The cycle can be divided into several compartments: gas ex- change through the sea surface as controlled by Henry's Law; the dissolved inorganic components as controlled by the chemical equilibrium of the carbon dioxide system, including the carbonate minerals; photosynthesis or primary production, the major mechanism for carbon dioxide transfer from the in- organic to the organic carbon compartment as con- trolled by physiological requirements of plants and the chemical and physical structure of the water column; respiration, which returns organic carbon consumed by marine biota to the inorganic system as CO2, as controlled by biological energy transfer processes; formation of detritus as derived from the excess of primary production over consumption, fecal pellets, and animal remains (much of this detritus settles to the bottom as the organic component of particulate matter and provides food for the benthic biomass or enters into other sedimentary processes); and, finally, the alkaline earth carbonate secretions and precipitates which may form long-term deposits of carbon dependent upon solubility equilibrium rela- tionships for recycling to the inorganic pool. Since until now I have had only two opportunities to make carbon dioxide measurements in this region- one in May 1976 and one in June and July of 1978— the results reported here are preliminary in nature. And yet these observations have revealed some facts and raised some questions that should be reported now. For 1980 and subsequent seasons, more defini- tive and extensive studies are planned which it is hoped will permit a more rigorous evaluation of the
