"CTD,20250819CCHSIOENA
CTD data were reprocessed by ODF. Newest submission from June 2024 completely replaces original submission.
Print precision set to CCHDO defaults
The following were notes included with the reprocessed data:
Issue:
A data user reported finding suspicious salinity data on several casts, with offset or erratic values observed at depths over 2000 meters. The issue was investigated and confirmed on six casts between stations 22 and 32. It was determined all three sensors on the primary CTD channel – conductivity, temperature and the SBE43 oxygen – were giving bad values, likewise affecting salinity which is derived from them. The oxygen sensor was replaced, for reasons documented previously, after cast 32. The issue was not detected in any subsequent data, suggesting a faulty SBE43 oxygen sensor as the likely cause of the reported issue.
Solution:
During data conversion from the original raw CTD data, the primary and secondary conductivity and temperature values for casts 13-32 have now been swapped, so that converted data appearing in the primary sensor columns for those casts are actually from the secondary sensors. It is these values which are used for subsequent fitting and are reported in the final data product. All CTD oxygen values reported in the final data product are derived from the Rinko oxygen sensor, which was not directly affected, but benefits from improved fitting.
During investigation of the issue, a second issue was discovered where the temperature fitting for BIO casts was found to be flawed. This issue is unrelated to the above issue, and all BIO casts for the entire cruise were affected. Conductivity and oxygen fitting were affected because of their dependence on post-fit temperature, though no flaws were otherwise identified in their respective fitting routines.
Temperature fitting routines were corrected and all BIO-cast data have been reprocessed.

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 (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

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.
