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://comet.nefsc.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://comet.nefsc.noaa.gov/erddap/tabledap/erdGlobecBottle.htmlTable?longitude,latitude,time,bottle_posn,temperature1&time>=2002-08-17T00:00:00Z&time<=2002-08-19T20:18:00Z
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.
