Lesson 1: Observing the Amazon River Plume
Measurement of sea surface salinity (SSS) from space began with the launch of the ESA Soil Moisture and Ocean Salinity (SMOS) satellite in November 2009. One of the most obvious features when looking at SMOS data is the input of freshwater from the Amazon River. The Amazon also delivers a vast quantity of nutrients into the Atlantic, which encourages the growth of phytoplankton. This lesson uses these two features of the impact of the Amazon to compare the spatial scales over which changes in salinity and ocean colour can be viewed using EO data.
Level: Intermediate. Suitable for students with some background in oceanography.
