  8. Harvard University Life Sciences - HHMI Outreach Summer 2010 Workshop for Biology Teachers Importance of Pack Ice: Denning Bears spend most of their time on pack ice year around. They come ashore mainly when ice melts. Birthing is primarily out on the ice; when on land, time is short and return to the ice is rather quick. http://upload.wikimedia.org/wikipedia/commons/4/4f/Ursus_maritimus_Steve_Amstrup.jpg

  9. Harvard University Life Sciences - HHMI Outreach Summer 2010 Workshop for Biology Teachers Pack Ice Pack ice changes with seasons. Polar bears must migrate with the flows to survive. Food availability also varies with seasons. http://www.nasa.gov/centers/goddard/images/content/157173main_mm6_320px.jpg
