String summary "Bedford Basin, Nova Scotia, has been host to frequent monitoring by the Department of Fisheries and Oceans (DFO) at the Bedford Institute of Oceanography (BIO) since the 1960s. This monitoring was formalized as the Bedford Basin Monitoring Program (BBMP), a weekly time series, in 1999. Dalhousie University joined the BBMP in 2008 to begin a bio-optical time series, beginning a close relationship between academic and government researchers. This dataset consists of data collected by a Bio Optical Profiler (BOP)which is a series of instruments mounted on a large cage. There are no measurements taken in August of each year as the vessel is away for maintenance. The Bedford Basin station (BB1) is at 44.693611 N, -63.640278 E and has a maximum depth of 73 m, though the instruments are typically only sent to 60 m. Calibration coefficients are available upon request.";

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.
