String summary "Zooplankton net-tow sample registry from the SIO Pelagic Invertebrate Collection, scoped to CalCOFI-program expeditions. Position, time, depth, and gear metadata per tow. Includes the historical grid (1950s-80s inshore, Gulf of California and Baja lines), not just the modern pattern. Biovolume measurements are not in the source file and are pending from the provider (see Questions for Data Providers). One row per sampling event, with event-level effort widened into its own columns. Use this for effort and station counting — summing effort over the observation table double-counts it. Source: CalCOFI integrated database release v2026.08.08.";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
