Hydrogen isotopic composition of C₃₇ alkenones and the ecology and physiology of coccolithophores

Creator:

Wolhowe, Matthew D.

Abstract:

A three-part study was conducted into the impact of physiological and ecological variables on the net isotopic fractionation of hydrogen, α[subscript K₃₇], expressed in C₃₇ alkenones. First, alkenone-producer production, abundance, and export were characterized in the summertime Gulf of California and Eastern Tropical North Pacific using compound-specific, labeled in situ...

Determination of unsaturation-, growth phase-, and growth rate-dependent hydrogen isotopic fractionation in C₃₇ alkenones produced by Emiliania huxleyi

Creator:

Wolhowe, Matthew D.

Abstract:

Recent works have investigated use of the hydrogen isotopic composition of C₃₇ alkenones (δD[subscript K37s]), lipid biomarkers of certain haptophyte microalgae, as an independent paleosalinity proxy. I discuss herein the factors impeding such an application and identify the potential alternative use of δD[subscript K37s] measurements as a proxy for non-thermal,...
