In mid-nineteenth century America, the Arctic adventures of Elisha Kent Kane were a common and central subject for the emerging mass media. Kane's exploits were retold through illustrated newspapers, magazines, and books, but his narratives found one of their widest audiences through the medium of the ‘panorama.’ Initially presented in fixed locations, these panoramas later traveled across the country, combining large moving canvasses with a variety of visual and theatrical effects. Kane's two Arctic expeditions were among the most popular subjects represented by panoramas in the period before the American Civil War. This article examines the history of the panorama as it reflected and shaped public interest in the Arctic regions, including earlier polar expeditions, and gives a detailed account of the Kane panoramas. Other optical media that represented Kane's exploits are also considered. Because of its broad audience and widespread appeal, the panorama, along with other emergent visual technologies, played a vital yet overlooked part, both in disseminating Kane's accomplishments and in elevating Kane to prominence and fame in the mid-nineteenth century.

This article demonstrates that, similar to the many cases of self-regulation of local commons, it is in certain conditions also possible to manage an international ocean-fishery without the use of direct coercion. The case study from the Svalbard Zone supports the argument of cooperative action theory: that a limited number of participants, rules at least partly designed by the users themselves, and a system of graduated punishment contribute to compliance with established rules. Based on observational data as well as in-depth interviews with Norwegian and Russian fishermen in the area, it seems particularly fruitful to conceive of the Norwegian Coast Guard not only as a state enforcement body in the Svalbard Zone, but its representatives also as constituent parts of a social system, a ‘seafaring community,’ in the area. When, due to jurisdictional dispute, it has been impossible to rely fully on external regulation in the area, the Coast Guard has taken upon itself the role of the mediator, admittedly representing state interests, but nevertheless aimed at achieving consensus with the fishing fleet on important regulation issues. Hence, the internal authority of this Arctic Ocean fisheries lies above all in the interface between fishermen's and inspector's arguments, and in the social relations accompanying the exchange of professional opinions.

Oriented assemblages of parallel ridges and elongated lakes are widespread on the coastal lowlands of northeast Eurasia and Arctic North America, in particular, in Alaska, Arctic Canada, and northeast Siberia. So far, only the oriented lakes have been of much scientific interest. They are believed to be formed by thermokarst in perennially frozen ice-rich sediments, while their orientation is accounted for either by impact of modern winds blowing at right angles to long axes of the lakes (when it concerns individual lakes), or by the influence of underlying bedrock structures (in the case of longitudinal and transverse alignment of lake clusters).

En masse examination of space images suggests that oriented lake-and-ridge assemblages, not the oriented lakes alone, occur in the Arctic. Hence any theory about their formation should account for the origin and orientation of the assemblages as a whole. The existing hypotheses appear inadequate for this end, so this paper proposes that the assemblages were initially created by glacial activity, that is, by ice sheets that drumlinized and tectonized their beds, as well as by sub- and proglacial meltwater, and then they were modified by thermokarst, solifluction, and aeolian processes. This assumption opens up an avenue by which all known features of oriented landforms in the Arctic can be explained. The paper suggests that the oriented landforms in Siberia and Alaska are largely signatures of a marine Arctic ice sheet that transgressed from the north, while the Baffin Island and Mackenzie Delta forms were created by the respective sectors of the Laurentide ice sheet. The oriented features discussed belong to the last Late Glacial through the Early Holocene.

Cyanobacteria and eukaryotic algae were investigated during three seasons in 18 plots established across Sverdrup Pass valley of central Ellesmere Island, 79°N, Canada. The sites differed in altitude, substratum, and other characteristics. A high species diversity totalled 136 taxa. Cyanobacteria accounted for 52 and eukaryotic algae 84 species. In both groups, numerous species did not correspond to any taxa described. However, high diversity did not always coincide with high algal abundance or biomass. On older and stable landscapes, visible crusts developed, containing mostly cyanobacteria, fungi, and other microbial components. Considerable variation in algal diversity and abundance was found among the sites. Also the southern, granitic portion of the pass was richer in green algae compared to its northern, dolomitic portion where motile cyanobacteria were more prominent. These micro-autotrophs occupied the soil profile to a depth of 7 cm. Their highest density was not at the surface but at 3–4 cm depth. One plot was contaminated by windblown copper-rich dust from a nearby outcrop and soil here was poorest in content of photosynthetic pigments, suggesting a local heavy-metal toxicity.
