'Landscapes of Exploration' Education Pack
Landscapes of Exploration February 11 – 31 March 2012 Peninsula Arts Gallery Education Pack Cover image courtesy of British Antarctic Survey Cover image: Launch of a radiosonde meteorological balloon by a scientist/meteorologist at Halley Research Station. Atmospheric scientists at Rothera and Halley Research Stations collect data about the atmosphere above Antarctica this is done by launching radiosonde meteorological balloons which have small sensors and a transmitter attached to them. The balloons are filled with helium and so rise high into the Antarctic atmosphere sampling the air and transmitting the data back to the station far below. A radiosonde meteorological balloon holds an impressive 2,000 litres of helium, giving it enough lift to climb for up to two hours. Helium is lighter than air and so causes the balloon to rise rapidly through the atmosphere, while the instruments beneath it sample all the required data and transmit the information back to the surface. - Permissions for information on radiosonde meteorological balloons kindly provided by British Antarctic Survey. For a full activity sheet on how scientists collect data from the air in Antarctica please visit the Discovering Antarctica website www.discoveringantarctica.org.uk and select resources www.discoveringantarctica.org.uk has been developed jointly by the Royal Geographical Society, with IBG0 and the British Antarctic Survey, with funding from the Foreign and Commonwealth Office.

Land-Based Tourism in Antarctica
IP (number) Agenda Item: CEP 7b, ATCM 10 Presented by: ASOC Original: English Land-Based Tourism in Antarctica 1 IP (number) Summary This paper examines the interface between commercial land based tourism and the use of national program infrastructure, as well as recent developments in land-based tourism. Eight Parties responded to a questionnaire distributed by ASOC at ATCMs XXXI and XXXII. None of the respondents reported providing any support to tourism other than free basic hospitality, and most respondents explicitly opposed the notion of Parties being involved in tourism operations. Based on these responses it is apparent that some Parties have identified two locations where commercial land based tourism takes place using infrastructure from National Antarctic Programs. All land-based tourism operations rely directly or indirectly on some form of state support, including permits, use of runways, and use of facilities and terrain adjacent to research stations. The continued improvement of land-based facilities such as runways and camps, and the broad array of land activities now available to tourists, indicate that land-based tourism is growing. If no actions are taken soon, land-based tourism may well become consolidated as a major activity in a few years. 1. Overview In 2008 ASOC submitted to XXXI ATCM IP 41, A decade of Antarctic tourism: Status, change, and actions needed. Among other issues relevant to Antarctic tourism, ASOC’s IP 41 discussed the interface between commercial land-based tourism and the activities of national Antarctic programs. The paper remarked on a disturbing lack of clarity with regard to aspects of land-based tourism – what an IAATO representative described aptly as “fogginess”.1 ASOC’s IP 41 included a table listing several facilities used to support land- based tourism, some of which were private commercial facilities and other facilities of National Antarctic programs. -
Memoria Antártica Nacional Campaña Antártica 2014-2015 Santiago Diciembre De 2015 Presentación Del Ministro De Relaciones Exteriores
Memoria Antártica Nacional Campaña Antártica 2014-2015 Santiago Diciembre de 2015 Presentación del Ministro de Relaciones Exteriores Sr. Heraldo Muñoz Valenzuela El 16 de diciembre de 2014, el Consejo de Política Antártica, que tengo el honor de presidir, reunido en Punta Arenas, entregó un mandato a las instituciones antárticas nacionales para la elaboración de una Memoria Antártica Nacional. El documento que presentamos, compilación inédita de las tareas que se desarrollan anualmente en ese continente, da cumplimiento a dicho mandato. El quehacer antártico nacional involucra a un amplio espectro de instituciones, las que destinan personas y recursos a la ejecución de las tareas que nuestra legislación les confiere. Cada una de estas entidades cumple un papel fundamental en el logro de los objetivos establecidos en la Política Antártica Nacional, documento rector de nuestros trabajos. El Ministerio de Relaciones Exteriores, en su rol de coordinador de la Política Antártica Nacional, ha enfatizado la difusión hacia la ciudadanía de la labor que las instituciones nacionales realizan en ese continente. Junto con describir de manera general las perspectivas que se abren para los intereses nacionales en este ámbito, este documento resalta los profundos vínculos históricos, geográficos y políticos que desde los inicios de nuestra historia patria nos unen con la Antártica. Al presentar esta primera Memoria Anual, es oportuno recordar el destacado papel de Chile durante las negociaciones del Tratado Antártico, instrumento internacional que cumplirá 55 años de vigencia en 2016, a través de sus delegados Marcial Mora, Enrique Gallardo y Julio Escudero; así como durante la evolución de las cuestiones antárticas en el ámbito multilateral, gracias a figuras como Oscar Pinochet de la Barra y Jorge Berguño. -

