Role of oceanic iron biogeochemistry in atmospheric CO2 variability between the last glacial maximum and the holocene
During the last glacial cycle, atmospheric CO2 varied by about 80–100 ppmv between glacial and interglacial periods. A substantial fraction of this change is thought to reflect variations in the strength of the marine biological pump, driven in part by changes in iron (Fe) supply from mineral dust to highnutrient, low-...
