| Summary: | This dataset is a Del13C-DIC dataset 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 dataset 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 dataset 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 ... |
