Ocean Learning Hub Woods Hole Oceanographic Institution The density of seawater plays a vital role in causing ocean currents and circulating heat because of the fact that dense water sinks below less dense. salinity, temperature and depth all affect the density of seawater. Discover the ocean learning hub—your gateway to trusted ocean science content. easily explore by topic, media type, grade level, and educational standards.
Labxchange Density: sink or float? this activity demonstrates density differences in ocean and coastal waters and how these differences drive currents. Discover more about water denisity and then use the article ocean density to further explore how salinity, temperature and depth all affect the density of seawater. In oceanography, density is used to characterize and follow water masses in studying ocean circulation. density is a measure of the compactness of material, or how much mass (stuff) is “packed” into a given volume (space). O comparison of the seawater densities recorded in the table shows that the density of sample “c” is less than, equal to, or greater than (choose one) the density of samples “a” and “b” prior to mixing.

O comparison of the seawater densities recorded in the table shows that the density of sample “c” is less than, equal to, or greater than (choose one) the density of samples “a” and “b” prior to mixing. Students explore the concept of density, in particular the density of liquids, and how denser substances sink below substances that are less dense. in the second simulation activity, they apply these ideas as they predict, observe and explain density driven currents in a model ocean. Discover how temperature and salinity shape ocean density—and how even tiny differences help drive the powerful flow of deep ocean currents. Dr mike williams explains how the density of the seawater is measured, by looking at the conductivity and temperature of the water. the article ocean density further explores how salinity, temperature and depth all affect the density of seawater. The highest density water in the ocean is generally found in the deepest ocean depths. seawater density can be affected by salinity, temperature, and pressure and how these interact are important to how the ocean works.
