String summary "During the first several months of the Surface Water and Ocean Topography (SWOT) satellite mission, the satellite was in an orbit that passed over select locations twice per day (one ascending and one descending pass). One of these 'cross-overs' was located offshore of Cape Hatteras, NC where the Gulf Stream detaches from the continetal margin. In support of the calibration and validation of the SWOT measurements of sea surface topography, Spray gliders sampled within this cross-over as part of the SWOT Adopt-A-Crossover - MAB-SWOT campaign (https://www.swot-adac.org/campaigns/mab-swot/) in 2023. Gliders primarily attempted to hold station at the center of a triangular array of CPIEs just north of the Gulf Stream. Additional plots of these data are available at https://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.
