String summary "The Trinidad Head glider line aims to extend the time series of sustained glider-based measurements off the California that begun in 2014. Seaglider and SGX underwater gliders repeatedly occupy a single section that extends offshore from the continental slope to 40.05N, 129W. Gliders profile from the sea surface to 1000-m depth and back every 6 hours while traversing the line at a speed of roughly 20 km/day. The Trinidad Head line is sampled by a single glider, which is replaced as needed to maintain continuous occupation of the section.";

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.
