  • Processing error corrected, revised data available by ftp Mary Johnson

    Date: 2001-06-20
    Data Type: CTD
    Action: Data Update:
    Note:
    ODF has discovered a small error in the algorithm used to convert ITS90 temperature calibration data to IPTS68.  This error affects reported Mark III CTD temperature data for most cruises that occurred in 1992-1999.  A complete list of affected data sets appears below.
    
    ODF temperature calibrations are reported on the ITS90 temperature scale.  ODF internally maintains these calibrations for CTD data processing on the IPTS68 scale.  The error involved converting ITS90 calibrations to IPTS68.  The amount of error is close to linear with temperature: approximately -0.00024 degC/degC, with a -0.00036 degC offset at 0 degC.  Previously reported data were low by 0.00756 degC at 30 degC, decreasing to 0.00036 degC low at 0 degC.  Data reported as ITS90 were also affected by a similar amount.  CTD conductivity calibrations have been recalculated to account for the temperature change.  Reported CTD salinity and oxygen data were not significantly affected.
    
    Revised final data sets have been prepared and will be available soon from ODF (ftp://odf.ucsd.edu/pub/HydroData).  The data will eventually be updated on the whpo.ucsd.edu website as well.
    
    IPTS68 temperatures are reported for PCM11 and Antarktis X/5, as originally submitted to their chief scientists.  ITS90 temperatures are reported for all other cruises.
    _______________________________________________________________________
    Changes in the final data vs. previous release (other than temperature and negligible differences in salinity/oxygen):
    
    S04P:	694/03 CTD data were not reported, but CTD values were reported with the bottle data.  No conductivity correction was applied to these values in the original .sea file.  This release uses the same conductivity correction as the two nearest casts to correct salinity.
    
    AO94:	Eight CTD casts were fit for ctdoxy (previously uncalibrated) and resubmitted to the P.I. since the original release.  The WHP-format bottle file was not regenerated.  The CTDOXY for the following stations should be significantly different than the original .sea file values:
    	  009/01  013/02  017/01  018/01  026/04  033/01  036/01  036/02
    
    I09N:	The 243/01 original CTD data file was not rewritten after updating the ctdoxy fit.  This release uses the correct ctdoxy data for the .ctd file.  The original .sea file was written after the update occurred, so the ctdoxy values reported with bottle data should be minimally different.