The Netherlands Polar Programme and the Dirck Gerritsz Laboratory
Earth and Life Sciences (ALW) Netherlands Polar Programme: the Dirck Gerritsz Laboratory The Netherlands Polar Programme and the Dirck Gerritsz Laboratory The Netherlands Polar Programme (NPP) is a research programme that funds Dutch scientific research into and at the polar regions. The assessment of the research proposals together with the realisation and coordination of the NPP has been assigned by the financiers to NWO, and NWO’s Division for the Earth and Life Sciences has assumed responsibility for this. The NPP has set up the Dirck Gerritsz Laboratory at the British Antarctic Survey’s Rothera Research Station in Antarctica. Netherlands Organisation for Scientific Research Definition of the problem The polar regions are very sensitive to climate change: they form the heart of the climate system. Climate change in the polar regions has major physical, ecological, social and economic consequences that extend far beyond their boundaries. Due to the worldwide atmospheric and oceanic circulation systems, changes in the polar regions are felt throughout the world. A good understanding of these changes is important for the Netherlands; for example, as a low-lying country the Netherlands is vulnerable to sea level rises. Dirck Gerritsz Laboratory at Rothera Research Station NWO has set up the Dutch mobile research facility at the British research station Rothera on the Antarctic Peninsula. With this laboratory the Netherlands has become a fully fledged research partner within international polar research. Antarctica is a unique research environment where the consequences of climate change can be clearly measured without the disruptive influences of people. NWO is collaborating on Antarctica with the British Antarctic Survey (BAS). -
Inhomogeneity of the Surface Air Temperature Record from Halley, Antarctica

KING, JOHN TURNER, STEVE COLWELL, HUA LU, ANDREW ORR, TONY PHILLIPS, a a J. SCOTT HOSKING, AND GARETH J. MARSHALL a British Antarctic Survey, Cambridge, United Kingdom (Manuscript received 25 September 2020, in final form 10 March 2021) ABSTRACT: Commencing in 1956, observations made at Halley Research Station in Antarctica provide one of the longest continuous series of near-surface temperature observations from the Antarctic continent. Since few other records of comparable length are available, the Halley record has been used extensively in studies of long-term Antarctic climate variability and change. The record does not, however, come from a single location but is a composite of observations from a sequence of seven stations, all situated on the Brunt Ice Shelf, that range from around 10 to 50 km in distance from the coast. Until now, it has generally been assumed that temperature data from all of these stations could be combined into a single composite record with no adjustment. Here, we examine this assumption of homogeneity. Application of a statistical changepoint algorithm to the composite record detects a sudden cooling associated with the move from Halley IV to Halley V station in 1992. We show that this temperature step is consistent with local temperature gradients measured by a network of automatic weather stations and with those simulated by a high-resolution atmospheric model. These temperature gradients are strongest in the coastal region and result from the onshore advection of maritime air. -
BAS Science Summaries 2018-2019 Antarctic Field Season
BAS Science Summaries 2018-2019 Antarctic field season BAS Science Summaries 2018-2019 Antarctic field season Introduction This booklet contains the project summaries of field, station and ship-based science that the British Antarctic Survey (BAS) is supporting during the forthcoming 2018/19 Antarctic field season. I think it demonstrates once again the breadth and scale of the science that BAS undertakes and supports. For more detailed information about individual projects please contact the Principal Investigators. There is no doubt that 2018/19 is another challenging field season, and it’s one in which the key focus is on the West Antarctic Ice Sheet (WAIS) and how this has changed in the past, and may change in the future. Three projects, all logistically big in their scale, are BEAMISH, Thwaites and WACSWAIN. They will advance our understanding of the fragility and complexity of the WAIS and how the ice sheets are responding to environmental change, and contributing to global sea-level rise. Please note that only the PIs and field personnel have been listed in this document. PIs appear in capitals and in brackets if they are not present on site, and Field Guides are indicated with an asterisk. Non-BAS personnel are shown in blue. A full list of non-BAS personnel and their affiliated organisations is shown in the Appendix. My thanks to the authors for their contributions, to MAGIC for the field sites map, and to Elaine Fitzcharles and Ali Massey for collating all the material together. Thanks also to members of the Communications Team for the editing and production of this handy summary. -
Accelerated Climate Changes in Weddell Sea Region of Antarctica Detected by Extreme Values Theory
atmosphere Article Accelerated Climate Changes in Weddell Sea Region of Antarctica Detected by Extreme Values Theory Giuseppe Prete 1,*, Vincenzo Capparelli 1, Fabio Lepreti 1,2 and Vincenzo Carbone 1,2 1 Department of Physics, University of Calabria, Ponte P. Bucci 31C, 87036 Rende (CS), Italy; [email protected] (V.C.); [email protected] (F.L.); vincenzo.carbone@fis.unical.it (V.C.) 2 National Institute for Astrophysics (INAF), Direzione Scientifica, 00100 Rome (RM), Italy * Correspondence: [email protected] Abstract: On 13 February 2020, The Guardian, followed by many other newspapers and websites, published the news that on 9 February 2020, Antarctic air temperatures rose to about 20.75 ◦C in a base logged at Seymour Island. This value has not yet been validated by the WMO (World Meteorological Organization), but it is not the first time that an extreme temperature was registered in these locations. The recorded temperatures have often been described as “abnormal and anomalous”, according to a statement made by scientists working at the Antarctic bases. Since polar regions have shown the most rapid rates of climate change in recent years, this abnormality is of primary interest in the context of vulnerability of the Antarctic to climate changes. Using data detected at different Antarctic bases, we investigate yearly maxima and minima of recorded temperatures, in order to establish whether they can be considered as usual extreme events or abnormal. We found evidence for disagreement with the extreme values theory, indicating accelerated climate changes in the Antarctic, that is, a local warming rate that is much faster than global averages.
