'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.

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). -
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. -

(Site of Special Scientific Interest No. 21) Shores of Deception Island, South Shetland Islands I
Antarctic Specially Protected Area No. 140 (Site of Special Scientific Interest No. 21) Shores of Deception Island, South Shetland Islands i. Description of Site. The Site includes 5 areas on the coast of Port Foster, Deception Island (lat 62o55’S, long 60o37’W): Area A. From the west side of Entrance Point to the west side of Collins Point on the south side of Neptune’s Bellows, and extending 500 m inland from the shore. Area B. Mid Fumarole Bay, south-west of Wensleydale Point extending for 500 m along the shore, to the line precipitous lava cliffs about 100 m inland. Area C. The ‘island’ created during the 1967 eruption in Telefon Bay, and including the low land, containing a lake, which presently joins the new ‘island’ to the main island. Area D. A strip 100 m wide extending from the high-water mark of the heated shoreline of Pendulum Cove inland to a series of gullies about 750 m inland. The area lies about 300 m south of the former Chilean station Pedro Aguirre Cerda. Area E. Kroner Lake including the land within 50 m of its shore. The boundaries of these areas of the Site are shown on the attached map. ASPA 140 Map A* ii. Reason for designation. Deception Island is exceptional because of its volcanic activity, having had major eruption 1967, 1969 and 1970. Parts of the island were completely destroyed, new areas were created, others covered by varying depths of ash. Few areas of the interior were unaffected. The island offers unique 220 opportunities to study colonization processes in an Antarctic environment (the South Sandwich Islands and Bouvetøya are at a more advanced stage of colonization while Mt. -
Accelerated Climate Changes in Weddell Sea Region of Antarctica Detected by Extreme Values Theory

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. -
