From: Maribel García-Ibáñez Date: Thu, Mar 24, 2022 at 11:56 AM Subject: [CARIMED] - Update of NCEI cruise metadata and files for 06MT20110405 To: Alex Kozyr - NOAA Affiliate Cc: Marta Álvarez Hi Alex, Regarding NCEI cruise metadata and files for cruise 06MT20110405, here are the actions to be made on the NCEI website: Changes for data files on NCEI for cruise 06MT20110405: Reupload the csv file. You can find the updated csv file here: https://drive.google.com/drive/folders/1G97a6PiaQWOprtCNhAOgIMdd6dOCmS8i Upload the map to the NCEI file repository for the cruise. The map is also here: https://drive.google.com/drive/folders/1G97a6PiaQWOprtCNhAOgIMdd6dOCmS8i This cruise was already in NCEI repository before CARIMED. Therefore it has extra files in NCEI repository. Could we only leave the CSV file (to be reupload), the map (to be upload), and the cruise report (already in the folder. File M84_3.pdf), and maybe move the other files inside a folder of "extra files"? This way, the possible CARIMED user will have a similar repository for each CARIMED cruise. The old files in NCEI have Barium, DELTA CARBON-13, and DELTA CARBON-14 data that is not included in the CARIMED files. What do we do about it, Alex? Metadata information to be updated on NCEI for cruise 06MT20011018: The INVESTIGATORS and Principal Investigators should only be Toste Tanhua - GEOMAR Helmholtz Centre for Ocean Research Kiel (GEOMAR). For the "VARIABLES/PARAMETERS" fields to be coherent with all the cruises, I would suggest changing the variable names for 06MT20110405 as they are for 06M220180302, i.e.: For Dissolved Inorganic Carbon: The abbreviation should be TCARBN. Add the field "Sampling instrument: Niskin Bottles". Update the information from the field "Standardization description" to: "The precision was controlled by titration of several bottles filled from the same Niskin bottles at two different locations. From these results, it can be concluded that precision is ±0.6 μmol kg−1 or better. The accuracy was checked by running a total of 42 bottles of certified reference material (CRM, batch 108). Standards were run occasionally (18 times) in duplicate from the same bottle (if the first value differed by more than 1 μmol kg−1 from the certified value). However, only the first result was taken, since it cannot be excluded, that the bottle was affected by contact with lab air between first and second measurement. The second only had the purpose to flag the bottle questionable, should the second measurement deviate by more than 1 μmol kg−1 from the first measurement (this was not the case).The certified value is given with a standard deviation of ± 0.7 μmol kg−1. The precision of the analysis was ± 0.6 μmol kg−1 and the accuracy was determined to be ±2.5 μmol kg−1.". Add the field "Researcher name: L. Mintrop (MARIANDA), M. Álvarez (IEO)" This parameter should appear where the parameter TCARBN appears (after the nutrients), and the information contained in the parameter TCARBN that appears later in the list should be merged with the information of Dissolved Inorganic Carbon, so we only have one TCARBN parameter. For Total alkalinity: The abbreviation should be ALKALI. Add the field "Sampling instrument: Niskin Bottles". Add the field "Detailed sampling and analyzing information: Samples for alkalinity determination were collected in 600mL borosilicate bottles and were analysed within one day after sampling. Samples were analysed following the double end point potentiometric technique by Pérez and Fraga (Mar. Chem., 1987) and Pérez et al. (CC.MM., 2000). Measurements of CRM were performed in order to control the accuracy of the alkalinity measurements; the pH as measured by the electrode was corrected to obtain the closest mean alkalinity to the CRM; the pH correction was never larger than 0.05. The precision of the alkalinity measurements was better than ±0.6 μmol kg−1 determined from duplicate Niskin bottles, and the accuracy of the alkalinity measurements (i.e. including sampling errors) is determined to be 1 μmol kg−1 . Additionally, the