Abstract:
Down core marine sediment samples from ODP Site 1240 have been used for the analysis of the C28 and C30 1,14-diols, the C37:2 and C37:3 long chain ketones (alkenones) and the 24-methylcholesta-5,22-dien-3β-ol (brassicasterol) as proxies of primary productivity. Alkenones were also used to infer past sea surface temperatures through the unsaturation index UK'37. The C29 n-alkane was measured to obtain information on continental material inputs. δD of C37-alkenones and δ¹⁸O-seawater of Globigerinoides ruber were used as indicators of relative salinity changes. This data has been used for the study of the period between 150 and 110 ka (sediment depth from ca. 13 to 17 m), according to the age model from Rippert et al. (2017).
