This article investigates how in the Soviet Arctic researchers and indigenous communities searched and understood the mammoth before and during the Cold War. Based on a vast number of published and unpublished sources as well as interviews with scholars and reindeer herders, this article demonstrates that the mammoth, as a paleontological find fusing together features of extinct and extant species, plays an in-between role among various environmental epistemologies. The author refers to moments of interactions among these different actors as “environmental encounters”, which comprise and engage with the physical, political, social and cultural environments of the Arctic. These encounters shape the temporal stabilisations of knowledge which enable the mammoth to live its post-extinct life. This article combines approaches from environmental history and anthropology, history of science and indigenous studies showing the social vitality of a “fossil object”.

For the first time, the results of the study of the age and growth of blue hake Antimora rostrata in the waters of the Lazarev and Weddell seas (Antarctic) are presented. The longline catches were represented by fish from 42 to 69 cm in total length with weights between 420 and 2,900 g, and most individuals aged 25 to 27 years. A minimum age of 16 years was observed in a fish 47 cm long and weighing 450 g, while a maximum age of 35 years was recorded for an individual of 69 cm in length and 1,640 g in weight. The blue hake in the Lazarev and Weddell seas shows similar growth patterns to the fish from the Ross Sea and waters off Greenland.

Diplomats, officials, scientists and other actors working with the Antarctic Treaty System have not simply negotiated a range of measures for regulating human access to the region in a physical sense. They are also continually negotiating a cultural order, one in which time is central. Antarctic actors are aware that the Treaty did not once exist and may cease to exist sometime in the future. They are conscious of environmental change. Each actor tries to elevate their standing and power in the system by deploying temporal ideas and discourses in their interactions with each other: bringing their histories into negotiations, trying to control the idea of the future. This article will map three temporalities within Treaty history: first, the deployment and potency of histories and futures, their relative rhythms and lengths; second, permanence and expiration, the questions and politics of how long the Treaty should or might last; and third, the periodisation of the Treaty period, both among actors themselves and among scholars studying Antarctica.

It has long been argued that mood fluctuation patterns in Antarctic expeditioners are largely homogeneous. This research investigated mood fluctuation patterns throughout all the stages of Antarctic deployment using latent class growth analysis. Utilising advanced statistical methods, such as latent class growth analysis, can greatly help in identifying if mood fluctuation patterns experienced by Antarctic expeditioners are homogenous, and provide insight into mood fluctuation patterns, which was not possible with traditional group-based quantitative methods. Gaining a greater insight into mood fluctuation patterns in Antarctic expeditioners can assist with the development, and implementation of, strategies to assist with expeditioner well-being. The analysis was conducted on 423 expeditioner from the Australian Antarctic program between the 2005-2009 Antarctic deployment seasons. The results supported the notion that mood fluctuation patterns in expeditioners within the Australian-Antarctic programme were largely homogeneous, as a 1-class cubic latent class growth model was identified as being the optimal fit for the dataset. Theoretical and practical implications are discussed in relation to research and prevention and intervention strategies.

Soil is one of the most important constituents of an ecosystem, playing a crucial role in many environmental reactions and processes. Despite the fact that many environmental studies were conducted in the vicinity of Longyearbyen, very little is known about the physical and chemical properties as well as mineralogy of soils occurring in this town. Thus, the main aims of this study were: (1) to determine the texture, chemical properties and mineralogy of the topsoil horizons of urban soils occurring in the Longyearbyen area (Spitsbergen, Norway); and (2) to determine and explain their spatial distribution within the area of Longyearbyen. In general, the topsoils are characterised by loamy texture; acidic reaction; quite high content of total organic carbon (TOC); high content of Si, Al and Fe; and low content of K, Na, Ca, Mg and P. Quartz, K-feldspar, plagioclase, mica and chlorite are the prevailing minerals. Differences in the concentration of TOC, total nitrogen and elements in the topsoils are mainly related to the diversity of texture and mineralogy of the local parent material and the development of vegetation cover. The results indicate that topsoils in Longyearbyen are characterised by the natural properties and are not strongly transformed by human activity. However, pollution of soil with trace elements related to coal mining should be checked.

