The advent of Earth-observing satellites has revolutionised the gathering of oceanographic data and the visualisation of oceanographic processes. This course was for postgraduate students and young post-doctoral research workers and covered the instruments and satellite systems used to gather visible, infrared and microwave data over the oceans. It also covered the uses of these various types of data to provide information about ocean colour, biological productivity, surface temperature, currents and circulation patterns, near-surface windspeeds, bottom topography and the geoid.
