Course Objectives: | In this course we will learn about the physical forces on Earth that cause ocean
motion and the geological forces that determine the ocean basin and coastal
morphologies. This course will provide the student with the necessary skills to
carry out mathematical calculations while understanding their limitations, and thus
giving a physical interpretation of the solutions obtained. Students will use real-
time observed data obtained from a number of sources to examine a specific feature
of interest and present their results to the class and in a project report.
We will examine the ocean and atmosphere as a coupled system driven by energy from
the Sun and how plate movements influence ocean circulation. Atmospheric
circulation creates the global ocean wind-driven surface currents and coupled
atmosphere-ocean processes create anomalies like El Nino. Deep ocean currents,
driven by density and meridional overturning circulation, further regulate climate
on Earth. We will also discover how waves are a mechanism that transports
information from one point to another point on Earth. We will then examine how the
Earth/Moon/Sun system causes large bodies of water to rise and fall as tides.
We will discuss origins and movement of marine sediments, and once we understand the
modern ocean, we use this knowledge on basic principles of marine geology to infer
ocean and climate changes over geologic time. We will address how sediments can
serve as archives of past climatic conditions, the causes of ice ages, how plate
movement influences ocean circulation and climate, explore long-term planetary
evolution, and discuss the impacts of human activities on future oceans and climate. |

Honor Code Reference: | It is the student's responsibility to be familiar with the Univeristy of Georgia's
policy on academic honesty as published in the booklet "A Culture of Honesty:
Policies and Procedures on Academic Honesty." Evidence of academic dishonesty will
be turned over to the Office of the Vice President for Academic Affairs for
consideration and possible action. The minimum penalty for a student found guilty of
academic dishonesty is a grade of "F" in the course and a note on the student's
transcript. There have been several changes in the academic honesty policy at UGA.
