What makes the Arctic climate system so unique is the sea ice, which influences the Arctic climate in many ways. In this Data Puzzle, students analyze a humidity dataset captured by a drone during the historic MOSAiC Arctic expedition to investigate the question, "What effect, if any, do leads (cracks in the sea ice) have on the transfer of moisture between the Arctic Ocean and atmosphere?"

Since the early 2000s, the Greenland Ice Sheet’s mass balance has been consistently negative, meaning more mass is being lost than gained. But this change in mass balance hasn’t always happened at the same rate. In this Data Puzzle, students analyze temperature, snowfall, and meltwater rate datasets to investigate the question, "What factors are contributing to changes to the Greenland Ice Sheet in recent decades?"
