| Abstract: | Individual neutral lipids, including hydrocarbons, ketones, alcohols, sterols, keto-ols and diols have been analysed from eight horizons in a sediment core taken from the Santa Catalina Basin, Calif. Variations in the concentration of individual lipid components between sites are studied using factor analysis to determine their inputs. Several sources of organic material are postulated from the composition of hypothetical factors, including methanogenic bacteria, higher plants and algae including coccolithophores, dinoflagellates and diatoms. Sources for long chain keto-ols and diols and a C35 bicyclic alkene are suggested as methanogenic bacteria and algae respectively. |
