Matter of Density
The focus of this lesson is factors affecting the density of seawater. In this activity, students will be able to explain the relationship between temperature, salinity, pressure, and density; the concept of sigma-t; and how density differences can affect the distribution of organisms in deep-sea environments. Given CTD data, students will be able to calculate density and construct density profiles of a water column.
