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

2. Sea ice mass balance Attributes change 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

3. Autonomous ice mass balance buoys Almost as good as being there 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

4. Sample results Thermal evolution of the ice

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

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