DO profiles were used in conjunction with oxygen bottle measurements (Winklers) to produce a post-cruise oxygen-calibrated CTD product for scientific use as part of Gases in the Overturning and Horizontal circulation of the Subpolar North Atlantic Program (GOHSNAP), which has added moored oxygen sensors to the OSNAP mooring array, beginning in 2020. This documentation contains overviews of CTD data collection and processing and of the oxygen sensor calibration method. For each cruise, we provide a summary of relevant cruise events, oxygen sensor calibration results, and issues/problems associated with oxygen data collected.\n\ncdm_data_type = Other\nVARIABLES:\nCruise (unitless)\nStation (unitless)\nDown_Up (unitless)\nDate_UTC (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nCTDPRES (dbar)\nCTDTEMP_ITS90 (degrees Celsius)\nCTDTEMP_flag (unitless)\nCTDSAL_PSS78 (unitless)\nCTDSAL_flag (unitless)\nCTDOXYCUR (volts)\nCTDOXYCUR_flag (unitless)\nCTDOXY (umol/kg)\nCTDOXY_flag (unitless)\nfile_name (unitless)\n https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_933743_v1_fgdc.xml https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_933743_v1_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_933743_v1/index.htmlTable https://www.bco-dmo.org/dataset/933743 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_933743_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_933743_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_933743_v1

Measurements of dissolved inorganic carbon and pH on the total scale were also made as quality control checks. GLODAPv2 hinted at a potential offset between laboratories in the Pacific Ocean. We hypothesized that if non-negligible amounts of organic alkalinity were present, the different methods could be titrating different amounts leading to differences between the methods. The results show that any offset is within the uncertainty of the analytical precision and presence of organic alkalinity in open ocean waters remains inconclusive.\n\ncdm_data_type = Other\nVARIABLES:\nCruise (unitless)\nsample_ID (unitless)\nStation (unitless)\nCast (unitless)\nNiskinBottle_No (unitless)\nDate (unitless)\ntime_unitless (Time, unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\nCTD_Salinity (unitless)\nCTD_Salinity_flag (unitless)\nBottle_Salinity (unitless)\nBot_Sal_flag (unitless)\nCTD_Pressure (decibars (db))\nTotal_Alkalinity_Single_Step_method (micromoles per kilogram of seawater (umol/kg_sw))\nTotal_Alkalinity_Single_Step_Method_flag (unitless)\nFinal_pHt_for_Single_Step_method_TA (total scale)\nTotal_Alkalinity_Open_Cell_Method (micromoles per kilogram of seawater (umol/kg_sw))\n...
