String summary
"This dataset is comprised of sea surface temperature data collected using HOBO TidbiT MX Temperature 400 data loggers (MX2203) deployed in various locations across the BC coast but particularly in the Canadian portion of the Salish Sea. Loggers are suspended at 0.5 metres depth from floating docks in proximity to light traps as part of the Sentinels of Change project which monitors larval Dungeness crab (Metacarcinus magister) using light traps. The loggers are programmed to record the water temperature at 10 minute intervals, starting at 12:00 on April 15th until 12:00 September 1st, each year, starting in 2022. Loggers are removed from the water after September 1st and replaced the following spring before April 15th. These data will be collected each year until 2030.
This data package includes:
-Sea surface temperature data from April 15th to September 1st for 2022, 2023, and 2024 (the duration of the light trap collection season)
-Site metadata, including temperature logger location";

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.
