This article analyses the phenomenon of the post-Soviet Russian summer cottage, dacha, in the Arctic. We take an ethnographic comparative perspective for contributing to the refinement of our understanding of human-environment relations and urban anthropology of incomer-northerners, those with roots somewhere outside the north. Evidence from fieldwork in Murmansk Oblast, West Siberia and Sakha-Yakutia shows how for a socialist and post-socialist northern urban livelihood, the dacha has become an indispensable counterpart of life in the urban concrete housing blocks for most Russian northern inhabitants. We explore in this article the importance of dacha for northern identity of urban dwellers, by analysing spheres of individual and collective agency, freedom, attachment to place and land. We conclude that the dacha movement has filled a gap that had been left open by Soviet Arctic urbanisation: a dacha has come to stand for a human-environment relationship that gradually re-introduces rurality to urban life in the Russian Arctic so permanently that dacha places start losing their seasonal character.

The German Antarctic Receiving Station (GARS) O’Higgins at the northern tip of the Antarctic Peninsula is a dual purpose facility for earth observation and has existed for more than 20 years. It serves as a satellite ground station for payload data downlink and telecommanding of remote sensing satellites as well as a geodetic observatory for global reference systems and global change. Both applications use the same 9 m diameter radio antenna. Major outcomes of this usage are summarised in this paper.

The satellite ground station O’Higgins (OHG) is part of the global ground station network of the German Remote Sensing Data Centre (DFD) operated by the German Aerospace Centre (DLR). It was established in 1991 to provide remote sensing data downlink support within the missions of the European Remote Sensing Satellites ERS-1 and ERS-2. These missions provided valuable insights into the changes of the Antarctic ice shield. Especially after the failure of the on-board data recorder, OHG became an essential downlink station for ERS-2 real-time data transmission. Since 2010, OHG is manned during the entire year, specifically to support the TanDEM-X mission. OHG is a main dump station for payload data, monitoring and telecommanding of the German TerraSAR-X and TanDEM-X satellites.

For space geodesy and astrometry the radio antenna O’Higgins significantly improves coverage over the southern hemisphere and plays an essential role within the global Very Long Baseline Interferometry (VLBI) network. In particular the determination of the Earth Orientation Parameters (EOP) and the sky coverage of the International Celestial Reference Frame (ICRF) benefit from the location at a high southern latitude. Further, the resolution of VLBI images of active galactic nuclei (AGN), cosmic radio sources defining the ICRF, improves significantly when O’Higgins is included in the network. The various geodetic instrumentation and the long time series at O’Higgins allow a reliable determination of crustal motions. VLBI station velocities, continuous GNSS measurements and campaign-wise absolute gravity measurements consistently document a vertical rate of about 5 mm/a. This crustal uplift is interpreted as an elastic rebound due to ice loss as a consequence of the ice shelf disintegration in the Prince Gustav Channel in the late 1990s.

The outstanding location on the Antarctic continent and its year-around operation make GARS O’Higgins in future increasingly attractive for polar orbiting satellite missions and a vitally important station for the global VLBI network. Future plans call for the development of an observatory for environmentally relevant research. That means that the portfolio of the station will be expanded including the expansion of the infrastructure and the construction and operation of new scientific instruments suitable for long-term measurements and satellite ground truthing.

The Characteres Generum Plantarum of Johann Reinhold Forster and Georg Forster was the principal printed botanical work emanating from James Cook's second voyage of 1772–1775. The printing most frequently encountered is a 31.2 cm quarto dated 1776 that was probably run off in several hundred copies. A single 1775 quarto was recently discovered. Also produced was a well-known but very rare 47.5 cm folio. In this first-ever census of folio copies, two dated 1775 and 14 dated 1776 are verified; their locations, descriptions, and provenances are detailed herein.

In 1898–1899, the first American polar expedition to Zemlya Frantsa-Iosifa [Franz Josef Land], under the leadership of journalist Walter Wellman, added at least forty place names to the islands, of which many survive on modern charts. These include the main discovery of the expedition, the large island named for Scottish-born Alexander Graham Bell, then president of the National Geographic Society, along with numerous smaller islands, capes and waterways. The origins of several of these names are now confirmed using recently discovered notes in the papers of Wellman's brother and business manager, Arthur Wellman. They demonstrate the close relationship between Walter Wellman and the political, financial and scientific elites of turn-of-the-century Chicago, Illinois, Washington, D.C., and the state of Ohio, associations derived from Wellman's profession as a Washington correspondent for Chicago newspapers.

