String summary
"Partial Pressure of Carbon Dioxide relative to the Source time series data.
Platform: RV Sikuliaq
Sensor Model: Lamont-Doherty Earth Observatory pCO2 underway system
Sensor S/N: LI-6251 IRG1-338
Sensor Location Onboard: Wet Lab
Sensor Description: LDEO pCO2 Seawater Sensor; a system for the underway continuous measurement of surface water pCO2. The pCO2 system consists of several major components; a seawater/air equilibrator, the analysis enclosure (LI-COR 6251 infrared gas analyzer (IR), gas dryer, pressure sensor, A/D modules and gas stream selection valve), computer for system control and data logging, an enclosure holding a pair of air pumps for delivering the sample gas streams, 5 cylinders of CO2 in air calibration mixtures, 1 cylinder of nitrogen gas.
Parameter Description: The pco2 computed with conditions relative to the source. Users should review the source_id to identify atmospheric, equilibrator, and standard values.";

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.
