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 V. The access hole at MSSTS Site 1 is blasted.

PLATE VI. The current meter ready for lowering as soon as the seal is clear of the hole.

PLATE VII. Lowering the McIntyre grab.

PLATE VIII. Biota from the sea floor include sea urchins, picnogonids and a bivalve.

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

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 XVI. Professor Christoffel starting the drill motor for paleomagnetic sampling.

PLATE XVII. Peter Garden drilling a core at Beacon Heights

PLATE XVIII. Measuring dip and dip direction before removing the plug.

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 XXII. Coal seam grades up to shale cut by channel (arrow) filled with sand (top).

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.

PLATE XXVI. View across the inner crater of Mount Erebus. Four of the party at the edge indicate scale.

PLATE XXVII. Audiograms from Mount Erebus.