Poa annua is the only flowering plant species that has established a breeding population in the maritime Antarctic, through repeated anthropogenic introduction. The first appearance of this species in the Antarctic was observed in 1953. Annual bluegrass inhabits mainly anthropogenic sites, but recently has entered tundra communities. The functioning of P. annua in the Antarctic could not have been possible without adaptations that enable the plants to persist in the specific climatic conditions typical for this zone. Poa annua is highly adaptable to environmental stress and unstable habitats: huge phenotypic and genotypic variability, small size, plastic life cycle (life-history types ranging from annual to perennial forms). The spreading of P. annua in the Antarctic Peninsula region is a classic example of the expansion process following anthropogenic introduction of an invasive species, and illustrates the dangers to Antarctic terrestrial ecosystems that are associated with increasing human traffic.

The celebrated meeting between Captain Bellingshausen of the Imperial Russian Navy and the American sealing skipper Nathaniel Brown Palmer, off the South Shetland Islands in February 1821, has often been described by following just one or other of the two men's divergent and in some respects irreconcilable accounts. The most contentious issue is whether or not Palmer told Bellingshausen about the existence of a body of land to the south of the South Shetlands, known today as the Antarctic Peninsula. This note attempts to reach a balanced assessment of the matter by examining evidence from both sides, including several previously unconsidered items. It concludes that, although the truth will never be known with absolute certainty, the basic American account is more plausible, by the narrowest of narrow margins, than the Russian.

Captain Robert Falcon Scott has been attacked in recent decades because his Terra Nova expedition (1910–1913) had to rely on substandard Siberian ponies. Certain commentators have argued that this was Scott's fault, but the available evidence indicates that blame should rest with the buyer Cecil Meares. Additionally, archive evidence indicates that Scott specifically requested Captain Lawrence Oates to travel to Siberia to assist Meares in 1910, and that Oates refused Scott's request.

The small population of Weddell seals at Larsen Harbour, South Georgia, is isolated from the rest of the species and is unique because nearly all pups are born on land rather than on sea-ice. Observations of seals in Larsen Harbour during the breeding season are summarised. These have been infrequent until cruise ships started to visit. With often only a single observation in a year, accurate estimates of pup production are impossible but it appears that the population has decreased over the last three decades.

An account of G.R. De Wilde's contribution to Arctic photography is presented. His images from Sir Allen Young's 1875 voyage in Pandora are the earliest to be published from a British expedition, albeit in a volume that was privately printed.

The present study was conducted to determine the elemental concentration and bacterial presence in the ocean on the two sides of Brøggerhalvøya, a peninsula in Svalbard. Sediments from 25 different locations were collected and subjected to elemental analysis using inductively coupled plasma mass spectrometry (ICPMS). In total, 21 elements were analysed. The elements in their decreasing order of concentrations on the Kongsfjorden side of Brøggerhalvøya were Fe> Mn> Ba > V > Zn > Sr > Rb > Cr > Li > Ni > As > Pb > Cu > Co > Cs >Ag > Be > U> Bi >Tl > Cd while that for Forlandsendet side of Brøggerhalvøya they were Fe > Ba >Mn > V> Sr > Zn > Rb > Cr > Li > Ni > Pb > Cu > As > Co > Cs > Be > U> Tl > Bi > Cd. On the other hand, at a coastal outcrop, elements in their decreasing order of concentration were Fe > Mn > Cr > Sr > Ba > Rb > Cr > Zn > V > Rb > Ni > Li > Co > Cu > As > Pb > Cs > Be > Cd > Tl > U > Bi. AMS dates confirmed the age of outcrop sediment to be 12,496 to 42,500 BP. The crustal enrichment factor calculated for all the elements with reference to Fe values, demonstrates that the elements have derived from a crustal source. Total bacterial counts ranged from 3.30 × 105 to 3.02 × 106 per gm soil sediment. Culturable bacterial counts in these sediments were between 2.00 × 102 to 2.09 × 105 CFU's per gm. Overall comparison showed high Fe and Mn concentrations around Brøggerhalvøya, due to the presence of specific bacteria which play key roles in metal cycling and carry out biogeochemical transformations.

On 26 August 2014 as part of the SCAR open science conference held in New Zealand, a panel session and discussion forum was conducted for humanities researchers, science communicators, social scientists, archivists, curators and artists with interests in interdisciplinary research. Most of the 30 attendees were members of the SCAR history expert group and the SCAR social sciences action group.
