Coastal upwelling and atmospheric CO2 changes
Listed in PANGAEA
A transfer function relating diatom assemblages in surface sediments and primary production in the photic zone was used to calculate variations in primary production in hole ODP Leg 112, Site 681A over the last 400 kyr.
Description
Primary production off central Peru was enhanced during peak glaciations and it decreased during peak interglacials, but low and high production periods also occurred in both glacials and interglacials.
The close resemblance of the primary production curve off Peru to the atmospheric CO2 Vostok record suggests a relationship between the Peruvian neritic biological pump and atmospheric pCO2.
