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.

This edited book is based on the accepted papers for presentation at the 1st MedGU Annual Meeting, Istanbul 2021. With three sections spanning a large spectrum of geological and geoenvironmental topics, this book presents a series of newest research studies that are nowadays relevant to Middle East, Mediterranean region, and Africa. The book includes major subjects related to hydrogeology, geoecology, and atmospheric sciences. Case studies are from the fields of hydrology, hydrogeology, hydrogeochemistry and water resources, biogeochemistry, geobiology and geoecology, atmospheric sciences, meteorology, climatology, and oceanography.

Revised and updated, Royce's Introduction to the Practice of Fishery Science is a classic text. With a new chapter on aquaculture, this book provides the background for a first course in fishery science. Intentionally focused on the practical and professional requirements of careers in the management and maintenance of fisheries, this text will be useful to students as well as to established professionals.

A major task for physical oceanographers is to determine the movement of oceanic water from observations. This book introduces the P-vector inverse method, with a two-step determination of the velocity from hydrographic data. The book provide insights into the basics of the P-vector inverse method and the features of the inverted global and regional ocean circulations. Upper undergraduate and graduate students as well as oceanographers, marine biologists and other environmental scientists will find this book a valuable tool for their studies.
