### Physical Oceanography (Winter 2017)

MWF, 11.00 to 11.50, L+R 135

#### Course syllabus

This course is an introduction to Physical Oceanography. The primary focus of the course is on ocean circulation and how it impacts the Earth's climate system. We will begin by considering how we observe and model the ocean. We will then move on a basic overview of key dynamical balances in the ocean and the resulting flows. From there we will develop the theory behind the wind-driven gyre circulation, ocean ventilation and the global meridional overturning circulation.
