- Ocean-atmosphere interaction—Congresses
The impacts on ocean chemistry of a variety of scenarios capable of producing the 90×10−6 atmosphere glacial to interglacial increase in CO2 are explored. It is shown that each scenario produces a unique combination of 13C, Cd, O2 and CaCO3 dissolution responses. Thus, once we have reliable ocean wide records of these parameters, it should be possible to greatly reduce the list of those scenarios capable of explaining this CO2 change. If our present information regarding these records is correct, then the only acceptable hypotheses are 1) shelf deposition, 2) Redfield ratio change plus forest growth or 3) phosphorite deposition plus forest growth. When global cadmium records become available further cuts will be possible.
