Why is it Important to Understand Ocean Salinity?
Ocean salinity plays key roles in the global hydrological cycle, ocean circulation and in regulating Earth's climate. Today's scientists
know that Earth's water cycle is dominated by exchanges between the ocean and atmosphere, with sea surface salinity (SSS) varying
because of freshwater input and output, via the processes of evaporation and precipitation.Having a better understanding of the processes of evaporation and precipitation and how changes to these processes may influence the global hydrological cycle and ocean circulation will improve our abilities to monitor, understand and model the water cycle over the oceans. The ocean is an uncontaminated source for understanding these influences by measuring the changes in salinity and relating them to the changes we see in the water cycle. Featured Video: Why SPURS?

This activity focuses on two aspects of the water cycle: evaporation and condensation
