it. Every URL is in the release record and answered when the release was cut.
Explore
Apps that read this dataset from the release. A row marked “this dataset” opens with it already selected.

Query
SQL against the release itself, in the browser — nothing to install and nothing downloaded until a query asks for it. __TBL:obs__ resolves to the pinned release’s parquet.

Files from the release (Parquet)
The frozen objects this release is made of. A partition holds only this dataset’s rows; a shared table holds every dataset’s, so filter on dataset_key.

CF netCDF
One self-describing file, for a tool that reads netCDF.
how far this file is CF
Fully CF: an underway series on a moving platform is a CF trajectory. One trajectory per cruise; time, latitude and longitude vary along the observation dimension rather than being fixed per instance.

ERDDAP (erddap.calcofi.io)
One ERDDAP dataset per grain, each with its own data formats and its own pages. Subset in the browser or query it from a script.
- full resolution (pre-thinning)
- the unthinned series, every bin as the instrument recorded it
- observations
- one row per measurement, joined to the event it was taken on
- sampling events
- one row per cast, tow or transect — when, where and how it was sampled
