During the heroic age of Antarctic exploration, nine expeditions are recorded as performing bacteriological research, but for only six were the results published and for one of these, the publication only relates to a single sample. Most of those doing the research were medically qualified though the majority of the research related to the bacteriology of snow, air, seawater and the contents of the alimentary tracts of Antarctic animals rather than clinical bacteriology. This paper discusses the research aims, the difficulties encountered and the broad results.

The papers published in this issue of Polar Record were first given at the Polar Worlds International Conference: Environmental and Social Sciences which took place in Paris in January 2011 and was organised by the GDR Mutations polaires (GDR 3062). A research group hosted by the National Centre for Scientific Research (CNRS), the GDR brings together social and environmental scientists. It has been promoting on-site data collection and interdisciplinary projects in Arctic studies for 30 years.

Legacy waste is a significant problem in Antarctica. This is particularly the case where waste generated on stations prior to the 1980s was incinerated, placed in landfill sites or disposed of at sea. Although several Australian Antarctic Division (AAD) reports from the 1980s recognise that there are contaminated sites at the abandoned Wilkes Station, there has been no systematic attempt to classify the waste or define the spatial scale of the problem, making development of strategic and systematic clean-up or preservation programmes difficult. This article reports on a project to classify the waste remaining on Clark Peninsula using categories listed in Annex III, Article 2 of the Madrid Protocol (1991). 536 sites with one or more waste items have been identified in nine categories that are based on the degree of waste hazard, recyclability, heritage value and waste management potential. Fuel drums, petroleum hydrocarbons waste and contaminated sediment occur at 38% of the sites. This waste includes around 1020 partially full fuel drums. Heritage items that illustrate expedition life at Wilkes occur at about 10% of the sites. Solid, non-combustible waste, including scrap metal, copper wire and pipe, and steel mechanical parts, occurs at 25% of the sites. Potentially hazardous or harmful waste including electrical batteries, plastics including fuel bladders, food remains, treated timber and containers containing persistent compounds occur at 28% of sites. Although hazardous substances, such as caustic soda, explosives and asbestos, occur at only 9% of the sites, these items represent significant contamination and heath issues for the sites and for visiting explorers. Any future clean-up operations will require more than just the physical removal of waste. Preservation, removal and treatment of various types of waste from Wilkes will be required as part of a multi-year, multi-strategy approach.

Agriculture in southern Greenland has a two-phase history: with the Norse, who first settled and farmed the region between 985ad and circa 1450ad, and with the recent reintroduction of sheep farming (1920ad to the present). The agricultural sector in Greenland is expected to grow over the next century as anticipated climate warming extends the length of the growing season and increases productivity. This article presents a synthesis of results from a well-dated 1500-year lake sediment record from Lake Igaliku, south Greenland (61°00′N, 45°26′W, 15m asl) that demonstrates the relative impacts of modern and Norse agricultural activities. Pollen, non-pollen palynomorphs (NPPs), sediment mass accumulation rates, diatoms and stable isotopes of nitrogen provide a comprehensive history of both phases of agriculture and their associated impacts on the landscape and adjacent lake. The initial colonisation of southern Greenland is marked by a loss of tree birch pollen, a rise in weed taxa, and an increase in coprophilous fungi and sediment accumulation rate consistent with land-use changes. The biological and chemical proxies within the lake, however, show only slight changes in diatom taxa, and a rise in δ15N. After the Norse demise and during the Little Ice Age, most of the markers return to pre-settlement conditions. However, the continuation of non-indigenous plant taxa suggests that the landscape did not completely return to a pre-disturbance state. After 1988, the character of the lake changed markedly: mesotrophic diatoms and N isotopes all reveal major shifts consistent with a trophic shift, together with a sharp rise in sediment accumulation rate. The post-1988 lake environment, affected by modern farming development, is unprecedented within the context of the last 1500 years. These results demonstrate the potential of lake sediment studies paired with archaeological investigations to reveal the relationship between climate, environment and human societies.

The flaws of the 20th century–type development ‘mega–projects’ in the circumpolar North prompt Arctic regions actively to search for alternative strategies of regional development that break away from resource–dependency and reconcile local (traditional) societies with the realities of post–Fordism and globalisation. This paper presents a study that focuses on the notion of creative capital (CC) and assesses its ability to foster economic development in Alaska. The findings suggest that some characteristics of the CC observed in Alaskan communities are similar to those found in southern regions, whereas others are distinct (but similar to those in the Canadian North). In Alaska, the synergy between cultural economy, entrepreneurship and leadership appear to be more important in characterising creative capacities than formal education. The geographical distribution of the CC is uneven and heavily clustered in economically, geographically and politically privileged northern urban centres. However, some remote regions also demonstrate considerable levels of creative potential, in particular associated with the aboriginal cultural capital (artists, crafters, etc.). A number of Alaskan regions, creative ‘hot spots’, could become places that can benefit from alternative strategies of regional development based on CC, knowledge–based and cultural economies.

