The program called Geochemical Ocean Section Study (GEOSECS) was initiated in 1971 and designed to make an oceanic inventory of chemical constituents in the world oceans, partly as a baseline study for future chemical changes, and partly to investigate large-scale oceanic transport and mixing processes. Measured were hydrographic parameters (salinity, temperature, and oxygen vs depth), the carbonate system, the nutrients, and assorted other constituents with heavy emphasis laid on the radioactive substances, radiocarbon, tritium, and radon.
Stuiver et al. (Tue,) studied this question.
