The course prepares students to analyze data documenting properties of the sea, to describe spatial and temporal distribution of the properties in the world seas and oceans, and to perform elementary modeling of the properties.
Subject of the course and methodology. Measurement of salinity, temperature and pressure, determination of density, analysis of water masses. Measurement of currents
(indirect methods, direct methods according to Lagrange and to Euler), of high frequency (wave gauge) and low frequency (tide gauge) sea level variability. Equations of motion and continuity, equation of state and its approximations, equations of heat and salt exchange. Properties of the seas and oceans: salinity, temperature, pressure, density, water masses. Basic modeling of the spatial distribution of salinity and temperature and of the annual temperature cycle. Exercises include analysis of vertical profiles of salinity and temperature and of horizontal distribution of these properties using subjective and objective methods. Vertical distribution of the pressure is considered as well, utilizing measured profiles of salinity and temperature.
Students will be able to
1. analyze salinity and temperature data,
2. describe properties of the world seas and oceans,
3. identify factors controlling spatial distribution and temporal variability of the properties,
4. solve equations of the conservation of salt and heat that capture properties of the sea.
1. Following the lectures as well as studying the lecture notes and literature,
2. analyzing the data (vertical and horizontal distribution).
