Nuclear magnetic resonance (NMR) is a type of radio-frequency spectroscopy based on the magnetic field generated by the spinning of electrically charged atomic nuclei. This nuclear magnetic field is caused to interact with a very large (1 T - 5 T) magnetic field of the instrument magnet. NMR techniques have been applied to studies of electron densities and chemical bonding and have become a fundamental research tool for structure determinations in organic chemistry.
The relationship between the temperature (T) and the salinity (S) of a seawater can be illustrated graphically on a T-S diagram, which is a simple, but powerful tool used in studies of seawater density, mixing, and circulation. In a T-S diagram, temperature is plotted along the vertical axis in degrees Celsius and salinity is measured along the horizontal axis in PSU (Practical Salinity Units). Seawater density is illustrated in the diagram by curved lines of constant density (isopycnals). Water tends to move horizontally throughout the deep ocean, moving along lines of equal density.
