Arctic sea ice is melting, slowly but inexorably. As the ice disappears, mankind will be afforded access to regions and activities, including commercial fishing, that have been inaccessible for our entire recorded history. There is currently no regulatory body or mechanism in the high seas Arctic (also referred to as the central Arctic Ocean) to conserve and manage fish stocks, the distribution and concentration of which are poorly understood, and that might be the target of commercial fisheries. This article examines the extent and nature of ice recession in the Arctic, and its likely effect on the accessibility of central Arctic ocean fisheries to commercial exploitation. It then discusses what is known of Arctic fish stocks, both those already extant, and those that might become established or enhanced as a result of changing environmental conditions. It examines international regimes for managing fish stocks that exist either in whole or in part in global maritime commons, and existing fisheries governance mechanisms in the Arctic, and finds them to be lacking. Finally, using the Bering Sea Arctic pollock stock collapse case study as a historical analogue, this article contends that the time is now for putting in place a regional fisheries management organisation to manage and conserve central Arctic Ocean fish stocks.

The activity of intracellular proteolytic enzymes was studied in Atlantic salmon (Salmo salar L.) fingerlings (0+) after hatching from spawning nests and dispersal in the Varzuga River main stem and its Pyatka tributary (Kola Peninsula, White Sea Basin). The study focused on calcium-dependent cytosolic proteinases (µ- and m-calpains), lysosomal proteinases (cathepsins В and D) and collagenase, and determined the free/protein-bound hydroxyproline ratio, which portrays collagenolytic activity. Compared to fingerlings from the Varzuga main stem, the intracellular proteolytic enzyme activity of cysteine proteinase and collagenase was higher in fingerlings from the Pyatka tributary, where current velocities and food availability were higher. These results indicate that there is a higher rate of intracellular protein metabolism in the juveniles from this phenotypic group.

Arguably the best known scientific Antarctic venture was the British Antarctic Expedition of 1911–1913 led by Captain Robert Falcon Scott. Whilst the so-called race to the geographic South Pole with Roald Amundsen's Norwegian Antarctic expedition excited international interest, the tragic death of Scott and his returning Polar Party was a striking reminder of the hazards of operating in the south. Recent work has highlighted the possible role expedition second-in-command Lieutenant Edward ‘Teddy’ Evans played in the deaths of Scott and his men. Here I report newly discovered documents which, when placed in a wider context, raise significant questions over Evans’ behaviour during the expedition. The evidence focuses on the shortage of food at key depots, the apparently deliberate obfuscation of when Evans fell down with scurvy and the failure to pass on orders given by Scott. It is concluded that Evans actions on and off the ice can at best be described as ineffectual, at worst deliberate sabotage. Why Evans was not questioned more about these events on his return to England remains unknown.

This article examines the implementation of the principles of openness, transparency and public participation in the decision-making regarding the conditions for uranium mining in Greenland from a legal and political perspective. The time frame covers the period from the exploration for minerals before World War II to 2016–2017 when the current Greenlandic authorities prepared a licence for a project of extraction of rare earth elements and uranium in Kvanefjeld. It is shown that the issue of openness, transparency and public participation in Greenland is a longstanding issue and that the current governance does not permit public access to a draft environmental impact assessment report, impairing public participation in decision-making, and preventing the environmental consequences of these activities from being considered as a public concern. It is argued that sovereignty–its consolidation and the accession to it–has impacted the design of governance in Greenland and that the constraints put on the full implementation of the legal principles of openness, transparency and public participation in the governance of uranium mining in Greenland, amongst other factors, point to a current hybrid political and legal order in the context of a political agenda of independence.

Over the last decade claims that an Arctic ‘cold rush’ is taking place have intensified. Proponents of the argument contend that the unprecedented effects of climate change plus strong global demand for the region's natural resources are creating the conditions for a future economic boom. In both of these respects, Greenland merits particular attention. Some recent predictions suggest great riches accruing to Greenland, on account of its abundance of oil, gas and mineral deposits; as a consequence, some further argue, Greenlandic independence from Denmark is assured. In response, this article contests these arguments. For now, the natural and mineral resource sector in Greenland is tiny, and thus it is still much too soon to know whether it will even deliver the dazzling economic outcome forecast – let alone whether or not this outcome will benefit Greenland. In addition, the question of Greenlandic independence does not simply boil down to economics, but also raises various social, political, legal and strategic issues which are not easily resolvable. Consequently, Greenland's independence from Denmark is not simply a matter of time, but remains very much an open question.

