  1. KGI Esperanza Palmer Vernadsky/Faraday Rothera clicOPEN IPY 34 • 15 countries • 10 polar stations • at present 40 scientific projects climate change in cOastal environments of the Antarctic PENinsula Mean air temperature rise by 3°C since 1947 (data G. Milinevski and colleagues, Ukraine)

  2. clicOPEN IPY34 – interdisciplinary concept Changing processes: glacier retreat sediment run-off salinity changes iceberg scour frequency Driver: air warming System response species performance coastal community structure food webs Potter Cove, King George Island November 2005 (D. Abele) Potter Cove, December 2005 (foto: Ricardo Sahade)

  3. clicOPEN IPY 34 – science plan conceptual model of Antarctic Peninsula climate change effects Get signal • Use local data to feed spatial • glacier melt models • . Long term data to model past • glacier melt • local sediment discharge • Water column • snow dynamics on ice free areas • coastal sediment cores and seismic • data • Genetic diversity • Biodiversity • Trophic structure & flow • Interaction strength Terrestrial re-colonization of ice free areas • Age/size of bivalve populations • energy reserves • Critical limits (T,S, Sed Cov, O2) • Lifetime models of fitness params • Molecular stress tags

  4. clicOPEN IPY 34 – interactive programme structure workshops symposia shared tools Projects on WAP scientific stations • clicopen@lists.wdc-mare.org > 100 scientists Common sampling patterns, parameters, procedures Cross sampling between projects joint use of stations in IPY parallel experiments exchange of students and expertise between labs Steering committee (& observers) • equipment • platforms • long term measurements metadata Data management (Pangaea) historical data, regulated access to metadata within programme GIS based visualization (KGIS, etc) Process model

  5. clicOPEN IPY 34 – rules and tools and networks • Sampling grids and time scales between locations and in locations • Calibration of long term measurements • Intercalibration of methods and experimental procedures • Agreement on cross sampling • Agreements on student training • Agreement on data formate • Agreement on exchange of metadata external networks IPY Projects CCAMLR Geotraces clicOPEN German clicOPEN projects:16/41 6 -> ongoing or funded DFG projects 6 -> new proposals 4 -> financed from other sources Workshop series On WAP Climate Variability NSIDC (US, Colorado) SCAR EBA
