Total organic carbon (TOC), total nitrogen (TN), stable isotopes (δ 13 C and δ 15 N), lipids and biogenic silica (BSi) from a high-resolution sediment core east of Hong Kong span the interval from 1925 to 2001. Organic matter (OM) within this core (E2) is derived from both marine phytoplankton and terrestrial material as deduced from the range of values of δ 13 C org ...
The isotopic composition (δ 13 C and δ 15 N) and organic carbon (OC) and total nitrogen (TN, organic plus inorganic) content of 37 carbonate-free surficial sediments of the subtropical Pearl River estuary and the adjacent shelf of South China Sea (SCS) was determined. The δ 13 C values indicate that the sediment organic material is a mixture from two sources, terrestrial and...
