Replaced by new submission (44784) on 2025-12-16
please replace my earlier CTD submission with this - fixed a bug where the wrong column was used in determining header information.
Preliminary CTD data for A16N (Leg 2)
Data QC report for the inorganic carbon parameters, analogous to the document submitted for A16N Leg 1. The report can be put in the Supplemental Data and Documents section. DOI is https://doi.org/10.25923/437g-kd65
CTD data for A16N 2023 Legs 1 and 2 is expected to be submitted in Fall 2025.
Once complete, the bottle file for Leg 2 will be updated and processed accordingly.
The original file will also be reviewed for sample number alignment,
and any updates will be merged in.
Update to the carbon data that was previously submitted on 5/16/24. Specific changes: fCO2 870119 value change (537.58, was 537.99) 880107 flag change (6, was 2) 1030212 value change (659.43, was 659.85) DIC 810116 value and flag change (2193.52 flag 6, was 2201.2 flag 2) 840114 value change (2206.35, was 2205.66) 850115 flag change (6, was 2) 920301 flag change (6, was 2) 970124 flag change (6, was 2) 1010124 flag change (6, was 2) 1030224 flag change (6, was 2) 1180113 flag change (6, was 2) no changes for pH or TA data
Nutrient data corrected for duplicate station submitted by Eric Wisegarver via email.
A16N Leg 2 (2023) data for CFCs, note still preliminary - only QC flags 2, 6, and 9 applied
We have updated the δ13C-DIC data from Prof. Wei-Jun Cai's group and made some changes to the quality flags.
