Marine and terrestrial biomarker records for the last 35,000 years at ODP site 658C off NW Africa

Major sources of MeO/OH-BDEs in the East China Sea elucidated from their records and phytoplankton biomarkers

“…Recent studies have proposed new indices based on biomarker ratios to identify and evaluate the contributions of TOM/MOM in sedimentary OM (Xing et al, 2011b). One index is the terrestrial and marine biomarker ratio (TMBR) (Xing et al, 2011b), defined as the relative abundance of SC 27 þ C 29 þ C 31 n-alkanes, which are the most abundant n-alkanes produced by high plants (Xing et al, 2011a(Xing et al, , 2011bZhao et al, 2000) to the sum of SC 27 þ C 29 þ C 31 nalkanes and SA þ B þ D. We define a new indicator of MTOC to represent MOM, which is calculated as…”

Use of lipid biomarkers for identification of regional sources and dechlorination characteristics of polychlorinated biphenyls in the East China Sea

“…Multiple biomarker-based proxies have a good potential for evaluating TOM inputs and contributions on sedimentary OM in many ocean systems (Amo and Minagawa, 2003;Xing et al, 2011b;Zhao et al, 2000). In the ECS, TOM from YR are mainly preserved in the inner shelf from YR mouth to the Zhejiang-Fujian coastline (Xing et al, 2011b).…”

“…Recently, some lipid compounds derived from plants, bacteria, or archaea, such as long-chain odd-carbon n-alkanes, long-chain even-carbon n-alkanols, and fatty acids, have been proposed as useful biomarkers for evaluating TOM contributions on sedimentary OM (Amo and Minagawa, 2003;Xing et al, 2011aXing et al, , 2011bZhao et al, 2000). Brassicasterol, dinosterol, and C 37 alkenones produced by marine algae are reliable MOM indicators.…”

Biomarker Evidence of Relatively Stable Community Structure in the Northern South China Sea during the Last Glacial and Holocene

“…For core MD05-2904, the average SST during the LGM was the lowest, a feature that was observed in several cores from the northern SCS (Huang et al 1997a;Pelejero et al 1999a). On the other hand, a high resolution record from the southwestern SCS (MD972151) showed that the SST minimum occurred near the Heinrich event 1 (H1) (Zhao et al 2006a), a feature that has been observed in several cores from the Atlantic (Mix et al 1986;Zhao et al 2000). As a preliminary attempt, we would correlate the low SST event at 440 cm to the Oldest Dryas in Europe or the H1 in the North Atlantic Ocean, the SST warming at 400 to 340 cm to the Bølling/Allerød and IS1 warm event, and the low SST centered around 290 cm to the Younger Dryas.…”
