This guide provides instructions for educators on how to use sea ice data in the classroom. The data, from the National Snow and Ice Data Center (NSIDC), describe sea ice concentration and extent of coverage. Scientists use it to monitor changes in the concentration and coverage of ice in polar regions and to compare changes over time, such as loss of extent. Topics include temporal trends in sea ...

This activity helps students to understand the many roles that polar sea ice plays in the systems that maintain our planet, by first helping them to understand the process of the formation of ice in oceanic regimes. Students will use an inquiry based lab experience relating salt content to the ability of water to freeze in order to begin this study. Specifically, they will design an experiment to ...

This site presents average ice conditions estimated using satellite passive microwave data for the most recent month available, as well as snapshots of trends and anomalies that compare these recent conditions with the mean for the month. Full description.

In this chapter, users take the role of students from a small town in Colorado, who team up with students from the town of Churchill, Manitoba, to explore changing sea ice conditions in the Arctic. Together they examine an animation that shows 30 years of satellite images to see how the extent of sea ice in the Arctic has diminished over time. The chapter storyline is built around the real-life case ... Full description.

This dataset, available on CD-ROM, features remotely sensed images of polar sea-ice concentration with elevation and bathymetry. It is intended for paleoclimate research, specifically for estimations of average seasonal variation in sea-ice concentration in the modern polar oceans, and ultimately, to constrain general circulation models of climate change. The dataset, produced by by the National Snow ... Full description.

This animation shows the global advance and retreat of daily snow cover along with daily sea ice surface temperature over Europe from September 2002 through May 2003. The snow cover was measured by the MODIS instrument on the Terra satellite, while the sea ice surface temperature was measured by the MODIS instrument on the Aqua satellite. Since these instruments cannot take measurements through clouds, ... Full description.

This animation shows the global advance and retreat of daily snow cover along with daily sea ice surface temperature over Asia from September 2002 through May 2003. The snow cover was measured by the MODIS instrument on the Terra satellite, while the sea ice surface temperature was measured by the MODIS instrument on the Aqua satellite. Since these instruments cannot take measurements through clouds, ... Full description.

This animation shows the global advance and retreat of daily snow cover along with daily sea ice surface temperature over the Northern Hemisphere from September 2002 through May 2003. The snow cover was measured by the MODIS instrument on the Terra satellite, while the sea ice surface temperature was measured by the MODIS instrument on the Aqua satellite. Since these instruments cannot take measurements ... Full description.