The 1819–1822 overland Arctic expedition led by John Franklin was one of the most disastrous in polar history. In 1821, 20 men travelled to the Arctic Ocean by way of the Coppermine River; only nine of them survived. John Richardson's expedition journal, as published by C. Stuart Houston in 1984, is incomplete. There are no entries between 7 and 29 October 1821, even though five of the 11 deaths (some or possibly all of them by murder) occurred during this critical period. The omission of these events from the journal on which Houston's edition was based has raised suspicions that the account published in Franklin's 1823 narrative may be inaccurate. This article prints the ‘missing’ journal entries, which were located in the files of the Colonial Office, and analyses the differences between these previously unknown entries and the 1823 account.

New Zealand's Antarctic research began during the 1957/1958 International Geophysical Year. This analysis explains how and why it has evolved. There have been two phases: 1957 until 1991, when the Department of Scientific and Industrial Research and the universities were the key research organisations, and after 1991, when the publicly funded research sector became more diverse. International collaborations have been important throughout. Funding decision processes have progressed from a bottom-up curiosity-driven approach to a more complex system of regular contests. Since 1991, the focus has been on coherent strategies and the outcomes sought. Funding criteria are well-defined and contests are widely accepted as fair and transparent. Reviews and evaluations have been positive. Collaborative organisational interactions dominated decision-making during the early period. Bureaucratic politics is most evident in post-1991 organisational changes. The quality of the research strategies has improved in terms of defining outcomes sought and appropriate measures of progress towards them. However, New Zealand's Antarctic research funding is currently dispersed. It needs better coordination. Collaborative research should be emphasised in areas where New Zealand has established a strong reputation taking account of both national and global priorities if New Zealand's international research standing is to be maintained and enhanced.

The Mapping Application for Penguin Populations and Projected Dynamics (MAPPPD) is a web-based, open access, decision-support tool designed to assist scientists, non-governmental organisations and policy-makers working to meet the management objectives as set forth by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) and other components of the Antarctic Treaty System (ATS) (that is, Consultative Meetings and the ATS Committee on Environmental Protection). MAPPPD was designed specifically to complement existing efforts such as the CCAMLR Ecosystem Monitoring Program (CEMP) and the ATS site guidelines for visitors. The database underlying MAPPPD includes all publicly available (published and unpublished) count data on emperor, gentoo, Adélie and chinstrap penguins in Antarctica. Penguin population models are used to assimilate available data into estimates of abundance for each site and year. Results are easily aggregated across multiple sites to obtain abundance estimates over any user-defined area of interest. A front end web interface located at www.penguinmap.com provides free and ready access to the most recent count and modelled data, and can act as a facilitator for data transfer between scientists and Antarctic stakeholders to help inform management decisions for the continent.

The Arctic Circle Assembly has established itself as a forum for stakeholders from all around the globe to discuss Arctic affairs. This includes discussion about the future of the Arctic, impacts of climate change on local inhabitants and indigenous peoples, the natural environment and wildlife, geopolitical issues, international treaties, research projects, business-related risks and opportunities, etc. At this international conference, the interests of stakeholders vary greatly. Some want to reap the economic and strategic benefits of melting glacial and sea ice, while others want to reduce the negative impacts of climate change. It is therefore important to analyse the conference discourse in order to understand the main emphases of stakeholders, and if some express their views more loudly than others. Through greater weight of voice in the Assembly and beyond, some stakeholders have more impact on the development of a region that is of economic, geopolitical and environmental importance, not only for the northern hemisphere but globally.

The field of Security Studies traditionally focused on military threats to states' survival, however, since the end of the Cold War the concept of security has widened and individuals and communities have gradually become viewed as appropriate referent objects of security: Multifaceted challenges facing communities at the sub-state level are increasingly regarded as security threats, including their potential to cause instability for the larger society, thus affecting states’ security. In the Arctic region, a central challenge is that inhabitants are exposed to multiple non-traditional and non-military threats resulting from environmental, economic, and societal changes, which can be understood as threats to human security. We argue that a comprehensive approach to human security overlaps with the concept of societal security, and must therefore consider threats to collective identity and the essential conditions necessary for the maintenance and preservation of a distinct society. We see the human security framework as a suitable analytical tool to study the specific challenges that threaten the Arctic population, and in turn the well-being of Arctic societies. Therefore, we argue that utilising the concept of human security can promote societal security in the context of the Arctic, and in particular, its sub-regions, for example, the Barents region.

