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

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
Sample results
Thermal evolution of the ice
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)
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
