Portland Community College | Portland, Oregon

The purpose of this course is to gain knowledge and appreciation of oceanography.

The faculty has chosen the text and lab materials and the viewpoints shall be that of the author(s). This includes the topics of relativity, the geologic time scale, and the evolution of the Earth, solar system, and the galaxy and universe.

Students are expected to be able to read and comprehend college-level science texts and perform basic mathematical operations to successfully complete this course. 

Earth and space sciences are based on observations, measurements and samples collected in the field. Field-based learning is recommended by numerous professional Geology organizations, including the American Geological Institute and the National Association of Geoscience Teachers. Field-based learning improves both metacognition and spatial/visualization abilities while helping to transfer basic concepts to long-term memory by engaging multiple senses at the same time. Spatial thinking is critical to success in STEM (Science, Technology, Engineering, and Math) disciplines. Field work may include:

• Å·ÖÞ±­¾öÈü¾º²Âapp_Å·ÖÞ±­×ãÇòÍø-Ͷע|¹ÙÍøing skills in site characterization
• Application of key terms and concepts
• Measurement and data collection
• Interpretation of data and observations, and fitting them to a larger context

Field work may be physically challenging and may require overland travel on foot or other means to field sites, carrying equipment and supplies, and making measurements in unusual or awkward positions for a length of time.  Field work may include inherent risks (uneven terrain, variable weather, insects, environmental irritants, travel stress, etc.). Field work can be adapted to individual abilities.

Regarding the teaching of basic scientific principles (such as geologic time and the theory of evolution), the Portland Community College Geology/General Science Subject Area Committee stands by the following statements about what is science.

• Science is a fundamentally non-dogmatic and self-correcting investigatory process.  A scientific theory is neither a guess, dogma, nor myth.  The theories developed through scientific investigation are not decided in advance, but can be and often are modified and revised through observation and experimentation. 
• “Creation science,” also known as scientific creationism, is not considered a legitimate science, but a form of religious advocacy.  This position is established by legal precedence (Webster v. New Lenox School District #122, 917 F.2d 1004). 
• Geology/General Science instructors at Portland Community College will teach the generally accepted basic geologic principles (such as geologic time and the theory of evolution) not as absolute truth, but as the most widely accepted explanation for our observations of the world around us.  Instructors will not teach that “creation science” is anything other than pseudoscience.    
• Because "creation science", "scientific creationism", and "intelligent design" are essentially religious doctrines that are at odds with open scientific inquiry, the Geology/General Sciences SAC at Portland Community College stands with such organizations such as the National Association of Geoscience Teachers, the American Geophysical Union, the Geological Society of America, and the American Geological Institute in excluding these doctrines from our science curriculum.

Upon successful completion of the course students should be able to:

1. Explain the development and functioning of beaches, shorelines, and estuaries using an understanding of waves, tides, and coastal processes.
2. Explain the geographic and seasonal distribution of biological productivity in the world's oceans using an understanding of ocean structure and processes.
3. Evaluate an ocean-related problem or issue impacting our community or the environment using scientific reasoning based on field and/or laboratory and/or remote measurements and observations.
4. Assess the contributions of oceanography to our evolving understanding of global change and sustainability while placing the development of oceanography in its historical and cultural context.

The material in this course will be presented in a lecture/discussion format accompanied by laboratory exercises. Other educationally sound methods may be employed such as guest lectures, field trips, research papers, presentations and small group work.  

The instructor will choose from the following methods of assessment:  exams, quizzes, lab exercises, written reports, oral reports, group projects, class participation, homework assignments, and field trips.  The instructor shall detail the methods to be used to the students at the beginning of the class.  

(note: topics may be selected in any order by each instructor)  

• Explain the nature and history of oceanography as a science
• Discuss the structure and evolution of the earth’s ocean basins and coastlines.
• Discuss the mechanics of waves, currents, and tides
• Describe the major chemical and physical properties of seawater and the interaction of these properties.
• Discuss marine biology in terms of habitats and zones, life in the oceans.
• Discuss how humans impact the marine environment in terms of resources from the sea and marine pollution.
• Other topics as desired by the instructor.
