    String summary "This dataset includes measurements of the partial pressure of carbon dioxide (pCO2), temperature, and salinity made on seawater drawn continuously from a 20-m intake at the Bamfield Marine Sciences Centre in Bamfield, BC, Canada. The collection of these data utilizes a Burke-o-Lator (BoL) pCO2/TCO2 analyzer and began August 30, 2023. The Burke-o-Lator (BoL) pCO2/TCO2 analyzer measures carbon dioxide partial pressure (pCO2) and total dissolved inorganic carbon (TCO2) from a flow-through seawater stream and from seawater collected in discrete samples. The BoL is paired with a SBE 45 Thermosalinograph to measure seawater temperature and salinity. These data provide valuable information on patterns in marine carbonate chemistry and ocean acidification within Barkley Sound waters being supplied to the Bamfield Marine Sciences Centre and the Nova Harvest Ltd. shellfish hatchery.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

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.
