  1. Ice mass balance buoy network: Coordination with DAMOCLES Jackie Richter-Menge and Don Perovich

  2. Sea ice mass balance • Simple concept • snow accumulation • snow melt • ice growth • surface melt • bottom melt • Powerful tool: • shows how changes occur • growth or decay • Difficult logistics Above Below Attributes change

  3. Readings every 1-4 hours • Data “beamed” to desktop • Results include • snow accumulation and melt • ice growth • ice surface and bottom ablation • air, ice, ocean temperature • net surface heat budget • ocean heat flux Autonomous ice mass balance buoys Almost as good as being there

  4. Sample results Thermal evolution of the ice

  5. Sea Level Pressure (hPa) Surface Air Temperature (°C) • Partner with other groups • DAMOCLES • NPEO • BGOS • IABP • Collocate with • atmosphere • ocean • Integrate with • remote sensing • models Deployment plans Collocation is the key – we love to partner

  6. Web site with all data and metadata • Easy downloads • Plus all other archiving requirements Data archiving and dissemination http://www.crrel.usace.army.mil/sid/IMB/index.htm
