The drafting, publishing and subsequent reproduction of Edward Wilson's evocative and sinisterly premonitory poem, The Barrier Silence, is examined. It was written in October 1911 for Part 3 of the South Polar Times (SPT), Vol. 3, prepared and ‘published’ at Robert Falcon Scott's British Antarctic (Terra Nova) Expedition hut at Cape Evans, Ross Island, shortly before Wilson, Scott and three other members set off on the ill-fated South Pole journey. Wilson contributed most of the illustrative material for all three volumes of the SPT, but this poem is the only written article attributed to him, although it is possible that he was also the author of an anonymous poem. Events that may have influenced Wilson to write his poem are also considered.

Portugal has developed an active Antarctic programme over the past decade. Here, we examine Portuguese Antarctic activity using a variety of bibliometric measures, showing that Portuguese scientific output has grown substantially faster than the field as a whole, with quality remaining broadly constant. Antarctic science made up a growing percentage of overall Portuguese research, up to 0.14% of all papers in 2016—a level comparable to many other nations with well-established research programmes. Alongside this, Portugal has increasingly engaged in policy discussions and produced policy papers for Antarctic Treaty Consultative Meetings, some of which were based on Portuguese environmental science. The Antarctic Treaty reserves decision-making powers to ‘Consultative Parties’—those who have been recognised as demonstrating substantial research activity in the continent. Our data indicates that Portugal is currently the fourth most productive non-Consultative Party, and has similar or greater output than several Parties who have already attained consultative status—its publication record is similar to that of the Czech Republic, which became a Consultative Party in 2014. The rapid growth of Portugal's Antarctic research may make it well placed to consider attaining consultative status to the Antarctic Treaty in the near future.

The Netherlands Organisation for Scientific Research and the British Antarctic Survey have built a transportable laboratory facility, named the Dirck Gerritsz Laboratory, to accommodate new scientific research on and from the western Antarctic Peninsula. The design provides a flexible, modular, plug-and-play, innovative and sustainable laboratory setup. The docking station houses four 20-foot ISO standard high-cube containers, each of which contains a different laboratory. Special technological features were used to minimise the environmental impact. The four laboratory containers are flexible and can be installed and used as required, and renewed or removed when necessary. The container laboratories have provided, since opening in 2013, enhanced facilities for global climate change research through studying the community composition of phytoplankton; the ecological impact of virus-induced mortality in different phytoplankton groups; dimethylsulphide and brominated compound fluxes; and CO2 concentrations and trace elements in sea water. Transportable research laboratory facilities provide an effective and efficient approach for undertaking scientific research in challenging environments and might be the start of a new way of undertaking research, including exchanging laboratory modules between research stations in Antarctica.

This paper presents the details of lichens and mosses found on whale vertebrae substratum in the Admiralty Bay area, King George Island, Antarctica. Samples were taken in the coastal area at Hennequin Point, a relict of the Antarctic whaling era. The samples were collected from the upper surface of the whale bones found in the study area during the austral summer 2010–2011. A total of 15 lichen and two moss species were found. All species sampled are known in the Admiralty Bay area, both as pioneers and in more advanced succession stages in ice-free areas. These results suggest that the colonisation of whale bones is not new for Antarctic plants, but it is an additional substrate on which these plants can develop. A map showing the distribution of colonised bones and details of the usual substrata for the lichens and mosses found in this study are provided.

In 1758 the renowned Swedish botanist Carl Linnaeus sent his student Anton Rolandson Martin to the Arctic on-board a whaler to collect scientific specimens. He became the first Swedish scientist to sail these northern waters and to set foot on Spitsbergen. But what route did the ship take and where exactly did he land? By using a combination of geographical information in Martin's diary together with latitude and wind directions from his meteorological records the ship's voyage has been reconstructed. The whaler set course directly to the west coast of Spitsbergen and then patrolled waters from there to the eastern flank of the ice fields off Greenland. The ship then returned to Spitsbergen as the whaling season drew to an end. Martin got the chance to set foot on land only once and for just two hours. After recent field work at the presumed locality 258 years after Martin's visit, his descriptions of the islets were checked and a first-hand comparison was made between the rock sample Martin brought home and the local bedrock. The author is now confident that the landing took place on Forlandsøyane islands, situated off the southwestern coast of Prins Karls Forland.

The emperor penguin (Aptenodytes forsteri) is an iconic Antarctic species. George Robert Gray attributed the first description to Johann Reinhold Forster during James Cook's voyage of 1772–1775, attribution that persists to this day. Gray therefore honoured Forster in the emperor's scientific name—but he was almost certainly mistaken. Thaddeus von Bellingshausen in 1820 was probably the true first observer. Charles Wilkes in 1840 was next. James Clark Ross in 1841 made important observations and brought specimens home to the British Museum. Edward Wilson and others, in 1902–1903 and 1911 on the two expeditions of Robert F. Scott, discovered and investigated the first breeding colony, substantially advancing knowledge about this remarkable creature.

In 1902, the Norwegian Professor Kristian Birkeland organised an expedition to the Arctic for studies of the aurora borealis, terrestrial magnetism and cirrus clouds. He established four stations at different locations—northern Norway, Iceland, Spitsbergen and Novaya Zemlya—all equipped with a similar set of scientific instruments. Using an extended concept of a scientific instrument, it is shown here that not only the instruments themselves, but also the external equipment, buildings and camp-facilities, as well as the manual work performed by the expedition members all played a role in obtaining the final results. Further, it is shown that Birkeland's efforts in organising and funding the expedition can be seen as an instrument-making operation.

This paper examines how Antarctica has been depicted in recruitment material, and compares the expectations set up in the advertising imagery with the reality of expeditioners’ experiences. Textual analyses of advertisements and job descriptions are used to reveal dominant themes, including the trope of extremity, while interviews with those who have spent time on the ice provide reflections on the actual challenges encountered when working in Antarctica, such as boredom. Much of the popular discourse around Antarctica continues to centre on the Heroic Era (1895–1922), a time of exploration typified by men pitting themselves against nature and striding out into unchartered expanses of ice. Although modern day life on Antarctic stations differs markedly from the extreme conditions experienced by early explorers, the continent continues to be associated with notions of toughness and extremity. We argue that in some cases, advertisements may actually target the wrong audience. This has important implications for how an Antarctic station as a workplace is conceptualised, and then experienced by those who head south, with potential detrimental effects.

Captain Robert Falcon Scott's plan for the attempt to reach the South Pole during the Terra Nova Expedition was to use horses, motorised sledges and dog teams to lay depots on the Ross Ice Shelf to advance the effective starting point for the three man-hauling groups to the foot of the Beardmore Glacier. His idea was that two of the groups would turn back after two and four weeks, after depositing supplies for the final polar party to rely on during the return journey. In this paper, the logic of the mathematical ‘jeep problem’ is applied to derive the theoretically optimal points at which the support parties should have turned back in order to optimise the relationship between distance and consumption of supplies. The results show that, according to this model, Scott took both his support parties along too far, especially the last support party under Lieutenant E.R.G.R. ‘Teddy’ Evans.

The history of maritime activity in polar regions is highly dynamic. It is the record of the fortunes of men and machines driven before the winds of economic and social change, scientific discovery, technological development and world events. This paper describes the career of the Norwegian Arctic sealer Brategg during the six decades from its construction in 1932 to its destruction in 1994. Although a record of a single vessel, Brategg’s story, involving investment and bankruptcy, war service, shipwreck, and innovation and renovation in both Arctic and Antarctic waters, also serves as a model of the changing times and fortunes of the Norwegian polar fleet as a whole across the twentieth century.
