WHOI products:
N Atlantic T-He in 1981
T-He age
2. MICOM model year 100 (60 years dynamical model spin-up and 40 years for the Age tracer, Tritium&Helium)
Tritium&Helium are set to zero at year 60 and a source of Tritium is set in the mixed layer for the first 3 years,
corresponding to the bomb related peak in 1965-67. Only
the radioactive decay product of tritium, the tritiugenic helium-3 has been modelled.
