Attentive readers of Polar Record will have noticed that, since the issue for October 2011 (Volume 47 Issue 4), no book reviews have appeared in the journal's issues. The reason for this is simply that not only has the journal been receiving a large number of high-quality submissions in the form of articles and notes but it has also published two special themed issues in the last few months. This meant there was simply no space for book reviews and obituaries taking into consideration the space limitations of the hard copy issues. This problem is alleviated somewhat by the fact that all contributions are published online in FirstView (http://journals.cambridge.org/action/displayJournal?jid=POL) before appearing in an issue, and book reviews and obituaries published in Polar Record have been free to view online since 2010. Furthermore contributions published in FirstView may be cited in exactly the same manner as contributions published in an issue, but using the doi number rather than volume and page numbers. To rationalise the situation, it has been decided that articles and notes will continue to appear in hard copy, albeit at some remove from their publication in FirstView, while book reviews, obituaries, etc will only appear in the online version of the issue.

Radiocarbon age determinations on marine shells in lateral moraines and other deposits several kms behind the present day termini of tidewater outlet glaciers from the Prince of Wales Icefield, east-central Ellesmere Island, Nunavut, Arctic Canada, as well as tidewater glaciers from two nearby ice-caps, show that these glaciers have fluctuated considerably through the Holocene, both in length and in thickness. The terminus of Leffert Glacier, for which the best documentation is available, has been more than 20 km west of the position that it occupied in 1898–1899, when it was mapped for the first time. Leffert Glacier was much reduced in size for a period of several thousand years, between roughly 6450 and 1850 14C years BP. Other major outlet glaciers that have experienced significant fluctuations of their termini during the Holocene are: 1) MacMillan, Ekblaw and Tanquary glaciers in the Baird Inlet area, 2) Stygge Glacier and adjacent unnamed glaciers at the head of Jokel Fiord, 3) Benedict Glacier at the head of Sawyer Bay and 4) Parrish Glacier, the southernmost outlet glacier from the Agassiz Ice Cap. Of the glaciers investigated, only Alfred Newton Glacier, south of Cape Herschel, has surged during the period of field observation (1977 to 2009), and this glacier is now receding from the position attained in a surge which commenced in 1981. The terminus of Ekblaw Glacier, at the head of Baird Inlet, is now well forward of the position it occupied in 1950, when the first aerial photograph coverage was achieved.

Icy environments (glacial ice and sea ice) can be complex ecosystems, supporting a diversity of communities. In particular, the μ-environments in which bacteria and algae are found are poorly understood. One important habitat is the liquid trapped in the ice, either as veins and triple junctions inherent in the ice structure or as liquid inclusions. μ-Raman spectroscopy is an analytical tool with the potential to characterise qualitatively and quantitatively these liquid μ-environments especially with respect to molecular anions such as nitrate, sulphate, bisulphate and MSA. Using a model system for glacial ice, splat-cooled samples were prepared from aqueous solutions of these anions at varying concentrations (50–75 mM total sulphate, 30–200 mM nitrate, and 10–55 mM MSA). Concentrations of these anions in the vein liquid were measured directly and non-destructively at –15 °C using μ-Raman spectroscopy. In agreement with predicted concentrations in glacial ice veins, it was found that typical ionic concentrations in veins are quite high, with mean concentrations ranging from 0.23 M to 3.5 M depending on anion type and initial concentration. For sulphate solutions, it was also possible to measure vein pH's directly. The observed pH in these systems was extremely low, in some cases ~1. The results of these model studies as well as the implications for ice vein concentrations in natural systems of polycrystalline ice are discussed.

The roots of a British Antarctic policy can be traced, paradoxically, back to the establishment of a meteorological station by the Scottish Antarctic Expedition in the South Orkneys, in 1903, and the indifference of the British Government to its almost immediate transfer to the Argentine Government. It was from that modest physical presence upon Laurie Island that Argentina came increasingly to challenge British claims to the sovereignty of the Falkland Islands Dependencies (FID), first in the late 1920s and then more extensively in the second world war. This challenge shaped British policy for the next forty years, with further complications caused by overlapping territorial claims made by Chile and the possible territorial ambitions of the USA. Britain's eventual response, at the height of World War II, was to establish permanent occupation of Antarctica from the southern summer of 1943–1944. This occupation was given the military codename Operation Tabarin. However, it was never a military operation as such, although monitoring the activities of enemy surface raiders and submarines provided a convenient cover story, as did scientific research once the operation became public. Whilst successive parties, rich in professional scientists, considerably expanded the pre-war survey and research of the Discovery Investigations Committee, their physical occupancy of the Antarctic islands and Peninsula was essentially a political statement, whereby the Admiralty and Colonial Office (CO) strove to protect British territorial rights, whilst the Foreign Office (FO) endeavoured to minimise disruption to Britain's long-standing economic and cultural ties with Argentina, and most critically, the shipment of war-time meat supplies. In meeting that immediate need, Tabarin also provided the basis from which Britain's subsequent post-war leadership in Antarctic affairs developed.

