GLODAPv2.0 known issues This document, initialized Nov 17 2015 summaries known issues in the GLODAPv2 data product files. It is updated as new issues are discovered and reported. The issues will be resolved in future versions of the data product files. last update: 18 Jan 2016, Are Olsen CRUISE SPECIFIC ISSUES 35TH20040604 Updated PO4 data received from PI. Will be included in future version. Updated data may already be downloaded from the annotations section of this cruise in the GLODAPv2 adjustment table at https://glodapv2.geomar.de/adjustments/show/35TH20040604 06MT19960910 measured pH not included in product file, should have been, these are NBS data that have passed QC 06MT20060606 He, He3 and Ne data exist, but are not included in product or original data file.

Instead the v2.0 product files include calculated pH whenever data for TAlk and TCO2 pairs are available. The measured pH data from the cruise are available in the original data file accessible through the GLODAPv2 CST at CDIAC. 316N19720718.1 This is the multi-leg GEOSECS Atlantic cruise. Its EXPOCODE is 316N19720718 and not 316N19720718.1 as given in the product files. This is an ad hoc designation of the first leg of GEOSECS Atlantic. This will be revised in future versions. 316N19871123.1 This is the multi-leg SAVE cruise. Its EXPOCODE is 316N19871123 and not 316N19871123.1 as given in the product files. This is an ad hoc designation of the first leg of SAVE. This will be revised in future versions. 316N19970717 measured pH not included in product file, should have been, have passed QC 316N19970815 measured pH not included in product file, should have been, have passed QC 318M20091121 P06.2009 Issues with tritium data, corrected values have been received from PI and included in the original data file in the CST, but data in product have not been updated 325020060213 P16N.2006 Issues with tritium data, corrected values have been received from PI and included in the original data file in the CST, but data in product have not been updated 320620110219 S04P.2011 Issues with tritium data, corrected values will be received from PI 33LG20090916 CLIVAR_A21_2009, LMG200909 Salinity data have been unjustly excluded from GLODAPv2 product. In hindsight, bottle salinity values are indeed of insufficient quality (strong offets between stations, but CTDsal values are good and accurate. Next version will re-include CTDsal. In meantime, users are advised to use CTDsal values from original dataset at http://cdiac.ornl.gov/ftp/oceans/CLIVAR/A21_33LG20090916 33LK19960415 measured pH not included in product file, should have been, have passed QC 33MW19930704.1 This is the two-leg 33MW19930704. Its EXPOCODE should be 33MW19930704 and not 33MW19930704.1 as given in the product. This will be revised in future versions. 33RO20071215 P18.2007 Issues with tritium data, corrected values will be received from PI 33RR20080204 I6S.2008 Issues with tritium data, corrected values will be received from PI 35A820050607 He, He3 and Ne data exist, but are not included in product original data file.

These should receive a corresponding adjustment down in future versions. 49HO19970602 measured pH not included in product file, should have been, have passed QC 49HO19970711 measured pH not included in product file, should have been, have passed QC 49HO20000601 measured pH not included in product file, should have been, have passed QC 49HO20000621 measured pH not included in product file, should have been, have passed QC 49NZ19971111 measured pH not included in product file, should have been, have passed QC 49NZ19981030 measured pH not included in product file, should have been, have passed QC 49NZ19991120 measured pH not included in product file, should have been, have passed QC 49NZ20001227 measured pH not included in product file, should have been, have passed QC 49NZ20031106 measured pH not included in product file, should have been, have passed QC 49NZ20041117 measured pH not included in product file, should have been, have passed QC 58JH19951108 Oxygen data from station 327 are biased low. These should not be used and will be removed in future versions of GLODAP. 67SL19881117 measured pH not included in product file, should have been, have passed QC 74AB19910501 measured pH not included in product file, should have been, have passed QC 74DI19900612 measured pH not included in product file, should have been, have passed QC 74DI19970807 measured pH not included in product file, should have been, have passed QC 90MS19811009 measured pH not included in product file, should have been, have passed QC GENERAL ISSUES Secondary QC flags for calculated CO2 chemistry data The secondary QC flags for calculated CO2 chemistry data have not been assigned as intended (see item 11 in section 5.2 of Olsen et al., ESSD 2015). These will be revised in future versions. PRESSURE/DEPTH 99 records have pressure and depth that are more than 5% AND 10% different. The causes are not clear, but this will be adressed in future versions. A complete table of these records are available at the end of this document.
