At present it is not always easy to find instrument S/Ns. We are working on improving this in the OOI Data Explorer. But we do not yet have Southern Ocean glider data in the Data Explorer.
So the best/easiest way to find instrument S/Ns is to look in our asset management GitHub repository.
Under asset-management/deployment at master · oceanobservatories/asset-management · GitHub you will find a CSV file for each platform listed. The Global Southern Ocean Gliders all begin with GS05MOAS and then have either GL or PG followed by the Glider S/N (only 8 were deployed there):
Only the Profiling Gliders (PG) have the nitrate sensor.
In each Deploy CSV you will find a line for each component or sensor which transmits data listed by Reference Designator. The instrument S/Ns are found in the sensor.uid column in this format: CGINS-DOSTAM-00324 where CGINS defines it as an instrument, DOSTAM is the OOI Instrument Class and Series (DOSTA-M), and 00324 is the instrument Serial number (padded with zeros to a 5-digit number, or truncated if the S/N is longer than 5 digits).
Each CSV has data for all of the deployments of that platform. For gliders there is often only one deployment per CSV, but for moorings there are multiple deployments in each CSV. So be sure to check the deploymentNumber , startDateTime , and stopDateTime columns to be sure you are in the deployment that you want.
It may be a little tricky at first, but once you are used to the terminology and format, it will get easier. Please let me know if you have further questions.
We will be working on making this information more easily accessible in the future.
Thanks and stay safe,
