Abstract

We describe the use of the ¹⁴C-AMS technique to study the influence of upwelling waters to the local biological production, at Arraial do Cabo, Brazil. Results on Δ¹⁴C from seaweed tissues incubated into three different types of water mass show the association of primary production with the upwelling waters. We also discuss the importance of high- precision ¹⁴C - AMS measurements for this kind of study, and the properly application of isotopic fractionation corrections on radiocarbon results.
