String summary "This glider deployment is part of continuing Investigation of Mid-Atlantic Cold Pool Dynamics: The Ocean Glider Component. The program goal is to measure the seasonal-varying 1km-100km features of the Mid-Atlantic Cold Pool in order to validate regional and global numerical ocean models and to investigate the Cold Pool's role in modulating hurricane intensity. The glider is equipped with a CTD, a WETLabs Scientific 3-channel puck to measure chlorophyll a, backscatter (700nm), and CDOM and an Aanderaa 3830 oxygen optode. The glider is planned sample along a triangle in the Southern New England Bight region south of Martha’s Vineyard two times over approximately 40 days. Delayed mode dataset.";

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.
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.
