Daily variability of dissolved inorganic radiocarbon at three sites in the surface ocean
We report radiocarbon measurements of dissolved inorganic carbon (DIC) in surface water samples collected daily during cruises to the central North Pacific, the Sargasso Sea and the Southern Ocean. The ranges of Δ14C measurements for each cruise (11-30‰) were larger than the total uncertainty (7.8‰,...
