Ocean Water: Density part of Cutting Edge:Oceanography:Activities
In regions throughout the world oceans, water moves vertically to or down away from the surface and is set in motion by atmospheric winds, salinity and temperature differences. Cold water is much denser than warm and seawater has a higher density that fresh water and will sink below the less dense layer of water. Furthermore, vertical mixing powered by atmospheric winds can affect stratification and the rate of growth of the surface boundary layer. This lab activity is a simulation of the processes that create density stratification in ocean environments. It exposes students to concepts of temperature, salinity and wind and the role each plays in the development of water stratification.
Essentials of Oceanography/lab part of Cutting Edge:Oceanography:Courses
This introductory course for the marine biology major exposes students to basic principles of physical, chemical and geological oceanography. This course should help students to achieve a greater understanding of the ocean, its processes and its impact on the biology of the ocean. Information to be covered: Formation and structure of ocean basins (plate tectonics, continental margins, deep abyssal plains, ridges and trenches; Geochemistry of seawater (physical properties of water, salinity, identification of water masses based on density, the physical description of ocean surface (waves, and tides), General oceanic circulation patterns (fluxes of energy at the ocean-atmosphere interface, drift and geostrophic currents, thermohaline circulation); Air-sea interaction (Coriolis-effect, oceanic heat flow and atmospheric circulation) Biological oceanic populations as a function of diverse physico-chemical variables (dissolved and particulate matter, nutrient cycles, particulate fluxes and marine sedimentation); Theoretical aspects of oceanography will be followed by regional case studies of coastal systems and an introduction to the state of the environment in the Oceans (i.e. sea level rise, contamination, oil spills, fisheries exploitation).
