Between 1851 and 1877 Stephen Pearce (1819–1904) painted, among many other subjects, portraits of most of the distinguished 19th century British Arctic explorers. This article outlines Pearce's life, presents his most celebrated painting ‘The Arctic Council discussing a plan ofsearch for John Franklin’, and catalogues the 25 Arctic portraits held by the National Portrait Gallery. A selection of four portraits spanning the artist's working life is illustrated.

The Russian South Pole expedition carried out in 1819–1821 was an early milestone in the scientific exploration of the Antarctic. The expedition took place under the command of the Baltic German Fabian Gottlieb von Bellingshausen. Bellingshausen came from the Island of Saaremaa in Estonia. The Russian empire, and followed by the Soviet Union, did not attach much importance to Bellingshausen's expedition. It was only after World War II as the question of the Antarctic received close attention that the Bellingshausen expedition received political significance in the Soviet Union. The fact that the expedition really took place was used by the Soviet Union to claim rights to the Antarctic and also to argue for its participation in Antarctic exploration (see Tammiksaar 2007; Bulkeley 2011). In the early stages of exploration of the continent, Estonians were given the opportunity to carry out investigations there. The first Estonian research programme in the Antarctic, on noctilucent clouds, was elaborated by the astronomer Charles Villmann. Altogether some tens of Estonians have visited the southern continent performing investigations in earth sciences, atmospheric physics, hydrology and ecology of surface waters and the human influence on them. They have also carried out isotope studies of the ice sheet to reconstruct environmental conditions in the past.

The T-3 ice island case involved two trials in the United States of a Mexican-American, Mario Escamilla, for allegedly causing the death of a Negro coworker, Bennie Lightsey, on an ice island then at lat 84°45.8'N, long 106°24.4'W, on the High Seas, about 240 km north of Ellesmere Island on 16 July 1970. A federal judge in Virginia allowed Escamilla's first trail to proceed without definitively deciding on objections to jurisdiction, for he expected a ruling on this point on appeal. Issues raised by that trial are covered elsewhere (Pharand, 1971; Wilkes, 1972).

Hovercraft, or air-cushion vehicles, have been proposed several times as a means of polar transport (Mellor, 1963; Fuchs, 1964, 1966; Law, 1965; Cooper, 1965). They ride on a cushion of low pressure air which eliminates friction between the craft and the ground surface, the air being contained by flexible skirts and peripheral jets to give a substantial obstacle clearance. Their low bearing pressure (of the order of 0·01 kg/cm2) makes them potentially suitable for over-snow use. They can travel equally well over ice, snow, and water and thus can give year-round service on Arctic rivers and seas. There is no need for costly facilities such as docks or airstrips at terminals. Finally, the hard structure clearance provided by the flexible skirts should enable the vehicle to cross areas of rough sea ice or pressure ridges without a route being prepared.
