Data report: characterization of distributions of photosynthetic pigments in sapropels from Holes 966D and 969C

Abstract

The distribution of chlorins and carotenoids in 22 sapropel samples from Ocean Drilling Program Leg 160, Holes 966D and 969C, have been examined by combined liquid chromatography-mass spectrometry under atmospheric pressure ionization conditions. Up to 42 components were detected over the range of samples (including chlorphyllone a, pyrophaeophorbides, pyrophaeophytins, steryl chlorin esters a and b, as well as carotenes). The samples showed two basic types of pigment distribution, with no obvious relationship between these distributions and the sedimentological parameters.
