Upregulation of phytoplankton carbon concentrating mechanisms during low CO2 glacial periods and implications for the phytoplankton pCO2 proxy / Stoll, Heather (ETH Zürich) ; Guitián, José (ETH Zürich) ; Hernández Almeida, Iván (ETH Zürich) ; Mejía, Luz María (ETH Zürich) ; Phelps, Samuel (Lamont Doherty Earth Observatory) ; Polissar, Pratigya (Lamont Doherty Earth Observatory) ; Rosenthal, Yair (Rutgers University) ; Zhang, Hongrui (ETH Zürich) ; Ziveri, Patrizia (Universitat Autònoma de Barcelona.

Published alkenone εp records spanning known glacial pCO2 cycles show considerably less variability than predicted by the diffusive model for cellular carbon acquisition and isotope fractionation. We suggest this pattern is consistent with a systematic cellular enhancement of the carbon supply to photosynthesis via carbon concentrating mechanisms under the case of carbon limitation during low pCO2 glacial time periods, an effect also manifest under carbon limitation in experimental cultures of coccolithophores as well as diatoms.

Modern primary productivity on the Agulhas Bank, off South Africa, has been proposed to be linked to the midlatitude westerlies. A paleoproductivity record from this area may therefore resolve temporal changes in the westerly dynamics. [...]
