2017/4/11
A cultured strain of Isochrysis galbana UTEX LB 2307 was grown at 20°C and 15°C under salinity of 35‰, 32‰,
27‰, 20‰, and 15‰, and analyzed for long chain (C37–C39) alkenones and (C37–C38) alkyl alke...
Growth phase dependent hydrogen isotopic fractionation in alkenone-producing haptophytes
Growth phase dependent hydrogen isotopic fractionation alkenone-producing haptophytes
2010/1/20
Recent works have investigated use of the hydrogen isotopic composition of C37 alkenones (δDK37s, lipid biomarkers of certain haptophyte microalgae, as an independent paleosalinity proxy. We discuss h...
Modelling an alkenone-like proxy record in the NW African upwelling
Modelling alkenone-like proxy record NW African upwelling
2010/1/13
A regional biogeochemical model is applied to the NW African coastal upwelling between 19° N and 27° N to investigate how a water temperature proxy, alkenones, are produced at the sea surface and reco...
