An internally consistent dataset of δ 13 C-DIC in the North Atlantic Ocean - NAC13v1
The stable carbon isotope composition of dissolved inorganic carbon (δ 13 C-DIC) can be used to quantify fluxes within the carbon system. For example, knowing the δ 13 C signature of the inorganic carbon pool can help in describing the amount of anthropogenic carbon in the water column. The measurem...

The stable carbon isotope composition of dissolved inorganic carbon (δ 13 C-DIC) can be used to quantify fluxes within the carbon system. For example, knowing the δ 13 C signature of the inorganic carbon pool can help in describing the amount of anthropogenic carbon in the water column. The measurements can also be used for evaluating modeled carbon fluxes, for making basin-wide estimates of anthropogenic carbon, and for studying seasonal and interannual variability or decadal trends in interior ocean biogeochemistry. For all these purposes, it is not only important to have a sufficient amount of data, but these data must also be internally consistent and of high quality. In this study, we present a δ 13 C-DIC dataset for the North Atlantic which has undergone secondary quality control. The data originate from oceanographic research cruises between 1981 and 2014.
