GEOLOGICAL NOTES Quaternary Glacial-Interglacial Climate Cycles in Hawaii

The upper kilometer of the Hawaiian Scientific Drilling Program core consists of lavas that were emplaced subaerially, burying paleosols. These paleosols were preserved with minimal alteration and are used to construct a ∼330-kyr Quaternary climate record. Within the temporal resolution of this record, there appears to be a ∼100-kyr climate oscillation between cool-dry and warm-wet conditions, ...

Role of marine biology in glacial-interglacial CO2 cycles.

It has been hypothesized that changes in the marine biological pump caused a major portion of the glacial reduction of atmospheric carbon dioxide by 80 to 100 parts per million through increased iron fertilization of marine plankton, increased ocean nutrient content or utilization, or shifts in dominant plankton types. We analyze sedimentary records of marine productivity at the peak and the mi...

Glacial-Interglacial Atmospheric CO2 Change —The Glacial Burial Hypothesis

Organic carbon buried under the great ice sheets of the Northern Hemisphere is suggested to be the missing link in the atmospheric CO2 change over the glacial-interglacial cycles. At glaciation, the advancement of continental ice sheets buries vegetation and soil carbon accumulated during warmer periods. At deglaciation, this burial carbon is released back into the atmosphere. In a simulation o...
