Collaborative Research: Advanced calibration of a carbonate ion proxy — NSF Award to Columbia University (NY, $284,622)
Evidence from ice cores in Antarctica has shown that the carbon dioxide (CO2) content of the atmosphere has changed systematically with Earth’s climate over the last 800,000 years, with lower atmospheric CO2 concentrations in cold (glacial) intervals. Because the oceans must maintain a balance between alkalinity suppli

| Abstract | Evidence from ice cores in Antarctica has shown that the carbon dioxide (CO2) content of the atmosphere has changed systematically with Earth’s climate over the last 800,000 years, with lower atmospheric CO2 concentrations in cold (glacial) intervals. Because the oceans must maintain a balance between alkalinity supplied by continental weathering, and alkalinity removed by calcium carbonate burial, at least over long time periods, a reduction in the burial of calcium carbonate on continental she |
