Content:
Major advancement in the U-Th measurement techniques since the 1990's have resulted in new opportunities for the use of these nuclides to probe into aquatic processes in greater detail. This volume provides state-of-the-art reviews on the applications of U-Th series nuclides to ""time"" and ""tag"" in a variety of processes occurring in aquatic systems.* this book provides state of art reviews on the applications of U-Th Series nuclides to 'time'and 'tag' key processes occurring in aquatic systems.* the book is self-contained, each chapter presents nuclide source functions, process
