摘要	The implementation of Water-Sediment Regulation Scheme in the summer season has introduced a new hydrological regime to the Yellow River downstream since AD 2002. The contribution and fate of the soil organic carbon from the Yellow River that reaches the deltaic and coastal environments are important to understand the regional and global carbon cycle. Glycerol dialkyl glycerol tetraethers (GDGTs) are biomarkers with potential implications in the reconstruction of soil OC transportation and paleo-environmental information. In this study, we collected suspended particulate matter samples from downstream waters of the Yellow River from September 2012 to October 2013 to assess 1) the sources of GDGTs, 2) the impact of the operations of reservoirs on the distribution and transportation of GDGTs to the Yellow River estuary region, and 3) the potential implications of GDGTs as proxies for paleoenvironment reconstruction. Our results suggested that over this annual cycle, more than 72.7% of the particulate isoprenoid GDGTs and 82.6% of the particulate branched GDGTs to the Yellow River estuary region were attributed to the intensive discharge during the Water-Sediment Regulation period. The overall GDGT-based BIT (index of branched and isoprenoid tetraethers) values for the particulate matters exported to the Yellow River-dominated continental margin through this annual cycle were higher than 0.5, and thus were capable of tracking soil organic carbon input. As the contribution of soil-derived GDGTs from the Yellow River would potentially influence the GDGT-based TEX86 and CBT-MBT temperature proxies in the estuary-coastal region, a careful examination is required before applying these proxies to temperature reconstruction in deltaic and coastal areas.
