Extended Data Fig. 5

(a) sampling stations. (b-d) water age based on CFC-11 at 300 m, 500 m, and 800 m, respectively. The dataset is built upon the GLODAPv2 and can be assessed from “Water mass ages based on GLODAPv2 data product” (NCEI Accession 0226793 at National Centers for Environmental Information). Note that the water ages are estimated using tracer CFC-11, which assumes no mixing and is simply derived by matching the observed tracer concentration to the atmospheric history. The colorbar scale is limited to 60 years, so it may restrict the display of some water ages exceeding 60 years. This figure is created by Ocean Data View at https://odv.awi.de/.
