Sediment biogeochemistry in the Pearl River Estuary Region: carbon, nitrogen, and phosphorus cycling

In this project, we measure water column and sediment oxygen in the Pearl River Estuary and its adjacent coastal shelf in South China Sea in the summer of 2021 to understand the formation of hypoxia.
