General Oceanography I

Geology 111

Geology 111 is the first course in a two part General Oceanography sequence (Geology 112 being the second). This is a great multi-discipline science experience which covers all major branches of science. The course begins the study of oceans and ocean basins, covering such topics as the scientific method, history of oceanography, origin of the earth and its oceans, plate tectonics, paleomagnetism, ocean floor topography, marine geology, water chemistry, and climates. If you would like to know more about Oceanography I, keep reading. Otherwise, you can return to Geophysical Science's Homepage.

Course Goals

Geology 111 and 112 are college-level, introductory courses designed to give you a broad survey of the physical, chemical, geological, and biological processes of the oceans. The courses, however, do not presume that you have any prior knowledge of any science, however. In fact, if your general science background is weak, this should prove to be a great opportunity for you to learn more about science.

Lectures and laboratories are set up to compliment each other. The lectures provide opportunity for presentation of theory, while the labs give them some "hands on" experience with the concepts they learn in lecture.

Laboratory

The three hour laboratory periods emphasize empirical methods in oceanography. Numerous experiments and field trips will be conducted to give the student an idea on practical application of principles learned in the lecture.

Cruise

The ocean cruise is conducted aboard TCC’s research vessel, the R/V Matthew F. Maury, to give you insight as to how an oceanographer obtains data in the shipboard environment. The cruise is required and will be held on a weekend. It will take the place of the regularly scheduled laboratory period. Students should make arrangements to be available.

A typed (GSA format) paper based on the student's observations and participation in shipboard sampling procedures is required. The paper will focus on each sampling method and navigational aid.
