Greg Wiles Introduction: Global warming and climate change will be the environmental issue to receive the most attention over this century. Understanding how and why climate changes is important for interpreting the past geologic record and evaluating contemporary climate change. After an overview of Earth's ocean-atmosphere system and energy blance, Quaternary (last 2 million years) dating methods and techniques of reconstructing past climates are actively explored through field and lab projects. Students will work with paleoclimate data sets from ocean cores, ice cores, tree-rings, lake cores and corals. Labs will included computer modeling, analysis of time series and field and lab projects extracting lake sediment cores and collecting and processing dendrochronological data. The lab work will be collaborative efforts processing sediments and tree-ring data, so you will need to work together and with your TA - Mike Krivicich. Mike is a senior geology majr who worked in Glacier Bay Alaska over the summer and at the Wooster Tree Ring Lab. He will be cooardinating lab work and in harge of lab logisitics. Preparation questions: At each class I will hand out preparation questions that should be answered for the following class. They are designed to guide the discussion for the next class AND I will occasionally collect them and they will count as one of your quizzes. Text books: We will be having various readings from a variety of texts. Paleoclimatology: Reconstructing Climate of the Quaternary (PC) by Raymond Bradley. Additional reading will be handed out in class. Goals: Climate Change is a Q (quantitative) course thus students will need to generate, manipulate and interpret quantitative data, use geologic concepts to solve problems and understand and apply scientific methodology. This course is also field and lab intensive and so students will demonstrate their ability to apply Field/Laboratory skills, Map Interpretation/Geographical Information skills, and Information Technology skills. As we will be performing original studies of lake and tree-ring proxies in the Wooster region students will be need to demonstrate independence of thought and expression. The work in this class will demonstrate integrative thinking by approaching problems through multiple approaches. Finally through writing reports and giving class presentations the students will develop their commnication skils.

Research Paper: This is a paper covering a topic of your interest in invertebrate paleontology (and not covered in class). It will be roughly 10-15 pages in length, plus illustrations. We will discuss potential topics early in the semester so that you can get started quickly. The paper is scheduled in four assignments: first you turn in a topic and a couple primary references, second is an outline with more references, third is a preliminary draft, and fourth is the final research paper itself. Be sure to use our Departmental Writing Webpage. Lab Reports: We will have fieldtrips to collect samples and tour the landscape of NE - Ohio. These are listed in the syllabus above. If you have conflicts let me know as soon as possible. We will be taking one trip when we will need to leave at 12noon and will return at 5:00 PM - this is a trip to the Byrd Polar Research Center, wher we will vistit the Ice Core Paleoclimatology Group and the Remote Sensing Group. You should purchase a yellow notebook in the bookstore or have some kind of field notebook for our work outside in the course of labs. Also for labs and trips bring your cameras and we will keep a running photo gallery for the class. This is fun to look at and the images can be used in reports and projects. Quizzes: I will give 8-10 quizzes over the course
of the semester. Occasionally I will colllect the preparation questions
as a quiz. I drop the lowest quiz grade - there are no makeup quizzes
given. Research project:You are required to choose a topic
that you will write a 6-10 page paper and present to the class during
the final lab period. This can be an analysis of materials that we
collect in the field (tree cores, sediment cores), it can be an analysis
of a dataset availablle in the Wooster Tree Ring Lab or on the web,
or it can be some other topic of interest. I do expect a written page
outlining your project and at least 5 references and a first draft
of your paper in mid November. All final papers are due on the final
day of class. Presentations: You are required to give
3 informative 10-minute Powerpoint presentations to the class. These
will be topics chosen from a sheet I han out in class and will pertain
to the broad topics of Deep Time Examples of Climate Change, Other Dating
Methods, and Climate Impact on Civilizations. These are important topics
that we can't do justice to during the course and so each of you will
present some information on them. There will be two lab projects one
tree-ring based and the other analysis of sediment cores. The schedule
of analyses if flexible because we do not have the cores in hand - we
will be sampling in September and then analyzing the material for the
remainder of the term. Some classtime will be used as lab time and vice
versa.
Teaching Assistant Mike Krivicich , a senior Geology major will be the TA for
the course. Mike took the class in Fall 2006 and will help out in labs
as well as give you a hand for logistics (powerpoint etc.) for class
presentations. Schedule Conflicts The faculty of the College has recently approved a
new policy regarding conflicts between extracurricular and academic
events. The policy reads as follows: "The College of Wooster is
an academic institution and its fundamental purpose is to stimulate
its students to reach the highest standard of intellectual achievement.
As an academic institution with this purpose, the College expects students
to give the highest priority to their academic responsibilities. When
conflicts arise between academic commitments and complementary programs
(including athletic, cultural, educational, and volunteer activities),
students, faculty, staff, and administrators all share the responsibility
of minimizing and resolving them. As a student you have the responsibility
to inform the faculty member of potential conflicts as soon as you are
aware of them, and to discuss and work with the faculty member to identify
alternative ways to fulfill your academic commitments without sacrificing
the academic integrity and rigor of the course." I have a weekly appointment schedule posted on my office
door in Scovel 119. You can also contact me via email if you have any
questions (gwiles). |
