An Internally Consistent Dataset of Del13C-DIC Data in the North Atlantic Ocean (NCEI Accession 0164569)

browse graphicPreview graphic
NCEI accession 0164569 presents a Del13C-DIC data set for the North Atlantic, which has undergone strict quality control. The data, all in all 6569 samples, originate from oceanographic research cruises that took place between 1981 and 2014. During a primary quality control step based on simple range tests obviously bad data has been flagged. In a second quality control step systematic biases between of all cruises were quantified through a crossover analysis. The data set consists of 32 cruises of which 24 could be compared quantitatively for systematic biases through an adequate crossover study. Additive adjustments were applied to 11 of the 24 cruises. Based on this analysis the internal consistency of this data set is estimated to be 0.017 o/oo.

The NAC13v1.csv file contains the 13C data, a simple quality flag ('Del13Cf', 2: good, 9: bad/not measured) and a 2nd QC-flag ('Del13Cqc', 1: quality controlled, 0: not quality controlled). The NAC13v1_expocode.csv-File contains the allocation of the cruise numbers used in NAC13v1 and their EXPOCODEs as well as the respective cruise numbers in GLODAPv2 and CARINA. For this analysis some cruises that belong together were condensed to one, e.g. the TTO-NA cruises.
