In this book, different analytical tools including Accelerator Mass Spectrometry (AMS), Isotope Ratio Mass Spectrometry (IRMS), Nuclear Magnetic Resonance Spectroscopy (NMR), Bayesian Isotope Modeling, and Serial Thermal Oxidation Isotope Analysis were used to investigate the transformation and fate of carbon in Lake Superior and some of the tributary streams and rivers. The book covers analyses of the concentrations and carbon isotopes of lake water dissolved inorganic carbon, particulate organic carbon and dissolved organic carbon, organic matter derived from ultrafiltration and solid phase extraction, the biological macromolecules carbohydrates, proteins and lipids, and the food sources of mesozooplankton. This book will be a good resource for students, water quality monitoring managers, and professors of Biochemistry, Limnology, Chemistry, Marine sciences, Earth system sciences, Geochemistry, and Environmental sciences, and also for State and Federal agencies such as Department of natural resources and the Environmental protection agency.