Svalbard in the European Arctic has a well-documented history of natural resource exploitation. Since its discovery in 1596, the archipelago has witnessed phases of commercial whaling, sealing, fur hunting and fishing. Scientists, trophy hunters and miners have also added to the depletion of wildlife. The magnitude, scale and speed of the hunt, however, remain largely unknown. This paper collates historical catch data of five selected species of game animal from published written and archaeological sources. These species include the bowhead whale, the Atlantic walrus, the polar bear, the Arctic fox and the Svalbard reindeer. The paper thereby aims to quantify the anthropogenic pressure on Svalbard's ecosystems over more than four centuries. This quantification is only moderately successful. The incomplete record prevents the use of this catch data as a suitable indicator of human-induced ecosystem change. To advance the state of knowledge, the paper recommends a return to the primary sources across international archives, libraries and museum collections, and outlines steps with which to arrive at the much needed time-depth in Svalbard historical ecology.

This paper presents survey measurements carried out during the 39th Polish Antarctic Expedition to the Henryk Arctowski Polish Antarctic Station in March 2015. The measurements were used to create a map on a 1:500 scale and for 3D modelling of the station buildings and vicinity. The paper also presents the geodetic control network established around the station. We discuss the issue of creating a digital elevation model for the station and its surroundings. The elevation models were generated using terrestrial laser scanning data integrated with Global Navigation Satellite System real time kinematic and tacheometric surveying. The accuracy of these models was estimated using height differences in relation to survey data. The mean height difference was 0.03 m and root mean square error was 0.05 m. Furthermore, an analysis of changes to the coastline was conducted using archival cartographic materials to assess the threat of Admiralty Bay to the station buildings. The results are important for continued scientific activity and safety at Arctowski Station, and may be useful for future research on King George Island.

In seabirds, diet and feeding methods are related to the species morphology (Croxall, Evans, & Schreiber, 1984). Species that feed on living, mobile resources rely on a fully operational beak to efficiently seize, kill and swallow their prey. This is particularly important to diving species, such as penguins, that are highly time constrained when searching for prey at depth—as air-breathing predators, penguins must maximise their feeding efficiency during their deep foraging dives (Wilson & Wilson, 1990). This is why the observation of free-ranging penguins with physical abnormalities in good body condition is so rare. Here we report a highly unusual observation of a premoult adult king penguin (Aptenodytes patagonicus Miller) in good body condition with a highly anomalous beak.

McMurdo Station, Antarctica, is a US Federal research facility operated year-round by the National Science Foundation (NSF). Its primary mission is to support scientific research, but it also provides logistical air and ground support for South Pole Station, seasonal field sites and nearby stations operated by other countries. It is the largest station in Antarctica, supporting up to 1,200 people. While McMurdo Station has a long scientific legacy, the facility also has an interesting architectural and engineering history that spans 60 years and has its antecedents in the ‘heroic age’ of exploration (1898–1916) and the Little America expeditions (1929–1958). Here, I describe the history of the built environment of McMurdo Station to clarify how it evolved from a temporary air station in the late 1950s to its current role as the flagship research facility of the US Antarctic Research Program (USAP). This historical review may provide insights that are useful as the station continues to transform and evolve, allowing it to continue its scientific mission into the 21st century.

Captain William Adams (1837–1890) was one of the exceptional whaling masters who sailed from Dundee in Scotland. This paper uses primary sources to confirm his reputation not only as a whaler but also as an adventurous explorer and wealthy businessman. He became outstandingly successful with Alexander Stephen & Sons, the Dundee shipping company that pioneered the use of auxiliary powered vessels for use in sealing in Labrador and fishing for whales in the Davis Strait and beyond. His first command was the Arctic in 1868, and his reputation was such that he was chosen by Albert Hastings Markham as his mentor in gaining experience for polar exploration. The unfortunate loss of the Arctic in Regent Sound in 1875 did no damage to this reputation and Adams was made Master of the newly built flagship of the company's fleet, the Arctic II. In 1883, by then a rich man, Adams became his own Master with the purchase of the Maud. In 1890, the vessel was returning to Dundee from Arctic waters when Captain Adams, who was accompanied by his son also William Adams (1869–1942) acting as Mate, was taken fatally ill, dying at Thurso in Caithness.