daily drift of the system was determined by regular measurements of a substandard (surface seawater); this drift was always very low. The precision of the analysis was ± 0.6 µmol/kg and the accuracy was determined to be 1 µmol/kg .". Add the field "Researcher name: M. Álvarez (IEO)" This parameter should appear where the parameter ALKALI appears (after the TCARBN), and the information contained in the parameter ALKALI that appears later in the list should be merged with the information of Total alkalinity, so we only have one ALKALI parameter. For pH: The name of the variable should be changed to pH on total scale measured at 25ºC. The abbreviation should be PHTS25P0 The informtation in field "Detailed sampling and analyzing information:" should be: "pH was measured in cylindrical optical glass 10-cm pathlength cells with a spectrophotometric procedure (Clayton and Byrne, DSR I, 1993). pH is reported in the total scale at 25 ºC (pHST25). The precision was estimated to ±0.0012 by measuring replicates from the same Niskin bottle. Regarding the accuracy, the theoretical pH25T value for the 108 CRM batch using the dissociation constants from Mehrbach et al. (LO, 1973) refitted by Dickson and Millero (DSR, 1987) is 7.8782. Replicate pH measurements along the cruise on CRMs are lower than the theoretical value by 0.0962±0.0012 pH units. An internal consistency analysis showed that this correction should not be applied.". Add the field "Researcher name: M. Álvarez (IEO)" This parameter should appear where the parameter PH_TOT appears (after the ALKALI), and the parameters PH_TOT and PH_TMP should be removed from the list. For CTDTMP: Controlled vocabulary name should be CTD WATER TEMPERATURE. Add the field "Researcher name: D. Hainbucher (ZMAW), V. Cardin (OGS)" For CTDSAL: Controlled vocabulary name should be CTD SALINITY. Add the field "Researcher name: D. Hainbucher (ZMAW), V. Cardin (OGS)" For CTDOXY: The name of the variable should be changed to CTD Oxygen (abbreviation should still be CTDOXY). Controlled vocabulary name should be CTD oxygen. Add the field "Observation type: CTD". Add the field "Researcher name: D. Hainbucher (ZMAW), V. Cardin (OGS)" For OXYGEN: The name of the variable should be changed to Dissolved Oxygen The abbreviation should be OXYGEN (there is a typo and it appears as OXUGEN). Add the field "Observation type: Bottle discrete". Add the field "Researcher name: M. Álvarez (IEO)" For SILCAT: The name of the variable should be changed to Silicate (abbreviation should still be SILCAT). Add the field "Observation type: Bottle discrete". Add the field "Researcher name: T. Tanhua (GEOMAR), G. Civitarese (OGS)" For NITRAT: The name of the variable should be changed to Nitrate (abbreviation should still be NITRAT). Add the field "Observation type: Bottle discrete". Add the field "Researcher name: T. Tanhua (GEOMAR), G. Civitarese (OGS)" For NITRIT: The name of the variable should be changed to Nitrite (abbreviation should still be NITRIT). Add the field "Observation type: Bottle discrete". Add the field "Researcher name: T. Tanhua (GEOMAR), G. Civitarese (OGS)" For PHSPHT: The name of the variable should be changed to Phosphate (abbreviation should still be PHSPHT). Add the field "Observation type: Bottle discrete". Add the field "Researcher name: T. Tanhua (GEOMAR), G. Civitarese (OGS)" For CFC-12: The name of the variable should be changed to Chlorofluorocarbon 12 (abbreviation should still be CFC-12). Add tshe field "Observation type: Bottle discrete". Add the field "Researcher name: T. Tanhua (GEOMAR)" For SF6 The name of the variable should be changed to sulfur hexaflouride (abbreviation should still be SF6). Add thefield "Observation type: Bottle discrete". Add the field "Researcher name: T. Tanhua (GEOMAR)" Add the field "Researcher name:" to the following parameters and fill it with the following information: HELIUM: T. Tanhua (GEOMAR) TRITIUM: T. Tanhua (GEOMAR) NEON: T. Tanhua (GEOMAR) The "PUBLICATIONS DESCRIBING THIS DATASET" field in NCEI metadata should contain: Tanhua T. (2013).
