GEOL 275: Geology and Natural History of Hawaii
SYLLABUS AND ACADEMIC REQUIREMENTS
Volcanoes in the Sea: The Geology of Hawaii, 1983, 2nd edition, G.A. MacDonald, A.T. Abbott & F.L. Peterson: University of Hawaii Press. ISBN 0-8248-0832-0.
Your grade in this course will be based on the following elements:
1) Participation and behavior. This is the most important part of a successful trip, and thus the most important part of your grade. Please note that "participation" does not mean that you simply show up for an event. It is a combination of your attitude, your contributions to the group, your willingness to help out, etc.
2) Field notebooks. You will need to keep a daily record of your observations of both geology and natural history throughout the trip. You should endeavor to make thorough observations, and also record your thoughts (of a scientific nature), speculations, hypotheses etc. You might also consider taking notes on the readings in your notebooks. You are also expected to take notes on the oral presentations (below). Field notebooks will be collected at unspecified intervals throughout the trip, so keep them up to date!
3) Oral presentation. At some point during the trip you will be responsible for making a 15-minute oral presentation to the group. You will choose your topic ahead of time--you can pick one from a list of suggested topics (attached), or you may suggest your own. I need to know before we break for the holidays what your topic is. You will have to prepare a (typed!) abstract of your presentation before we depart for Hawaii and bring 22 copies with you on the trip. When you give your presentation you will have a "white board" and colored markers to help you explain your topic. If there are complicated figures that you would like to show, make handouts of these along with the abstracts. You will be graded on the quality of your written abstract (how informative it is, how well it reflects the important points of your presentation) as well as the quality of your oral presentation (how well you inform the group, how well you understand the topic, quality of handouts and/or figures).
4) Geological reports. Your group will write 2 reports covering the geology of the islands of Kauai and Hawai'i. Your report should conform as closely as possible to the following outline:
- Table of Contents
- Introduction and General Information This section should include a colored geologic map and a map of the localities on the island that we visited. You may also include cultural information, etc.
- Volcanic Stratigraphy and Petrology Discuss each geologic unit--start with the oldest and end with the youngest Geomorphic Features.
- Geomorphology The shape of the landscape and the processes that caused it, erosion, faulting, volcanism etc.
- Other Aspects of the Island This may include geologic and environmental hazards, energy resources, and other aspects of natural history not covered elsewhere in the report.
- Human interactions with the Environment Focus here on how human activities are affected by/have affected the physical environment of the islands. Consider issues of development, availability of resources, impact on the environment, etc.
- References Cited in the Report
While the point here is to provide a general overview of the geology of the islands, you should pay special attention to the features that we have observed firsthand, and incorporate your own observations into your report to the fullest extent possible. Resources that you might use in writing your reports are your textbook, field guides and road logs, your own field books, national park info, newspaper articles, etc. Make sure when writing your report that you properly reference all sources of information (we'll discuss how to do this later).
You will be graded on your individual contribution to the report (so make sure you clearly sign your work) as well as the completeness and overall presentation made by your group. You are strongly encouraged to get together in your groups and proofread each members' work before turning it in.
5) Assorted quizzes and short essay assignments. From time to time you will be given a short assignment. These will always be announced ahead of time and will be based on our observations in the field. During our first few days in Hawaii you will have a quiz on the geography of Hawaii, so learn it!
Each of the items listed above will count approximately equally toward your final grade (quizzes together, each geologic report separately).
