The original cruise data (not adjusted) can be found in the PACIFICA Cruise Summary Table at http://cdiac.ornl.gov/oceans/PACIFICA/PACIFICA_table.html Best wishes, Alex. -- ******************************************* Alex Kozyr Carbon Dioxide Information Analysis Center Environmental Sciences Division Oak Ridge National Laboratory U.S. Department of Energy Building 2040, Mail Stop 6290 Oak Ridge, TN 37831-6290 U.S.A. tel 1-865-576-8449 fax 1-865-574-2232 Electronic address: kozyra@ornl.gov Ocean CO2 WWW Page: http://cdiac.ornl.gov/oceans/ ________________________________________ From: Liqing Affiliate > Date: Tuesday, August 13, 2013 1:40 PM To: Alexander Kozyr > Cc: Thomas Ryan - NOAA Federal >, "Hernan.Garcia@noaa.gov" > Subject: Question about the PACIFICA data product Hi Alex, I am currently working to archive the PACIFICA data product. Would you please help me with a question? In addition to the data product file, I also downloaded a csv copy of the "PACIFICA recommended adjustment table (1205)". We want this file to be archived together with the data product file, if it is an integral part of the data set. My question to you is how should people use this adjustment table? For example, if people see Expocode "18DD19920203", and Alkalinity of "-20.284" in the table, what should they do? They should add "-20.284" to all the Alkalinity data of that cruise (Expocode), to get the correctly quality controlled Alkalinity data? Or the values in the PACIFICA data product have already been offset by such adjustments, and the adjustments are just there to show people what the QC team did to the original data values? Thank you, Liqing