The European Union's (EU's) intention of becoming a permanent observer in the Arctic Council and the reluctance of Arctic actors to grant it that status have made the union's aspirations in the Arctic the subject of a continuing debate. The discussion appears to be dominated by geographical considerations and the EU's gradually emerging Arctic policy. This article puts forward a different view of the EU's presence in the region, one drawing on an analysis of relevant EU competences. As a complex international actor, the EU has acquired a broad array of decision-making powers from its member states, powers that partly extend to Iceland and Norway via the EEA Agreement. Moreover, the EU has in many cases become a relevant actor in international negotiations and treaty making processes the outcomes of which are of crucial importance for the governance of the Arctic. Our argument in the third and concluding section is that only by including the EU in Arctic governance can the international community provide better prospects for the union to sensitise its policies and discourses to the Arctic realities and for other Arctic actors to understand how the union functions. This argument is supported by an analysis of the EU's restrictions on the import of seal products and the ensuing litigation.

The Northern Forum has been in existence for more than two decades. The cooperative initiatives implement through the forum allow sub-national governments from different parts of the world to improve the quality of life of northern inhabitants and to support their sustainable development. Over time, the forum has established a clear structure with self-created rules and guidelines. However, its legal status is somewhat ambiguous: it has neither fulfilled the essential criteria of an international organisation nor that of an intergovernmental cooperative body. Nevertheless, these shortcomings are not immense obstacles to the forum's ability to serve the well being of residents of the northern regions. The forum has granted membership to business organisations, as well as to sub-national governments, which is an innovative concept in international cooperation. This article examines the evolution, administrative system, and legal status of the forum along with its contribution to the development of international law. The article concludes with observations on how this unique international regional co-operation forum could be characterised under international law and whether it has any influence in creating new norms in international administrative and environmental law.

A previously unpublished four-page pamphlet by Dr. George Murray Levick R.N. (1876–1956) on the ‘Sexual habits of the Adélie penguin’ was recently rediscovered at the Natural History Museum (NHM) at Tring. It was printed in 1915 but declined for publication with the official expedition reports. The account, based upon Levick's detailed field observations at Cape Adare (71°18′S, 170°09′E) during the course of the British Antarctic (Terra Nova) Expedition 1910, commented on frequency of sexual activity, autoerotic behaviour, and seemingly aberrant behaviour of young unpaired males and females including necrophilia, sexual coercion, sexual and physical abuse of chicks, non-procreative sex and homosexual behaviour. His observations were however accurate, valid and, with the benefit of hindsight, deserving of publication. Here we publish the pamphlet in its entirety, reinterpret selected observations and comment on its significance as a forgotten work by the pioneer of research on Adélie penguin Pygoscelis adeliae (Hombron and Jacquinot 1841) biology.

We have used a combination of traditional morphological examination and molecular DNA analysis to characterise 16 moss specimens collected from the Mawson Escarpment and Clemence Massif, exposures of bedrock and glacial debris in the southern Prince Charles Mountains of East Antarctica. The nuclear ribosomal ITS region and the chloroplast rps4 gene were sequenced and compared with those of other mosses known from coastal East Antarctica. The moss specimens from the southern Prince Charles Mountains were identified as Ptychostomum pseudotriquetrum (Hedw.) D. T. Holyoak and N. Pedersen, Schistidium antarctici (Cardot) ‘L.I. Savicz & Smirnova’ and Coscinodon lawianus (J.H. Willis) Ochyra. These constitute a new record for S. antarctici in the Prince Charles Mountains, and confirm and extend southwards previous records for P. pseudotriquetrum and C. lawianus in the region.
