LIST of FIGURES and TABLES

Figure 1. The Ross Sea region showing the location of the Victoria Land basin and the area of CIROS drilling (Fig. 2) 3
Figure 2. A. Map of McMurdo Sound area, showing the main physiographic features, the location of MSSTS-1, and deep DVDP drill holes (numbers). X-Y locates the section shown in Figure 2B.
B. Geologic section across McMurdo Sound (line X-Y in Figure 2A). Offshore structure extrapolated from Iles and Dibble (1981) and Wilson et al. (1981). Faulting has been inferred from topography (Webb and Wrenn, 1982) but has in places been confirmed by field observations (P.G. Fitzgerald, pers. comm.) 4
Figure 3. Growth is sea ice thickness at CIROS 1 compared with that at nearby DVDP 15 in 1975, a normal year 5
Figure 4. Active crack in sea ice at the tip of the McMurdo Ice shelf. The crack is 10 m wide and the ice at this time (September 4, 1984) is 30 cm thick near the margin and 5 cm thick in the middle 6
Figure 5. The Longyear 44 rig and Science Hut at CIROS 2 with the Ferrar Glacier in the background 6
Figure 6. Drilling progress and the percentage of core recovered from CIROS 2 7
Figure 7. Horizontal movement of the sea ice at CIROS 1 (N.Z. Department of Lands and Survey) 7
Figure 8. Cross-section of Ferrar Valley through the CIROS 2 site, showing water depth and 3 estimates of the geometry of the valley fill 8
Figure 9. Stratigraphic column showing the major lithologic units in CIROS 2. Insets show the main facies: core width is about 45 mm, top to left 9
Figure 10. Map showing the 1984 sample sites and dominant wind directions in Granite Harbour 16
Figure 11. Minor F1 fold with curved axial surface being refolded by F2 folds. Ridge between Meserve and Hart glaciers, lower Wright Valley 20
Figure 12. Part of oblique aerial photograph TMA360-00166 (F33) looking south, showing the south wall of the Wright Valley between the Goodspeed and Hart Glaciers. Note the obvious large F2 folds visible in the valley wall. Photograph courtesy of the U.S. Geological Survey 20
Figure 13. The New Harbour and Blue Glacier areas showing localities sampled for fission-track dating this season 23
Figure 14. Model for the uplift history of the Transantarctic Mountains in the Miers Valley area based on observed apatite age variation versus elevation and the estimated depth to zero age 24page iv
Figure 15. Satellite image map of the Terra Nova Bay area. 1 - Gondwana Station, 2 - Mt Queensland camp, 3 - Priestley Glacier camp. Location of surveys in Browning Pass. R.E.S. profiles on the Campbell Glacier 28
Figure 16. Relative Gravity observed on Browning Pass in the area indicated on Figure 15 29
Figure 17. Block diagram of R.E.S. equipment 31
Figure 18. Plan view of the R.E.S. equipment mounted on skidoo and sledges 31
Figure 19. Photograph of a high resolution R.E.S. record 32
Figure 20. Example of a low resolution R.E.S. record from profile E-E′ 32
Figure 21. Block diagram of the A.A.M.T. transmitter 33
Figure 22. Location of A.A.M.T. stations 34
Figure 23. Results of A.A.M.T. sounding 35

Figure 25. Schlumberger electrode configuration 35
Figure 26. Graph of resistivity versus depth for geo-electric sounding 35
