Use the resources listed below to help you complete this activity.

To learn more about this topic, visit the following web sites:

Permafrost

"What is Permafrost?" - Geological Survey of Canada
Site defines permafrost and uses data from real sites to explain what controls the distribution of permafrost.

"Permafrost: Insights from a new Northern Hemisphere map" - National Snow and Ice Data Center
Defines permafrost, reviews its distribution today, and explains how and why scientists are studying permafrost distribution and what they are learning.

"Permafrost" - Alyeska Pipeline
Site defines each type of permafrost and looks at the effects of permafrost on the Alaskan pipeline.

Sea Ice

" NCEP MMAB Sea Ice Home Page" - NOAA
This page includes links to images that show current and past sea ice distribution around the world. Also includes links for help in interpreting the images.

"Global Sea Ice Extent and Concentration: What sensors on satellites are telling us about sea ice" - National Snow and Ice Data Center
Article reviews how scientists monitor global sea ice and what they are learning from their results.

Icebergs

"Antarctic Ice Shelves and Icebergs" - National Snow and Ice Data Center
Click on links to read about icebergs in the news and view images of ice shelf evolution.

"Icebergs" - National Ice Center
Click on the "Iceburg Pages" link to find additional information and images of icebergs in the Northern and Southern hemispheres.
