Noël, W.J. van de Berg, M.R. van den Broeke Preface The 2016 annual workshop and open forum meeting of the IASC Network on Arctic Glaciology took place in the charming Pyrenean village of Benasque, Spain. The meeting attracted 45 participants from all over the world. The IASC Cryosphere Working Group generously supported eleven young scientists to attend the meet- ing. The participants presented cutting edge science in 30 talks and 8 posters. The open forum meeting provided many ideas to initiate as a community. An overview of the meeting, especially abstracts of the presented work, can be found in this book. The activities were, as always, not limited to the conference room, but extended to the skiing slopes of Cerler, a ski resort a few km from the conference facility in Benasque. On the slopes and afterwards, the discussions related to, amongst others, science and fieldwork continued resulting in once again a succesful and informal event. I would like to thank the local organising committee; Francisco Navaro, Eva de Andrés, Cayetana Recio-Blitz, Javier Lapazaran and Jaime Otero for the excellent organisation. Furthermore, since this is the last time I write this preface as the chair of this Network, I would also like to thank Martin Sharp. Martin, I really en- joyed working with you. And finally I wish Thorben Dunse succes as my successor as chair of the IASC Network on Arctic Glaciology. Next year the meeting will take place in Maine, USA, and I hope to meet you all there.

  • "Polar Action" of Antoni Bolesław Dobrowolski in the Interwar Period
    POLISH POLAR RESEARCH 19 1-2 31-36 1998 Joanna POPIOŁEK Museum of the Earth Polish Academy of Sciences Al. Na Skarpie 27 00-488 Warszawa, POLAND "Polar Action" of Antoni Bolesław Dobrowolski in the interwar period ABSTRACT: A. B. Dobrowolski, a member of the Belgian expedition in Belgica to West Antarctica (1897-1899), after his return home became a strong supporter of Polish scientific activity in the Polar countries. His patronage - called by him the "Polar Action", was especially well marked during organization of three Polish expeditions to the Svalbard archipelago: to Bear Island during the 2nd Polar Year, 1932-33, and to Spitsbergen in 1934 and 1938. Apart from his scientific achievements in Antarctica, Dobrowolski was also widely known as an author of popular-scientific books on history of discovery and exploration in the Arctic and the Antarctic. Key words: A. B. Dobrowolski, Polish Polar activity. Introduction Apart from scientific studies and pedagogical work, one of the passions of Antoni Bolesław Dobrowolski when he had returned home from the Belgica Expedition to West Antarctica (1897-1899), was the organization of scientific research in Poland. This was first made possible when, in recognition of his great scientific achievement - the monography "Natural history of ice", he was nomi­ nated deputy-director (in 1924), then director, of the State Meteorological Survey. Considering himself responsible in Poland not only for the meteorology, but also for the geophysics at large, he devoted much time to strengthening the State Meteorological Survey. He had founded the Marine Observatory in Gdynia, the Aerological Observatory at Legionowo near Warsaw, and the Magnetic Obser­ vatory at Świder near Warsaw.

Polar Research 9(1), 21-43. The Janusfjellet Subgroup is a marine shelf to prodeltaic succession dominated by shales with subordinate siltstones and sandstones. The subgroup comprises a lower Agardhfjellet (Upper Bathonian - Berriasian) and an upper Rurikfjellet (Berriasian - Hauterivian) formation. Based on field work in central Spitsbergen the following subdivisions of the formations are proposed (units listed in ascending order). The Agardhfjellet Formation (up to 290 m thick) contains four members: Oppdalen - a fining upwards succession from conglomerates to shales; Lardyfjellet - black paper shales; Oppdalsita - grey shales with siltstones and sandstones; and SlottsmQya - grey shales and black paper shales. Within the Oppdalen Member three beds are recognised: Brentskardhaugen - phosphoritic conglomerate; Marhogda - glauconitic sandstones; and Dronbreen - siltstones and shales. The Rurikfjellet Formation (thickness up to 226 m) is composed of two members: Wimanfjellet - grey and partly silty shale sequence, containing the Myklegardfjellet Bed (of plastic clays) at its base; and Ullaberget - silty and sandy shales with siltstones and sandstones.

  • A Sedimentological Study of the De Geerdalen Formation with Focus on the Isfjorden Member and Palaeosols
    A Sedimentological Study of the De Geerdalen Formation with Focus on the Isfjorden Member and Palaeosols Turid Haugen Geology Submission date: August 2016 Supervisor: Atle Mørk, IGB Co-supervisor: Snorre Olaussen, UNIS Norwegian University of Science and Technology Department of Geology and Mineral Resources Engineering Abstract In this study sedimentological depositional environments of the Upper Triassic De Geerdalen Formation in Svalbard have been investigated. Facies and facies associations of the whole formation are presented, however the main focus has been on delta top sediments and in particular palaeosols. Special attention has been paid to the Isfjorden Member, which constitutes the uppermost part of the De Geerdalen Formation. The purpose of the study has been to identify palaeosols, and relate them to the overall depositional environments. The palaeosols have been identified by three main characteristics: roots, soil horizons and soil structure. Based on field observations an attempt to classify the palaeosols has been made. There are notable differences between brown and yellow palaeosols found in the middle and upper parts of the De Geerdalen Formation and the red and green palaeosols restricted to the Isfjorden Member. The yellow and brown palaeosols are in general immature compared to the green and red palaeosols of the Isfjorden Member. Thin sections from the Isfjorden Member on Deltaneset show excellent examples of calcrete, with clear biogenetic indicators. Distinct and alternating green and red colours might be related to fluctuations in groundwater level and reduction and oxidation of the soil profile. The palaeosols are found on floodplains, interdistributary areas and on top of proximal shoreface deposits.

  • Polish Geological Investigations of the Svalbard Archipelago 1934—1979 (An Outline)
    POLISH POLAR RESEARCH (POL. POLAR RES.) 1 2—3 217—220 1980 POLSKIE BADANIA POLARNE Polish geological investigations of the Svalbard Archipelago 1934—1979 (an outline) The Polish geological investigations of the Svalbard archipelago began in 1934 with an expedition sent to Torell Land, Spitsbergen. During that expedition, S. Z. Różycki has prepared a geological map, 1 : 50,000 scale, which covered an area of about 500 square km in the zone of Tertiary folding and its eastern foreland. Różycki's work included a study on strati- graphy of the late Paleozoic, Mesozoic, partly also Tertiary deposits of NW Torell Land, and on Alpine tectonics of that area. His paper published in 1959 contains many data important for modern palinspastic reconstruction of the Alpine fold belt of Spitsbergen. Geological investigations carried out during scientific expeditions organized in connection with the Illrd International Geophysical Year and International Geophysical Co-operation (1956—1962), and co-ordinated by K. Birkenmajer, were a direct continuation of Różycki's work from 1934. Along with geological mapping, 1 : 50,000 scale, of southern Torell Land, Wedel Jarlsberg Land and northern Sorkapp Land, altogether about 800 square kilometres (Figs. 1 and 2), K. Birkenmajer elaborated the stratigraphy and tectonics of metamorphic basement complex (Precambrian) and its early Palezoic (Cambrian and Ordovician) superstructure, parts of the Caledonian fold belt of the west coast of Spitsbergen. Birkenmajer has also distinguished a local zone of Variscan folding in inner Hornsund, and extended far to the south a detailed mapping of the Alpine fold belt of Spitsbergen. The field studies of the Precambrian metamorphic complex carried out by W.