Although archaeological studies focusing on 19th-century sealing have been performed over the past 30 years, its history and sites have traditionally had low visibility in Antarctic narratives and the Antarctic Treaty System policymaking on heritage. Researchers face the challenge of increasing the visibility of sealers’ history and public awareness of the importance of conserving the oldest sites of Antarctica. In this paper, we propose that identifying patterns of tourism activity in the South Shetland Islands, specifically in their temporal and spatial dimensions, could help protect these sites and engage visitors with the early history of Antarctica. Data collected by the International Association of Antarctica Tour Operators were used to calculate landing point usage trends over time and the frequency of passenger landings from 2003–2004 to 2015–2016. We defined six different visitation patterns with temporal tendencies of passenger landings that varied from increasing, constant, or decreasing trends over time, differing in the magnitude and intensity of visitation. This information was used to assess the situation of particular sites located in the vicinity of tourism landing points. We set priorities for their conservation and management decisions and highlighted their relative potential to engage visitors with the stories of 19th-century sealing in Antarctica.

A lasting legacy of the International Polar Year (IPY) 2007–2008 was the promotion of the Permafrost Young Researchers Network (PYRN), initially an IPY outreach and education activity by the International Permafrost Association (IPA). With the momentum of IPY, PYRN developed into a thriving network that still connects young permafrost scientists, engineers, and researchers from other disciplines. This research note summarises (1) PYRN’s development since 2005 and the IPY’s role, (2) the first 2015 PYRN census and survey results, and (3) PYRN’s future plans to improve international and interdisciplinary exchange between young researchers. The review concludes that PYRN is an established network within the polar research community that has continually developed since 2005. PYRN’s successful activities were largely fostered by IPY. With >200 of the 1200 registered members active and engaged, PYRN is capitalising on the availability of social media tools and rising to meet environmental challenges while maintaining its role as a successful network honouring the legacy of IPY.

Though presidential personality and preferences heavily influence US Arctic policy, climate change and the perceived threat to US interests posed by rising international engagement in the north among great powers such as Russia and China are increasingly impacting US policy in the region. Recognising that these trends are likely to persist into the future, it is important to understand the US Arctic policymaking apparatus, how geopolitical and environmental factors affect the creation and implementation of such policies through the presidency and how the resulting presidential policies may impact US leadership in the region for years to come. Consequently, this article examines how the distinct styles and preferences of Presidents Obama and Trump interact with growing climate change and defence challenges in the region within the US Arctic policymaking process. We illustrate this interaction through examples at both domestic and international policy levels and then place it in the larger context of the differing presidential approaches to institutionalisation when setting policy. Ultimately, we conclude that not only do presidential priorities regarding climate change, rising international engagement, and institutionalisation critically influence Arctic policymaking, but how a future president views these issues will heavily impact the direction of policies affecting the region.

Are similarities of temperature, snow and ice cover, and (certain) marine mammals sufficient to warrant both polar regions being considered a single object of study or governance? We argue that their treatment as a unit is an invitation to examine the motivations behind the choice to be polar rather than Arctic or Antarctic. For individuals such as James Clerk Ross or Roald Amundsen, logistical requirements and analogous goals facilitated careers spanning both the Arctic and the Antarctic. This trend continued through the 20th century as individual scientists studying phenomena such as glaciers, sea ice, or aurora defined their research as “polar” in nature. Organisations such as the Scott Polar Research Institute and Norwegian Polar Institute could draw on traditions of national exploration in both polar regions, while the Arctic and Antarctic Research Institute in St. Petersburg gained its southern mandate with the importance of the International Geophysical Year. By comparison, neither the Arctic Institute in Copenhagen nor the Argentine Antarctic Institute felt any need to become polar. The creation of polar identity is ultimately a matter of geopolitics, of the value states see in instruments and symbols that speak to polar rather than Arctic or Antarctic interests. In cases such as Finland’s icebreaker industry, a technological capability justified Antarctic interest even without any national research tradition. We conclude by asking whether there is anything more natural about the polar regions than there is about the concept of a “tripolar” world in which the high alpine regions form a natural unit along with the Arctic and Antarctic.

