Abstract
The hydrodynamic data in estuary is highly influenced the flow carried substances (pollutant, organic carbon, or inorganic matter) transport fate in estuary, but hard to obtain without professional hydrological monitor equipment. Here, an analysis water flow direction by biomarkers method was applied in Yellow River Estuary. Result shows pelagic bacteria community in Yellow River Estuary samples can be categorized into at least three distinct zones based on cluster analysis. In pelagic community, Flavobacteriaceae, Gammaproteobacteria, Robiginitalea, and Desulfobacterales were biomarkers from Bohai Bay, Laizhou Bay, Yellow River, and Central area of Bohai, respectively. The possible surface water flow direction of each Yellow River Estuary zones could be analyzed based on biomarkers abundance increase or decrease directions. Although without real-time hydrological data validation, utilizing biomarker tracing water flow represents a potential cost-effective and non-instrumental method for monitoring estuary water transmission. This research will greatly help the flow carried substances transport fate analysis in estuary.
