Thermal Stratification
Stratification of ocean water is a naturally occurring phenomenon that is important of the structure, circulation and productivity of the ocean. The formation of vertical stratification in the water column is a consequence of water masses with different densities.
Lesson objective:
After completing laboratory activity, students will be able to explain how density differences affect stratification, some causes for stratification, and how mixing affects a water column with different density properties.
