Remote sensing techniques in oceanography are a powerful tool to investigate whole ocean basins synoptically. The information contained in one satellite scene can not be gathered as cost-effectively with any other method. There are a whole variety of satellite-borne sensors used in oceanography, e.g. optical satellites to derive water quality, as well as microwave to derive sea-surface temperature. The advantages and limitations of the different techniques will be discussed.
These techniques can give us valid information about mesoscale structures as well as basin circulation, and wind driven processes such as coastal up-welling.
Satellite images can be used to explain physical drivers for certain biological processes such as the development and occurrence of algal blooms. In this talk we show how ocean colour sensors are currently being used for investigations of oceanographic features and water quality in the Baltic Sea. We also discuss the possibilities for using this method in coastal zone management.
