  • Station Sharing in Antarctica
    IP 94 Agenda Item: ATCM 7, ATCM 10, ATCM 11, ATCM 14, CEP 5, CEP 6b, CEP 9 Presented by: ASOC Original: English Station Sharing in Antarctica 1 IP 94 Station Sharing in Antarctica Information Paper Submitted by ASOC to the XXIX ATCM (CEP Agenda Items 5, 6 and 9, ATCM Agenda Items 7, 10, 11 and 14) I. Introduction and overview As of 2005 there were at least 45 permanent stations in the Antarctic being operated by 18 countries, of which 37 were used as year-round stations.i Although there are a few examples of states sharing scientific facilities (see Appendix 1), for the most part the practice of individual states building and operating their own facilities, under their own flags, persists. This seems to be rooted in the idea that in order to become a full Antarctic Treaty Consultative Party (ATCP), one has to build a station to show seriousness of scientific purpose, although formally the ATCPs have clarified that this is not the case. The scientific mission and international scientific cooperation is nominally at the heart of the ATS,ii and through SCAR the region has a long-established scientific coordination body. It therefore seems surprising that half a century after the adoption of this remarkable Antarctic regime, we still see no truly international stations. The ‘national sovereign approach’ continues to be the principal driver of new stations. Because new stations are likely to involve relatively large impacts in areas that most likely to be near pristine, ASOC submits that this approach should be changed. In considering environmental impact analyses of proposed new station construction, the Committee on Environmental Protection (CEP) presently does not have a mandate to take into account opportunities for sharing facilities (as an alternative that would reduce impacts).

  • Application of a New Polarimetric Filter to Radarsat-2 Data of Deception Island (Antarctic Peninsula Region) for Surface Cover Characterization
    APPLICATION OF A NEW POLARIMETRIC FILTER TO RADARSAT-2 DATA OF DECEPTION ISLAND (ANTARCTIC PENINSULA REGION) FOR SURFACE COVER CHARACTERIZATION a b c a S. Guillaso ,∗ T. Schmid , J. Lopez-Mart´ ´ınez , O. D’Hondt a Technische Universitat¨ Berlin, Computer Vision and Remote Sensing, Berlin, Germany - [email protected] b CIEMAT, Madrid, Spain - [email protected] c Universidad Autonoma´ de Madrid, Spain - [email protected] KEY WORDS: SAR, Antarctica, Surface characterization, Geomorphology, Soils, Polarimetry, Speckle Filtering, Image interpretation ABSTRACT: In this paper, we describe a new approach to analyse and quantify land surface covers on Deception Island, a volcanic island located in the Northern Antarctic Peninsula region by means of fully polarimetric RADARSAT-2 (C-Band) SAR image. Data have been filtered by a new polarimetric speckle filter (PolSAR-BLF) that is based on the bilateral filter. This filter is locally adapted to the spatial structure of the image by relying on pixel similarities in both the spatial and the radiometric domains. Thereafter different polarimetric features have been extracted and selected before being geocoded. These polarimetric parameters serve as a basis for a supervised classification using the Support Vector Machine (SVM) classifier. Finally, a map of landform is generated based on the result of the SVM results. 1. INTRODUCTION Ice-free land surfaces of the Northern Antarctica Peninsula region are under the influence of freeze-thaw cycling effects on differ- ent parent materials. This is mainly due to the particular climatic conditions of the so called Maritime Antarctica and because this region is one the the fastest warming areas of the southern hemi- sphere.

  • Southern Hemisphere Mid- and High-Latitudinal AOD, CO, NO2, And
    Ahn et al. Progress in Earth and Planetary Science (2019) 6:34 Progress in Earth and https://doi.org/10.1186/s40645-019-0277-y Planetary Science RESEARCH ARTICLE Open Access Southern Hemisphere mid- and high- latitudinal AOD, CO, NO2, and HCHO: spatiotemporal patterns revealed by satellite observations Dha Hyun Ahn1, Taejin Choi2, Jhoon Kim1, Sang Seo Park3, Yun Gon Lee4, Seong-Joong Kim2 and Ja-Ho Koo1* Abstract To assess air pollution emitted in Southern Hemisphere mid-latitudes and transported to Antarctica, we investigate the climatological mean and temporal trends in aerosol optical depth (AOD), carbon monoxide (CO), nitrogen dioxide (NO2), and formaldehyde (HCHO) columns using satellite observations. Generally, all these measurements exhibit sharp peaks over and near the three nearby inhabited continents: South America, Africa, and Australia. This pattern indicates the large emission effect of anthropogenic activities and biomass burning processes. High AOD is also found over the Southern Atlantic Ocean, probably because of the sea salt production driven by strong winds. Since the pristine Antarctic atmosphere can be polluted by transport of air pollutants from the mid-latitudes, we analyze the 10-day back trajectories that arrive at Antarctic ground stations in consideration of the spatial distribution of mid-latitudinal AOD, CO, NO2, and HCHO. We find that the influence of mid-latitudinal emission differs across Antarctic regions: western Antarctic regions show relatively more back trajectories from the mid-latitudes, while the eastern Antarctic regions do not show large intrusions of mid-latitudinal air masses. Finally, we estimate the long-term trends in AOD, CO, NO2, and HCHO during the past decade (2005–2016).

