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 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 |
