Physical Oceanography
Physical Oceanography is the study of the physical processes in the ocean and the interaction of the ocean with the atmosphere.
Oceanology is the scientific study of the sea by applying traditional sciences, such as physics, chemistry, mathematics, etc., to all aspects of the ocean.
In doing their work they often construct elaborate numerical models of the circulation, and they develop instruments used on ships and satellites.

Two types of ocean models -1
•Mechanistic models are simplified models used for studying processes. Because the models are simplified, the output is easier to interpret than output from more complex models.

Methods we study physical oceanography
As we study the ocean, we use
theory, observations, and numerical models to describe ocean
dynamics.
Neither is sufficient by itself.
Physical oceanographers study currents, tides, waves, and convection in the deep ocean, along coasts, and in the surf zone. They also study the heat budget of the ocean including solar heating, evaporation, radiation into and out of the sea, and the transport of heat and salt by currents.
•Many different types of simplified models have been developed, including models for describing planetary waves, the interaction of the flow with sea-floor features, or the response of the upper ocean to the wind. These are perhaps the most useful of all models because they provide insight into the physical mechanisms influencing the ocean.

Physical Oceanography
The goal of their work is to understand and predict the processes including such important processes as El Niño, tsunamis, tides, the role of the ocean in climate and the ice ages, and the influence of the oceans on local climate.

Two types of ocean models -2
Simulation models are used for calculating realistic circulation of oceanic regions. The models are often very complex because all important processes are included, and output is difficult to interpret.
Oceanography is the recording and description of the physical, chemical and biological characteristics of the ocean. This term inadequately describes modern scientific ocean investigations.

Combination of the methods
The ultimate goal is to know the ocean well enough to predict the future.
