The Corg peak is shown by radiocarbon dating to be temporally coincident with the last (Stage 2 or Wisconsin) glacial maximum. In contrast, CaCO3 profiles show less overall variation, which appears to be partly a function of the location of the sediments relative to the lysocline. Consideration of the iodine:Corg ratio in the sediments rules out enhanced preservation as a cause of the Stage 2 organic carbon enrichment. The peak, instead, must have resulted from a significant increase in productivity during the glacial maximum. This content is PDF only. Please click on the PDF icon to access.
