By way of introduction, please view the power point presentation [2] on the problem of dead zones, hypoxia, eutrophication and the health of Chesapeake Bay. Then go to the assignment below to flesh out your knowledge. If you're having trouble viewing the PowerPoint, try the PDF [3]. (admittedly, this ppt is a tad aged, but the trends stand and we will discuss updated data soon!)
We think that this is a great focus for teaching about the oceans, primarily for teachers in the northeastern US, because it is "local," has food chain connections, and involves so many aspects of physical oceanography, nutrients and primary production, marine animals, environmental issues, fisheries--you name it! However, we think that oceans on both coasts experience many of the things in this presentation, so don't despair if you're on the west coast...it's great for you, too! And, there are so many resources and data sets available for students to work with.
After reading the first assigned article (Brattonetal2003 [4]), which provides an historical overview of Chesapeake Bay hypoxia on the basis of the sedimentary record, and examining the power point presentation above, answer the following questions (in a file to be uploaded to the Canvas DropBox). You may simply provide a list of elements, when appropriate. Elaborate if you like.
Please put your answers in a file and drop that in the dropbox on Canvas.
Save your document as either a Microsoft Word or PDF file in the following format:
L7_Activity1_AccessAccountID_LastName.doc (or .pages or .pdf)
For example, student Elvis Aaron Presley's file would be named "L7_Activity1_eap1_presley.doc".
See the grading rubric [8] for specifics on how this assignment will be graded.
