Outcomes and Objectives:
At the conclusion of this course, the student should be able to:
Untitled document
Upon completion of this course, students will be able to:
1.  Apply the steps of the scientific method to marine biological investigation.
2.  Apply laboratory and field techniques, including microscope use, sampling techniques, and proper note-taking, to observing, identifying, and experimenting with marine organisms and biological phenomenon.
3. Compare and contrast the cell structure and function of prokaryotic and eukaryotic cells and of plant and animal cells.
4. Compare and contrast the mechanisms of evolution and explain how they lead to the major evolutionary patterns and adaptations in the biodiversity of major marine taxa (domains, kingdoms, phyla, and class).
5.  Integrate knowledge of physical oceanography including tides, currents, waves, stratification and upwelling with biological oceanography including the distribution of nutrients and plankton in the sea.
6. Describe the concepts of zonation, ecological succession, and population growth and regulation in marine ecosystems.
7. Understand the role of biotic and/or abiotic factors in the structure of biomes, ecosystems, communities, and populations, and how humans interact with these systems.
8. Compare and contrast the physical and biological structure of selected marine communities, including distribution and trophic relationships.
9. Analyze and explain the impact of human activities on marine communities and methods used to mitigate these impacts and to restore marine habitats.