Changing environmental conditions in the Canadian Arctic are associated with an increase in marine tourism. A substantial decline in the extent of ice coverage in the summer season has resulted in greater accessibility for all categories of ships, and the tourism sector has been quick to respond to new opportunities. This increase in vessel traffic has raised significant issues for management, and particular concerns about the pleasure craft (non-commercial tourism) sector. This paper reports on research aimed at identifying change in the pleasure craft sector in Canadian Arctic waters since 1990; exploring management concerns held by stakeholders regarding changes in the sector; and, providing recommendations for government stakeholders. The paper is based on material gathered through an examination of existing data sources and stakeholder interviews (n = 22). Analysis was aimed at understanding the rapid development of the sector and potential management strategies, including research needs. Analysis reveals a dramatic increase in annual vessel numbers, particularly from 2010 onwards. Management concerns of interviewees relate to implications of this growth in four areas: visitor behaviour; services, facilities and infrastructure; control; and, planning and development. The paper concludes by describing recommendations in the areas of research needs, regulation, and strategic development.

Persistent organic pollutants (POPs) and their effects on Antarctic seabirds by using excreta as a non-destructive biomonitoring tool have received little consideration. Here we determine the levels of polychlorinated biphenyls (PCBs) and some organochlorine pesticides such as dichlorodiphenyltrichloroethanes (DDTs), hexachlorobencene (HCB), heptachlor, and endrin aldehyde in penguin excreta. Animal exposure to these environmental contaminants was determined through porphyrins in penguin droppings. Stool samples of Adélie penguin (Pygoscelis adeliae), chinstrap penguin (Pygoscelis antarctica) and gentoo penguin (Pygoscelis papua) were collected on two locations of the Antarctic Peninsula area: Base O´Higgins (Antarctic Peninsula) and Ardley Island (King George Island). Despite POPs have been banned more than three decades ago, the levels (ng g−1 ww) of PCBs (1.45-2.35), DDTs (1.33-1.76), HCB (0.51-1.70), endrin (0.48-0.71) and heptachlor (0.97-2.40) showed that these pollutants are still present in Antarctica. Porphyrin levels in excreta (4.6-6.7 nmol g−1 dw) were significantly correlated to POPs, indicating certain chemical exposure on penguin colonies that inhabit the Antarctic Peninsula area. The levels of heptachlor found in penguin guano may be affecting some biota in terrestrial sites next to nesting places. Further studies and better understanding of POPs impact on animal performance in Antarctic biota are recommended.

The third-quarter phenomenon is the dominant theoretical model to explain the psychological impacts of deployment in Antarctica on personnel. It posits that detrimental symptoms to functioning, such as negative mood, increase gradually throughout deployment and peak at the third-quarter point, regardless of overall deployment length. However, there is equivocal support for the model. The current meta-analysis included data from 21 studies (involving 1,826 participants) measuring negative mood during deployment to elucidate this discrepancy. Across studies analyses were conducted on three data types: stratified by month using repeated-measured all time points meta-analytic techniques and pre/post-deployment data for summer/winter deployment seasons. Our results did not support the proposed parameters of the third-quarter phenomenon, as negative mood did not peak at the third-quarter point (August/September) of deployment. Overall effect sizes indicated that negative mood was greater at baseline than the end of deployment for summer and winter deployment seasons. These findings have theoretical and practical implications and should be used to guide future research, assisting in the development and modification of pre-existing prevention and intervention programmes to improve well-being and functioning of personnel during Antarctic deployment.

Explorer Joseph Elzéar Bernier's famous 1909 sector claim on Melville Island is often described as a key moment in the evolution of Canada's sovereignty over the Arctic archipelago. Writers such as Yolande Dorion-Robitaille and Marjolaine Saint-Pierre have argued that Bernier was unfairly deprived of the credit he deserved for his sovereignty contributions. Alan MacEachern has recently stated in Polar Record that civil servants in the 1920s were to blame for this supposed unfair treatment. In particular, he sees Oswald Finnie of the Department of the Interior as a man who was determined at all costs to rewrite the historical record. This article contests MacEachern's depiction of Finnie and his colleagues, based on a range of primary source documents. It also emphasises the little-known but very significant role played by James White, who first placed the sector lines on an official map five years before Bernier's 1909 proclamation. The article thus clarifies the complicated relationship between White's 1904 map, Bernier's 1909 claim, an earlier sector claim made by Bernier in 1907, and the views on the sector theory held by influential members of the Canadian civil service at the time when an official sector claim was made by Ottawa in 1925.
