String summary "Bute Inlet, a prominent fjord on the British Columbia coast, has been a site for moored, high-resolution measurements of surface seawater and marine boundary layer CO2 content since February 2025. Measurements of temperature, salinity, seawater and atmospheric CO2 partial pressure were collected from a surface buoy located in the central fjord using a MApCO2 System. This data contribution consists of measurements from February 15, 2025 to November 21, 2025.";

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.
