    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.";

    String summary 
"\"Daily sea surface temperature and salinity observations have been carried out at several locations on the coast of British Columbia since the early part of the 20th century. Observations started at the Pacific Biological Station (Departure Bay) in 1914; 11 stations were added in the mid-1930s and several more in the 1960s. The number of stations reporting at any given time has varied as sampling has been discontinued at some stations and started or resumed at others.
Presently termed the British Columbia Shore Station Oceanographic Program (BCSOP), there are 12 participating stations where daily sea-surface temperature and salinity measurements have been collected from 1914 to present. Due to unfavourable sampling conditions, there are some gaps in the daily data.
Observations are made daily using seawater collected in a bucket lowered into the surface water at or near the daytime high tide. This sampling method was designed long ago by Dr. John P. Tully and has not been changed in the interests of a homogeneous data set. This means, for example, that if an observer starts sampling one day at 6 a.m., and continues to sample at the daytime high tide on the second day the sample will be taken at about 06:50 the next day, 07:40 the day after etc. When the daytime high-tide gets close to 6 p.m. the observer will then begin again to sample early in the morning, and the cycle continues. Since there is a day/night variation in the sea surface temperatures the daily time series will show a signal that varies with the 14-day tidal cycle. This artifact does not affect the monthly sea surface temperature 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.
