An Arctic in Transformation
Whither Arctic Sea Ice?Using Sea Ice Data in the Classroom
• Use satellite data of sea ice to analyze trends and variability, 1979-present
• Case studies for various regions• Impacts on people/wildlife• Hudson Bay developed, others
possible• Imagery and animations for qualitative
analysis• Quantitative data for more involved analysis
• Uses ImageJ (freeware) for data/image analysis and processing
• MS Excel or other spreadsheet for further data analysis
