String comment "pH, TA, and DIC measurements from discrete water samples taken at glider deployments and recoveries. Water samples were collected at multiple depths via Niskin bottles mounted on a CTD-rosette, or via individual Niskin bottle casts. pH (on the Total pH scale) of water samples was measured spectrophotometrically at 25°C with purified meta-cresol purple (mCP, Liu et al. 2011) using 10 cm pathlength cylindrical glass cells and an Agilent Technologies Cary 8454 UV-Vis spectrometer. pH was calculated according to the equations presented in Douglas and Byrne (2017). Total alkalinity (TA) titrations for water samples were performed by a custom-built titration apparatus, following the approach of Standard Operating Procedure 3b (Dickson et al. 2007). These values have not been corrected for temperature, pressure, or salinity.";

String summary "For each project, underwater Slocum gliders were deployed with an integrated Conductivity, Temperature, Depth (CTD) and deep rated version of the Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor as well as other sensors. Water samples were taken during deployment and recovery to ground-truth the glider-based pH sensor. Full-resolution quality-controlled glider datasets can be downloaded via the National Centers for Environmental Information (NCEI) Ocean Carbon and Acidification Data System (https://www.ncei.noaa.gov/products/ocean-carbon-acidification-data-system). Full-resolution raw glider datasets with associated QC variables can be downloaded at https://slocum-data.marine.rutgers.edu/erddap/index.html.";

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.
