String summary "The overarching goal of this project is to collect high resolution transects across the Gulf Stream. Though the speed of the Gulf Stream greatly exceeds the speed of a glider, gliders can be flown across the current as they are advected downstream. Missions prior to 2015 were conducted downstream (northeast) of Cape Hatteras, primarily between Cape Cod and Bermuda; missions since 2015 begin in Miami, FL and are planned to end on the New England continental shelf. During a typical 100-day mission between Miami and Cape Cod, a single glider completes 6-10 crossings of the Gulf Stream, returning approximately 800 profiles to the shallower of the sea floor or 1000 m. The current operational goal is to maintain at least one glider in the Gulf Stream at all times. Additional plots of these data are available at http://gliders.whoi.edu.";

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.
