the coldest place on the Earths surface The transect from Prydz BayAmery Ice ShelfLambert Glacier BasinDome A is an interconnected ocean iceshelf and ice sheet system which plays a very important role in east Antarctica mass balance sea level and climate change Dome A is a little known region of the Antarctic and as it is the highest part of Antarctic ice sheet it is an ideal place for observing the earths environmental background and making new scientific findings in a range of disciplines The ice thickness at the summit of Dome A was measured as over 3000 m by the 21st Chinese National Antarctic Research Expedition CHINARE21 in the austral summer of 20042005 Snow accumulation occurs mostly by diamond dust sublimation directly from the troposphere and the oldest ice in Antarctica may be found there It is hence a potential site to reconstruct a 12M year recordof the past climate and environment With the extremely cold dry and stable air found at the summit of Dome A the area provides the best site on the Earths surface for the conduct of a wide range of astronomical observations from optical to millimetre wavelengths Beneath the ice at Dome A and near the centre of the Antarctic Continent lie the unexplored Gamburtsev subglacial mountains Study of these may contribute greatly to theoretical earth science and to understanding the geological history of Antarctica Observations along the ZhongshanDome A are important for studying ice dynamic processes and mass balance recent climate history and SolarWindMagnetosphereIonosphere coupling The ocean circulation in Prydz Bay is one of the major gyres around the Antarctic and it both affects and is affected by interaction beneath the Amery Ice Shelf Improved oceanographic studies are required of the Prydz Bay circulation its role in Southern Ocean circulation and the potential impacts of change on both physical and biological systemsWhat we will do for PANDAPANDA presents a integrated view of the Prydz BayAmeryLambert glacier basinDome A system with Chinese scientific and logistical leadership partnership coordination and cooperation for many international IPY efforts focused on this region and on Antarctica Specifically Chinese leadership and partnership as part of PANDA will support IPY through the following objectives To construct a scientific research station at the summit of Dome A supporting future scientific programs in this region nationally and internationally To establish a longterm observingmonitoring system for climate change research along the Prydz Bay Amery Ice Shelf Lambert glacier basin and Dome A transect a data sparse region of Antarctica This will involve partnerships with other meteorological glaciological and oceanographic projects during IPY To improve understanding on variability and physical processes of the ocean and sea ice in the Prydz Bay region and on their response and feedback to climate change This will involve partnership with the IPY SASSI programme To understand processes of interaction between ocean and ice shelf and their effect on the stability of the ice shelf and ice sheet To obtain a series of shallow ice cores between Zhongshan and Dome A for investigation of recent climate variability and change and a medium depth ice core at Dome A To determine site characteristics for deep ice core drilling at Dome A to potentially reconstruct a 12M year climate record This assessment during IPY will lead to new efforts to start deep ice core drilling in the summer of 20092010To assess site characteristics at Dome A for astronomical observationsTo find a suitable site for subglacial geological drilling in the Gamburtsev Mountains areaTo establish a chain of magnetometers between Zhongshan and Dome A for studying the dynamics of the solar windmagnetosphericionospheric coupling This will include comprehensive upper atmosphere observations at Zhongshan Station and will involve cooperation with the IPY solarearth coupling and magnetosphere dynamics programmesMany of these activities will leave a legacy of an infrastructure capability for international research after IPYPlanned field activities during 200720101 Prydz Bay and Amery Ice ShelfDuring austral summers of 20052006 20072008 and 20082009 oceanographic and ice shelf surveys in Prydz Bay and Amery Ice Shenlf20072008 deploy hydrographic instruments into the cavity beneath the Amery Ice Shelf in collaboration with an Australian hot water drilling project Obtain 2 years continuous measurements from the instruments2 ZhongshanDome A traverse and activities at the summit of Dome A20072008 season Glaciological observations along ZhongshanDome A transect To carry out glaciological observations and recover a 350500m ice core at the summit of Dome A Undertake an ice radar survey in the Gamburtsev sub glacial area to search the suitable site for a geological drilling Determine a deep ice core drilling site and transport a deep ice core drill to the summit of Dome A from Dome F To set up a 100 m2 building at Dome A To install several instruments for assessing astronomical conditions at Dome A Install 4 low power magnetometers along the track Establish fuel depots at Dome A and at a site 800km south of Zhongshan Station20082009 season To complete Dome A Station with a building area of 250 m2 and facilities for 10 winterers To make a pilot hole for deep ice core drilling and set up deep ice core drilling system Undertake further glaciological observations of the area Other observations20092010 season To operate the Dome A station and start deep ice core drilling there Other observation including astronomy observations etcPrevious work at ZhongshanDome A Amery Ice Shelf and Prydz Bay by CHINAREDuring the last decade CHINARE has carried out following research workFour inland traverses from the Zhongshan Station towards Dome A have been made in the summers of 19961997 1997199819981999 and 20042005 Glaciological observations were obtained and samples were obtained from shallow cores and snow pits along the route During the latest traverse the CHINARE team reached the summit of the Dome by snow mobiles A series of measurements in glaciology and meteorology were carried out and two automatic weather stations were installed in collaboration with Australia one is at the summit of the Dome and one at the midpoint of the transectGlaciological field programs have been conducted on the Amery Ice Shelf in the summers of 20022003 20032004 20042005 The major work has included ice radar surveys of ice thickness GPS measurements of ice velocity estimation of ice shelf mass balance recovery of a 296m ice core and hydrographic observations along the edge of the Amery Ice ShelfPhysical oceanography chemical oceanography marine biology and geochemistry observations in the Prydz Bay region have been carried out since 1989 A series of data have been obtainedGroundbased observations of the ionosphere imaging riometer optical aurora geomagnetic fields etc have been carried out at Zhongshan Station for more than ten years" @default.
