Samples were collected regularly from 10 sites around the periphery of the island, and from 4 sites at increasing distances from the island following spring tides. Additional data were collected adjacent to a site with high-resolution sampling of water conditions in 2001, 2015, 2016 and 2022. Samples were filtered through GF/F filter paper, frozen, and shipped to the University of Washington Marine Chemistry Laboratory for analysis of NO3, NO2, NH4, PO4, and Si(OH)4. The data provide a picture of long-term nutrient dynamics in the eastern Pacific Ocean at the entry to the Strait of Juan de Fuca.";

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.
