Applied Physical Oceanography
Description
This two-day course covers the physical (emphasis on physics) concepts and some of the mathematical background of this exciting field of oceanography. It is designed as a primer for the professional who wants to learn more about the broad field of physical oceanography. There will be a strong emphasis on understanding the basic ocean processes. The course begins with a description of how the ocean system works and the basic governing equations. Other topics range from fundamental small waves to planetary-scale ocean currents, as well as some of the instruments employed to measure them, e.g., Satellite Altimetry. Additional subjects include boundary layers, waves, tides, Ekman flow, and the Gulf Stream. Also studied will be the ocean processes that impact our climate such as El Niño and the Thermohaline Conveyor Belt. It concludes with some research in tide measurements and a discussion of the ‘smaller’ seas, such as the Arctic Ocean!
Course Outline:
- Importance of oceanography
- Physics of the ocean
- Energetics of the ocean and climate change
- Wind patterns, El Niño and La Niña
- Satellite observations, altimetry, earth's geoid and ocean modeling
- Inertial currents, Ekman transport, western boundaries
- Ocean currents, modeling and observation
- Mixing, salt fingers, ocean tracers and Langmuir circulation
- Wind generated waves, ocean swell and their prediction
- Tsunami waves
- Internal waves and Synthetic Aperture Radar (SAR) sensing of internal waves
- Tides, observations, predictions and quality control
- Bays, estuaries and inland seas
- The future of oceanography
- Models and Databases
Who Should Attend:
This course is designed for engineers, physicists, acousticians, climate scientists, environmentalists, and managers who wish to enhance their understanding of this discipline or become familiar with how the ocean environment can affect their individual applications. For example, a marine radar expert could learn that ‘sea clutter’ is actually a ‘signal’ from the radar return from capillary waves.
