Suspended particulate organic carbon (POC) and sedimentary total organic carbon (TOC) in coastal areas play critical roles in the global carbon cycle, yet sources and dynamics of coastal POC and TOC have been affected by various anthropogenic activities such as aquaculture, sewage discharge, dam construction and land reclamation. To better understa...

Recently, glycerol dialkyl glycerol tetraethers (GDGTs) have been successfully used to identify different sources for organic-matter in the offshore and open ocean areas, while their applicability in the coastal areas remains unclear. This study was carried out to investigate the behavior of GDGTs and their applicability as indicators for organic-m...

... S. alterniflora has been introduced into the region since the 1990s, has expanded at a rate of 4.28 m/year (Zhu et al., 2019), occupies 49.7 ha, and even has the potential to replace entire mangrove forests under the influence of strong human activities (Feng et al., 2017). In addition, the mariculture ponds distributed along the two sides of the ZJE and Dongshan Bay outside the estuary cover areas of 980 and 7,380 ha, respectively (Gao et al., 2021). ...
... However, most of the isotopic studies of nitrogen until 1971 used 15 N-enriched/ 34 S or 15 N-depleted tracers which provided the compositional values of organic matter sources in aquatic systems (Table 4). Kohl et al. (1971) published the natural abundance of N in their research and provided a quantitative approximate of the fertilizers contributing to nitrate pollution in the U.S. A. Thus, it was observed that natural isotopic data could help in identifying the sources of nitrate pollution (Kusch et al., 2021;Cheng et al., 2021). A vast amount of literature exists concerning the analysis of oceanic N cycles through the application of stable isotopes. ...
