"CTD,20260310CCHSIOWB
Submitted file had FLAG_I, the values were consistent with IGOSS flags.
IGOSS flags were mapped to WOCE CTD flags: 0 mapped to 5 for missing/-999 values, 1 mapped to 2.
Changed FLAG_I to FLAG_W, CTDTMP2 to CTDTMP_ALT_1, CTDSAL2 to CTDSAL_ALT_1, and CTDOXY2 to CTDOXY_ALT_1.
Removed the upcast data at 3449.0 dbar from station 167.
At stations 48, 56, 91, 135, 190, 205, 208, 211, 214, 221, 222, 228, 237, 250, 255, 281, 292, large offsets between CTDOXY and CTDOXY_ALT_1 were observed in the absence of bottle oxygen data; therefore, both CTD oxygen sensors were flagged 1 (uncalibrated).
At station 9, a large offset between CTDOXY and CTDOXY_ALT_1 was observed. The bottle oxygen data at this station are questionable (flagged 3) for reference, both CTD oxygen sensors were flagged 1.
At all other stations, significant inter-sensor offsets were observed. Comparison with bottle oxygen data indicates that CTDOXY is more consistent with the bottle measurements, whereas CTDOXY_ALT_1 appears uncalibrated and was flagged 1.

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.
