"Green, Salish Sea, 2d Depth-averaged Tracer Fields, Seasonal, v17-02

2d depth-averaged salinity and water temperature field values
averaged over 3 month seasonal intervals from Salish Sea NEMO model nowcast runs.
The values are calculated for the entire model grid that includes the Juan de Fuca Strait,
the Strait of Georgia, Puget Sound,
and Johnstone Strait on the coasts of Washington State and British Columbia.
The time values are UTC. They are the centre of the intervals over which the calculated model results are averaged.
The variable values are averaged over the upper 22 layers of the model grid,
approximately 0 to 30 metres depth.
Geo-location and depth data for the Salish Sea NEMO model grid are available in the ubcSSnBathymetry2V17-02 dataset.

v17-02: NEMO-3.6; ubcSSnBathymetryV17-02 bathymetry; see infoUrl link for full details:

Using griddap to Request Data and Graphs from Gridded Datasets

griddap lets you request a data subset, graph, or map from a gridded dataset (for example, sea surface temperature data from a satellite), via a specially formed URL. griddap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its projection 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.

griddap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/griddap/jplMURSST41.htmlTable?analysed_sst[(2002-06-01T09:00:00Z)][(-89.99):1000:(89.99)][(-179.99):1000:(180.0)]
Thus, the query is often a data variable name (e.g., analysed_sst), followed by [(start):stride:(stop)] (or a shorter variation of that) for each of the variable's dimensions (for example, [time][latitude][longitude]).

For details, see the griddap Documentation.