  • Influences of German Science and Scientists on Melbourne Observatory
    CSIRO Publishing The Royal Society of Victoria, 127, 43–58, 2015 www.publish.csiro.au/journals/rs 10.1071/RS15004 INFLUENCES OF GERMAN SCIENCE AND SCIENTISTS ON MELBOURNE OBSERVATORY Barry a.J. Clark Astronomical Society of Victoria Inc. PO Box 1059, GPO Melbourne 3001 Correspondence: Barry Clark, [email protected] ABSTRACT: The multidisciplinary approach of Alexander von Humboldt in scientific studies of the natural world in the first half of the nineteenth century gained early and lasting acclaim. Later, given the broad scientific interests of colonial Victoria’s first Government Astronomer Robert Ellery, one could expect to find some evidence of the Humboldtian approach in the operations of Williamstown Observatory and its successor, Melbourne Observatory. On examination, and without discounting the importance of other international scientific contributions, it appears that Melbourne Observatory was indeed substantially influenced from afar by Humboldt and other German scientists, and in person by Georg Neumayer in particular. Some of the ways in which these influences acted are obvious but others are less so. Like the other Australian state observatories, in its later years Melbourne Observatory had to concentrate its diminishing resources on positional astronomy and timekeeping. Along with Sydney Observatory, it has survived almost intact to become a heritage treasure, perpetuating appreciation of its formative influences. Keywords: Melbourne Observatory, 19th century, Neumayer, German science The pioneering holistic approach of Alexander von (Geoscience Australia 2015). In 1838 Carl Friedrich Gauss Humboldt in his scientific expeditions to study the natural helped put Humboldt’s call into practice by setting up world had a substantial, lasting and international influence the Göttinger Magnetische Verein (Göttingen Magnetic on a broad range of scientific fields.

Georg Balthasar Neumayer (1826–1909) was probably the most important figure in establishing mari- time services and ocean research in Germany, after he spent several years in Australia as a young scientist. He succeeded to found the ‘Deutsche Seewarte’ in Hamburg, the predecessor of the modern BSH (Bunde- samt für Seeschifffahrt und Hydrographie—Federal Martime and Hydrographic Agency) in Hamburg and Rostock and established a wide range of maritime services by providing sailing instructions for merchant vessels.

  • Concordia: a New Permanent, International Research Support Facility High on the Antarctic Ice Cap
    “Concordia: a new permanent, international research facility high on the Antarctic ice cap” A paper presented at ISCORD2000, Hobart, Tasmania, Jan-Feb 2000 Concordia: A new permanent, international research support facility high on the Antarctic ice cap. Patrice Godon1 and Nino Cucinotta2 INTRODUCTION While there is a continuously increasing awareness of the importance of Antarctic research, the 14 million square kilometres Antarctic continent still only houses two permanent inland research stations, Amundsen-Scott and Vostok opened in Nov 1956 and Dec 1957 respectively. Recognising the unique research opportunities offered by the Antarctic Plateau, the French and Italian Antarctic programmes have agreed in 1993 to cooperate in developing a permanent research support facility at Dome C, high on the ice cap. The facility is named “Concordia”. Concordia consists of a core group of three ‘winter’ buildings flanked by a summer camp doubling up as emergency camp. All structures are on or above ground. Access is by traverse tractor trains for heavy equipment and by light ski-equipped plane for personnel and selected light cargo. Jointly operated by France and Italy, Concordia is open for research to the worldwide scientific community. Officially open for routine summer operation in Dec 1997, Concordia should be open year round from 2003 upon completion of the core winter buildings. Facilities are designed for a winter population of 16 expeditioners, nine persons conducting scientific experiments and seven support staff. Concordia pioneers an advanced concept in Antarctic operations, the integral self- elevating building, and introduces a new generation of regular, long-range Figure 1: Map showing Antarctica, Australia, New- logistic traverses.

  • Frozen Politics on a Thawing Continent
    FROZEN POLITICS ON A THAWING CONTINENT A Political Ecology Approach to Understanding Science and its Relationship to Neocolonial and Capitalist Processes in Antarctica MANON KATRINA BURBIDGE LUND UNIVERSITY MSc Human Ecology: Culture, Power and Sustainability (2 years) Supervisor: Alf Hornborg Department of Human Geography 30 ECTS Spring 2019 Abstract Despite possessing a unique relationship between humankind and the environment, and its occupation of a large proportion of the planet’s surface area, Antarctica is markedly absent from literature produced within the disciplines of human and political ecology. With no states or indigenous peoples, Antarctica is instead governed by a conglomeration of states as part of the Antarctic Treaty System, which places high values upon scientific research, peace and conservation. By connecting political ecology with neocolonial, world-systems and politically-situated science perspectives, this research addressed the question of how neocolonialism and the prospects of capital accumulation are legitimised by scientific research in Antarctica, as a result of science’s privileged position in the Treaty. Three methods were applied, namely GIS, critical-political content analysis and semi-structured interviews, which were then triangulated to create an overall case study. These methods explored the intersections between Antarctic power structures, the spatial patterns of the built environment and the discourses of six national scientific programmes, complemented by insights from eight expert interviews. This thesis constitutes an important contribution to the fields of human and political ecology, firstly by intersecting it with critical Antarctic studies, something which has not previously been attempted, but also by expanding the application of a world-systems perspective to a continent very rarely included in this field’s academia.
