We
present 16 months of semi-continuous Ar/N2 data measured at the
Scripps Pier in La Jolla, CA.
The concentration of atmospheric Ar/N2 depends on air-sea
heat flux. As the ocean takes up heat,
both argon and nitrogen are degassed to the atmosphere; as the ocean cools,
they are taken up. This record is the
beginning of a long-term monitoring program that will parallel the O2/N2
and CO2 measurement programs
at Scripps and may help resolve the oceanic contribution to atmospheric CO2 variability.
