GS 108 General Science: Oceanography
Lecture Hours: 3
Lab Hours: 3
Credits: 4
Surveys the four classic disciplines of the ocean sciences: geological oceanography, chemical oceanography, physical oceanography, and biological oceanography. Focuses on the basic principles of the ocean sciences and stress the interdisciplinary nature of oceanography.
Prerequisite: Placement into WR 115 (or higher), or completion of WR 090 (or higher) with a grade of C or better; or consent of instructor.
Student Learning Outcomes:
- Evaluate the special nature of the Earth as a “water” planet.
- Interpret the features of the ocean floor and margins and relate these structures to modern theories of crustal origin.
- Describe basic chemical oceanography in terms of the special properties of water.
- Analyze the motions of the sea currents, waves, and tides in terms of causes, and their influences and effects upon the land.
- Characterize and explain the adaptations of marine taxa.
- Assess the resources of the sea.
- Appraise the impacts of humans on the marine environment.
- Evaluate experiments or observations that have led Earth scientists to model the Earth as a planet sensitive to changes in the atmosphere, ocean, and interior.
Statewide General Education Outcomes:
- Gather, comprehend, and communicate scientific and technical information to explore ideas, models, and solutions and generate further questions.
- Apply scientific and technical modes of inquiry, individually, and collaboratively, to critically evaluate existing or alternative explanations, solve problems, and make evidence-based decisions in an ethical manner.
- Assess the strengths and weaknesses of scientific studies and critically examine the influence of scientific and technical knowledge on human society and the environment.
