Catalog Entry

GEOL 365. Oceanography
Three hours lecture; two hours laboratory (4).

Prerequisites: Eight hours of any of the following natural sciences: Astronomy, Biology, Chemistry, Geology, Meteorology, Physical Science Processes, or Physics

Introduction to the physical, chemical, geological, and biological processes in the marine environment and their interaction. Includes analysis of topical issues such as global climate and sea level changes, mineral and energy resources from the sea, marine pollution, and law of the sea. Student may not receive credit if previously taken GEOL 361 and GEOL 362.

Detailed Description of Conduct of Course

The following instructional strategies will be utilized: (1) lecture by professor with classroom discussion encouraged; (2) laboratory activities in which students may work alone or in teams to complete exercises on topics supplemental to the material presented in lecture; and (3) use of audiovisual materials such as videos and slides. Occasionally, an extra reading assignment beyond the required textbook and workbook will be required involving a journal article on an especially new or relevant topic.

 

Goals and Objectives of the Course

 Having successfully completed the course, the student will:

1. have a basic understanding of the origin and uniqueness of Earth's oceans.
2. be familiar with the principal techniques used to study the oceans.
3. know the basic biological, chemical, geological, and physical processes operating in the marine environment and how they interact.
4. develop a deeper understanding of the crucial environmental and legal issues arising from human interaction with the oceans, including management and development of shorelines, extraction of mineral, biological, and energy resources from the sea, and marine pollution.
5. have used a systems analysis approach to study the linkages between Earth's hydrosphere, lithosphere, biosphere, and atmosphere.

 

Assessment Measures.

 1. Lecture written examinations
2. Laboratory workbook activities
