G115 VIRTUAL FIELD TRIP #2: COASTAL EXPLORATION INTRODUCTION*

This virtual fieldtrip is actually two fieldtrips, and it takes you first to the west coast and then to the east coast to compare coastal features and processes, including wave action, beach sand source and movement, coastal bluff and dunes, and human interferences. The first fieldtrip is to the shoreline of San Diego North County in Southern California, and your trip guide is Chris Metzler, earth science professor at MiraCosta College (Fieldtrip 1). The second fieldtrip is to northeast shore of Florida, near the town of Marineland, and your trip guide is Joann Mossa, geography professor at the University of Florida (Fieldtrip 2).

ESSAY: COMPARISON OF EAST AND WEST COAST SHORELINES

Now that you have reviewed the coastal characteristics of two different locations, you will prepare a well-researched, well-written, detailed (750-1000 words) comparison of the two location. Your essay should answer the following questions:

• What two locations did you study, and what are their physical characteristics? • What did you find similar, in terms of features and processes, that occur on both East and West coast

shorelines? • What did you find significantly different between the two? What is the cause of these differences? • What human effects / interventions did you explore in this field trip, and what are the consequences of

humans on each coastline? • Which shoreline would you prefer to spend time at, and why?

Your essay should be informative and well organized. You should begin with an introduction, followed by several paragraphs that describe the physical characteristics, similarities and differences, and human effects of each coastline, a conclusion, and a reflection. You should include imagery and maps, and support your discussion with primary resources from this virtual field trip, or others that you find through additional research. Follow the tips and guidelines below when preparing a report on your chosen location:

• A minimum of 750 words and a maximum of 1000 words. This is 1-2 pages of double-spaced text. • Your essay must include a title, at least 3 subheadings, at least 3 images, and a section titled “Works Cited”. • Your descriptions should be oceanographic and scientific in nature. Use terminology from the virtual field trip

worksheet and from your textbook readings. Your descriptions should give a thorough overview of the location and all of your content must be scientific and geologic in nature. You may decide how best to do this, but your essay should be informative, and contain subheadings for each of your major topics. Consider using the topics explored on the previous page of this virtual field trip as your major ideas for the essay.

• Your description should include at least 3 graphics; one should be a map and all should be captioned and referenced. A caption tells your reader what the graphic shows. The reference tells where you found the graphic.

• At least 3 resources must be cited in MLA or APA format, both in-text and in a Works Cited section. Your essay should integrate at least three primary resources. Your resources must be cited in-text, and in a works cited section at the end of your essay.

• A reflection paragraph at the end of your essay, of no less than 250 words, should address the following questions:

o What did you learn from this virtual field trip that you did not know before? o What did you find most interesting about this virtual field trip? o Give a specific example of a time where you were able to directly apply your oceanographic knowledge during

this virtual field trip. o What other questions did this virtual field trip create in your mind? In other words, what more do you want to

know about either location studied in this field trip?

Coastal Exploration

Your essay should clearly flow from introduction to conclusion and should give your reader a comprehensive overview of the oceanographic characteristics of the two locations. Refer to your FT1 feedback for tips to improve your essay for FT2. Review the grading rubric for FT2 in Canvas Assignments to know how your work will be assessed.
