This course introduces the fundamentals of physical oceanography, including governing equations, physics and dynamics, as well as methodology and applications. This course will emphasize these following contents: 1) governing equations of ocean circulation and their dynamics interpretation; 2) temporal and spatial scale of ocean circulations; 3) wind-driven and thermohaline circulation in the global ocean; 4) the cross-scale basin-slope-shelf circulations; and 5) waves and tides in the ocean. Students are required to understand the mathematics of those theories, their dynamics implementation, especially their realistic/theoretical applications in understanding the multiscale processes in the ocean.