This article compares Russian–Western cooperation in the Arctic and Space, with a focus on why cooperation continued after the 2014 annexation of Crimea. On the basis of this comparative approach, continued cooperation is linked to the following factors: (1) the Arctic and Space are remote and extreme environments; (2) they are militarised but not substantially weaponised; (3) they both suffer from ‘tragedies of the commons’; (4) Arctic and Space-faring states engage in risk management through international law-making; (5) Arctic and Space relations rely on consensus decision-making; (6) Arctic and Space relations rely on soft law; (7) Arctic states and Space-faring states interact within a situation of ‘complex interdependence’; (8) Russia and the United States are resisting greater Chinese involvement in these regions. The article concludes with the following contribution to international relations theory: The more that states need to cooperate in a particular region or issue-area, and the more they become accustomed to doing so, the more resilient that cooperation will become to tensions and breakdowns in other regions and issue-areas. This phenomenon can be termed ‘complex and resilient interdependence’, to signify that complex independence is more than a description. It can, sometimes, affect the course of state-to-state relations.

Polar Educators International (PEI) is a volunteer-based organization designed to build collaborative relationships between educators and polar researchers. Founded in 2012, PEI was created out of the networks formed during the International Polar Year 2007–2008. This paper explores PEI’s first five years (2012–17) of successes, challenges and opportunities that have led to the creation of an organization with over 1,500 members. Using a ‘level of participation’ framework for communities of practice, we examine the evolution of this educator-researcher network and focus on two key questions: 1) who has PEI reached and served over this time?, and 2) what are barriers to participation? Barriers include sustained engagement with researchers and establishing value within institutional frameworks that generally undervalue activities referred to as ‘education and outreach’ (EOC). EOC activities continue to be perceived as extra-curricular in both educator and researcher communities. Working to deepen collaboration with polar researchers and targeting a greater diversity of PEI’s membership to fill core leadership functions should be future areas of focus for PEI as it looks to continue to shape polar EOC. Advancing and enhancing polar EOC extends well beyond PEI and should be a priority for the broader polar science and education communities.

Daily rhythms enable organisms to adapt to daily fluctuations in environmental factors. Do organisms still exhibit 24-h rhythms when living in habitats without obvious daily cycles in external signals? To answer this question, we measured the heart rates of six Adélie penguin (Pygoscelis adeliae) chicks on Inexpressible Island during the polar day between 15 and 21 January 2019. Averaged heart rates were between 186 and 233 beats/min for individual chicks. Both fast Fourier transformation and autocorrelation were employed to assess the daily rhythmicity. Based on fast Fourier transformation, a significant contribution of daily rhythm in heart rate variation was found only in one individual. Small effect size of significant autocorrelation coefficients was found in two individuals, while there was no significant autocorrelation coefficient for 24-h time lag in four other individuals. In summary, no prevailing daily rhythm of heart rate was found in these Adélie penguin chicks. We propose that the lack of daily rhythm in Adélie penguin chicks could be an adaptation to the local environment in the polar regions, but that the adaptive value thereof remains to be investigated.

Recent research suggests that the members of the 1897 Andrée balloon expedition could have survived if they had marched towards the depot at Seven Islands instead of the Cape Flora depot after the forced landing at 82°56’N 29°52’E, and furthermore, that they reasonably should have done so given what they knew about the ice drift in the area. This paper comprises an analysis of the expedition’s depots based on a review of original sources, and the results elucidate Andrée’s initial decision to march towards Cape Flora. The Seven Island depot was not yet laid when Andrée departed in his balloon, and the information he had at the time indicated that it was highly uncertain that depot could be laid at all. Moreover, he knew it might be difficult to find the depot even if it had been laid since no exact position for it could be determined in advance. If he arrived at the Seven Islands without being able to obtain supplies there, Andrée knew he would have to continue all the way to Nordenskiöld’s old hut in Mossel Bay. Cape Flora, on the other hand, was certain to offer both supplies and shelter.

