12.744 Marine Isotope Chemistry
Fundamentals of using isotopes to study processes and timescales for marine chemistry and geochemistry. Starts with a basic introduction to the nature, origins, and reasons for the distributions of isotopes in nature, then develops theory and approaches for radioactive dating methods. These are used to constrain the timing and nature of the geochemical evolution of the elements, solar system, earth, ocean and atmosphere. Cosmogenic isotopes and their applications are covered. Basics of mass spectrometry are briefly discussed, and then the principles and applications of isotope fractionation are more thoroughly dealt with. Introduction to mass independent fractionation and clumped isotope methods. Explores applications of isotope methods to a number of water column processes, including particle scavenging, sedimentation, long term element budgets, redox processes, and air-sea exchange. Emphasis will be on quantitative methods and problem-solving, and there will be four problem sessions with development of problem solutions.
