文摘
- •
Bottom waters have higher particulate organic matter (POM) content than surface water.
- •
N-alkane biomarkers indicate bottom water POM has higher levels of terrestrial organic matter than surface waters.
- •
Terrestrial-sourced N-alkanes show a distinct drop indicating loss of POM across the estuarine turbidity maximum.
- •
Discharge, seasonality, and tidal phase affect the amount, transport, and sources of POM.
