    String description "The daily sampling strategy at BC shore stations was designed long ago by Dr. John P. Tully. We have chosen not to change the strategy in the interests of a homogeneous data set. A sea water sample is collected by immersing a bucket in the seawater and measuring the temperature and salinity of the water in the bucket; sampling occurs at or near the daytime high tide. Sampling at the daytime high tide means, for example, that if an observer starts sampling one day at 6 a.m.(local time) and continues to sample at the daytime hightide then on the 2nd day the sample will be taken at about 06:50, the next day at 07:40 and so on. When the daytime high tide occurs in the late afternoon the sampling time reverts to the next morning and the cycle starts again. Since there is a diurnal signal in sea-surface temperature the sampling creates a 14-day signal as an artifact in the daily data. The monthly data are calculated by averaging the daily data of each month.";

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.
