String summary "This dataset encompasses 145 seawater samples collected from 23 hydrographic stations during the AL510 cruise in the Baltic Sea aboard the research vessel Alkor, from June 6 to June 11, 2018. Helium isotopes and neon measurements were conducted in the Noble Gas Laboratory of the Lamont-Doherty Earth Observatory on a dedicated, fully automated VG5400 mass spectrometer following the procedures described by Ludin et al. (1998). Helium and neon samples were collected from Niskin bottles in copper tubes (40 ml) sealed by stainless steel pinch-off clamps. Shipboard sampling, gas extraction, and isotopic analysis were done by Tobias (Toby) Koffman with data processing by Peter Schlosser.";

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.
