The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...

Now that you know the ocean has layers, let's name them. The seventh installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program covers terminology associated with ocean layers, such as thermocline and...

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

The instructions for demonstrating ocean turnover are provided in this resource. You could set this up for your earth science class as part of a lecture on convection currents or as an explanation of how ocean currents form. An animation...

While the topic of this investigation is not specific to any particular discipline of science, it does serve as a practice of the scientific method. Learners set up a bowl containing boiling water, one with room temperature water, and...
