Message from the Guest Editors
Dear Colleagues,
The dynamics of estuarine and coastal waters can be observed from space. The images we see reveal that water is not just blue but shows a whole range of colours from blue to green, to red, yellow and brown. These changes in colour are caused by a combination of spectral absorption and scattering properties caused by the three main optical components: phytoplankton, coloured dissolved organic matter (CDOM) and suspended particulate matter (SPM). CDOM shows a logarithmic absorption curve with the highest absorption in the blue. High CDOM waters are dark and heat up very quickly. Inorganic SPM mostly scatters light and often makes the satellite images look brighter. Phytoplankton both absorbs and scatters light. The spectral absorption of living algal cells shows a characteristic spectral shape with peak absorptions in the red and in the blue. Thus, estuarine and coastal waters are optically very complex, meaning that, the retrieval of quantitative metrics of water quality and productivity from remote sensing data is still a challenge and requires knowledge of the local or regional specific inherent optical properties, i.e. absorption and scattering properties
