String summary "This dataset contains all the chemical parameters measured during expeditions between May and October 2022 in the surface waters of Kamouraska's coastal waters. The data are divided into two databases. This database contains in situ data collected in parallel. Continuous pCO2 measurements were taken from the boat. A submersible pump was deployed from the side of the boat, pumping surface water into a degassing chamber connected to a CO2 analyzer (LI-830). Data are obtained every second, 5 seconds or 30 seconds depending on the expedition, and each measurement is coupled to a GPS position.";
String summary_fr "Ce jeu de données contient l’ensemble des paramètres chimiques ayant été mesurés lors des expéditions entre mai et octobre 2022 dans les eaux de surface des eaux côtières du Kamouraska. Les données sont divisées en deux bases de données. Cette base de données contient les données in situ récoltées en parallèle. En effet, des mesures de pCO2 en continu ont été effectuées à partir du bateau. Une pompe submersible a été déployée à partir du côté du bateau, permettant de pomper l’eau de surface dans une chambre à dégazage connectée à un analyseur de CO2 (LI-830). Les données sont obtenues à chaque seconde, 5 secondes ou 30 secondes selon l’expédition et chaque mesure est couplée à une position GPS.";

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.
