PLATE I. A large saline water discharge (over 3000 m2) from the snout of Taylor Glacier in late October (figure just right of centre for scale).
PLATE II. Victoria Upper Glacier shows remarkably clean, debris-free marginal cliffs, ice surface and ice aprons. One medial moraine emerges from an englacial position 1000m up glacier of the margin.
PLATE III. Englacial debris in Wright Upper Glacier is characterised by clasts of coarse, angular sandstone and dolerite with a moderately well sorted sand matrix.
PLATE IV. In the northwest corner of the Labyrinth, retreat of Upper Wright Glacier has exposed previously undescribed in situ granite (dashed lines).
PLATE IX. Box core from MSSTS Site 1 showing an area of sea floor 20 × 10 cm and a thickness of 6 cm. Sediment is muddy basaltic sand. The thin white spines are sponge spicules, abundant at this site.
PLATE X. Box core from MSSTS Site 2, similar in dimensions to that above. Sediment is muddy feldspathic sand. The surface and the mottled section show signs of extensive burrowing.
PLATE XI
1. | Planktonic foraminifera Neogloboquadrina pachyderma (Ehrenberg). Scale bar 100 microns. |
2. | Benthonic foraminifera Trifarina earlandi (Parr). Scale bar 200 microns. |
3. | Radiolaria Spongodiscus cf. favus (Ehrenberg). Scale bar 40 microns. |
4. | ?Sponge spicule Scale bar 40 microns. |
5. | Ostracod Trachyleberis sp. Scale bar 200 microns. |
PLATE XII. Boulder-strewn super glacial debris on hummocky surface of dirty iceberg near Marble Point.
PLATE XIII. The debris layer on the iceberg (Plate XII) is only 30 cm thick and is mainly a sandy gravel.
PLATE XIV. Wind-blown debris caught on an iceberg trapped in the sea ice. Debris has also been deposited on the sea ice in the wind shadow (foreground).
PLATE XV. Two dirt layers (arrowed), thought to be annual, on the sea ice in Explorers Cove, New Harbour.
PLATE XIX. Annette Richards recording location and directional data. Stratigraphic level was measured with the aid of a Jacobs staff (lower right).
PLATE XX. Permian fossil soil showing prismatic jointing. Top of Weller Coal Measures, Mount Bastion.
PLATE XXI. Silicified tree stump in growth position. Light and dark bands are annual rings. Weller Coal Measures, Mount Fleming.
PLATE XXIII. Cirque basin, Mount Fleming, with dolerite dike cutting Aztec Siltstone (foreground) and Weller Coal Measures (background)
PLATE XXIV. Chilled margin between Lashly Formation sediment (below) and intruding dolerite (above). Summit sill, Mount Bastion.
PLATE XXV. Raft of Lashly Formation sandstone and mud-stone in sill of Ferrar Dolerite. South face of Mount Bastion.
