Studies of the Biogeochemistry of Typical Estuaries and Bays in China

This book presents study findings involving the Changjiang River estuary and Jiaozhou Bay, China, etc. It takes a large catchment as a combined ecosystem to study nutrients biogeochemistry and environmental aspects of the Changjiang River. Some of the findings have sparked new research directions, including systematic studies of nutrients in the Changjiang River; sources and control mechanisms of nitrogen and phosphorus in the Changjiang River and its estuary; removal and transport of nutrients in the turbidity maximum zone and upwelling area of the Changjiang estuary; long-term changes in nutrients and ecological responses in the Changjiang River estuary and Jiaozhou Bay; and a study on nutrient structure and nutrient composition of phytoplankton, which are topics at the forefront ofinternational marine

The studies address different fields, such as biogeochemistry, marine chemistry, ecology, environmental science, oceanography and biology.

Takes a large catchment as a combined ecosystem to study various biochemistry and environmental aspects of the Changjiang River Studies for the first time the behavior and removal of various forms of phosphorus and silica during estuarine mixing Suggests a new method for estimating the ratio of sediment resuspension in estuaries Proposes a new concept of nutrient structure as a basis for analyzing long-term changes in Jiaozhou Bay
