      Key Points

      • Observational uncertainties in coral isotope measurements are manageable
      • Linear SST/SSS to delta 18O conversions yield inaccurate ENSO amplitudes
      • Climate/delta 18O conversions can be improved by including seasonal influences

      Key Points

      • A decrease in net org. carbon burial drove carbon cycle changes during the LPEE
      • An increase in volcanic activity might have also contributed to the changes
      • A drop in net org. C burial may represent incr. oxid. of peat or gas hydrates

      • Changes in the organic matter reflect millennial-scale changes in productivity
      • Sudden flush of material at the onset of deglaciation

      Key Points

      • Novel Earth system modeling to recover true carbon isotope excursion sizes
      • Estimates for event size increase values for rate and magnitude of carbon input

      Key Points

      • The interglacial is dominated by enhanced remineralization and deep-ocean supply
      • The glacial decrease arises from upper ocean net primary production
      • The state transients follow patterns analogous to living beings