The article describes investigations that highlight snow-avalanche events that have not been reported in historical records. While historical sources are most often the basis for all natural hazard and risk research, alternative methods based on geomorphic investigations are often neglected. Here, we emphasise the use of geomorphic evidence to improve our knowledge of the maximum runout distance reached by snow avalanches as well as the frequency of the events. Investigations were carried out in remote, avalanche-prone areas, where the geomorphic evidence has not been disturbed or removed. Dendrogeomorphic investigations supply annual resolved records of avalanche winters up to the age of the investigated tree stand: over 120 years in northern Iceland. The study of snow-avalanche transported debris may be used to map the extent of the potential snow-avalanche deposition zone, and offer relative dating on a secular scale; stratigraphic profiles do provide results on long timescales, but only provide relative dating. The article discusses the relevance of each method, and concludes that the combination of the three methods can improve the common risk-mitigation approach based on historical records.

On 27 January 2011, the Fort Severn Cree nation presented its perspectives on the management of wabusk (Cree term for polar bear meaning the great wandering one) or polar bear (Ursus maritimus) to the international community. The following article provides an overview of the events that have transpired since the Conférence internationale mondes polaires held in Paris, France, on 26–28 January 2011. It begins by discussing the current state of the southern Hudson Bay polar bear sub-population and describing Cree interactions with polar bears before highlighting how the Fort Severn Cree nation is developing a co-management strategy through the indigenous stewardship model for polar bear management in its traditional territory in northern Ontario, Canada.

In June 2008, the community of Pangnirtung, Nunavut, Canada experienced a rainstorm that caused structural damage to the community's bridge and extensive permafrost erosion along the Duval River. The local government characterised the event as ‘severe’ and focused their attention on the bridge collapse, in contrast to the residents, who described this particular consequence as inconvenient at worst and at best, exciting. Instead residents expressed greater concern for the permafrost erosion and the uncertainty this posed for community well-being. This article follows an 11 week anthropological field trip to Pangnirtung in the summer of 2009 and is based on 31 semi-structured interviews, two focus group discussions, and participant observation. We explore how social processes influence subjective constructions of what constitutes ‘severe’ weather in the community, and attempt to explain how such constructions lead to differing perceptions of vulnerability to ‘severe’ weather events. Contributing factors including the normalisation of threat, local beliefs regarding change and uncertainty, as well as the communication of risk information are discussed along with the different coping strategies used by government and residents in managing their perceived levels of vulnerability. The research shows the importance of understanding the role social processes play in shaping local conceptions of ‘severe’ and perceptions of vulnerability to ‘severe’ weather events. This study enhances understandings of difference within populations and adds to the growing body of literature that demonstrates the need to incorporate locally relevant indices when conducting vulnerability assessment.

Landscape and culture are among the topics that make a place attractive for tourists. Protected areas, used also for leisure purposes, represent good development opportunities for the neighbouring communities. The National Park of Greenland has adopted new regulations and leisure activities will be allowed in its area. This will represent an opportunity of increasing the tourism business in Ittoqqortoormiit, the adjacent community to the park, which is suffering from a difficult economic situation. This new use of the resources in the protected area may well serve as engine for growth and revitalization of the local economy that has a chronic lack of jobs and an important outmigration. In this article are presented some of the results of interviews done in 2009 with the Inuit of Ittoqqortoormiit regarding tourism. The goal of the project ‘Community-based tourism as an option for concrete, viable development in peripheral, remote places’ was to investigate how a small Inuit community, peripheral and remote, which has traditional subsistence activities, but low incomes and high unemployment rate, could seek economic alternatives in tourism.

Organic-rich turf mounds, fertilised with bird droppings, may develop in the lee of obstacles, including either natural or human-made structures, boulders and rock cairns in exposed mountain and sub-Arctic and Arctic periglacial/proglacial environments. These boulder-leeside deposits consist mainly of organic materials intermixed with loess trapped in baffling agents (turf), and may sometimes contain archaeological features. Certain animal and bird species may also contribute to turf-mounds by frequenting these locations. Boulders and other natural and human-made obstructions are observed to have lichen plumes, principally Xanthoria spp?, lacing the tops and downwind side of the mound and fertilised by defecating birds and mammals. Turf mounds, consisting of organic soil, can be used for both relative and chronometric age dating, the buried peat providing 14C dates for archaeological context for specific mountain sites when artefacts are recovered. In addition, field and laboratory analyses of soils provide important palaeoenvironmental and geoarchaeological information about the sites. Examples are provided from a field site in the Norra Storfjället in the Swedish SubArctic.
