“…Typical carotenoid biomarkers for diatoms and dinoflagellates were nearly absent in surface sediments, an observation that the authors attributed to rapid degradation because of the presence of labile 5,6-epoxides in these carotenoids. In this respect, note that Klok et al (1984) estimated that the concentration of loliolide, one of the principal degradation products (Repeta, 1989), was -2% of the total organic matter of a diatomaceous ooze from the Walvis Bay upwelling area.…”

Deep-sea sediment samples from three Ocean Drilling Program (ODP) Leg 112 sites on the Peru continental margin were investigated, using a number of organic geochemical and organic petrographic techniques, for amounts and compositions of the organic matter preserved. Preliminary results include mass accumulation rates of organic carbon at Site 679 and characteristics of the organic facies for sediments from Sites 679, 681, and 684.

Despite carotenoids being abundant natural products, there are only scattered literature reports of carotenoid derivatives (mainly in the form of their 'perhydro' derivatives) in ancient sediments and petroleum. This was thought to be due to the sensitivity of carotenoids toward oxygen and their preservation potential in sediments was judged to be low. Detailed studies in the past years have indicated, however, that the fossil 'perhydro' derivatives of carotenoids represent only the tip of the iceberg and that a number of reactions occurring with the polyene chain (i.e. expulsion of toluene and xylene, cyclisation and aromatisation, reaction with reduced inorganic sulfur species, hydrogenation, C-C bond cleavage) determine the fate of carotenoids in ancient sediments and lead to complex mixtures of carotenoid derivatives. In addition, aromatisation of cyclohexenyl moieties (as present in e.g. pcarotene) occurs. An overview of these reactions is given.

Organic geochemical data are presented for two Pliocene sapropels recovered during Ocean Drilling Program (ODP) Leg 160 in the Eastern Mediterranean Basin. One sapropel from Site 969 is exceptionally rich in organic carbon (TOC up to 30%) and the other one, from Site 967, has a more typical organic carbon content (TOC up to 8%). The majority of the solvent extractable organic matter of these sapropels can be ascribed to autochthonous sources. Higher plant-derived organic compounds are present in only minor amounts. Pyrolysis gas chromatography-mass spectrometry (GC-MS) analyses of the bulk organic matter also indicates that the contribution of terrestrial organic matter to these sapropels is insignificant. The presence of biomarkers derived from green sulfur bacteria, which are indicative of anoxygenic photosynthesis, show that during sapropel formation anoxia was not merely confined to the lower parts of the water column but, in fact, extended into the photic zone, resulting in an almost completely euxinic water column, a setting similar to the present-day Black Sea. Furthermore, it is proposed that these paleoenvironmental conditions have been a major controlling factor in the accumulation of organic matter in these sapropels.
