For Cooper lecture on January 11 (Class 2):
1. Look through the
textbook to get a feel for the topics it covers; Anderson
2. In Chapter 2 (Geologic History of Antarctica) of the text, our emphasis will be on the last 175 m.y. (I.e., since initial Gondwana breakup). Look at the figures in Chap. 2, and briefly read p.34 (bottom) to p. 43 (middle) and p.53 (bottom) thru p.57.
For Cooper lecture on January 16 (Class 3):
Read the following parts of the Anderson textbook
· Chapter 3: pages 58-61
· Chapter 5: pages 155-185 (Ross Sea, Antarctic Peninsula). Focus on sections relating to the regional geologic setting and structural framework– we will come back to the seismic stratigraphic sections later).
For Cooper lectures on January 18 and 23 (Classes 4 & 5):
Read the following part of the Anderson textbook
· Chapter 5: pages 186–206 (Weddell Sea and other parts of the Antarctic margin). Focus on sections relating to the regional geologic setting and structural framework– we will come back to the seismic stratigraphic sections later).
Read the paper:

Knowing the geography of
International Date Line (180o Longitude)
Filchner-Ronne Ice Shelf

#2: Compilation of "pointers" to basic
marine geology information for areas around
- Assigned January 11
- Brief status report in class on January 25
- Summary table due on January 30
- Interpretation in class on February 20 (this date may change to earlier).
For your appointed area, make a table that lists the following information:
For each map, be sure to indicate:
Use the following references, and others that you can readily find:
Remember, the purpose of this exercise is mainly to learn where the data are. In the process, select one data type to delve into. Grab a sedimentology paper bathymetric map, seismic line, sedimentology paper or other source from your area and use it to prepare a short (3 minute) oral interpretation that you'll present in class on February 20 (or earlier?).
· What happens when you abruptly remove a layer of rock from a crust that is in isostatic balance (i.e., does the crust go up? or go down? or stay at the same height? and if there is a change, specifically how much change up or down will there be?)
· What happens when you abruptly add a layer of rock to a crust that is in isostatic balance (go up? down? stay the same? If a change, then how much?)
· What happens when you abruptly add a layer of ice to a crust that is in isostatic balance (go up? down? stay the same? If a change, then how much?)
Be sure to annotate the densities and thicknesses of the rock and water units that you use in your “typical” columns. Cite the reference source for your “typical” columns.
