This course is a broad introduction to the interconnected physical, chemical, biological and geological aspects of the oceans. Topics may include: physical and chemical properties of seawater, and what their distributions tell us about ocean circulation; the role of the oceans and ocean currents in Earth's climate and El Nino; an introduction to waves and tides; modern ocean measurement technologies such as robot gliders and satellites; place tectonics and the formation and structure of the seafloor; marine biology and ecosystems; marine resources and environmental management.
