This video of the seafloor in Barrow Canyon, off the coast of Alaska is to accompany the presentation, 'The Arctic Ocean Ecosystem: Status and Trends in the Pacific Arctic' by Jacqueline Grebmeier, given during the 2012 Arctic Ocean Ecosystem Workshop.
This lesson answers the question: How does ice floating on the ocean act as it melts?
Objective
* Students will learn about temperature, salinity and their effect on density.
* Students will learn that ocean currents are caused by differences in densities as a result of temperature and salinity. These differences allow ocean currents to circulate water