Professional scientist-geographer Erich von Drygalski led the first German expedition to Antarctica in 1901–1903. The expedition saw itself as purely scientific, which turned out to be at odds with the expectations of Imperial Germany at the time. It was one of the first to use photography extensively and effectively to document and record scientific activities and to shape the public’s image of the work that was being done in this remote and unknown part of the world. Ice was the leitmotif of Drygalski’s life. He had prior experience in the Arctic, and the year spent in Antarctica confirmed his nuanced way of viewing the ice: on the one hand, and foremost, scholarly and objective, while still appreciating its aesthetic qualities; on the other, infused with feelings of human vulnerability. Using discourse analysis, this article examines Drygalski’s published work and photographs he chose to illustrate it, in order to investigate what the ice meant to him. In his writings, it was the scholarly, objective attitude which predominated and this may have contributed to the generally lacklustre reception of his Antarctic achievements. The photographs he chose to illustrate his published work, however, were many and varied, often capturing the awe-inspiring beauty of the ice and contributing to good sales of his narrative of the South Polar Expedition.

The 1959 Antarctic Treaty made Antarctica the world’s first and only demilitarised continent, the world’s first denuclearised zone, and pioneered a comprehensive inspections system. This article explores Antarctic arms control as past precedent. It finds that the United States, which spearheaded the Antarctic Treaty negotiations, initially rationalised arms control in Antarctica as an isolated endeavour. Yet its potential elsewhere quickly appealed to various officials involved in the treaty negotiations and aligned with public perception. Subsequent initiatives for arms control took broad inspiration from the Antarctic Treaty, but regional differences limited specific adaptations.

Barton Peninsula is an ice-free area located in the southwest corner of King George Island (South Shetland Islands, Antarctica). Following the Last Glacial Maximum, several geomorphological features developed in newly exposed ice-free terrain and their distribution provide insights about past environmental evolution of the area. Three moraine systems are indicative of three main glacial phases within the long-term glacial retreat, which also favoured the development of numerous lakes. Five of these lakes were cored to understand in greater detail the pattern of deglaciation through the study of lacustrine records. Radiocarbon dates from basal lacustrine sediments enabled the reconstruction of the chronology of Holocene glacial retreat. Tephra layers present in lake sediments provided additional independent age constraints on environmental changes based on geochemical and geochronological correlation with Deception Island-derived tephra. Shrinking of the Collins Glacier exposed the southern coastal fringe of Barton Peninsula at 8 cal ky BP. After a period of relative stability during the mid-Holocene, the ice cap started retreating northwards after 3.7 cal ky BP, confining some glaciers within valleys as shown by moraine systems. Lake sediments confirm a period of relative glacial stability during the last 2.4 cal ky BP.

The paucity of the extant written record left by the Third Franklin Expedition (1845−1848) has presented challenges to the efforts of generations of searchers and scholars. Additionally, it has underscored the reliance of Western culture on written records when establishing narratives and understanding events. This paper explores the sparse written records of the expedition in the context of their contextualisation over the years within an ersatz Franklin archive which includes a variety of discourses and documentary intents. By situating the Franklin records within an archival context, it is possible to reconsider these materials as part of a collection while also examining the ways in which they stand on their own by virtue of the (sometimes unknowable) circumstances of their creation, circulation, and preservation. Combining this archival approach with Derrida’s notion of hauntology, this paper analyses the written records of the Third Franklin Expedition as an ephemeral, and ultimately inscrutable, representation of a vanished expedition.

In 1942, the British government created the Falkland Islands Dependencies Survey (FIDS) to enforce sovereignty over the Antarctic Peninsula. The small groups of men who worked for the Survey called themselves Fids. During the late 1950s when Antarctic sovereignty was being hotly debated and worked out by national governments, Fids serving at British bases criticised the British government’s use of science as a bargaining chip. Using in-house magazines written and printed at FIDS bases and oral histories, this article examines how Fids viewed Antarctic politics and how those events influenced daily life at bases on the Peninsula.
