Ar-39 & C-14 data JOIS 2022 (Canadian Arctic Ocean)

Résumé fourni par la source

Argon-39 and Carbon-14 data (3 depth profiles) collected in the Canada Basin of the Arctic Ocean during the JOIS/BGOS expdition from 15 September to 13 October 2022 (JOIS 2022) onboard CCGS Louis S. St-Laurent. C14: Expressed in F14C (fraction modern 14C) and Delta14C. Corresponding 1sigma uncertainties are derived from repeated measurements of an internal standard. Ar39: Expressed in pmAr (percent modern Argon). The unit refers to the concentration measured in the sample relative to modern atmospheric levels (100pmAr). Upper and lower bounds (corresponding to +1sigma and -1sigma) are derived from the upper and lower bounds of the asymmetric PDF of abundance. Metadata and hydrographic data are taken from https://www2.whoi.edu/site/beaufortgyre/data/ctd-and-geochemistry/.
