From: Maribel García-Ibáñez Date: Wed, Mar 30, 2022 at 10:58 AM Subject: [CARIMED] - Update of NCEI cruise metadata and files for 31GI19760901 To: Alex Kozyr - NOAA Affiliate Cc: Marta Álvarez Hi Alex, Regarding NCEI cruise metadata and files for cruise 31GI19760901, here are the actions to be made on the NCEI website: Changes for data files on the NCEI file repository for 31GI19760901: It should include the files contained in the Google Drive folder for the cruise: https://drive.google.com/drive/folders/14FQjFJxIZIQy0KHGg2elOSb1k-pgrrxl Reupload the data file (file: 31GI19760901_hy1.csv). Upload the map (file: map_cruise_31GI19760901.tif). Remove the .mat file (31GI19760901_INI.mat) from the NCEI repository. Remove the README file (README_31GI19760901.txt) from the NCEI repository. Changes for metadata information on NCEI for 31GI19760901: The INVESTIGATORS and Principal Investigators should be Frank J. Millero - Rosenstiel School of Marine and Atmospheric Science (RSMAS). "VARIABLES/PARAMETERS" fields: For Total alkalinity: Update field:"Detailed sampling and analyzing information:" with "Potentiometric method developed by Edmond (DSR, 1970). Classic titration with 0.1 m HCl at 25±0.01ºC. The emf measurements were made with an Orion or Leeds and Northrup pH meter and combination glass electrode. Precision was 0.003 meq kg-1 and the accuracies were thought to be 0.01 meq kg-1.". Update field: "Researcher name:" with "F. Millero (University of Miami)". Remove field "Researcher institution: RSMAS, USA". For pH on total scale at measured T 25ºC: Update field:"Detailed sampling and analyzing information:" with "NBS scale at 25ºC, potentiometric method, the combination glass electrode (Corning) and pH meter (Leeds and Northrup) were calibrated before and after each series of measurements with NBS buffers (pH 4.0, 7.0 and 9.0). The precision of pH was 0.003 units and accuracy was thought to be 0.02 units.". Update field: "Researcher name:" with "F. Millero (University of Miami)". Remove field "Researcher institution: RSMAS, USA". Best regards, Maribel I.
