String summary
"California Underwater Glider Network - Line 56. The overarching goal of the California Underwater Glider Network is to sustain baseline observations of climate variability off the coast of California. The technical approach is to deploy autonomous underwater gliders in a network to provide real-time data.
The CUGN uses Spray underwater gliders making repeated dives from the surface to 500 m and back, repeating the cycle every 3 hours, and traveling 3 km in the horizontal during that time. The CUGN includes gliders on three of the traditional cross-shore California Cooperative Oceanic Fisheries Investigations (CalCOFI) lines: line 66.7 off Monterey Bay, line 80 off Point Conception, and line 90 off Dana Point.
The glider missions typically last about 100 days, and cover over 2000 km, thus providing 4-6 sections on lines extending 300-500 km offshore. Since 2005 the CUGN has covered 200,000 km over ground in 28 glider-years, while doing 90,000 dives.";

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
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.
- (easy) You can get data by using the dataset's Data Access Form or Subset form. They make the URL for you.
- (easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
- (not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.
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.
