Increases in the number of people travelling to Antarctica has led to more frequent interactions between people and Antarctic wildlife, yet the effects of visitation on the animals has received limited scientific assessment. This study conducted experiments to measure the responses of incubating Adélie penguins (Pygoscelis adeliae) to controlled human approaches to determine which approach distances and approach styles caused the least disturbance to the birds. Three minimum approach distances were tested: 30, 15, and 5 m. Approaching penguins to 30 m had no measurable effect on either their behaviour or heart rate, while approaching as close as 15 m significantly elevated their heart rates above resting, undisturbed levels even though there was no behavioural indication of this response. Approaching penguins to 5 m significantly interrupted the penguins' incubation behaviour, with the potential to cause egg-cooling. Approaches to 5 m elevated heart rates above those measured when birds were undisturbed, approached to either 15 or 30 m, or exposed to ‘natural’ disturbances (that is, other penguins or south polar skuas, Catheracta maccormicki). The study also identified certain Adelie penguin behaviours that may be indicative of disturbance in response to human visitation. People visiting breeding penguins could learn to identify these behaviours, so they can monitor and modify any effects of their visit.

Exploratory activities of Norwegians, particularly those directed by Lars Christensen, off eastern Antarctica are discussed briefly in relation to contemporary Antarctic investigations and politics. The interests of Norway there and Christensen's role in establishing an understanding of the local coastline are indicated. Particular attention is paid to the landing made by Klarius Mikkelsen in the Vestfold Hills, East Antarctica, on 20 February 1935. Note is taken of the site's recent re-discovery, and the symbolic role of the landing in the national aspirations of Norway, Britain, and Australia is discussed. Mikkelsen operated under commercial and scientific interests promoted by Christensen, and his landing was, at least in published material, seen as an extension of them. However, there is a suggestion that not only had a new Norwegian land been discovered, and a landing made, but that a claim to it was at least considered. Such a claim was not appropriate given previous agreements between Norway and Britain. The site's location and environs are discussed, as are subsequent flights over it and visits made there by Australian expeditioners. The ambiguity associated with claims that Caroline Mikkelsen was the first woman to land on the Antarctic mainland is also examined. Since Mikkelsen's site was on an island within the Tryne Group, to the north of Davis station, if a mainland location is required to establish such an event, then an alternative (Scullin Monolith) is proposed; however, on this occasion four women were involved, but who was first ashore remains uncertain.

Increasing attention has been given to the protection of the polar marine environment throughout the 1990s. In the case of the Antarctic Treaty System, in addition to a number of recommendations and measures adopted at Antarctic Treaty Meetings, the 1991 Madrid Protocol on Environmental Protection to the Antarctic Treaty contains a number of measures that will enhance marine environmental protection in the Southern Ocean. In the case of the Arctic, the 1991 Arctic Environmental Protection Strategy identified marine pollution as being one of the major environmental issues in the Arctic, and a number of initiatives have since been developed to encourage the Arctic states to deal with the problem collectively and individually. However, while the collective responses of the polar states have been helpful in giving prominence to the importance of marine environmental protection in polar waters, it is the coastal states of the polar regions that need to take responsibility to give effect to these initiatives. Australia and Canada are two of the most prominent polar states in Antarctica and the Arctic, respectively. Both have large maritime claims and have also developed a range of domestic legal and policy responses to enhance marine environmental protection in the polar regions. A review is undertaken of the respective global and regional marine environmental protection regimes that apply in the polar regions, followed by a comparative analysis of the Australian and Canadian initiatives.

In 1903 Jack London (1876–1916) wrote The call of the wild. This deceptively complex adventure novel concealed the author's vision and critique of a ‘Southland’ society ensnared in a system of capitalism. To reveal the limits of capitalist constructions of knowledge and power, London took his readers from the civilised Southland of California to the frozen uncivilised ‘Northland’ of the Klondike. In this primitive Northland setting, the legacy of a Southland society that valued an individual according to economic mastery was to impede a successful response to London's exacting call of the wild. To investigate London's premise, this paper draws upon the insights of the philosopher Michel Foucault. Foucault argued that knowledge and power can be analysed in terms of region, domain, territory, and field, and his work described how institutions ‘inscribe themselves both on a material soil and within forms of discourse.’ He reasoned that ‘one is able to capture the process by which knowledge functions as a form of power and disseminates the effects of power’ through the critical apparatus of the ‘heterotopia.’ Unlike the idealised space of the Utopia, the heterotopia is a ‘real’ social and cultural space that represents, contests, or inverts other sites found within a culture. Foucault recognised the ‘ship’ as the heterotopia par excellence: ‘a floating piece of space…that exists by itself, that is closed in on itself.’ This paper argues that in London's novel the central heterotopia is the Northland sled.

This paper describes a preliminary investigation of the extent to which the normalised difference vegetation index (NDVI), derived from satellite optical imagery, can indicate the extent of damage to upland tundra (fruticose lichen and dwarf shrub) vegetation. We combine the results of a previously reported classification of Landsat multispectral scanner imagery from Kol'skiy Poluostrov, Russia, with field measurements of the biomass and spectral reflectance of tundra vegetation. The results show that the NDVI is not strongly influenced by biomass, but that differences in species composition and ground cover are significant. Other workers have concluded that vegetation indices are not useful for boreal forests. It is therefore suggested that the use of the NDVI by itself as an indicator of the state of disturbed vegetation in Arctic regions is not recommended.
