Sea ice, the thin layer of ice that covers most of the Arctic Ocean and surrounds most of the Antarctic continent, represents a distinctive feature of our planet. The attached flyer, produced by the International Polar Year (IPY) Programme Office, includes a summary of information about sea ice including sea ice formation, movement, monitoring, seasonal patterns, and forecasting. A follow-up activity allows students to investigate the properties of density, temperature, and salinity as they relate to sea ice.
