  • Sediment cores in four sites of the red-tide-frequent-occurrence area in East China Sea were selected and source apportionment was calculated using two end-member modeling for δ13CTOC to derive an inventory of marine versus terrestrial organic matter. The n-alkanes and fatty alcohols in sediment cores were analyzed to discuss composition, distribution and origins of organic matter. The results indicate that the n-alkanes have obvious advantages of longer carbon number, and the longer chain n-alkanes have a strong odd-over-even predominance and display bimodal distribution. Downhole variations of total n-alkanes (T-ALK/μg/g) contents are different among four cores. It is indicated by CPI, TAR, Pmar-aq and other n-alkanes that sedimentary organic matter is majorly from terrestrial inputs with predominance of herbaceous plants. The results of n-alkyl alcohol showed that organic matter mainly originated from terrestrial higher plants. The distribution of phytol in four stations are similar suggesting that they may experience through the similar biochemical process and the sedimentary environment may be relatively constant. Donwhole variation in the ratio of brassicasterol and dinoflagellatesterol indicates that red-tide blooms have changed from single diatom type into complex one with diatom and dinoflagellate due to deteriorated eutrophication.

Distribution and Sources of n-alkanes and Fatty Alcohol in Core Sediments of Red Tide-frequent-occurrence Area in the East China Sea

Abstract: Sediment cores in four sites of the red-tide-frequent-occurrence area in East China Sea were selected and source apportionment was calculated using two end-member modeling for δ13CTOC to derive an inventory of marine versus terrestrial organic matter. The n-alkanes and fatty alcohols in sediment cores were analyzed to discuss composition, distribution and origins of organic matter. The results indicate that the n-alkanes have obvious advantages of longer carbon number, and the longer chain n-alkanes have a strong odd-over-even predominance and display bimodal distribution. Downhole variations of total n-alkanes (T-ALK/μg/g) contents are different among four cores. It is indicated by CPI, TAR, Pmar-aq and other n-alkanes that sedimentary organic matter is majorly from terrestrial inputs with predominance of herbaceous plants. The results of n-alkyl alcohol showed that organic matter mainly originated from terrestrial higher plants. The distribution of phytol in four stations are similar suggesting that they may experience through the similar biochemical process and the sedimentary environment may be relatively constant. Donwhole variation in the ratio of brassicasterol and dinoflagellatesterol indicates that red-tide blooms have changed from single diatom type into complex one with diatom and dinoflagellate due to deteriorated eutrophication.
