If the distribution of brGDGTs produced in the marine environment is different to that of the brGDGTs coming from the continent, the distribution of the brGDGTs can give an indication about the origin of the brGDGTs in the marine environment (Zell et al, 2014a,b).…”

“…Furthermore, brGDGTs are also produced in the marine environment, but in much lower concentrations than in continental Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/csr settings, therefore the marine production does not have a strong influence on the BIT index (e.g. Hu et al, 2012;Peterse et al, 2009;Weijers et al, 2014;Zhu et al, 2011). Overall, this means that the BIT index is influenced by various factors and does not only indicate organic matter coming from soils, but rather a more general continental signal.…”

“…Schouten et al (2007) found brGDGTs also in sediments and microbial mats in hot springs. Hu et al (2012) detected brGDGTs in pelagic sediments in locations where the contribution from soils can be discounted. These findings indicate that brGDGTs can be produced not only in soils but also in aquatic environments.…”

Accurate reconstruction of past sea surface temperature (SST) is important for the understanding of past climate and its variations. Recently, the TEX 86 indicator (TetraEther indeX of tetraethers consisting of 86 carbon atoms), based on glycerol dialkyl glycerol tetraethers (GDGTs) has been developed into a promising proxy for SST reconstruction. In this study, we investigated the distribution of GDGTs in surficial sea bottom sediments from coastal and open marine settings around China between 18°N and 38°N in water depth of either b100 or N 1000 m. As the distribution patterns of GDGTs reflect their biological sources and their respective habitats these can be identified from the sediment samples investigated. The distributions of branched GDGTs (brGDGTs) in the Yellow Sea (YS) was found to be similar to that of the lower Yellow River basin indicating that the brGDGTs in the YS originated from terrestrial soil. While the variability of the cyclisation ratio of branched tetraethers (CBT)-derived pH values in the Pearl River estuary (PRE) suggested that brGDGTs might also be produced in situ in coastal sediments or in the water column. In the shallow areas (water depth b100 m, the YS, East China Sea and PRE) TEX 86 H -based SST (SST 86 H ) was overestimated or underestimated when compared with mean annual SST satellite , most likely caused by seasonality or overprint by a cold-biased terrestrial signal. In the South China Sea (SCS), at water depth N 1000 m, the SST 86 H matched well the mean annual SST determined by satellite, indicating the applicability of the TEX 86 H temperatures for paleoclimate investigations in these study areas and, potentially, in similar settings of deep water. These findings provide the basis for application of branched/isoprenoid index (BIT) and TEX 86 as indicators for temperature and paleotemperature in coastal and open marine environments around China.

“…Recently, the in situ production of marine br GDGTs has been increasingly observed (Peterse et al, 2009;Zhu et al, 2011;Hu et al, 2012;Weijers et al, 2014). This has raised concern that an increase in a marine component of br GDGTs may bias the reconstructed paleo continental temperature (Sanchi et al, 2014).…”
