Item #d93mar71

"Coral Reefs: Sources or Sinks of Atmospheric CO2," J.R. Ware (Dept. Oceanog., Univ. Hawaii, Honolulu HI 96822), S.V. Smith, M.L. Reakakudla, Coral Reefs, 11(3), 127-130, Sep. 1992.

Although it has frequently been thought that coral reefs function as sinks of atmospheric CO2, the precipitation of calcium is accompanied by a shift of pH that results in the release of CO2. Estimates that the CO2 released by reefs amounts to 0.4-1.4% of the current anthropogenic production due to fossil fuel combustion.

Item #d93mar72

"Return of the Coral Reef Hypothesis: Basin to Shelf Partitioning of CaCO3 and Its Effect on Atmospheric CO2," B.N. Opdyke (Dept. Geol. Sci., Univ. Michigan, Ann Arbor MI 48109), J.C.G. Walker, Geology, 20(8), 733-736, Aug. 1992.

Differences in the rate of coral reef carbonate deposition from the Pleistocene to the Holocene may account for the recently recognized Quaternary fluctuations in CO2. A simple numerical model of the global carbon cycle replicates the 80 ppm atmospheric CO2 fluctuations observed in the Vostok ice core for the Quaternary, as well as approximate depth changes in percent carbonate of sediments measured in the Pacific ocean over the same time interval.
